Pro d u c t D e s c rip tio n
The TRPC12-E2G SM SFP series of multi-rate fiber optic transceivers
w ith integrated digital diagnostics monitoring functionality
provide a quick and reliable interface for OC-12 short reach (SR),
intermediate reach (IR) and long reach (LR) applications. The
diagnostic functions, alarm and w arning features as described
in the Multi-Source Agreement (MSA )document,SFF-8472 (Rev.
9.4),are provided via an I2C serial interface.
Available products under this series are compliant w ith SON ET/
SD H standards for OC-12/STM-4 applications and are capable of
operating dow n to 155Mb/s data rate. The SR-1 and IR-1 versions
are compliant w ith OC-12/STM-4 and OC-3/STM-1 interface
standards. A ll modules satisfy Class I Laser Safety requirements in
accordance w ith the U .S. and international standards as described
in the FD A /CD RH and IEC-60825 documents,respectively.
The TRPE12-E2G SM multi-rate transceivers connect to standard
20-pad SFP connectors for hot plug capability. This allow s the
system designer to make configuration changes or maintenance
by simply plugging in different types of transceivers w ithout
shutting dow n the pow er supply of the host system.
The transceivers have colored bail-type latch, w hich offer an
easy and convenient w ay to release the modules. The latch is
compliant w ith the SFP MSA .
The transmitter design incorporates a highly reliable 1310nm
or 1550nm InG aA sP laser and an integrated driver circuit. The
receiver features a transimpedance amplifier IC optimized
for high sensitivity and w ide dynamic range. The transmitter
and receiver D ATA interfaces are AC-coupled internally. LVTTL
Transmitter D isable control input and Loss of Signal output
interfaces are also provided.
The transceivers operate from a single +3.3V pow er supply
over tw o operating case temperature ranges of -5°C to +70°C
(Commercial)or -40°C to +85°C (Industrial). The housing is made
of metal for EMI immunity.

Electrical Interface: A ll signal interfaces are compliant w ith
the SFP MSA specification. The high speed D ATA interface is
differential AC-coupled internally w ith 1μF 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 w ith a 4.7 - 10kΩ resistor on the host board.
is TTL LOW . W hen the host system detects this condition,
it activates the serial protocol (standard tw o-w ire 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 w rite 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 H IG H
w hen an insufficient photocurrent is produced.
The serial data signal (SD A ) is for serial data transfer. The
host uses SD A in conjunction w ith SCL to mark the start and
end of serial protocol activation. The supported monitoring
functions are temperature,voltage,bias current,transmitter
pow er,average receiver signal,all alarms and w arnings,and
softw are monitoring of TX Fault/LOS. The device is internally
calibrated.
TX Fault: The output indicates LOW w hen the transmitter
is operating normally,and H IG H w ith a laser fault including
laser end-of-life. TX Fault is an open collector/drain output
and should be pulled up w ith a 4.7 - 10kΩ resistor on the host
board. TX Fault is non-latching (automatically deasserts w hen
fault goes aw ay).
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.
TX Disable: W hen the TX D isable pin is at logic H IG H , the
transmitter optical output is disabled (less than -45dBm).
Power Supply and Grounding: The pow er supply line should
be w ell-filtered. A ll 0.1μF pow er 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 _D EF(0),MOD _D EF(1)and MOD _D EF(2). U pon pow er up,
MOD _D EF(1:2)appear as N C (no connection),and MOD _D EF(0)
