DESCRIPTION 
The BTRS-7700MG series is high performance module for 
multi-mode 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. LV-TTL 
Signal Detect is used. 
LASER SAFETY
This multi-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.
