Description
The 7810 video receiver is a single-mode fiber pig-
tailed module featuring a low-noise, impedance-
matched broadband photodiode and RF amplifica-
tion.
The device receives optical analog and/or digital sig-
nals 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.
