Multi-rate OC-12/STM-4 SFP Transceivers with Digital Diagnostics TRPC12-E2G SM MULTI-RATE Pb Pro d u c t D e s c rip tio n The TRPC12-E2G SM SFP series of multi-rate fiber optic transceivers w ith integrated digital diagnostics monitoring functionality provide a quick and reliable interface for OC-12 short reach (SR), intermediate reach (IR) and long reach (LR) applications. The diagnostic functions, alarm and w arning features as described in the Multi-Source Agreement (MSA )document,SFF-8472 (Rev. 9.4),are provided via an I2C serial interface. Available products under this series are compliant w ith SON ET/ SD H standards for OC-12/STM-4 applications and are capable of operating dow n to 155Mb/s data rate. The SR-1 and IR-1 versions are compliant w ith OC-12/STM-4 and OC-3/STM-1 interface standards. A ll modules satisfy Class I Laser Safety requirements in accordance w ith the U .S. and international standards as described in the FD A /CD RH and IEC-60825 documents,respectively. The TRPE12-E2G SM multi-rate 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 shutting dow n the pow er supply of the host system. The transceivers have colored bail-type latch, w hich offer an easy and convenient w ay to release the modules. The latch is compliant w ith the SFP MSA . The transmitter design incorporates a highly reliable 1310nm or 1550nm InG aA sP laser and an integrated driver circuit. The receiver features a transimpedance amplifier IC optimized for high sensitivity and w ide dynamic range. The transmitter and receiver D ATA interfaces are AC-coupled internally. LVTTL 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 tw o operating case temperature ranges of -5°C to +70°C (Commercial)or -40°C to +85°C (Industrial). The housing is made of metal for EMI immunity.

The high speed D ATA interface is differential AC-coupled internally w ith 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. 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 of the 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 of TX 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 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 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, MOD _D EF(0),MOD _D EF(1)and MOD _D EF(2). U pon pow er up, MOD _D EF(1:2)appear as N C (no connection),and MOD _D EF(0) Oplink Communications, Inc. 4 S0114,Rev.01 2009-10-23 TR PC12-E 2G Single Mode Multi-rate Package O utline 41.80 9.20 [.362] 14.94 [.588] 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 8 6 4 0 7T 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.om [.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 1 Part N umber O perating Temperature Latch C olor N ominal W avelength SO N ET/SD H Standards D istance1 TRPC12A S1C000E2G - 5°C to +70°C G ray 1310nm SR-1/I-4 12/2km TRPC12A I1C000E2G - 5°C to +70°C Yellow 1310nm IR-1/S-4.1 21/15km TRPC12G L1C000E2G - 5°C to +70°C Red 1310nm LR-1/L-4.1 42/40km TRPC12G L2C000E2G - 5°C to +70°C W hite 1550nm LR-2/L-4.2 85/80km TRPC12A S1I000E2G - 40°C to +85°C G ray 1310nm SR-1/I-4 12/2km TRPC12A I1I000E2G - 40°C to +85°C Yellow 1310nm IR-1/S-4.1 21/15km TRPC12G L1I000E2G - 40°C to +85°C Red 1310nm LR-1/L-4.1 42/40km TRPC12G L2I000E2G - 40°C to +85°C W hite 1550nm LR-2/L-4.2 85/80km These are target distances to be used for classification and not for specification,per Telcordia G R-253-CORE/ITU -T Recommendation G .957.
