Compliant
The BTR-77120-1510G 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.
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.
