The TRS-73180G 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 38 dB is
offered which can correspond to a link distance of over 180
km (assuming worst case fiber loss of 0.20 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.

The split-load terminations for ECL signals need to be located at the input of devices receiving those ECL signals. The
power supply filtering is required for good EMI performance. Use short tracks from the inductor L1/L2 to the module
Rx Vcc and Tx Vcc. A GND plane under the module is required for good EMI and sensitivity performance.
