7840A DOCSIS 3.1 Low Noise CATV Optical Receiver
●The 7840A DOCSIS 3.1 Low Noise CATV Optical Receiver is a singlemode 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 combination of analog and digital channels (80/30 for example), including HDTV broadcast. The 7840A DOCSIS 3.1 exhibits excellent distortion performance with values well above standards over the entire bandwidth and case temperature specifications (40 MHz – 1200 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 7840A DOCSIS 3.1 Low Noise CATV optical receiver can be used in both 1310 nm and 1550 nm applications being useful at different points of a given network. The 7840A DOCSIS 3.1 is compliant with all criteria of the Restriction of the Use of Hazardous Substances in Electrical and Electronic Equipment (RoHS) guidelines 2002/95/EC.
