Description

XQF935 series module is an MQW DFB laser module designed for dense wavelength division multiplexing (DWDM) and CATV systems，or test instrument, packaged by 14 PIN butterfly housing and equipped with polarization maintaining (PM) fiber to facilitate coupling to the external modulator.    

The module is used as a wavelength selected source in combination with external LiNbO3-based Mach-Zehnde modulator in CATV HFC networks, especially for super trunking and distribution.  Selected wavelengths comply ITU Grid recommendations, both in range and in channel definition.

XQF935 shows high side mode suppression ratio(SMSR), very low relative intensity noise(RIN),and excellent narrow line width, super thermal stability.
