DESCRIPTION

The NDL7620P Series is a 1 310 nm

λ/4-phase-shifted DFB (Distributed Feed-Back) laser diode coaxial module

with internal optical isolator. Newly developed strained Multiple Quantum Well (st-MQW) structure is adopted to

achieve stable dynamic single longitudinal mode operation over wide temperature range of 0 to +70

°C. It is

designed for STM-16 applications.

FEATURES

• High-speed response

• Peak emission wavelength

• Wide operating temperature range

°C

• Internal optical isolator

•

λ/4-phase-shifted DFB

• InGaAs monitor PIN-PD
