FEATURES
DESCRIPTION
l Single Fiber Bi-Directional SFF Transceiver
l 1310 nm Transmitter
The BTRS-7620CG series is high performance module for
single fiber communications by using 1310 nm transmitter
and 1550 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 1550 nm detector
preamplifier (IDP) mounted in an optical header and a
limiting post-amplifier IC. A PECL logic interface
simplifies interface to external circuitry. LV-TTL Signal
Detect is used.
