FEATURES
DESCRIPTION
• PEAK EMISSION WAVELENGTH:
λP = 1550 nm
The NDL7705P Series is a 1550 nm phase-shifted DFB
(Distributed Feed-Back) laser diode module with optical
isolator. Newly developed strained Multiple Quantum Well
(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-1and STM-4
applications.
• OPTICAL OUTPUT POWER:
Pf = 2.0 mW
• INTERNAL OPTICAL ISOLATOR
• InGaAs MONITOR PIN-PD
• WIDE OPERATING TEMPERATURE RANGE:
TC = -40 to +85°C
• λ/4 - PHASE-SHIFTED DFB
ELECTRO-OPTICAL CHARACTERISTICS (TC = -40 to +85°C, unless otherwise specified)
