Extended Reach Multi-rate OC-48/STM-16 LR-2/L-16.2
SFP CWDM Transceivers with Digital Diagnostics
TRPE48KE2 CWDM
Product Description
The TRPE48KE2 CWDM 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 Fiber Channel 200-SMLC-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 and are available in eight (8) wavelengths: 1471nm,
1491nm, 1511nm, 1531nm, 1551nm, 1571nm, 1591nm and 1611nm.
The higher optical link power budget of 32dB is to accommodate
the wavelength multiplexing and de-multiplexing insertion losses.
All transceivers are Class I Laser products per U.S. FDA/CDRH and
international IEC-60825 standards.
The TRPE48KE2 CWDM 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
(LOS) 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
Temp.) or -5°C to +85°C (Extended Temp.). 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 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. When 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 insufficient photocurrent is produced.
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.
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
that should be pulled up with a 4.7 - 10kΩ resistor on the
host board. TX Fault in 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: When 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).

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.
