JDSU CQF935/508, 20mW 1531.12, 1534.25, 1534.7, 1535.03, 1535.82, 1540.55, 1542.93, 1547.3, 1547.5, 1547.71, 1548.4, 1549.3, 1550.11, 1550.55, 1551.72, 1552.52, 1555.9, 1559.79. The JDS Uniphase CQF935/508 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 CQF935/508 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. * C Band 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 |
