Multi-Rate OC-12/STM-4 SFP Transceivers with Digital Diagnostics TRPU12xxxx000E2G Pb Product Description The TRPC12-E2G SM SFP series of multi-rate fiber optic transceivers with 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 warning 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 with SONET/SDH standards for OC-12/STM-4 applications and are capable of operating down to 155Mb/s data rate. The SR-1 and IR-1 versions are compliant with OC-12/STM-4 and OC-3/STM-1 interface standards. All modules satisfy Class 1 Laser Safety requirements in accordance with the U.S. and international standards as described in the FDA/CDRH and IEC-60825 documents, respectively. The TRPC12-E2G multi-rate 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 shutting down the power supply from the host system. Features Compliant with SONET/SDH OC-12/STM-4(622Mb/s) Compliant with SONET/SDH OC-3/STM-1(155Mb/s) Compliant with SFP MSA SONET/SDH Reaches (SR-1,IR-1,LR-1 & LR-2) 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. Digital Diagnostics through Serial Interface The transmitter design incorporates a highly reliable 1310nm or 1550nm InGaAsP laser and an integrated driver circuit. The receiver features a transimpedance amplifier IC optimized for high sensitivity and wide dynamic range. The transmitter and receiver DATA interfaces are ACcoupled internally. LVTTL Transmitter Disable control input and Loss of Signal output interfaces are also provided. Duplex LC Optical Interface The transceivers operate from a single +3.3V power supply over operating case temperature ranges of -5°C to +70°C (COM), -40°C to +85°C (IND) or -5°C to +85°C (EXT). The housing is made of metal for EMI immunity.

The high speed DATA interface is differential AC-coupled internally with 0.1µF 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. 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. 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 startand end of serial protocol activation. The supported monitoring functions are internal temperature, supply 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 that 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 SFPMSA, 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 Oplink Communications, Inc 4 S0442, Rev.01.
