PJ2 plastic OFRJs

PJ2 Type Double-Channel Plastic Optical Fiber Rotary Joint (OFRJ)




Plastic optical fibers have the following characteristics: large aperture, easy optical coupling; easy to connect; easy to bend, not easy to break. Therefore, it is very popular in short distance communication system.

PJ2 connects two separate plastic fiber channels at the same time. There is no blind spot when the sliding ring rotates. Precise design, PJ2 can be used underwater. Once the optical fiber is damaged, it is easy to repair and avoid the replacement of the sliding ring itself.

For more channels, please refer to MXn series; RPT series is optional for single channel.
