OPTICAL FIBER MANAGEMENT TRAYS AND ASSEMBLIES WITH FEATURES FOR IMPROVED ROLLABLE FIBER RIBBON ROUTING
An optical fiber management tray, such as a splice tray, and related assemblies. The tray includes fiber guiding features for improved routing of reliable ribbon fiber on the tray. In some embodiments, a fiber management tray is configured to receive a routed fiber ribbon and a plurality of routed individual optical fibers, the tray being further configured to support a plurality of individual fiber splices that splice the fibers of the ribbon fiber to the individual fibers.
Light weight fiber optic splice and fiber management system
The present disclosure relates to an optical splice package for splicing together first and second optical fibers or first and second sets of optical fibers. The optical fibers have elastic bending characteristics. The splice package includes a splice housing including a mechanical alignment feature for co-axially aligning ends of the first and second optical fibers or sets of optical fibers within the splice housing. The splice housing contains adhesive for securing the ends of the first and second optical fibers or sets of optical fibers within the splice housing. The optical package has a weight less than a spring force corresponding to the elastic bending characteristics of the first and second optical fibers or sets of optical fibers.
Pluggable optical module and optical communication system
An object is to be capable of housing an optical fiber that connects between components not to exceed a bending limit of the optical fiber in a housing of a pluggable optical module. A pluggable electric connector (11) is configured to be insertable into and removable from an optical communication apparatus (93). An optical output module (12) outputs an optical signal (LS1) and a local oscillation light (LO). An optical reception module (13) outputs a communication data signal (DAT) generated by demodulating using the local oscillation light (LO). A pluggable optical receptor (15) is configured in such a manner that optical fibers are insertable thereinto and removable therefrom. A first optical fiber (F11) is connected between the optical output module (12) and the pluggable optical receptor (15). A second optical fiber (F12) is connected between the optical output module (12) and the optical reception module (13). A third optical fiber (F13) is connected between the optical reception module (13) and the pluggable optical receptor (15). Optical fiber housing means winds extra lengths of the first to third optical fibers (F11 to F13) around a guide.
Telecommunications distribution elements
A telecommunications rack system includes a first element defining splice locations and a second element defining adapters for receiving connectorized cabling, wherein the first and second elements are positioned on the same rack. A first end of a fiber optic pigtail is spliced at and extends from the splice locations of the first element. A second end is connectorized with a fiber optic connector that is coupled to an adapter of the second element. The pigtail extends between the first and second elements. A cable manager is removably mounted at the side of at least one of the first and second elements. The cable manager defines a U-shaped passage including ends that open toward one end of the elements and a closed end opposite the open ends. The U-shaped passage defines cable pass-throughs adjacent the closed end for transitioning cables from inside the U-shaped passage to an exterior thereof, wherein the connectorized pigtail is passed at least through a portion of the U-shaped passage and out the cable pass-through going from the first element to the second element.
PLUGGABLE OPTICAL MODULE AND OPTICAL COMMUNICATION SYSTEM
An object is, in a pluggable optical module, to compactly house an optical fiber used for connecting optical components in a housing in which a plurality of optical components are mounted. The pluggable optical module (100) includes: a plurality of optical components, a printed circuit board (51); one or more optical fibers; and optical fiber housing means (14). All or a part of the plurality of optical components are mounted on the printed circuit board (51). One or more optical fibers connect between the plurality of optical components. The optical fiber housing means (14) includes a guide that is disposed on a plate-like member and can wind the one or more optical fibers, and mounted to be stacked with the printed circuit board (51) on which the optical components are mounted and all or a part of optical components other than the optical components mounted on the printed circuit board (51).
FUSION SPLICING SYSTEM, SERVER, FUSION SPLICER, INFORMATION TERMINAL, AND PROJECT MANAGEMENT METHOD
A fusion splicing system includes a fusion splicer configured to perform fusion splicing of optical fibers, and a server configured to receive fusion splicing data pertaining to the fusion splicing from an information terminal capable of communicating with the fusion splicer, or the fusion splicer via a communication network. The fusion splicing data includes first identification information for identifying a project to which the fusion splicing belongs. The server retains second identification information related to a registered project registered in advance, compares the first identification information with the second identification information, and interrelates the fusion splicing data with the registered project indicated by the second identification information when the first identification information coincides with the second identification information.
Fiber optic closures and support structures and assemblies for fiber optic closures
Closure-mounted support structures and associated assemblies for supporting fiber optic management devices within a fiber optic closure defining a closure volume. The support structures are adapted to receive and hold axially distal portions of protection tubes that hold and protect portions of optical fibers as they are routed through the closure volume, and also to support optical fiber management trays into which the optical fibers can be routed upon exiting the protection tubes.
Enclosure with restricted access region
A re-enterable enclosure has a cover arrangement removably disposed within the interior between a rear wall and an access opening to separate the interior into a restricted access region and an unrestricted access region. The cover arrangement extends over the restricted access region to inhibit access to the restricted access region from the access opening. First and second entrances to the restricted access region are provided from the unrestricted access region. The second entrance is different from the first entrance. In some implementations, a termination field is provided at a first side of the restricted access region and a splice tray is provided at a second side of the restricted access region.
HEAT MANAGEMENT SYSTEMS FOR ENCLOSURES FOR POWER AND OPTICAL FIBER NETWORKS
