FEATURES
DESCRIPTION
• PEAK EMISSION WAVELENGTH:
λP = 1550 nm
The NDL7701P Series is a 1550 nm λ/4-phase-shifted DFB
(Distributed Feed-Back) laser diode with single mode fiber.
The newly developed strained Multiple Quantum Well (stMQW) structure is adopted to achieve stable dynamic single
longitudinal mode operation over a wide temperature range of
-20 to +85°C. It is designed for all STM-1 and STM-4 applications.
• LOW THRESHOLD CURRENT:
ITH = 15 mA @ TC = 25°C
• InGaAs MONITOR PIN-PD
• WIDE OPERATING TEMPERATURE RANGE:
TC = -20 to +85°C
• BASED ON BELLCORE TA-NWT-000983
ELECTRO-OPTICAL CHARACTERISTICS (TC = -20 to +85°C, unless otherwise specified)
