| FORJ: Two-channel fiber optic rotary joint (RJ2 series, multimode) |
|
|
Dual-pass Fiber Optic Rotary Joints (FORJs) connect two independent fiber channels simultaneously.
They allow uninterrupted transmission of optical signals while rotating along the common mechanical axis.
The RJ2 series FORJs feature more spatial internal structure to accommodate larger-core fibers. Like MJ2 series FORJs they also
feature unmatched crosstalk performanc (>55 dB). The
device is designed to accommodate standard and custom
multimode fibers. Check out our
MXn series FORJs for two singlemode channels.
