The TRS-72120G 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 0.22 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 detector preamplifier (IDP) mounted in
an optical header and a limiting post-amplifier IC. A PECL
logic interface simplifies interface to external circuitry.

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.
