The TRPEG 1KVX-E1G SFP fiber optic transceivers with integrated digital
diagnostics monitoring functionality offer a quick and reliable interface
for G igabit Ethernet applications. The diagnostic functions,alarm and
warning features as described in the Multi-Source A greement (MSA )
document,SFF-8472 (Rev. 9.4),are provided via an I
2
C serial interface.
The transceivers use a high power 1550nm D FB laser and an ultra high
sensitivity Avalanche Photodiode (A PD ) 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. FD A /CD RH and international IEC-60825
standards.
The TRPEG 1KVX-E1G 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 D ATA interfaces are AC coupled internally.
LV-TTL Transmitter D isable 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.

Electrical Interface:
A ll signal interfaces are compliant with
the SFP MSA specification. The high speed D ATA interface is
differential AC-coupled internally with 1 F and can be directly
connected to a 3.3V SERD ES IC. A ll low speed control and sense
output signals are open collector TTL compatible and should
be pulled up with a 4.7 - 10k 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 H IG H
when an insufficient photocurrent is produced.
TX Fault:
The output indicates LOW when the transmitter
is operating normally,and H IG H 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 - 10k resistor on the host
board. TX Fault is non-latching (automatically deasserts when
fault goes away).
TX Disable:
W hen the TX D isable pin is at logic H IG H , 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 _D EF(0),MOD _D EF(1) and MOD _D EF(2). U pon power up,
MOD _D EF(1: appear as N C (no connection),and MOD _D EF(0)
2)
is TTL LOW . W hen 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 (SD A ) is for serial data transfer. The
host uses SD A in conj
unction 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. A ll 0.1 F power supply bypass capacitors
should be as close to the transceiver module as possible.
