The TRPE12-E2 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 ( ,intermediate reach (
SR)
IR)
and long reach ( applications. The diagnostic functions, alarm and
LR)
w arning features as described in the Multi-Source Agreement (
MSA )
2
document,SFF-8472 (
Rev. 9.4) are provided via an I C serial interface.
,
Available products under this series are compliant w ith SONET/SDH
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 FDA /CDRH and IEC-60825
documents,respectively.
The TRPE12-E2 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 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 pow er supply over tw o
operating case temperature ranges of -5°C to +70°C (
COM) or -40°C to
+85°C (
IND) 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 DATA interface is
differential AC-coupled internally w ith 1 F and can be directly
connected to a 3.3V SERDES 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 - 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
w hen an insufficient photocurrent is produced.
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 - 10k resistor on the host
automatically deasserts w hen
board. TX Fault is non-latching (
fault goes aw ay)
.
TX Disable:
W hen the TX Disable 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_DEF( ,MOD_DEF( and MOD_DEF( . U pon pow er up,
0)
1)
2)
MOD_DEF( 2)appear as NC ( connection) and MOD_DEF(

,
0)
is TTL LOW . W hen the host system detects this condition,
it activates the serial protocol (
standard tw o-w ire 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 w rite 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 conj
unction 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.
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 pow er supply line should
be w ell-filtered. A ll 0.1 F pow er supply bypass capacitors
should be as close to the transceiver module as possible.
