Triax TOFA-822W 8-port 1550 nm PON EYDFA Optical Amplifier

Further details of Triax TOFA-822W 8-port 1550 nm PON EYDFA Optical Amplifier

The Triax TOFA-822W 8-port 1550 nm high-power PON EYDFA combines a low-noise EDFA and a high-power EYDFA. The total output optical power can reach 37 dBm. The 1550 nm optical power per output port is 22 dBm for this version. Each output port has built-in CWDM for multiplexing the CATV signal and OLT PON data flow. The unit is compatible with FTTx PON systems including EPON, GPON and 10GPON.
