PDH-8:PDH Fiber Optic Multiplexer fiber to 8 E1

Description
 
8E1 PDH Fiber Optic Multiplexer
 
Introduce
 

DHODT-8 Optical multiplexer is a low cost and high performance optical line transmission equipment, which combines four ITU-T G.703 compliant standard electrical E1, 2.048Mbps signals into an optical data stream for transport over fiber optic cables. Several transmitter options for different cable types and wave-lengths are available. This optical line equipment is developed for transmission in access networks, corporate networks, dedicated networks for railway and power companies etc.

Features
 

Advanced and compact design that performs E1 multiplexing & de-multiplexing and provides a 100Mbit/s optical interface in a single unit.

Built-in AC/DC or DC/DC converter and supervisory microprocessor

Digital clock data recovery for E1 signal

Provides visible and audible alarm indication

Low power consumption

Order wire channel for end to end installation and maintenance

Auxilary data channel in optical line code

Centralized network management with the Topone NMS

High reliability

Flexible installation in various mechanical constructions.

Local and remote loop back test for diagnostics
