Overview E1 Fiber 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.
Feature
Special two row indicator
Based on self-copyright IC, and software content is high
Realizes random time-slot choice, compose N x 64K (N=1~32) channel
Provides 3 type loop functions: local (ANA), loop to remote (DIG),
command loop (REM)
PBRS code testing function, convenient for installation and test
devices
Remote rate adjustment to remote device (in primary clock status)
when local terminal is in primary clock status
E1 fiber modem can use with V.35 fiber modem that can save a
G.703/V.35 converter
