SQOB1223 1.2GHz Optical Receiver Block

Model Number: SQOB1223 Brand Name: SQ Key Specifications/Special Features: SQOB1223 Optical ReceiverBlockis asingle-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 channels or a combination of analog and digital channels (80/30 for example), including HDTV broadcast.The device exhibits excellent distortion performance with values well above standards over the entire bandwidth and case temperature specifications (47 to1218 MHz, - 30to +85 °C).Moreover, the proprietary impedance-match circuitry between the photo detector and RF amplification stages provides a very low noise performance value, typically less than 4.5 pA/√Hz.The device can be used in both 1310 nm and 1550 nm applications being useful at different points of a given network.Featuresl47 to 1218 MHz bandwidth supports as many as 110 CATV analog channels or a combination of analog and digital channels including HDTV broadcast.lExcellent RF Frequency and distortion characteristics for high linearity.lLow noise (4.5 pA/√Hz typ.) and low power dissipation (0.75 W max.) as well as high RF output.lInternal proprietary impedance match circuitry (75)lRobust small package with single-mode fiber pigtail and connector options
lWide operating case temp range, - 30 to + 85°C

Applications
lVideo signal distribution in HFC and FTTx nodes
