DESCRIPTION 
The BTRS-9605G 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 1310 nm 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. 
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.
