16 E1 + Ethernet PDH Optical Multiplexer

Orion Telecom Networks Inc.  offers VCL-16 E1 + Ethernet PDH Opical Multiplexer is a point to point high performance optical line transmission equipment, combines 16, 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.

Features and Highlights

  • Integrated E1 Plus Ethernet Optical Multiplexer
  • Compact design that performs E1 and Ethernet channel multiplexing & de-multiplexing to an optical output
  • Provides visible and audible alarm indication
  • Provide Remote power detection (RPD)
  • Low power consumption
  • Orderwire (EOW) channel for end to end installation and maintenance
  • Local and remote loop back test for diagnostics
  • 1+1 Fiber Path protection
  • ALS (Auto Laser Shutdown) facility for eye safety.
  • 10/100M Ethernet Port - 100 Mbps Ethernet data transmission rate complies with IEEE 802.3
  • E1 is available with 120 Ohms (RJ45) or 75 Ohms (BNC)
  • Supports auto negotiation and flow control (pause)
  • Clock options: internal/loop-timed.
