Overview: 7820A CATV Optical Receiver
1 GHz
DATASHEET | MARCH 2012 FIBER OPTICS The 7820A CATV Optical Receiver is a single-mode fiber pigtailed module featuring a low-noise, impedance-matched broadband photodiode and RF amplification. The device receives optical analog and/or digital signals for a range of video broadcast options, and delivers the corresponding RF electrical output. The wide bandwidth supports the delivery of up to 110 CATV analog signals or a bination of analog and digital channels (80/30 for example), including HDTV broadcast. Applications
Video Signal Distribution in HFC and FTTx nodes Video Overlay in Passive Optical Networks (PON). The 7820A exhibits excellent distortion performance with values well above standards over the entire bandwidth and case temperature specifications (40 MHz – 1002 MHz, -30 °C to +85 °C). Moreover, the proprietary impedance-match circuitry between the photodetector and RF amplification stages resolves a number of OEM design obstacles with very low noise performance value, typically less than 4.5 pA/√Hz. The 7820A CATV optical receiver can be used in both 1310 nm and 1550 nm applications being useful at different points of a given network. The 7820A is pliant with all criteria of the Restriction of the Use of Hazardous Substances in Electrical and Electronic Equipment (RoHS) guidelines 2002/95/EC.
