Compliant
The BTRS-77120C-1510G series is high performance
module for single fiber communications by using 1510 nm
transmitter and 1590 nm receiver. A guaranteed minimum
optical link budget of 31 dB is offered which can correspond
to a link distance of over 120 km (assuming worst case fiber
loss of 0.22 dB/km). 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. Signal Detect with
LC-TTL 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.
