QAMnet wEDFA series are Gain-Flattened Erbium Doped Fiber Amplifiers designed for amplifying HFC, RFOG and FTTH applications that incorporates multiple lasers with different wavelength. These laser are typically defined as Dense Wavelength Division Multiplexing (DWDM) lasers. When standard EDFA is used to amplify multiple DWDM lasers, the output power level of various lasers will vary according to the gain profile of erbium fiber. This gain variation can be as much as 6dB in magnitude. wEDFA series has unique features of dual-stage amplification and internal Gain Flattening Filter (GFF) to compensate this gain variation. These designs enable wEDFA to reduce the gain variation down to +/- 0.5dB over and making all DWDM lasers have nearly equal level of power.
wEDFA are very versatile EDFA. Depending on the input power level of each channel, wEDFA can amplify from single laser to 32 DWDM lasers. wEDFA series are powerful amplifier. Each wEDFA incorporates four pump sources, two 980nm lasers and two 1480nm lasers. With all four pump lasers set to maximum operating current, the total output power level of wEDFA can reach +23 dBm (200mW).
Housed inside standard 1RU height rack mount case, wEDFA has a simple to use control interface and easy to read LCD display. wEDFA series are constructed with 100% qualified components to ensure 15+ years of continuous operating life. wEDFA series is covered under three year standard warranty. QAMnet’s technical team provides full products support and applications development consultation.
