DESCRIPTION 
The BTR-7810G 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 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.
