NX8571SC816-BA Datasheet PDF - California Eastern Laboratories.

DESCRIPTION
The NX8571 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.
