1 550 nm CW LIGHT SOURCE

InGaAsP MQW-DFB LASER DIODE MODULE

WITH WAVELENGTH MONITOR

DESCRIPTION

The NX8570 Series is a 1 550 nm Multiple Quantum Well (MQW)

structured Distributed Feed-Back (DFB) laser diode module with wavelength

monitor function. This device is temperature tunable over 4 × 50 GHz

channels. Available at both C-band (1 530.334 to 1 565.087 nm) and L-band

(1 565.496 to 1 608.760 nm) ITU-T grid wavelengths.

This device is designed as CW light source and ideal for transmission

systems in which external modulators are used.

FEATURES
