DESCRIPTION
The TRS-73120G series single mode transceivers is low
power, high performance module for bi-directional serial
optical data communications such Gigabit Ethernet and
Fibre Channel. This module is designed for single mode
fiber and operates at a nominal wavelength of 1550 nm. A
guaranteed minimum optical link budget of 32 dB is offered
which can correspond to a link distance of over 120 km
(assuming worst case fiber loss of 0.25 dB/km). 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 uses an
integrated InGaAs Avalanche photodetector 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.
