DESCRIPTION 
The BTRS-7810CG series is high performance module for 
single fiber communications by using 1310 nm transmitter 
and 1490 nm receiver. 
This module is equipped with 
3W-TRX
TM
 OE device to reject 1.55 um high power 
video signal. 
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 is designed to receive 1490 nm and block 
1550 nm signal. This feature is suitable for   IEEE 802.3ah 
1000BASE-BX10 and ITU-T 983.3 application. The 
receiver section uses an integrated 1490 nm detector 
preamplifier (IDP) mounted in an optical header and a 
limiting post-amplifier IC. A PECL logic interface 
simplifies interface to external circuitry. 
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.
