Fast Ethernet 100BASE-LX10 SFP Single Mode Transceivers with Digital Diagnostics TRXAG1M Single Mode Product Description The TRXAG1M SFP series of multi-rate fiber optic transceivers with integrated digital diagnostics monitoring functionality provide a quick and reliable interface for 1000BASE-LX Gigabit Ethernet and 1.062GBd Fibre Channel applications. The transceivers are designed to support data rates ranging from 1.25Gb/s down to 125Mb/s. The diagnostic functions, alarm and warning features as described in the Multi-Source Agreement (MSA) document, SFF-8472 (Rev. 9.4), are provided via an I2C serial interface. Four options are offered with minimum optical link power budgets of 11, 18, 22 and 24dB to support 10km to 80km link applications. Option “LX” uses a 1310nm Fabry Perot laser and provides a minimum optical link budget of 11dB, corresponding to a minimum distance of 10km, assuming fiber loss of 0.45dB/km. Option “EX” uses a 1310nm DFB laser and provides a minimum optical link budget of 18dB, corresponding to a minimum distance of 40km, assuming fiber loss of 0.35dB/km. Options “YX” and “ZX” use 1550nm DFB lasers and provide a minimum optical link budgets of 22dB and 24dB respectively, which correspond to minimum distances of 72km and 80km, assuming fiber loss of 0.25dB/km. All modules satisfy Class I Laser Safety requirements in accordance with the U.S. FDA/CDRH and international IEC-60825 standards. The 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. LVTTL Transmitter Disable control input and Loss of Signal output interfaces are also provided. The transceivers operate from a single +3.3V power supply over three operating case temperature ranges of -5°C to +70°C, -25°C to +85°C, or -40°C to +85°C. The housing is made of plastic and metal for EMI immunity.

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. 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 and 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). Upon power Laser Safety: All transceivers are Class I Laser products per FDA/CDRH and IEC-60825 standards. They must be operated under specified operating conditions. Oplink Communications, Inc.

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. Assuming a total connector and splice loss of 2dB, total system penalty of 2dB and fiber cable loss of 0.35dB/km. Assuming a total connector and splice loss of 2dB, total system penalty of 2dB and fiber cable loss of 0.25dB/km.
