1310 nm OPTICAL FIBER
COMMUNICATIONS InGaAsP MQW-DFB
LASER DIODE COAXIAL MODULE
NDL7603P
SERIES
FEATURES
• PEAK EMISSION WAVELENGTH:
λp = 1310 nm
• OPTICAL OUTPUT POWER:
Pf = 2.0 mW
• WIDE OPERATING TEMPERATURE RANGE:
-40 to +85
°C
λ/4 PHASE-SHIFTED DFB
• SIDE MODE SUPPRESSION RATIO:

• InGaAs MONITOR PIN-PD
The NDL7603P Series is a 1310 nm
phase-shifted DFB
(distributed feedback) laser diode module with single mode
fiber. The Multiple Quantum Well (st-MQW) structure is adopted
to achieve stable dynamic single longitudinal mode operation
over a wide temperature range of -40 to +85
°C. It is designed
for all STM-1 and STM-4 applications.
