EDFA Erbium-Doped Fiber Amp Card – 48ch C-Band
A C-band erbium-doped fiber amplifier card that boosts up to 48 DWDM channels at 100 GHz or 96 at 50 GHz, with flat gain, low noise and one-slot 0.5RU mounting.
Description
Overview
The EDFA is an erbium-doped fiber amplification card. Its main function is to compensate the power of the signal light in the transmission link, and it can amplify the optical signals of up to 48 channels (channel interval of 100 GHz) or 96 channels (channel interval of 50 GHz) at C band at the same time.
It has the characters of flat gain, locked gain and low noise figure, and is an indispensably important component for DWDM systems, future high-speed systems and all-optical network long-distance transmission.
Four amplifier types are available — OBA, OLA, OPA and R/B-EDFA — each with its own minimum input power, maximum output power and maximum gain, so the card can be matched to booster, line, pre-amplifier or remote-pumped positions.
EDFA Key Features
- Four EDFA types in one card family — OBA, OLA, OPA and R/B-EDFA
- Amplifies up to 48 channels at 100 GHz spacing or 96 channels at 50 GHz spacing in the C band
- Standard working wavelength range 1529nm~1561nm, extension type 1528nm~1568nm
- Flat gain and low noise figure — noise factor below 5.5dB and gain flatness below 1.5dB
- Maximum gain of 12dB for OBA or 25dB for OLA, OPA and R/B-EDFA
- Optional built-in dual pump for signal secondary amplification
- Gain locking and transient control technology plus automatic shut-off of the output optical power
- Real-time monitoring of optical power, optical pumping and temperature
- Pump shutdown threshold and automatic recovery time can be set
- LC/UPC optical interface, one 0.5RU slot in OSP3800 series chassis, 30W maximum power consumption

Deployment Scenarios
- Boosting the transmit power of a C-band DWDM link at the head-end
- Compensating span loss in long-distance and all-optical network transmission
- Pre-amplifying weak signals ahead of the receiving terminal
- Remote-pumped or bidirectional amplification positions that need R/B-EDFA
- Links that must keep flat gain across 48 channels at 100 GHz or 96 channels at 50 GHz
