1.74 FIB1-E1/T1
The FIB1-E1 is a fiber media transport for G.703 E1 transmission. The BNC
model provides unbalanced 75 Ohm coaxial connections while the RJ-45 model
provides balanced 120 Ohm connections over twisted pair wiring. The FIB1-T1 is a
fiber media transport for G.703 T1 transmission and features an RJ-45 connector for
connection to 100 Ohm twisted pair wiring. All media converters are available with
either multi-mode or single-mode optical tranceivers and with connectors for SC, ST,
or FC. In single mode, WDM (Wave Division Multiplexing with SC connector) is also
available in 20 or 40KM reach which will provide the ability to transmit and receive
data using only a single optical fiber. A unique feature of the FIB1-E1 and FIB1-T1
converters is the use of a common PCB card which may either be used as a
standalone converter (FIB1 series) or placed in the FRM301 rack.
