NDL7603P Series
1 310 nm OPTICAL FIBER COMMUNICATIONS InGaAsP MQW-DFB LASER DIODE COAXIAL MODULE
DESCRIPTION
The NDL7603P Series is a 1 310 nm phase-shifted DFB (Distributed Feed-Back) laser diode module with single mode fiber. The Multiple Quantum Well (MQW) structure is adopted to achieve stable dynamic single longitudinal mode operation over wide temperature range of −40 to +85 °C.
It is designed for all STM-1 and STM-4 applications.
