Pairs of windows are cut into a distribution cable at various points along the length to couple some of the optical fibers of the distribution cable to drop cables. A wrap-type sealing arrangement can seal a first window of each pair. An enclosure-type sealing arrangement can seal a second window of each pair. The enclosure includes a splice tray and cable storage. Optical adapters and/or a passive splitter also may be disposed within the enclosure.

An optical cable includes a plurality of buffer tubes, each of the buffer tubes includes a flexible ribbon, the flexible ribbon including a plurality of optical fibers, the flexible ribbon being wrapped with a finished tape.

The present invention discloses an optical fibre cable clamping apparatus (100) for clamping an optical fibre cable attached to a base comprising an upper clamp member and a lower clamp member, a grooved fibre extension for placing optical fibre elements and two grooved strength member extensions formed in the upper clamp member and the lower clamp member. In particular, the two grooved strength member extension is coupled to attach two strength members.

An apparatus includes a strain relief formed in helical shape and formed with a U-shaped channel. The strain relief can be used around a cable of a component or a spool extension of a fiber tray.

A ferrule-based fiber optic connectors having a connector assembly with a ferrule insertion stop for limiting the insertion of a ferrule into a ferrule sleeve are disclosed. In one embodiment, the fiber optic connector comprising a connector assembly, ferrule insertion stop, a connector sleeve assembly and a female coupling housing. The connector assembly comprises a ferrule and a resilient member for biasing the ferrule forward and the connector sleeve assembly comprises a housing and a ferrule sleeve, where the ferrule of the connector assembly is at least partially disposed in the ferrule sleeve when assembled. The ferrule insertion stop limits the depth that the ferrule may be inserted into the ferrule sleeve.

Fiber optic connectors, cable assemblies and methods for making the same are disclosed. In one embodiment, the optical connector comprises a housing and a multifiber ferrule. The housing comprises a longitudinal passageway between a rear end and a front end, and a rear portion of the housing comprises a keying portion and at least one locking feature integrally formed in the rear portion of the housing.

Devices, arrangements and methods for fixing telecommunications cables relative to a telecommunications closure. Features of the devices and arrangements can make more efficient use of an interior closure volume and enhance a closure's capabilities with respect to handling different types of telecommunications cables and optical fiber routing schemes.

Provided is a medical observation system capable of preventing disconnection of metal cables without increasing the thickness of a braided shield wire. The medical observation system includes a transmission cable including: an optical cable having one or more optical fiber cores; a plurality of metal cables arranged around the optical cable; and a tension member made of a high-strength fiber, and disposed in parallel with an extending direction of the optical cable.

Embodiments of the disclosure are directed to a retrofit kit for a telecommunications cabinet that is configured to house copper electronic equipment. The kit includes a fiber optic apparatus configured to be mounted in an interior of the telecommunications cabinet and a retrofit door configured to be mounted to the telecommunications cabinet to cover the interior. The retrofit door includes a front surface, a plurality of sidewalls extending from the front surface, and a rear surface extending inward from the plurality of sidewalls. The rear surface is spaced apart from the front surface and defines an opening into a cavity of the retrofit door. The fiber optic apparatus and the retrofit door are configured such that when the fiber optic apparatus and the retrofit door are mounted, the at least one cavity of the retrofit door provides volume to accommodate the fiber optic apparatus.

A cable fixation structure for fixing at least a portion of a fiber optic cable to a telecommunications fixture against strain relief includes a base portion configured to be mounted to the telecommunications fixture and a removable cable holder portion that is slidably inserted into the base portion, wherein the cable holder portion is configured for fixing the at least a portion of the fiber optic cable.
