Three types of modules are available: the 1310nm Fabry Perot laser-based transceiver (BX10-U), and the 1490nm or 1550nm DFB laser-based transceivers (BX10-D). The transceivers are designed to support data rates ranging from 1250Mb/s down to 125Mb/s and are integrated with digital diagnostics monitoring, which provides features to detect a problem before system performance is impacted. The diagnostic functions, alarms and warning features are provided via an I2C serial interface as described per the Multi-Source Agreement (MSA) document, SFF-8472 (Rev. 9.4). described in the FDA/CDRH and IEC-60825 documents, respectively. The TRXBG1LXM 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. All modules meet Class I Laser Safety requirements in accordance with the U.S. and international standards as The transceivers operate from a single +3.3V power supply over an operating case temperature range of -5°C to +70°C or -40°C to +85°C. The package is made of metal. 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 ACcoupled internally. LV-TTL Transmitter Disable control input and Loss of Signal output interfaces are also provided.

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. 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. This device does not require clock stretching. 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 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). TX Disable: When the TX Disable pin is at logic HIGH, the transmitter optical output is disabled (less than -45dBm). 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. 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). 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. 4 21737-0929, Rev.
