The BTRS-7940CG series is high performance module for
single fiber communications by using 1490 nm transmitter
and 1310 nm receiver. The transmitter section uses a
multiple quantum well 1490 nm DFB laser and is a class 1
laser compliant according to International Safety Standard
IEC-60825. The receiver section is designed to receive 1310
nm and block 1490 nm signal. This feature is suitable for
IEEE 802.3ah 1000BASE-BX and ITU-T 983.3 application.
A PECL logic interface simplifies interface to external
circuitry. LVTTL 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.
