JDSU supplies optical photo detectors and receivers for fiberoptic telecommunications and cable television networks. Receivers are used in WDM products for each channel at both ends of the fiberoptic link, as wavelength translation is required. Photo detectors are also used throughout a network to monitor a variety of characteristics including power levels and channel count. Positive Intrinsic Negative (PIN), and Avalanche Photodiode (APD) are offered for data rates from 155 Mb/s to 10 Gb/s. Models are available with transimpedance amplifier (TIA), auto gain control, high gain, high sensitivity, and in several package and connector options. Analog receivers are also available for forward path or return path CATV.
