Optical receiver module BGE847BO/FC

FEATURES

• Excellent linearity

• Extremely low noise

• Excellent flatness

• Standard CATV outline

• Rugged construction

• Gold metallization ensures excellent reliability

• FC/APC connector (JDS version).

APPLICATIONS

• CATV systems operating in the 40 to 860 MHz
frequency range.

DESCRIPTION

Hybrid high dynamic range optical receiver module in a
SOT115W package. Two of the module pins are for
connection to 24 V (DC); one for amplifier supply voltage
and the other for the pin diode bias.
The module contains a monomode optical input suitable
for wavelengths from 1290 to 1600 nm, a terminal to
monitor the pin diode current and an electrical output with
an impedance of 75 Ω. The optical fibre is terminated by
an FC/APC connector (JDS version) and partly reinforced
by a 3 mm diameter Kevlar buffer.

Notes

1. Two laser test; each laser with 40 % modulation index:
fp= 135 MHz; Pp= 0.5 mW;
fq= 189.25 MHz; Pq= 0.5 mW;
measured at fp+fq= 324.25 MHz.

2. Three laser test; each laser with 40 % modulation
index:
fp= 326.25 MHz; Pp= 0.33 mW;
fq= 333.25 MHz; Pq= 0.33 mW;
fr= 335.25 MHz; Pr= 0.33 mW;
measured at fp+fq−fr= 324.25 MHz.

3. The module normally operates at VB= 24 V, but is
able to withstand supply transients up to 30 V.
