Raman Amplifier in Optical Fiber

Distributed Raman amplification (forward/backward) in the transmission fiber to boost OSNR and extend span length on C-band DWDM links—seamlessly pairs with BA/LA/PA EDFAs for ultra-long reach.

Multiple Choice

The Raman Amplifier in Optical Fiber uses in-situ (distributed) pumping to raise signal power inside the line fiber itself, offsetting attenuation before the EDFA stage. Available as Forward Raman (FRA), Backward Raman (BRA), or bidirectional configurations, it improves OSNR, increases single-span distance, and can reduce the number of inline sites—ideal for metro-long haul and backbone DCI. Closed-loop pump control maintains stable operation during channel add/drops, while transient suppression preserves multi-wavelength balance. Hardware interlocks, keyed enable, and alarms protect personnel and plant. The unit integrates neatly with HYD optical layers (MUX/DEMUX, OLP, OCM/OTDR) and BA/LA/PA EDFAs to deliver resilient, high-reach performance.

  • Modes: FRA / BRA / bidirectional distributed Raman

  • Benefits: higher OSNR, longer spans, fewer inline sites

  • Control: closed-loop pump APC, fast transient suppression; optional VOA

  • Safety: laser interlocks, key switch, back-reflection protection, alarms

  • Interfaces: LC/UPC standard (SC variants optional); OSC/OTDR pass-through options

  • Fiber: G.652 (typical); options for G.654 long-haul routes

  • Management: Web/CLI/SNMP; Netconf/YANG (where applicable)

  • Form factors: 1U rack module or plug-in card for HYD 1U/2U/5U platforms

  • Use cases: metro-LH spans, backbone DCI, pre/post-EDFA enhancement
