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 λp = 1 310 nm
• Optical output power Pf = 2.0 mW
• Wide operating temperature range TC = −40 to +85 °C
• λ/4-phase-shifted DFB
• Side Mode Suppression Ratio SMSR = 35 dB MIN.
• InGaAs monitor PIN-PD
