FEATURES
DESCRIPTION
l Single Fiber SFF Bi-Directional Transceiver
l 1550 nm Transmitter
The BTRS-3720G 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.
l 1310 nm Receiver
l Distance Up to 20 km
l Single +3.3 V Power Supply
l RoHS Compliant
l PECL Differential Inputs and Outputs
l 0 to 70oC Operating Temperature: BTRS-3720G
l -20 to 85oC Operating Temperature: BTRS-3720AG
l Wave Solderable and Aqueous Washable
l Class 1 Laser International Safety Standard IEC-60825
Compliant
LASER SAFETY
This single mode transceiver is a Class 1 laser product. It
complies with IEC-60825 and FDA 21 CFR 1040.10 and
1040.11. The transceiver must be operated within the
specified temperature and voltage limits. The optical ports
of the module shall be terminated with an optical connector
or with a dust plug.
