SNFO-1A series Single-channel (SM or MM) rotary joints(FORJ) are the most versatile designs the market has ever seen. The rugged body allows fiber pigtail, ST, or FC receptacles on either the rotor side or the stator side. One can configure the package to fit his need exactly. The standard base models are RPT, RFC, and FST for pigtails, FC/PC, and ST/PC receptacles.features extremely low insertion loss and impressive return loss performance for both singlemode and multimode fibers.SNFO-1A are often used with electronic sliprings, call optical-electrical hybrid slipring, transmit power and high speed data.
