Diagnostics monitoring functionality (alarm and warning features) is integrated into the design via an I2C serial interface per the Multi-Source Agreement (MSA) on DWDM SFP transceivers (Rev. 1.0, October 2005). Products under this series are compatible with SONET/SDH standards for OC-48/STM-16 (2.67Gb/s) Forward Error Correction and OC-48/STM-16 (2.488Gb/s) LR-2/L-16.2 long reach applications, OC-3/STM-1 (156Mb/s) and OC-12/STM-4 (622Mb/s) SR/I-1 and I-4 short reach applications; Gigabit Ethernet LX (1.25Gb/s) applications per IEEE 802.3; and Fibre Channel 200-SM-LC-L (2.125Gb/s) and 100-SMLC-L (1.062Gb/s) applications per FC-PI standards. The transmitter incorporates a highly reliable 1550nm DFB laser with an operating wavelength in full compliance with 100GHz (0.8nm) spacing per ITU-grid. All transceivers are Class I Laser products per U.S. FDA/CDRH and international IEC-60825 standards. Features Compliant with DWDM SFP MSA Multi-rate Operations from 125Mb/s to 2.67Gb/s The TRPW48L2/E2 DWDM transceivers connect to standard 20-pad SFP connectors for hot plug capability. This allows Support 2.67Gb/s OC-48 FEC Rate 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. Long Haul Transmission Distance of 80km or 120km The transceivers have blue bail-type latches, which offer an easy and convenient way to release the modules. The latch is compliant with the SFP MSA. The transmitter and receiver DATA interfaces are AC-coupled internally. LV-TTL Transmitter Disable control input and Loss of Signal (LOS) output interfaces are also provided. The transceivers operate from a single +3.3V power supply over an operating case temperature range of -5°C to +70°C (Commercial) or -5°C to +85°C (Extended). The housing is made of metal designed for optimum thermal performance and electromagnetic compatibility. 1550nm DFB Laser Transmitter & APD Receiver Compliant with G.692 100GHz Channel Spacing Optical Link Power Budget of 28dB Minimum Digital Diagnostics through Serial Interface Internal Calibration for Digital Diagnostics Eye Safe (Class I Laser Safety) Hot-pluggable TX Fault & Loss of Signal Outputs TX Disable Input Temperature option of -5°C to +85°C Absolute Maximum Ratings Parameter Storage Temperature Operating Case Temperature1 Commercial Extended Supply Voltage Maximum Input Optical Power (30 seconds max.)

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 Serial Identification and Monitoring: The module definition of SFP is indicated by the three module definitionpins, MOD_DEF(0), MOD_DEF(1) and MOD_DEF(2). Upon power up, MOD_DEF(1:2) appear as NC (noconnection), 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 Start-up: During power up or hot plugging the DWDM SFP module will initially set the TX to the correct operating temperature. Depending on the ambient temperature this may take several seconds to 1 minute. When the Tx has reached the required temperature the Tx is switched on and active. At this point the Tx is guaranteed to be within +/-0.2nm of the appropriate ITU wavelength and will settle to +/-0.05nm within the time limit set by the MSA. The data transfer protocol and the details of the mandatory and vendor specific data structures are defined in the MSA. 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. Power supply and grounding: The power supply line shouldbe 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).
