Rotary Joints

001 MJ2 Series (up to 2 channels)

The dual-pass Fiberoptic Rotary Joint (FORJ) connects two independent fiber channels simultaneously. It allows uninterrupted transmission of optical signals while rotating along the common mechanical axis. Princetel's unique patented design provides customers with significant advantage on size, performance, availability, and cost. The device accommodates two standard multimode fibers. Check out our ZJn or MXn series FORJs for two singlemode channels. 

Note: All insertion loss and return loss measurements are performed by joining the FORJ to the light source through fusion splice (without the use of connectors). Insertion loss of all receptacle type of FORJs, such as RST, RFC, and RFCX, are measured with connectors of similar type. Their return loss is not measured.
