4 E1 Optical Multiplexer plus
Ethernet with SNMP


Product Overview

Orion Telecom Networks Inc. offers 4 E1 + Ethernet - Optical Multiplexer is a high performance optical line transmission equipment, combines 4, ITU-T G.703 compliant standard electrical E1s plus 100BaseT ethernet signal into an optical data stream for transport over fiber optic pairs. Several transmitter options for different cable types and wave-lengths are available. 1+1 optical path redundancy is offered and available as an option.

The option of 1+1 Optical Redundancy (Protection Switching), the transmission automatically switches to a 'standby' optical link in the event of a failure of the 'primary' optical link.
