D2511G Overview
The D2500-Type Digital Isolated DFB Laser Module contains an internally cooled, InGaAsP, MQW, distributed-feedback (DFB) laser designed for 1.5 µm applications. The laser is designed to be used in OC-12/ STM-4 (622 Mbits/s) and OC-48/STM-16 (2.488 Gbits/ s) for long-reach and extended-reach applications. It is also capable of low dispersion penalties (<2 dB) for use with fiber spans exceeding 170 km (3000 ps/nm).
