Very Long Haul Gigabit Ethernet SFP Transceivers with Digital Diagnostics Pb TRPEG1KVX-E1G Pro d u c t D e s c rip tio n The TRPEG 1KVX-E1G SFP fiber optic transceivers with integrated digital diagnostics monitoring functionality offer a quick and reliable interface for G igabit Ethernet applications. The diagnostic functions,alarm and warning features as described in the Multi-Source A greement (MSA ) document,SFF-8472 (Rev. 9.4),are provided via an I2C serial interface. The transceivers use a high power 1550nm D FB laser and an ultra high sensitivity Avalanche Photodiode (A PD ) 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. FD A /CD RH and international IEC-60825 standards. The TRPEG 1KVX-E1G 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 high speed D ATA interface is differential AC-coupled internally with 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 with a 4.7 - 10kΩ resistor on the host board. is TTL LOW . W hen 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 H IG H when an insufficient photocurrent is produced. The serial data signal (SD A ) is for serial data transfer. The host uses SD A 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 H IG H 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). 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: 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 power supply line should be well-filtered. A ll 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 _D EF(0),MOD _D EF(1) and MOD _D EF(2). U pon power up, MOD _D EF(1:2) appear as N C (no connection),and MOD _D EF(0) Oplink Communications, Inc. 4 S0150,Rev.01 2009-07-20 TR PEG1 K VX -E1 G Package O utline 41.80 9.20 [.362] [.588] 14.94 13.62 [.536] [1.646] 45.00 [1.772] [.257] 1.99 [.078] 6.25 0.60 [.024] 6.54 8.46 [.411] 10.45 [.333] [.470] 11.94 4 6 3 3 5L and ingP kwyF r e mont, CA9 4 5 3 8T e l: ( 5 1 0 )9 3 3 7 2 0 0F ax : ( 5 1 0 )9 3 3 7 3 0 0E mail: S ale [email protected] •www.oplink.com [.246] 2.29 [.090] 13.80 [.543] 1.49 [.059] 2.50 [.098] 0.60 [.024] 0.45 [.018] D imensions in inches [mm] D efault tolerances: .xxx = ± .005”,.xx = ± .01” O rdering Information Part N umber O perating Temperature TRPEG 1KVXC000E1G - 5°C to +70°C TRPEG 1KVXE000E1G - 5°C to +85°C Latch C olor N ominal W avelength O ptical Link Pow er B udget D istance1 Magenta 1550nm 32dBm min. 120km2 These are target distances to be used for classification and not for specification,per Telcordia G R-253-CORE/ITU -T Recommendation G .957.
