JDSU CQF935/208, <5mHz, C-Band DFB WDM Laser Diode Module. Used, remove from un-use OC-192 Module. Please select wavelength you want: 1552.52nm. http://products.jdsu.com/assets/public/pdf/CQF935_208_012604.pdf The JDS Uniphase CQF935/208 series laser is specifically developed for wavelength division multiplexing (WDM) systems, where it is used as a wavelength selected source in combination with an external modulator, such as the LiNbO 3-based Mach-Zehnder. Selected wavelengths comply with ITU recommendations, both in range (channels from 1527.61 to 1610.06 nm) and in channel definition, thus adhering to the 100 GHz grid relative to a frequency of 193.1 THz. Customization of the wavelength spacing to a 50 GHz grid is possible. Each laser's wavelength is accurately measured, and the laser itself is accompanied by a datasheet with the laser performance at the temperature T l where the required wavelength channel is reached. The CQF935/208 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. * 1550 nm WDM distributed feedback laser diode * Polarization maintaining fiber * Built-in thermoelectric cooler * Cooled built-in optical isolator * 1527 - 1610 nm wavelength range * 0.4 nm (50 GHz) spacing optional * Long haul and metro DWDM architectures |
