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

• Output power

• Low threshold current

°C

• Wide operating temperature range

°C

• InGaAs monitor PIN-PD

• Based on Bellcore TA-NWT-000983
