LASER DIODE

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.

FEATURES

• Peak emission wavelength

• Optical output power

• Wide operating temperature range

−40 to +85 °C

•

λ/4-phase-shifted DFB

• Side Mode Suppression Ratio

SMSR = 35 dB MIN.

• InGaAs monitor PIN-PD
