OPLINK TRPA12MSM

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 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. 9.3), 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 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 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.

Application Notes
Electrical Interface: All signal interfaces are compliant with
the SFP MSA specification. The high speed DATA interface
is differential AC-coupled internally with 0.1μF and can be
directly connected to a 3.3V SERDES IC. All low speed control
and sense output signals are open collector TTL compatible
and should be pulled up with a 4.7 - 10kΩ resistor on the host
board.
up, MOD_DEF(1:2) appear as NC (no connection), and
MOD_DEF(0) is TTL LOW. When the host system detects this
condition, it activates the serial protocol (standard two-wire
I2C serial interface) and generates the serial clock signal (SCL).
The positive edge clocks data into the EEPROM segments of
the SFP that are not write protected and the negative edge
clocks data from the SFP.
Loss of Signal (LOS): The Loss of Signal circuit monitors the
level of the incoming optical signal and generates a logic HIGH
when an insufficient photocurrent is produced.
The serial data signal (SDA) is for serial data transfer. The
host uses SDA in conjunction with SCL to mark the start and
end of serial protocol activation. The supported monitoring
functions are temperature, voltage, bias current, transmitter
power, average receiver signal, all alarms and warnings, and
software monitoring of TX Fault/LOS. The device is internally
calibrated.
TX Fault: The output indicates LOW when the transmitter
is operating normally, and HIGH with a laser fault including
laser end-of-life. TX Fault is an open collector/drain output
and should be pulled up with a 4.7 - 10kΩ resistor on the host
board. TX Fault is non-latching (automatically deasserts when
fault goes away).
The data transfer protocol and the details of the mandatory
and vendor specific data structures are defined in the SFP MSA
and SFF-8472, Rev. 9.3.
TX Disable: When the TX Disable pin is at logic HIGH, the
transmitter optical output is disabled (less than -45dBm).
Power Supply and Grounding: The power supply line should
be well-filtered. All 0.1μF power supply bypass capacitors
should be as close to the transceiver module as possible.
Serial Identification and Monitoring: The module definition
of SFP is indicated by the three module definition pins,
MOD_DEF(0), MOD_DEF(1) and MOD_DEF(2). Upon power
