OC-3 1510nm Optical Supervisory Channel SFP Transceiver TRCE03KE2C000C3 Product Description The TRCE03KE2C000C3 SFP fiber optic transceiver with integrated digital diagnostics monitoring functionality provides a quick and reliable interface for optical supervisory channel 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 TRCE03KE2C000C3 transceiver uses a 1510nm DFB laser and an APD receiver to provide an optical link power budget of 44dB. The transceiver satisfies Class I Laser Safety requirements in accordance with the U.S. FDA/CDRH and international IEC-60825 standards. The transceiver connects to a standard 20-pad connector 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. Features 1510nm DFB Transmitter and APD Receiver The transceiver has a blue bail-type latch, which offers an easy and convenient way to release the module. The latch is compliant with the SFP MSA. Designed for SONET OC-3 (156Mb/s) OSC Application 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. Internal Calibration for Digital Diagnostics The transceiver operates from a single +3.3V power supply over an operating case temperature range of -5°C to +70°C (COM). The housing is made of metal for EMI immunity. 44dB link budget Compatible with SFP MSA Digital Diagnostics through Serial Interface Eye Safe (Class I Laser Safety) Duplex LC Optical Interface Excellent EMI & ESD Protection Hot-pluggable Absolute Maximum Ratings Parameter Storage Temperature Operating Case Temperature 1 Supply Voltage Maximum Input Optical Power Input Voltage Symbol Minimum Maximum Units TST - 40 + 85 °C °C TOP -5 +70 VCC 0 + 5.0 V Pin, max - + 3.0 dBm VIN 0 VCC V Measured on top side of SFP module at the front center vent hole of the cage. 1 An Oplink Company 21737-0972, Rev.A 2009-01-14 TRCE03KE2C000C3 Transmitter Performance Characteristics (Over Operating Case Temperature.

The high speed DATA interface is differential AC-coupled internally with 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 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 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. 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 that should be pulled up with a 4.7 - 10kΩ resistor on the host board. TX Fault is latched per SFP MSA. 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 0.1μF power supply bypass capacitors should be as close to the transceiver module as possible. 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).
