Very Long Haul Gigabit Ethernet SFP
Transceivers with Digital Diagnostics
TRPEG1KVX-E1
Product Description
The TRPEG1KVX-E1 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. 9.4), are provided via an I
2
C 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 TRPEG1KVX-E1 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 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 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 an
operating case temperature range of -5°C to +70°C (Commercial) or
-5°C to +85°C (Extended). 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 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.
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.
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).
TX Disable:
When the TX Disable pin is at logic HIGH, the
transmitter optical output is disabled (less than -45dBm).
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 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 I
2
C 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.
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.
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. 9.4.
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.

These are target distances to be used for classification and not for specification, per Telcordia GR-253-CORE/ITU-T Recommendation G.957.
The indicated transmission distance is for guidelines only, not guaranteed. The exact distance is dependent on the fiber loss, con-
nector and splice loss, and allocated system penalty. Longer distances can be supported if the optical link power budget is satisfied.
