Multi Channel Fibre Optic Rotary Joint FORJ | Princetel MRn series

Supplier: LightOptronics Aust.

The MRn series multi-pass Fibre optic Rotary Joints (FORJs) carry the largest channel count in Princetel's FORJ line up.

Price Guide: POA

20-50 independent fibre channels are offered as standard options. The most common is 24- channel version. Loss and back reflection are uniform across all channels. There is no channel "drop off" or "blind spot" during rotation. They also feature low crosstalk performance (<-60dB) for both single and multi channel fibres.

Like our other multi-channel FORJs, all channels can accommodate either singlemode or multimode fibres. It is also possible to combine the two types of fibres in one device across three optical windows (850, 1310, and 1550 nm). As a rule of thumb, always consider lower channel count first for smaller size, lower cost, faster delivery, and easier handling. However, if massive channel count is necessary, Princetel's MRn series FORJs offer the best solution.
