Multi-rate Gigabit Ethernet & Fibre Channel SFP Transceivers with Digital DiaGnostics TRPEG1-E2 Single Mode Produ c t D es c rip tion The TRPEG 1-E2 SFP series of multi-rate fiber optic transceivers w ith integrated digital diagnostics monitoring functionality provide a quick and reliable interface for 1000BA SE-LX G igabit Ethernet and 1.062G Bd Fibre Channel applications. The transceivers are designed to support data rates ranging from 1.25G b/s dow n to 125M b/s. The diagnostic functions,alarm and w arning features as described in the M ulti-Source A greement (M SA ) document,SFF-8472 (Rev. 9.4),are provided via an I2C serial interface. Four options are offered w ith minimum optical link pow er budgets of11dB, 18dB,22dB 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 D FB laser and provides a minimum optical link budget of 18dB,corresponding to a minimum distance of40km,assuming fiber loss of0.35dB/km. Options “YX”and “ZX”use 1550nm D FB lasers and provide a minimum optical link budgets of 22dB and 24dB respectively,w hich correspond to minimum distances of 70km and 80km, assuming fiber loss of 0.25dB/km. A ll modules satisfy Class I Laser Safety requirements in accordance w ith the U .S. FD A /CD RH and international IEC-60825 standards. The transceivers connect to standard 20-pad SFP connectors for hot plug capability. This allow s the system designer to make configuration changes or maintenance by simply plugging in different types of transceivers w ithout removing the pow er supply from the host system. The transceivers have colored bail-type latches,w hich offer an easy and convenient w ay to release the modules. The latch is compliant w ith the SFP M SA . The transmitter and receiver D ATA interfaces are AC-coupled internally. LV-TTL Transmitter D isable control input and Loss of Signal output interfaces are also provided. The transceivers operate from a single +3.3V pow er supply over operating case temperature ranges of-5°C to +70°C or -40°C to +85°C. The housing is made ofmetal for EM I immunity.

The high speed D ATA interface is diff erential A C-coupled internally w ith 0.1µF and can be directly connected to a 3.3V SERD ES IC. A ll low speed control and sense output signals are open collector TTL compatible and should be pulled up w ith a 4.7 - 10kΩ resistor on the host board. up, M OD _D EF(1:2) appear as N C (no connection), and M OD _D EF(0) is TTL LOW . W hen the host system detects this condition,it activates the serial protocol (standard tw o-w ire 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 w rite protected,and the negative edge clocks data from the SFP. Loss of Signal (LOS): The Loss of Signal circuit monitors the level ofthe incoming optical signal and generates a logic H IG H w hen an insufficient photocurrent is produced. The serial data signal (SD A ) is for serial data transfer. The host uses SD A in conjunction w ith SCL to mark the start and end of serial protocol activation. The supported monitoring functions are temperature,voltage,bias current,transmitter pow er,average receiver signal,all alarms and w arnings,and softw are monitoring ofTX Fault/LOS. The device is internally calibrated. TX Fault: The output indicates LOW w hen the transmitter is operating normally,and H IG H w ith a laser fault including laser end-of-life. TX Fault is an open collector/drain output and should be pulled up w ith a 4.7 - 10kΩ resistor on the host board. TX Fault is non-latching (automatically deasserts w hen fault goes aw ay). The data transfer protocol and the details of the mandatory and vendor specific data structures are defined in the SFP M SA , and SFF-8472,Rev. 9.4. TX Disable: W hen the TX D isable pin is at logic H IG H , the transmitter optical output is disabled (less than -45dBm). Power Supply and Grounding: The pow er supply line should be w ell-filtered. A ll 0.1μF pow er 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, M OD _D EF(0), M OD _D EF(1) and M OD _D EF(2).
