Alcatel 1925 OFA D-WDM, Add Drop MUX Erbium-Doped Fiber Amplifier Description Features The Alcatel 1925 OFA (Optical Fiber Amplifier) is designed to offer excellent performance characteristics for WDM systems in the 1530 - 1560 nm wavelength range. The standard, double-stage 14 dBm unit can be supplemented using external pump modules to achieve outputs of 17 dBm or 20 dBm. A 9 dB mid-amplifier loss port has been designed in to allow for A/DMUX functions, dispersion compensation, etc. Tap couplers at each signal port offer full monitoring capability. The Alcatel 1925 OFA achieves very flat gain in excess of 28 dB, while limiting gain excursion to < 1 dB (typical) over the entire 30 nm wavelength range. Optimization of the architecture yields very low typical noise figures < 5 dB for the 14 & 17 dBm configurations. • Optimized for D-WDM transmission • Dual-stage 14 dBm basic unit can be equipped with external pump modules to offer 17 or 20 dBm • Low-noise figure for optimal SNR • Flat gain across wide bandwidth range • Integrated 9 dB mid-amplifier loss port allows ADM functional customization • Polarization independent & bit-rate transparent • Optical isolators at input, monitor taps, and outputs minimize system susceptibility to reflection • Compact, rugged low profile package Applications • Power booster for D-WDM systems • Optical Add / Drop Multiplexer • Low-noise in-line amplifier for transport systems.
