Product selection guide

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. The device accommodates either multimode fibers or singlemode/multimode fiber combination. Check out our MXn series FORJs for two singlemode channels. Princetel's unique design has raised the standard for size and performance of two-channel FORJs.
