The TRS-7140G 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.
APPLICATIONS
l Switch to Switch Interface l High Speed Interface for File Servers l High Performance Desktops

For TTL SD Level, R1=R2=N.C., R7=100 ohm For PECL SD Level, R1=130 ohm, R2=82 ohm, R7=100 ohm 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.
