DESCRIPTION
18-Wavelength CWDM Transceivers
Duplex SC/ST/FC Single Mode Transceiver
Long-Reach SONET OC-3 / SDH STM-1Compliant
CWDM DFB LD Transmitter
34 dB Link Budget at Least
Industry Standard 1 x 9 Footprint
Single +5 V Power Supply
RoHS Compliant
PECL Signal Detection Output
LED Multisourced 1 x 9 Transceiver Interchangeable
Wave Solderable and Aqueous Washable
Class 1 Laser International Safety Standard IEC 825
Compliant
The TRS-32120-CXX0G series single mode transceivers is
low power, high performance CWDM modules for
bi-directional serial optical data communications such as
SONET OC-3 / SDH STM-1 and Fast Ethernet. There are
eighteen center wavelengths from 1270 nm to 1610 nm. A
guaranteed minimum optical link budget of 34 dB is
offered. The transmitter section uses a multiple quantum
well DFB 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.

***********************************************************************************************************************************************************************
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.
