FEATURES
DESCRIPTION
l Single Fiber SFF Transceiver
l 1310 nm Transmitter
The BTRS-3820G series is high performance module for
single fiber communications by using 1310 nm transmitter
and 1490 nm receiver. This module is equipped with
3W-TRXTM OE device to reject 1.55 um high power
video signal. The transmitter section uses a multiple
quantum well 1310 nm laser and is a class 1 laser compliant
according to International Safety Standard IEC-825. The
receiver section uses an integrated 1490 nm detector
preamplifier (IDP) mounted in an optical header and a
limiting post-amplifier IC. A LVPECL logic interface
simplifies interface to external circuitry.
