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 (1530.334 to 1565.087 nm) and L-band
(1565.496 to 1608.760 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
