Product specification

Optical receiver modules

BGO847; BGO847/FC0;

BGO847/SC0

FEATURES

• Improved BGE847BO

• Excellent linearity

• Extremely low noise up to 870 MHz

• Excellent flatness (straight line)

• Standard CATV outline

• Rugged construction

• Gold metallization ensures

excellent reliability

• High optical input power range.

APPLICATIONS

• CATV optical node systems

operating in the 40 to 870 MHz

frequency range.

DESCRIPTION

High dynamic range optical receiver

amplifier modules in a standard

SOT115 package where the

non-jacketed fibre has either no

connector or an FC/APC or an

SC/APC connector.

The amplifier supply voltage pin and

the photo diode bias voltage pin both

connect to 24 V (DC).

The modules have a monomode

optical input suitable for

1290 to 1600 nm wavelengths, a

terminal to monitor the photo diode

current and an electrical output

having a characteristic impedance of

75

Ω.
