Erbium Doped Fiber Amplifiers

The Sentior™ 19000 Rack Mounted Raman Amplifier incorporates three parallel, non-dependent eye-safety mechanisms, which shuts-down the amplifier in case of fibre breakdown, open connectors or broken fibre even at a distance of few tens of km from the unit. This unique and comprehensive safety mechanism is extremely important due to the Raman amplifier's high powered light.It is fully controlled electronically and is built of triple or dual pump (two wavelengths) for C or L band.

Features include:

Flattening adaptation mechanism based on fibre type and pump power<.br>

Gain evaluation to verify amplification effectiveness (fibre state)

Alerts for fibre deterioration & gain reduction
