OPLINK TRPAG1VXI

Very Long Haul Gigabit Ethernet SFP
Transceivers with Digital Diagnostics
TRPAG1VXIxMS
Product Description
The TRPAG1VXIxMS SFP fiber optic transceivers with integrated digital diagnostics monitoring functionality offer a quick and reliable interface for Gigabit
Ethernet 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.
The transceivers use a high power 1550nm DFB laser and an ultra high sensitivity Avalanche Photodiode (APD) receiver to provide a minimum optical link
budget of 32dB, corresponding to a transmission distance of around 120km
of single mode fiber (assuming a total connector and splice loss of 2dB, total
system penalty of 3dB and fiber loss of 0.22dB/km). The transceivers satisfy
Class I Laser Safety requirements in accordance with the U.S. FDA/CDRH and
international IEC-60825 standards.
The TRPAG1VXIxMS 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.
Features
 Compatible with SFP MSA
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.
 Internal Calibration for Digital Diagnostics
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 (“B” option) or -5°C to +85°C (“E” option). The housing is made of metal to enhance EMI protection.

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
