An optical splitter, a combiner and a device.

A certain number of the distribution fibers from a particular optical splitter extend in an upstream direction of the fiber cable, and the remaining distribution fibers from that optical splitter extend in a downstream direction.

A 1XN (or NX1) optical connector (300) for steering light is provided, which may be formed into an optical cross connecter.

The OLT (301) is connected with the optical module of the optical time domain reflectometer (303), and the optical module of the optical time domain reflectometer (303) is connected with the light splitter (302).

A three dimensional optical circuit (200) featuring an optical manifold for organizing, guiding and protecting individual optical fibers is shown.

An optical splitter module includes a housing wherein an input optical fiber and an output optical fiber pass through a single opening in the housing.

The optical manifold may be used in conjunction with a number of connections or terminations to form a various optical modules.

An optical insulator is installed between the output of the source and the input pole of the tripolar optical splitter, one output pole of which is connected to the common input of an optical switch.

The plural node elements may include, but are not limited to, one of plural routers and an optical cross-connect.

An optical communication assembly has an optical cross connect coupled to a first, a second, a third and a fourth set of optical fibers.

The switch (100) includes an Optical Cross-Connect (OXC) (101) having F1 input ports (102) and F2 output ports (112).

The second optical splitter is formed on the substrate and combines a first rotated incident mode and a second rotated incident mode to reform the incident optical signal at an output port (113).

A layered optical cross-connect switches signals from a first set of optical fibers to a second set of optical fibers.

Provided is an optical cross-connect device whereby, in an optical node in an optical network, it is possible to easily support even an increase in the number of optical fibers between optical nodes.

The R&M Optical Distribution Frame (ODF) is being used as the platform for the distributors.
