TRPE48KE2C000E2

Extended Reach Multi-rate OC-48/STM-16 LR-2/L-16.2
SFP Transceivers with Digital Diagnostics
TRPE48KE2-E2 Multi-rate
Pro d uc t D es c rip tio n
The TRPE48KE2-E2 SFP series of multi-rate fiber optic transceivers
with digital diagnostics monitoring functionality provide a quick
and reliable interface for extended reach (LR-2) applications.
Diagnostics monitoring functionality (alarm and warning
features) is integrated into the design via an I2C serial interface
per the Multi-Source Agreement (MSA) SFF-8472, Rev. 9.4.
Products under this series are compatible with SONET/SDH
standards for OC-48/STM-16 (2.488Gb/s) LR-2/L-16.2 extended
reach applications, OC-3/STM-1 (156Mb/s) and OC-12/STM-4
(622Mb/s) SR/I-1 and I-4 short reach applications; Gigabit Ethernet
LX (1.25Gb/s) applications per IEEE 802.3; and Fibre Channel 200SM-LC-L (2.125Gb/s) and 100-SM-LC-L (1.062Gb/s) applications
per FC-PI standards. The transceivers support data rates ranging
from 2.67Gb/s down to 125Mb/s. All modules satisfy Class I Laser
Safety requirements in accordance with the U.S. FDA/CDRH and
international IEC-60825 standards.
The TRPE48KE2-E2 multi-rate 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 range of -5°C to +70°C (Commercial)
or -5°C to +85°C (Extended). The housing is made of metal for
EMI immunity.

A pplication N otes
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
Upon power up, MOD_DEF(1:2) appear as NC (no connection),
and MOD_DEF(0) is TTL LOW . W hen the host system detects
this condition, it activates the serial protocol (standard
two-wire 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 write 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
HIGH when an insuffi cient photocurrent is produced.
The serial data signal (SDA) is for serial data transfer. The
host uses SDA in conjunction with SCL to mark the startand
end of serial protocol activation. The supported monitoring
functions are internal temperature, supply voltage, bias
current, transmitter power, average receiver signal, all alarms
and warnings and software monitoring of TX Fault/LOS. The
device is internally calibrated.
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).
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 Disable pin is at logic HIGH, the
transmitter optical output is disabled (less than -45dBm).
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.
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).
