The BTRS-77120C-1590G series is high performance
module for single fiber communications by using 1590 nm
transmitter and 1510 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 1590 nm DFB laser
and is a class 1 laser compliant according to International
Safety Standard IEC 60825. The receiver section uses an
integrated 1510 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.
