Model 2893/2894/2895

T3/E3/STS1 to Fiber Modem

S.I.Tech 2893/2894/2895 Bit-Driver is designed to work with T3, E3, or STS-1 systems. Model 2893/2894/2895 is a T3, E3, or STS-1 to fiber optic transmitter/receiver full duplex product implementing T3, E3, or STS-1 protocol. Normal operating data rate for T3 is 44.736 Mbps. (E3 - 34.368 Mbps, STS1 - 51.84 Mbps)

This fiber optic Bit-Driver product eliminates many disadvantages of T3, E3, or STS-1 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 2893/2894/2895 is a rack mounted product allowing easy change from T3, E3, or STS-1 to fiber. Simply disconnect T3, E3, or STS-1 cable and connect to model 2893/2894/2895 input/output port. Model 2893/2894/2895 comes with power supply and status indicators.
