MODEL7301 Optical Optic Modem converts E1 electrical signal
into optical data stream for transport over single mode or multimode
fiber optic cables. At the opposite end of the fiber, the optical stream
is converted back into electrical signals of the appropriate interface
such as G.703 &
V.35.
This fiber optic modem extends the
transmission distance up to more than 100Km. The frame format of
MOD-E1 is unframed for E1, so it can be used to transmit E1 signal
of unframed video.
