Multi-rate OC-12/STM-4 SFP
Transceivers with Digital Diagnostics
TRPA12M SM
Product Description
The TRPA12M SFP series of multi-rate fiber optic transceivers with inte-
grated 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. 9.3), are provided via an I²C serial interface.
Available products under this series are compliant with SONET/SDH stan-
dards 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, re-
spectively.
The TRPA12M 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 dif-
ferent 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 an integrated driver circuit. The receiver features a tran-
simpedance amplifier IC optimized for high sensitivity and wide dynamic
range. The transmitter and receiver DATA interfaces are AC-coupled inter-
nally. 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 two oper-
ating case temperature ranges of -5°C to +70°C and -40°C to +85°C.
