The S.I.Tech 2390/2391 Bit-Driver is designed to work with T1 or E1 systems. Model 2390/2391
is a T1 or E1 to fiber optic transmitter/receiver full duplex product implementing T1 or E1 protocol. Nominal
operating data rate is 1.544 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 2390/2391 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 2390/2391 input/output port.
