| OCP TRPBFELX Single Fiber Bi-Directional Fast Ethernet SFP Single Mode Transceivers Features Compatible with SFP MSA Compliant with IEEE 802.3ah Draft 3.3 Fast Ethernet 100BASE-BX10 PMD Specifications 1310nm and 1550nm Wavelengths Distances up to 10km over Single Mode Fiber -40C to +85C Operating Temperature Range Option Eye Safe (Class I Laser Safety) Duplex LC Optical Interface Hot-pluggable TX Fault & Loss of Signal Outputs TX Disable Input Single +3.3V Power Supply 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. 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 an operating case temperature range of -5C to +70C ("B" option) or -40C to +85C ("A" option). The package is made of metal.

The high speed DATA interface is differential AC-coupled internally with 1F 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 - 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 HIGH when an insufficient photocurrent is produced. 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 - 10k resistor on the host board. TX Fault is non-latching (automatically deasserts when fault goes away). TX Disable: When the TX Disable pin is at logic HIGH, the transmitter optical output is disabled (less than -45dBm). 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. 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 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 0.1F power supply bypass capacitors should be as close to the transceiver module as possible. 4 21737-0911, Rev.
