Multi-rate OC-12/STM-4 SFP Transceivers with
Digital Diagnostics
TRXA12M SM
Product Description
The TRXA12M SFP series of multi-rate fiber optic transceivers with integrated
digital diagnostics monitoring functionality provide a quick and reliable
interface for OC-12 short reach (SR), intermediate reach (IR) and long reach
(LR) applications. The diagnostic functions, alarm and warning features as
described in the Multi-Source Agreement (MSA) document, SFF-8472 (Rev.
9.4), are provided via an I²C serial interface.
Available products under this series are compliant with SONET/SDH
standards for OC-12/STM-4 applications and are capable of operating down
to 155Mb/s data rate. The SR-1 and IR-1 versions are compliant with OC-12/
STM-4 and OC-3/STM-1 interface standards. All modules satisfy Class I Laser
Safety requirements in accordance with the U.S. and international standards
as described in the FDA/CDRH and IEC-60825 documents, respectively.
The TRXA12M multi-rate transceivers connect to standard 20-pad SFP
connectors for hot plug capability. This allows the system designer to make
configuration changes or maintenance by simply plugging in different types
of transceivers without shutting down the power supply of the host system.
The transceivers have colored bail-type latches, which offer an easy and
convenient way to release the modules. The latch is compliant with the SFP
MSA
The transmitter design incorporates a highly reliable 1310nm or 1550nm
InGaAsP laser and a driver circuit. The receiver features a transimpedance
amplifier IC optimized for high sensitivity and wide dynamic range. The
transmitter and receiver DATA interfaces are AC-coupled internally. LVTTL
Transmitter Disable control input and Loss of Signal output interfaces are also
provided.
The transceivers operate from a single +3.3V power supply over an operating
case temperature range of -5°C to +70°C or -40°C to +85°C. The housing is
made of plastic and metal for EMI immunity.
