C-band DWDM EDFA Pre-Amplifier Erbium Doped Fiber Amplifier

DWDM Rackmounted EDFA

STEDFA-SO-t-CW40-pp/Ggg(V)-(abc)-x-y is a family of gain-flattened unidirectional EDFA. Its working wavelength is normally C-Band (1529~1561nm), special working wavelength range can be discussed with Sino-Telecom. Because of adopting optimal design of optical path, it can amplify the C-Band signal with or w/o middle stage access (MSA), at fixed gain or variable gain, which brings great flexibility for the network application. Besides, for adopting high quality GFF and reasonable design of optical path, it achieves very good gain flatness and very low noise figure. Optical supervisory channel (OSC) is optional function integrated in the rack. It can be dropped /added outside, or bypass internal, or amplified by OSC OEO module.

The EDFA has the world's top class pump laser and erbium-doped optical fiber. Perfect AGC, APC and ACC control, excellent design in ventilation and heat-dissipation ensure the long life and high reliable work of pump laser. The laser will switch off automatically if optical power is missing. RS232 and RJ45 offer serial commutation and SNMP network management port, which make the remote control available.
