The BTRS-7920CG 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 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
APPLICATIONS

l SONET/SDH Equipment Interconnect
l Fiber Channel Links
specified temperature and voltage limits. The optical ports of
the module shall be terminated with an optical connector or
with a dust plug.
