Multi-rate Gigabit Ethernet & Fibre Channel
SFP Transceivers with Digital Diagnostics
TRPEG1-E2G Single Mode
Pb
Product Description
The TRPEG1-E2G SFP series of multi-rate fiber optic transceivers
with integrated digital diagnostics monitoring functionality provide
a quick and reliable interface for Gigabit Ethernet and 1.062GBd
Fibre Channel applications. The transceivers are designed to
support data rates ranging from 1.25Gb/s down to 125Mb/s. 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.
Four options are offered with minimum optical link power budgets
of 18dB, 22dB and 24dB to support up to 80km link applications.
Option “EX” uses a 1310nm DFB laser and provides a minimum
optical link budget of 18dB, corresponding to a minimum distance
of 40km, assuming fiber loss of 0.35dB/km. Options “YX” and “ZX”
use 1550nm DFB lasers and provide a minimum optical link budgets
of 22dB and 24dB respectively, which correspond to minimum
distances of 70km and 80km, assuming fiber loss of 0.25dB/km. All
modules satisfy Class I Laser Safety requirements in accordance with
the U.S. FDA/CDRH and international IEC-60825 standards.
The 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
operating case temperature ranges of -5°C to +70°C or -40°C to
+85°C. The housing is made of metal for EMI immunity.

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.
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.
Laser Safety
Laser Safety:
All transceivers are Class I Laser products per
FDA/CDRH and IEC-60825 standards. They must be operated
under specified operating conditions.
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.

The indicated transmission distance is for guidelines only, not guaranteed. The exact distance is dependent on the fiber loss, connector and
splice loss, and allocated system penalty. Longer distances can be supported if the optical link power budget is satisfied.
