FCD-155E - Ethernet over SDH/SONET ADM


FCD-155E is an STM-1/OC-3 add/drop multiplexer that transports LAN and traditional (TDM) traffic over SDH/SONET networks. When bandwidth granularity of the Ethernet channel is configured to 2 Mbps (VC-12) or 1.5 Mbps (VT-1.5), FCD-155E utilizes the SDH/SONET infrastructure for cost-effective connectivity.


FCD-155E - STM-1/OC-3 Add-Drop Multiplexer

Ethernet over SDH/SONET with TDM support

Used as an add/drop multiplexer on the SDH/SONET ring, the FCD-155E improves bandwidth efficiency by supporting Ethernet over SDH/SONET encapsulation and framing to enable IP channel bandwidth configuration in increments up to 100 Mbps wire-speed.

The FCD-155E is widely deployed by carriers and service providers to leverage their optical bandwidth for revenue-generating Ethernet services, while enterprises, utilities, and campuses use it to provide LAN services over existing fiber-optic infrastructure.



Key Features:


  • STM-1/OC-3 PDH/Ethernet add/drop multiplexer for grooming LAN and legacy (TDM) traffic over SDH/SONET networks
  • Ethernet traffic mapped to 1 VC-3/VC-4/STS-1, up to 3 VC-3/STS-1, up to 63 VC-12 or 84 VT-1.5
  • 1+1 MSP/APS redundancy
  • PDH interface for 8 or 21 E1 (G.703), 8 or 28 T1 (G.703), 1 E3/T3, or 1 E3/T3 with 21/28 E1/T1 ports
  • 10/100BaseT interface with VLAN support and point-to-multipoint switching capability
