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 broadband 7810 video receiver module is a versatile,
state-of-the-art solution for a variety of network applications.
Features
s
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.
Wide 40 MHz—1000 MHz bandwidth supports as
many as 110 CATV analog channels or a combina-
tion of analog/digital channels (e.g., 80/30), includ-
ing 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
Ω)
Robust, small package with single-mode fiber pig-
tail and connector options
Wide operating temperature range, –40
°C
to
+85

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
