A mounting system (700/900) for locking two pieces of telecommunications equipment (610/810) to prevent relative sliding therebetween and relative separation therebetween in a direction generally perpendicular to the direction of the relative sliding includes a first locking feature (701/901) defined by a stud (702/902) with a stem portion (708/908) and a flange portion (710/910) having a larger profile than the stem portion (708/908) and a second locking feature (703/903) defined by a slot (704/904) with a receiver portion (712/912) and a retention portion (714/914). The receiver portion (712/912) is sized to accommodate the flange portion (710/910) of the stud (702/902) and the retention portion (714/914) is sized to accommodate the stem portion (708/908) but not the flange portion (710/910) of the stud (702/902). A third locking feature (705/905) prevents relative sliding between the two pieces of telecommunications equipment (610/810) once the stud stem portion (708/908) has been slid within the slot retention portion (714/914) and the stud flange portion (710/910) is out of alignment with the slot receiver portion (712/912).

A photonic integrated circuit may be coupled to an optical fiber and packaged. The optical fiber may be supported by a fiber holder during a solder reflow process performed to mount the packaged photonic integrated circuit to a circuit board or other substrate. The optical fiber may be decoupled from the fiber holder, and the fiber holder removed, after completion of the solder reflow process.

The present disclosure relates to a fiber optic adapter holder that includes a base member and a plurality of upright arms that extend upwardly from the base member. The plurality of upright arms together may define a pocket region that has an open, U-shape. A fiber optic adapter may be received in the open, U-shaped pocket region of the fiber optic adapter holder. When the fiber optic adapter is mounted within the pocket region of the fiber optic adapter holder, a height of the fiber optic adapter holder may be lower than or equal to a height of the fiber optic adapter.

A chassis panel defines one or more rearward-facing, open-ended slots at a rear of the chassis panel. One or more management inserts can be mounted within the open-ended slot along a forward-rearward axis. Cables can be pre-cabled through the inserts prior to being installed at one or more port modules. Accordingly, the port modules can be cabled prior to being installed at the chassis panel without first having to thread the cables through the chassis panel. Alternatively, the cables can be slid directly into the open-ended slots during installation of the port modules.

An optical apparatus having a holding portion and a tubular portion further includes a light source, a light guide which is formed of a medium having a refractive index higher than 1, and an optical converting portion. The light guide has a first light guiding area having an incidence end surface and a second light guiding area having an exit end surface. A diameter of the incidence end surface is larger than a diameter of the exit end surface, and at least a part of the second light guiding area is included in the tubular portion.

A track device is disclosed for providing bending-radius protection and strain relief between a fiber optic cable and a telecommunications closure. The track device includes a first sidewall, and a second sidewall separated from the first sidewall by a curved channel. A secondary wall connects the first and second sidewalk, and open lateral sides are configured to receive one or more fiber optic cables for routing portions of the one or more fiber optic cables inside the curved channel.

An object of the present invention is to provide a versatile optical fiber lateral output device that can deal with various types of optical fiber core wires. An optical fiber input-output device according to the present invention includes: a first jig 11 including a recess portion 22 and an optical input-output means 51; a second jig 12 including a projection portion 23 and a guide groove 24; and a pressing unit 14 configured to apply a pressing force in a direction in which the recess portion 22 of the first jig 11 and the projection portion 23 of the second jig 12 approach each other so as to bend an optical fiber core wire 100. Letting R1 be a curvature radius of the recess portion 22 of the first jig 11, θ1 be a central angle of the recess portion 22, R2 be a curvature radius of the projection portion 23 of the second jig 12, and θ2 be a central angle of the projection portion 23, R2≤R1 and θ2≤θ1 are satisfied.

Devices, assemblies and methods for fixing a telecommunications cable. In certain embodiments, a cable fixation unit that can clamp a cable jacket also includes legs having feet that are mountable to a slotted support structure by inserting the feet into the support structure's slots in a sequence of motions.

A ganging clip for ganging at least two fiber-optic connectors includes a pair of side walls defining a lateral dimension of a top and having a side wall bump on an inside surface. The ganging clip also has at least one partition between the pair of side walls and extending parallel to each of the pair of side walls and extending perpendicularly from the top, a partition bump disposed on each opposite side of the at least one partition, wherein the at least two fiber-optic connectors are retained within the ganging clip at the side wall bumps and at the partition bumps.

The present invention relates to an optical flow cell for a measuring device, having an input light guide with a light exit surface, an output light guide with a light entrance surface, said input light guide and output light guide being integrated with a holder to form an optical flow cell, and wherein the holder extends along a first axis and has a through hole for receiving a flow of a sample fluid, said through hole being transversal to said first axis, and the input light guide and output light guide further are arranged in said holder so that the light exit surface and the light entrance surface extend into said through hole and are arranged to be in optical alignment with each other and at a first distance from each other. The invention also relates to a measuring device having at least one optical flow cell.
