1550 Laser with Fiber Applications CQF935/708 Series
Uniphase CQF935/708 series laser specifically developed wavelength division multiplexing (WDM) systems, where used combination with external modulator, such LiNbO3-based Mach-Zehnder. Selected wavelengths comply with recommendations, both range (1527.61 1610.06 channel definition, thus adhering grid (0.8 relative frequency 193.1 (i.e., wavelength 1552.52 nm). possible customize wavelength spacing grid (0.4 nm). Each laser's wavelength accurately measured, laser itself accompanied datasheet with laser performance temperature where required wavelength channel reached. CQF935/708 shows high side mode suppression ratios, very relative intensity noise, small linewidths. available standard 14pin butterfly package equipped with polarization maintaining fiber facilitate coupling modulator, shows superb thermal stability. Features 1550 distributed feedback laser diode High power (>40 Polarization maintaining fiber Built-in thermo-electric cooler Cooled, built-in optical isolator 1527 1610 wavelength range (100 GHz) spacing GHz) spacing optional
Applications Hybrid fiber-coax (HFC) networks, cabletelevision (CATV) networks metro architectures where high power, RIN, narrow linewidths required Long haul compensation high-loss passive active components
