DESCRIPTION 
The BTRS-9780-1510G series is high performance module 
for single fiber communications by using 1510 nm 
transmitter and 1590 nm receiver. The transmitter  section  
uses  a  multiple  quantum well 1510 nm DFB  laser  and is a 
class 1 laser compliant according to International Safety 
Standard IEC 60825. The receiver section uses an integrated 
1590 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.
