InGaAsP STRAINED MQW DFB DC-PBH LASER DIODE MODULE
DESCRIPTION
The NDL7701P Series is a 1 550 nm phase-shifted DFB (Distributed Feed-Back) laser diode with single mode
fiber. The strained Multiple Quantum Well (st-MQW) structure is adopted to achieve stable dynamic single
longitudinal mode operation over wide temperature range of –20 to +85 °C.
It is designed for all STM-1 and STM-4 applications.
FEATURES
• Peak emission wavelength
λp = 1 550 nm
• Low threshold current
Ith = 15 mA @ TC = 25 °C
• Wide operating temperature range TC = −20 to +85 °C
• InGaAs monitor PIN-PD
• Based on Bellcore TA-NWT-000983
