FEATURES
DESCRIPTION
l Duplex SC Single Mode Transceiver: TRS-7250G
l Duplex ST Single Mode Transceiver: TRS-7250TG
l Duplex FC Single Mode Transceiver: TRS-7250FG
l Compliant with IEEE-802.3z Gigabit Ethernet
l 1550 DFB LD Transmitter
The TRS-7250G 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 19 dB is offered
which can correspond to a link distance of over 50 km
(assuming worst case fiber loss of 0.3 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.
