Definitions
- the present invention is related to fiber optics, and, more particularly, to a fiber optic splice closure and associated methods, as may be used for ring cable network configurations.
- Fiber optic cables and their associated electronics are widely used for providing telephony, data and other related communications services.
- a fiber optic communication system typically offers immunity to electrical noise, a relatively large information carrying bandwidth, and low signal losses.
- the fiber optic cables are readily installed in existing city duct lines, on overhead pole lines, or direct buried in the earth to thereby form cable networks including a plurality of users.
- fiber optic technology is for a ring or loop in a metropolitan or city setting.
- an optical fiber cable as compared to radio, for example, is that an inadvertent cable cut will disrupt communication over the cut cable.
- the cable ring and electronics provide two possible paths of communication. If the cable is cut in the first path, then communications is directed in the opposite direction over the second path of the cable ring. The cut fiber cable may then be repaired and full service restored.
- Such a fiber optic network or system is commonly used in a downtown or metropolitan environment where individual fibers originate at a telephone company or service provider central office and are dropped at various office buildings or other large communications users along the ring.
- the cable of the ring has a relatively large fiber count, such as, for example, from 96 to 144 fibers.
- a typical user may only use two fibers from the ring ⁇ one for transmit and one for receive.
- the electronics can typically switch directions, such as in the event of a cable cut.
- a user is typically connected to the ring at a drop point using two separate splice closures.
- the main closure is connected to adjacent legs of the main or ring cable.
- a majority of the individual optical fibers may be spliced directly between the two adjacent legs. Alternately, a majority of the non-dropped fibers may be directly passed through without splicing.
- a pair of relatively low count fiber optic drop cables are spliced at their first ends to predetermined ones of the fibers from the ring cable in the main closure.
- the low fiber count drop cables may be about 60 feet in length and connect to a drop closure.
- Drop fibers are connected to the ends of the two drop cables, and fibers which are not dropped are spliced together in the drop closure.
- the dropped fibers are connected to electronic equipment, and some fibers may be set aside as spares for future use.
- the main splice closure, the drop cables, and the drop splice closure are typically grouped together in a manhole or vault and consume a relatively large amount of space. In addition to the cost and space required, the large number of splices and the lack of flexibility to add additional drops are significant disadvantages of this conventional approach.
- One typical configuration includes pivoting generally elongate and rectangular splice organizer trays positioned to extend longitudinally within a splice enclosure.
- pivoting generally elongate and rectangular splice organizer trays positioned to extend longitudinally within a splice enclosure.
- Patent No. 5,515,472 to Mullaney et al. discloses such a splice closure.
- the closure also includes a bottom slack storage tray portion for storing buffer tubes.
- U.S. Patent Nos. 5,155,794 to Nolf et al., and also assigned to the assignee of the present invention 5,185,845 to Jones; 4,927,227 to Bensel, III et al.; 5,553,186 to Allen;
- a splice closure comprising at least one first splice organizer tray having one end pivotally connected to a base and extending in a medial portion of a housing; a mounting member pivotally connected to the base adjacent the at least one first splice organizer tray; and at least one second splice organizer tray pivotally connected to the mounting member on a side thereof opposite the at least one first splice organizer tray.
- Each of the types of splice organizer trays preferably includes fiber optic splice supporting portions.
- the splice closure also preferably includes a slack storage tray connected to the base and positioned in the housing adjacent a side of the at least one first splice tray that is opposite the mounting member.
- the splice closure thus provides a compact, yet flexible, closure facilitating drops to a fiber optic ring network.
- the at least one first splice organizer tray is preferably pivotal about a first axis
- the at least one second splice organizer tray is also preferably pivotal about a second axis generally parallel to the first axis
- the housing may have a generally cylindrical shape defining a longitudinal axis generally transverse to the first and second axes.
- the mounting member is preferably pivotal about a third axis also parallel to the first and second axes.
- the at least one second splice organizer tray comprises a plurality of trays connected to the mounting member in side-by-side relation.
- Optical fiber loops preferably extend from the at least one first splice organizer tray to the second splice organizer trays to facilitate connecting to the fiber optic cable ring.
- transport tubes may be used to protect and carry the optical fiber loops which may be preinstalled in the splice closure according to a significant aspect of the invention.
- the second splice organizer trays may have a generally rounded free end portion opposite the mounting member.
- the fiber optic splice supporting portion may be positioned adjacent the generally rounded free end portion of the at least one second splice organizer tray.
- the second splice organizer trays each preferably include fiber guide means for guiding at least one optical fiber.
- the second splice organizer tray comprises a hinge portion opposite the free end portion and pivotally connected to the mounting member, and the fiber guide means defines respective first and second optical fiber ports on opposite sides of the hinge portion.
- Another important aspect of the splice closure, and, in particular, of the second splice organizer trays is the provision of a crossing guide member for guiding at least one optical fiber loop in a configuration to both enter and exit a predetermined port. This permits all of the loop fibers from the cable ring to enter the second trays from a first side, and permits drop connections to the loops from the opposite side of the second trays.
- At least one third splice organizer tray may be pivotally connected to the mounting member to facilitate splicing for random access to at least one optical fiber.
- the third tray preferably has a same configuration as the second trays, but provides yet another desired feature.
- the housing may have a generally cylindrical shape. Accordingly, the free or outer ends of the second splice organizer trays are rounded to correspond to the housing and provide a greater splicing density.
- the slack storage tray may also have sloping or angled sidewall portions to conform to adjacent portions of the cylindrical housing.
- a mounting bracket is preferably carried by the base to support the slack storage tray, and to pivotally support the at least one first splice organizer tray, and the mounting member.
- the base may also include a plurality of cable ports therein for receiving respective fiber optic cables.
- a method aspect of the invention is for making a fiber optic cable network of a type comprising a fiber optic cable routed in a ring configuration, and a plurality of drop locations along the fiber optic cable route.
- the method preferably comprises the steps of: providing a respective fiber optic splice closure as described above, at each of the drop locations; and splicing the at least one optical fiber from the ring to the at least one optical fiber at the at least one first splice organizer tray.
- the method may also include the step of splicing at least one optical fiber from a drop cable to the at least one optical fiber loop on the at least one second splice organizer tray.
- Each fiber optic splice closure may further comprise a slack storage tray connected to the base and positioned in the housing adjacent a side of the at least one first splice tray opposite the mounting member. Accordingly, the method may further include the step of storing slack fiber passing through the splice closure in the slack storage tray. Another advantageous method feature of the invention permits connection to any of the fibers in the ring. More particularly, the method may include the steps of providing at least one third splice organizer tray on the mounting member, and connecting at least one predetermined optical fiber to the ring using the at least one third splice organizer tray.

- FIGS. 2-4 the main components of the splice closure 25 are explained.
- the splice closure 25 includes a generally cylindrical housing 31 indicated in phantom lines in FIG. 2, and a base 32 connected thereto.

- a mounting bracket, generally designated at 33, is connected to the base 32.
- a plurality of cable ports 34 extend outwardly from the base 33 to receive respective fiber optic cables as will also be readily appreciated by those skilled in the art.
- the splice closure 25 includes at least one first or main cable splice organizer tray 37 (FIG. 4) having one end pivotally connected to the base 32 via the bracket 33.
- the splice closure 25 includes three such first splice organizer trays 37. Typical configurations may range from one to three, although those of skill in the art will appreciate that more than three may also be provided for high fiber count cables, for example.
- the number of first splice trays 37 if decreased, could allow for a larger slack storage tray 50, for example.
- the first organizer trays 37 are generally rectangular and elongate, and the trays are positioned to extend in a medial portion of a housing.
- the first organizer trays 37 are pivotally connected at one end to the bracket 33.
- the first organizer tray 37 includes a splice support portion 38 for holding or supporting optical fiber splices 40 as will be readily appreciated by those skilled in the art. For a typical configuration, thirty six fibers could be handled by one first splice organizer tray 37.
- the first splice trays 37 include a planar base 42, opposing sidewalls 41a, 41b extending upwardly from the base, and a proximal end including openings 45 to facilitate securing buffer tubes 46 and transport tubes 47.
- buffer tubes refers to the buffer tubes in a typical loose-buffer tube fiber cable
- transport tubes refers to the protective tubes positioned over the individual one or more fibers for routing between trays as will be further described below.
- the first organizer tray 37 also includes a distal end wall 41c and a series of inwardly extending tabs 42 positioned in spaced apart relation on the sidewalls 41a, 41b.

- the splice closure 25 also includes a slack storage tray 50 (FIG. 3) connected to the base 32 and positioned in the housing 31 adjacent an underside of first splice trays 37.
- the slack storage tray 50 may be used to store buffer tubes 46 that are not accessed at the drop location, for example.
- the slack tray or basket 50 includes a planar base 51, a first pair of opposing sidewall portions 52a, 52b extending at outwardly diverging angles from the base, and an upper pair of generally parallel sidewall portions 53a, 53b connected to the diverging sidewall portions. Inwardly extending tabs 54 are provided to help retain the buffer tubes 46 in the tray.
- a distal end wall portion 52c is also illustratively provided and connected to the base 51.
- Plastic tie wraps 56 are illustratively used to secure the slack buffer tubes 46 in position.
- the splice closure 25 also includes a mounting member 60 pivotally connected to the base 32 via the bracket 33, and overlying the uppermost first splice organizer tray 37.
- the mounting member 60 in the illustrated embodiment is in the form of a generally rectangular planar member adapted to carry the illustrated plurality of second splice organizer trays 65.
- the mounting member 60 may also include portions for routing and securing buffer/transport tubes, as well as individual fibers.
- the second or drop splice organizers 65 include a pair of hinge pins 66 (FIG. 5) which cooperate with mating recesses in the mounting member 60 to pivotally mount the second trays. Accordingly, the second splice organizer trays 65 may also be pivoted to permit access to a particular tray as will be readily understood by those skilled in the art.
- the second splice trays define respective first pivot axes that are parallel to the second pivot axes of the first splice trays 37.
- the first and second axes are transverse to the longitudinal axis defined by the cylindrical housing 31.
- the mounting member 60 also has a pivot axis transverse to the longitudinal axis of the housing 31, and parallel to the first and second axes of the first and second splice organizer trays.
- the second or drop splice trays 65 are pivotally connected to the mounting member 60 on a side thereof opposite the first splice organizer trays 37.
- the second splice trays 65 are arranged in side-by-side relation.
- the number of such slice trays 65 may be as few as one to as many as twenty-four, for example, as will be appreciated by those skilled in the art. Greater numbers could also be accommodated.
- the splice closure 25 thus provides a compact, yet flexible, closure facilitating drops to a fiber optic ring network 20 as shown in FIG. 1.
- a relatively high density of splices can be accommodated and with partitioning to greatly increase ease of installation and later reconfiguration flexibility.
- the second splice tray 65 may have a rounded free or outer end 65 as illustrated.
- a fiber splice support area 67 may be provided adjacent the free end to hold one or more optical fiber splices as will be readily appreciated by those skilled in the art.
- the shape of the rounded outer end 68 corresponds to the adjacent interior wall portions of the housing 31 to thereby increase the compactness of the splice closure 25.
- one or more optical fiber loops 70 preferably extend from a first splice organizer tray 37 to a predetermined one of the second splice organizer trays to facilitate connecting to the fiber optic cable ring.
- the fiber loop 70 would typically be routed from a second tray 65 a first tray 37.
- the installer would then connect predetermined fibers from the main cable 26 (FIG. 1) to the ends of the loop 71 on the first tray 36.
- predetermined fibers from the main cable 26 (FIG. 1) to the ends of the loop 71 on the first tray 36.
- forty-eight loops would be provided to permit fibers 1-48 to be available to be dropped by connection at the second splice trays 65. Accordingly, if fibers 1-4 were to be connected or dropped at a given drop location, for example, the drop splices would be stored on the respective second splice organizer tray 65.
- This relatively simple logic can be readily extended by those skilled in the art to configure a functioning network and with reduced cost and use of space, as well as greatly enhanced flexibility as compared to prior art approaches.
- the second splice organizer trays 65 each preferably includes fiber guide means for guiding at least one optical fiber.
- the second splice organizer tray 65 comprises the hinge pins 66 defining a hinge portion or end 71 opposite the free end portion 68 and pivotally connected to the mounting member 60.
- the fiber guide means is provided by a horizontal base 77, vertically extending exterior sidewalls 72, interior sidewalls 73, and horizontally extending tabs 74. Paired horizontal tabs 75 define a slotted opening 76 therebetween that can be used to position the fibers under the tabs.
- Those of skill in the art will appreciate that other similar structures may be provided to guide the fibers so that their minimum bend radius is not violated.
- the guide means also define respective first and second optical fiber ports 80, 81 on opposite sides of the hinge portion 71. As shown in FIG. 6, the guide means cooperate so that the loop 70 from a first splice tray 37 can be routed into and out of the port 80. Accordingly, organization of fibers is simplified as, for example, all of the fibers from the first trays 37 can be fed to a common side of the second trays 65. In addition, as will be explained below with reference to FIG. 7, the fibers to the drop cable can be arranged to enter from the opposite port 81 to also facilitate a tidy and efficient routing of fibers as will be readily appreciated by those skilled in the art. Focusing now on the central portion of the second splice tray 65 as shown in FIG.
- the fiber loop 70 is routed from the port 80 along the left sidewall 72, along the interior sidewall 73, along the right sidewall 72, along a portion of the bottom sidewall, and up and through the illustrated crossing guide member 85.
- the crossing guide member 85 includes four body portions 85a-85d that define crossing fiber channels through a central portion of the tray to permit the fibers to change rotational directions.
- the body portions 85a-85d define rounded outer surfaces for contacting the fibers routed thereover.
- Horizontally extending tabs 86 are also provided to help retain the fibers.
- each second splice organizer tray 65 can typically hold more than one fiber; however, for clarity of explanation only a single fiber loop 70 is shown in FIG. 6.
- FIG. 7 a second splice organizer tray 65 is shown after the loop fiber 70 has been cut, and a splice 88 has been made to a drop optical fiber 90.
- a splice 88 has been made to a drop optical fiber 90.
- the fiber 70 which is spliced to the main cable at a first splice organizer 37 extends through the left port 80, and the fiber 90 to the drop cable extends through the right port 81 in the illustrated embodiment.
- One slack loop for each fiber is also shown, although multiple such slack loops can be accommodated
- the invention advantageously, provides at least one third splice organizer tray.
- a tray preferably has the same configuration as the second splice trays 65 described in detail above.
- the third splice tray may be a designated one from the series as shown in FIG. 2, or may be positioned in spaced relation on the mounting member to more readily permit the technician to recognize its different function.
- a method aspect of the invention is for making a fiber optic cable network 20 of a type comprising a fiber optic cable 26 routed in a ring configuration and a plurality of drop locations along the fiber optic cable route.
- the method preferably comprises the steps of: providing a respective fiber optic splice closure 25 as described in detail above, at each of the drop locations; and splicing the at least one optical fiber from the ring to the at least one optical fiber at the at least one first splice organizer tray 37.
- the method may also include the of splicing at least one optical fiber from a drop cable 27 to the at least one optical fiber loop 70 on the at least one second splice organizer tray 65.
- Each fiber optic splice closure 25 may further comprise a slack storage tray 50 connected to the base 32 and positioned in the housing 31 adjacent a side of the at least one first splice tray 37 opposite the mounting member 60. Accordingly, the method may further include the step of storing slack fiber passing through the splice closure 25 in the slack storage tray 50.
- Another advantageous method feature of the invention permits connection to any of the fibers in the cable ring 26. More particularly, the method may include the steps of providing at least one third splice organizer tray on the mounting member 60, and connecting at least one predetermined optical fiber to the ring using the at least one third splice organizer tray.
