Product Overview:

JDSU CQF976 1535.04nm DFB Laser Overview

The CQF935/208 has been especially developed for use in WDM systems as a wavelength-selected source in combination with an external modulator (such as a LiNbO -based Mach-Zehnder modulator).

The wavelengths that can be selected comply with the ITU recommendation both in range (1527.61 to 1610.06 nm) and in channel definition, adhering to the 100 GHz grid (0.8 nm) relative to a frequency of 193.1 THz (i.e. a wavelength of 1552.52 nm).

Customization of the wavelength spacing to a 50 GHz grid (0.4 nm) is possible. Each laser is accurately measured for wavelength and is accompanied by a datasheet for the laser’s performance at the temperature at which the required wavelength channel is reached. The laser shows excellent side-mode suppression ratios (typically 45 dB) and small linewidths (<5 MHz). The butterfly-packaged laser is provided with a polarization maintaining fiber to facilitate coupling to the modulator and shows excellent thermal stability (e.g. wavelength drift with case temperature is better than 0.001 nm/°C).

Proper Handling and Operation of DFB Lasers

DFB laser diodes are highly susceptible to damage from ESD and from temperatures exceeding their specified safe operating range. The user is advised to use care and proper ESD safety practices when handling them to avoid damage to the laser. A properly rated low noise current source, a low thermal resistance mount and a temperature controller should be used for optimal device performance and reliability.
