Twinax to Fiber Optic Multiplexer

S.I. Tech Model 9302 Twinax to Fiber Optic Multiplexer

S.I Tech Model 9302 multiplexer Bit-Driver is designed to work with IBM System 3/X, AS/400, and 5251 controller using twinax cable. Model 9302 Bit-Driver is a 2 channel twinax to fiber optic transmitter/receiver full duplex multiplexer product implementing IBM Protocol. Normal operating data rate is 1 Mbps on each port.

This fiber optic Bit-Driver product eliminates many disadvantages of twinax, especially EMI/RFI, ground loops (electrical isolation with fiber), high attenuation (high signal loss), limiting distance between nodes of system, and potential lightning damage outdoors between buildings.

S.I.Tech Model 9302 is a standalone product allowing easy change from twinax to fiber: Simply disconnect twinax cables and connect to model 9302 input/output port. Model 9302 comes with power supply and status indicators.
