FEATURES
DESCRIPTION
lSingle Fiber Bi-Directional Transceiver
l1550 nm DFB LD Transmitter
l1310 nm Receiver
The BTRS-3740 series is high performance module for
single fiber communications by using 1550 nm transmitter
and 1310 nm receiver. The transmitter section uses a
multiple quantum well laser and is a class 1 laser compliant
according to International Safety Standard IEC-60825. The
receiver section uses an integrated 1310 nm detector
preamplifier (IDP) mounted in an optical header and a
limiting post-amplifier IC. A PECL logic interface
simplifies interface to external circuitry.
