OPLINK TRPA12MM

OC-12/STM-4 SFP Multimode
Transceivers with Digital Diagnostics
TRPA12MM
Product Description
The TRPA12MM SFP fiber optic transceivers with integrated digital diagnostics monitoring functionality provide a quick and reliable interface for
OC-12/STM-4 multimode applications. The diagnostic monitoring functions, alarm and warning features are provided via an I2C serial interface.
The transceivers are designed to be compatible with the ATM requirements at OC-12/STM-4 (622Mb/s) data rate.
The TRPA12MM 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 removing the power supply from the host system.
The transmitter design incorporates a highly reliable 1310nm LED and an
integrated driver circuit. The receiver features a transimpedance amplifier
IC for high sensitivity and wide dynamic range. The transmitter and receiver DATA interfaces are AC-coupled internally. LV-TTL Transmitter Disable control input and Loss of Signal output interfaces are also provided.
The transceivers operate from a single +3.3V power supply over three
operating case temperature ranges of -5°C to +70°C (“B” option), -5°C to
+85°C (“E” option), or -40°C to +85°C (“A” option). The housing is made of
plastic and metal for EMI enhancement.

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.
MOD_DEF(0), MOD_DEF(1) and MOD_DEF(2). Upon power
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 RPM (receiver power monitor), internal temperature and
module supply voltage. The device is internally calibrated.
TX Fault: Per SFP MSA, pin 2 is TX Fault. This transceiver is
LED based and does not support TX Fault. Pin 2 is internally
connected to transmitter circuit ground (TX GND) to indicate
normal operation.
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,
