JDS Uniphase ErFA1215-PM-B2

The JDS Uniphase ErFA1215-PM-B2 is a polarization-maintaining erbium-doped fiber amplifier (EDFA) module engineered for optical communication systems operating in the 1530–1565 nm wavelength band. Built on PM fiber architecture, it preserves signal polarization state across amplification, delivering stable performance in DWDM and long-haul transmission networks. The module supports pre-amplifier, in-line, and booster configurations with saturated output power ranging from +15 dBm to +22 dBm and small-signal gain of 20–24 dB minimum.
