1 / 6 page DATASHEET | MARCH 2012 FIBER OPTICS | REV 2012.03 Information contained herein is deemed reliable and accurate as of the issue date. EMCORE reserves the right to change the design or specification at any time without notice. Applications Video Signal Distribution in HFC and FTTx nodes Features 5 MHz – 200 MHz Bandwidth Supports the Return Path CATV Application. Excellent RF Frequency and Distortion Characteristics for High Linearity. Low Noise (2 pA/√Hz typ.) Low Power Dissipation (0.85 W max.) as well as High RF Output. RoHS Compliant Internal Prorietary Impedance Match Circuitry (75Ω) Robust Small Package with Single-Mode Fiber Pigtail and Connector Options Wide Operating Case Temp Range, -30O to + 85OC The 7820C 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 in the 200 MHz HFC return path bandwidth. The 7820C exhibits excellent distortion performance with values well above standards over the entire bandwidth and case temperature specifications (5 MHz – 200 MHz, -40 °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 2 pA/√Hz. The 7820C Return Path HFC CATV optical receiver can be used in both 1310 nm and 1550 nm applications being useful at different points of a given network. The 7820C is compliant with all criteria of the Restriction of the Use of Hazardous Substances in Electrical and Electronic Equipment (RoHS) guidelines 2002/95/EC. Performance Highlights Parameter Limits Frequency Range 5 – 200 MHz Noise 2 pA/√Hz (typ) DTO -70 dBc (typ) DSO -65 dBc (typ) Optical Input Power Up to +1dBm Wavelength 1260 – 1620 nm Power Consumption 0.85 W 7820C CATV Optical Receiver 200 MHz HFC Return Path |
