The S.I.Tech 2890/2891 Bit-Driver is designed to work with T1 or E1 systems. Model 2890/2891 is a T1 or E1 to fiber
optic transmitter/receiver full duplex product implementing T1 or E1 protocol. Normal operating data is 1.544 Mbps.
(E1 - 2.048 Mbps)
This fiber optic Bit-Driver product eliminates many disadvantages of metallic T1 and E1 signals, 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 2890/2891 is a stand alone or rack mount product allowing easy change from T1 or E1 to fiber. Simply
connect T1 or E1 cable to model 2890/2891 input/output port. Model 2890/2891 comes with power supply and status
indicators.
UL Listed. Meets FCC requirements of Class A, Part 15 Computing Devices Standard.
