Fiber optic splitter modules and systems

In one instance, a fiber distribution hub includes a fiber distribution cabinet and a fiber optic splitter module coupled to and disposed within the fiber distribution cabinet. The fiber optic splitter module has horizontal (perpendicular to gravity) top and bottom rails and vertically (parallel to gravity) mounted splitter assemblies. In some instances, the distribution ports are downwardly oriented to facilitate cable management. Cable management systems are also included. Other aspects are presented.

With respect to fiber optic structured cabling, dense optical termination and patching platforms, systems, and methods herein involve using an optical-connector adapter cassette that has double rows of adapters on a front portion and at least one goose-neck portion that transitions to a single row of adapters on a rear portion. The double rows of adapters may have virtually no geometry between them. Two cassettes may be cantilevered at the front of a fiber-optic enclosure. The systems includes other aspects.

An optical tap includes a support with a first port facing a first ferrule supporting a first fiber along a first axis. A beamsplitter is connected to the support and intersected by the first axis. A second port is fastened to the support and facing a second ferrule supporting a second fiber along a second axis that intersects the beamsplitter. A third port is fastened to the support and facing a third ferrule supporting a third fiber along a third axis that intersects the beamsplitter, wherein the beamsplitter splits a first light signal from the first port to sends first and second portions of the first signal to the second and third ports, respectively. When the beamsplitter may optionally be configured as a polarizing element and include elements configured to rotate relative to each other to change a ratio of the first and second portions. The optical tap may optionally include a light intensity controlling device located in an optical path between the beamsplitter and at least one of the second or third ferrules. Optionally, a first collimating lens is configured to expand a first light beam that is substantially aligned with the first axis, and a second collimating lens is located between the beamsplitter and the second port, and configured to contract the second portion of the expanded first light beam to the second port.

A communications interconnection system includes: a communications rack having a pair of upright members; a patch panel mounted to the upright members, the patch panel having mounting locations for telecommunications connectors; and a cable management system mounted to the rack. The cable management system comprises a cable mounting member having a cable securing portion and a pair of arms attached to the cable securing portion, the arms being substantially parallel to each other and slidably mounted relative to the panel to enable adjustment of the distance between the cable securing portion and the communications rack. This configuration can enable the cable management system to be used with communications racks of different sizes and designs.

An MPO connector adapter to connect a first female MPO connector to a second female MPO connector includes a housing. An adapter ferrule is retained within the housing. First and second alignment pin sections extend from a first face of the adapter ferrule to mate with guide holes of the first female MPO connector. Third and fourth alignment pin sections extend from an opposite face of the adapter ferrule to mate with guide holes of the second female MPO connector. Optical fibers within the adapter ferrule couple optical signals from the first female MPO connector to the second female MPO connector.

A network interface unit (NIU) for a modular workstation includes a housing. One or more input network adapters on the housing receive input connectors of a first multi-network cable that is connected to a distribution network. One or more output network adapters on the housing receive output connectors of a second multi-network cable that is connected to another NIU of another modular workstation to provide for a daisy chain connection. One or more workstation adapters are provided on the housing for providing connections to one or more networks of various security levels. Cables that are connected to one or more CPUs or telephones of the workstation are connected to respective ones of the workstation adapters. The workstation adapters of the NIU may provide one or more of visual, physical, and geographical verification and segregation of the network connections to enhance the integrity of the security of the various networks available at the NIU.
