DESCRIPTION

The TRS-7120G 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 1310 nm. The

transmitter section uses a multiple quantum well laser

and is a class 1 laser compliant according to International

Safety Standard IEC-825. 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.

LASER SAFETY

This single mode transceiver is a Class 1 laser product. It

complies with IEC 825 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.
