Single Fiber Bi-Directional Fast Ethernet SFP Single Mode

Single Fiber Bi-Directional Fast
Ethernet SFP Single Mode Transceivers
TRPBFELX
Product Description
The TRPBFELX modules are single fiber, bi-directional SFP transceivers that
provide a quick and reliable interface for 100BASE-BX10-D/U Fast Ethernet
applications.
Two types of modules are available: the 1310nm Fabry Perot laser-based
transceiver (BX10-U) and the 1550nm Fabry Perot laser-based transceiver
(BX10-D). All modules meet Class I Laser Safety requirements in accordance
with the U.S. and international standards as described in the FDA/CDRH and
IEC-60825 documents, respectively.
The TRPBFELX transceivers connect to standard 20-pad SFP connectors for
hot plug capability. This allows the system designer to make configuration or
maintenance changes by simply plugging in different types of transceivers
without removing the power supply from the host system.
The transceivers have color-coded latches that identify the TX wavelength.
The MSA compliant latch offers an easy and convenient way to release the
module.

Application Notes
Electrical Interface: All signal interfaces are compliant with
the SFP MSA specification. The high speed DATA interface
is differential AC-coupled internally 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.
Serial Identification: The module definition of SFP is indicated
by the three module definition pins, MOD_DEF(0), MOD_
DEF(1) and MOD_DEF(2). 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 negative edge
clocks data from the SFP EEPROM.
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.
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.
EEPROM ID is per SFF-8472, Rev. 9.4.
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.
TX Disable: When the TX Disable pin is at logic HIGH, the
transmitter optical output is disabled (less than -45dBm).
