Aspects of the present disclosure relate to a modular fiber optic distribution system for enhancing installation flexibility and for facilitating adding components to a terminal housing over time so as to delay cost. The system is configured to allow components (e.g., inserts, add-on modules, etc.) to be readily added to the terminal housing over time to expand capacity, provide upgrades and to provide forward and backward compatibility.

Devices and methods for protecting electro-optical instruments includes a transparent substrate and a conductive film layer on the substrate. The film layer may be perforated with an array of holes and may be configured to attenuate RF/microwave electromagnetic radiation. The devices may include a plurality of optical waveguides having a first end and a second end, wherein the first end of each optical waveguide is disposed over the substrate and passes through a respective hole of the array of holes such that each hole includes at least one optical waveguide. The waveguide may be configured to capture incident light from the second end and guide the incident light to the first end through the hole.

A fiber optic connection system includes a fiber optic connector and an adapter assembly. The fiber optic connector is coupled to the adapter assembly with a fast coupling mechanism. The fast coupling mechanism allows the fiber optic connector to be mounted into the adapter assembly with rotation of the fiber optic connector relative to the adapter assembly less than a full turn.

The present disclosure relates to a fan-out arrangement. The fan-out arrangement may include a main cable that includes a jacket containing a plurality of optical fibers and a plurality of breakout cables that receive the optical fibers of the main cable. The fan-out arrangement may include a fan-out device for transitioning the optical fibers from the main cable to the breakout cable. The fan-out device may include a fan-out housing that includes oppositely positioned first and second housing ends. The fan-out device may also include a fiber transition insert that mounts within the fan-out housing.

Optical fiber connectors for MT/MPO type ferrule assemblies are disclosed, having an overall connector length less than about 32 mm, for example, an overall length of about 18.5 mm for non-reinforced optical fiber cables, and an overall length of about 23.5 mm for reinforced optical fiber cables. In one embodiment, a connector comprises a ferrule assembly, and a non-slideable housing coupled to the ferrule assembly and configured to couple to an adapter corresponding to the ferrule assembly. The connector further includes a lock coupled to the housing and configured to rotate the housing so as to lock and unlock the housing from said adapter. The rotatable lock contains a recess to accept a key to unlock and lock the connector from an adapter.

A sealing enclosure is configured to connect to a mating enclosure. The sealing enclosure loosely receives a connector within a connector volume so that the connector, which may be of a standard type used in electronic or optic data transmission, may be displaced within a plug face at the forward end of the connector volume. The connector may compensate variations in the position of a mating connector with respect to the mating enclosure. The sealing enclosure allows to seal off the connector volume and engage the sealing enclosure with a mating enclosure in a single motion. This is affected by having a cable seal interposed between an inner body and an outer body. If the outer body is moved forward to engage the mating connector, the cable seal is squeezed between the cable and the inner body sealing off the connector volume at the rearward end of the inner body.

The present disclosure relates to a field installable connector system. The connector system includes a factory terminated subassembly including a ferrule terminating an optical fiber of an optical fiber cable. The factory terminated subassembly has a small transverse cross-section to facilitate routing through a duct. The connector system also includes a field installable subassembly including various connector components that can be installed after the factory terminated subassembly has been routed through a duct. The components can be sealed and hardened.

An optical connector assembly a first structure and a second structure, the two structures secured together using a retention structure to form a hybrid assembly. The retention structure uses a slot apex located in a slot channel for securing at least one latch pin of a coupling nut to an adapter housing forming the ingress protected connector without the use of a bias spring. The hybrid assembly is designed to resist water or debris ingress, and may eliminate the use of a bias force to further resist separating the hybrid assembly.
