PGE 608 16 EDFA Gain Block for DWDM Applications Key Features • Operating wavelength window: 1543-1558 nm • Gain flatness < ±0.5dB • Low noise figure, typ. <5 dB • +11 dBm output power • Input and output monitor diodes • Optical output monitor • Operating temperature range: -5 °C to 70 °C • Multisourced footprint • Small size (120x80x15) mm Applications • Pre-amplifier in single-channel or DWDM networks Description The DWDM gain block is intended to be used as a pre-amplifier in WDM / DWDM networks. The gain block has input and output power monitoring. The input and output ports have isolators to attenuate spurious reflections in the system. External electronic circutry is needed for biasing the pump laser and for controlling the pump laser temperature. Heat sink is provided via the bottom surface. 1 PGE 608 16 Optical input signal Optical output signal Optical gain Output power monitor Input power monitor 28 pin electrical interface Optical output power monitor Figure 1.
