4-channel Temperature Tunable Laser with Locker CQF474/508 Series
Features 1550 DWDM distributed feedback laser diode Temperature tunable over channels Integrated wavelength reference module High output power 1527 1610 wavelength range band) Polarization maintaining fiber Cooled built-in optical isolator Built-in thermoelectric cooler
Uniphase CQF474/508 series laser specifically developed dense wavelength division multiplexing (DWDM) systems, where used four-channel, tunable source combination with external modulator, such LiNbO3-based Mach-Zehnder. integrated wavelength reference module stabilizes laser's wavelength. wavelength monitor consists back facet monitor diodes. diode unfiltered conventional power monitor; other filtered provide wavelength dependent output. Selected wavelengths comply with recommendations, both range (for band, 1527 1610 channel definition, thus adhering grid. Each laser's wavelength accurately measured, laser itself accompanied datasheet with laser performance temperature where required wavelength channel reached. CQF474/508 shows high side mode suppression ratios small linewidths. available standard 14-pin butterfly package equipped with polarization maintaining fiber facilitate coupling modulator, shows superb thermal stability.
Applications hybrid fiber-coax (HFC) networks, cable television (CATV) networks, DWDM metro architectures where narrow linewidths required Wavelength division multiplexing (WDM) transmission Sparing restoration Optical add/drop multiplexing Inventory reduction
