Description

The 7810 video 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 combination of analog and digital channels (80/30, for example), including HDTV broadcast.

The 7810 exhibits excellent distortion performance with values well above standards over the entire bandwidth and temperature specifications (40 MHz—1000 MHz, –40 °C to +85 °C).

Moreover, the advanced impedance-match circuitry between the photodetector and RF amplification stages resolves a number of OEM design obstacles with very low typical noise performance value, not exceeding 4.5 pA/√Hz.

The 7810 video receiver can be used in both 1310 nm and 1550 applications, being useful at different points of a given network.

Features

■ Wide 40 MHz—1000 MHz bandwidth supports as

many as 110 CATV analog channels or a combination of

analog/digital channels (e.g., 80/30), including HDTV broadcast

■ Excellent frequency and distortion characteristics for high linearity

■ Low noise (4.5 pA/√Hz, typ.), low power dissipation

(1.35 W max.), as well as high RF output

■ Internal impedance-match circuitry (75 ?)

■ Robust, small package with single-mode fiber pigtail and connector options

■ Wide operating temperature range, –40 °C to +85 °C

Applications

■ Video signal distribution in HFC and FTTx nodes

■ Video overlay in passive optical networks (PON)
