| Very Long Haul Gigabit Ethernet SFP Transceivers with Digital Diagnostics TRPEG1KVX-E1 Product Description The TRPEG1KVX-E1 SFP fiber optic transceivers with integrated digital diagnostics monitoring functionality offer a quick and reliable interface for Gigabit Ethernet applications. 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. The transceivers use a high power 1550nm DFB laser and an ultra high sensitivity Avalanche Photodiode (APD) receiver to provide a minimum optical link budget of 32dB, corresponding to a transmission distance of around 120km of single mode fiber (assuming a total connector and splice loss of 2dB, total system penalty of 3dB and fiber loss of 0.22dB/km). The transceivers satisfy Class I Laser Safety requirements in accordance with the U.S. FDA/CDRH and international IEC-60825 standards. The TRPEG1KVX-E1 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 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 (Commercial) or -5C to +85C (Extended). The housing is made of metal to enhance EMI protection.

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 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 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. 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. 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. 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.

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. 2 Assuming a total connector and splice loss of 2dB, total system penalty of 3dB and fiber loss of 0.22dB/km.
