F520 Optical Transport
F520 DRA Raman Amplifier
TORmem hardware
TORmem F520 DRA (distributed Raman amplifier) card — pumps gain into the transmission fiber itself to extend reach and OSNR on long-haul DWDM spans of the F520 transport platform.
A distributed Raman amplifier (DRA) injects pump power into the transmission fiber so the span itself provides low-noise gain, improving OSNR and extending reach beyond what EDFA alone allows — the tool for the longest spans. The F520 DRA card slots into the F520 chassis and works alongside the EDFA line. Pump configuration is matched to your span loss and link budget — exact configuration confirmed at quote.
