InGaAsP STRAINED MQW DC-PBH LASER DIODE MODULE
DESCRIPTION
The NX8501 Series is a 1 510 nm phase-shifted DFB (Distributed Feed-Back) laser diode 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 0 to +65 °C.
It is designed for on-line monitoring of dense WDM fiber-optic networks.
FEATURES
• Peak wavelength
λp = 1 510 nm
• Output power
Pf = 2.0 mW
• Low threshold current
Ith = 20 mA @ TC = 25 °C
• Wide operating temperature range TC = 0 to +65 °C
• InGaAs monitor PIN-PD
• Based on Bellcore TA-NWT-000983
