Description
The JDS Uniphase CQF935/708 series laser is specifically developed for wavelength division multiplexing (WDM) systems, where it is used in combination with an external modulator, such as the LiNbO3-based Mach-Zehnder.
Selected wavelengths comply with ITU recommendations,both in range(1527.61 to 1610.06nm) and in channel definition, thus adhering to the 50 GHz grid (0.4nm) relative to a frequency of 193.1 THz (i.e., a wavelength of 1552.52nm).
Each laser's wavelength is accurately measured,and the laser itself is accompanied by a datasheet with the laser performance at the temperature T,where the required wavelength channel is reached.
The CQF935/708 shows high side mode suppression ratios, very low relative intensity noise, and small linewidths. It is available in a standard 14-pin butterfly package equipped with a polarization maintaining fiber to facilitate coupling to the modulator, and shows superb thermal stability.
