COMMUNICATIONS COMPONENTS
50 mW 1550 nm CW DFB Lasers with PM Fiber for WDM Applications
CQF935/808 Series
Key Features
• 1550 nm WDM distributed feedback laser diode
• High power (> 50 mW)
• Polarization maintaining fiber
• Built-in thermoelectric cooler
• Cooled, built-in optical isolator
• 1527 - 1610 nm wavelength range
• 0.8 nm (100 GHz) spacing
• 0.4 nm (50 GHz) spacing optional
Applications
• Hybrid fiber-coax (HFC) networks, cable-
television (CATV) networks and metro
architectures where high power, low RIN, and
narrow linewidths are required
• Long haul for compensation of high-loss
passive or active components
The JDS Uniphase CQF935/808 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 LiNbO3-based Mach-Zehnder.
Selected wavelengths comply with ITU recommendations, both in range
(1527.61 to 1610.06 nm) and in channel definition, thus 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).
It is possible to customize the wavelength spacing to a 50 GHz grid (0.4 nm).
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 CQF935/808 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.
