E1 to fiber media converter, E1 fiber optic modem
Description of goods
E1 fiber optic Modem; E1 to fiber media converter
General Introduction
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 (upper row indicate local, and lower row indicate remote)
* 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
* Power: AC 85V - AC 275V or DC±48V
