Digital Diagnostic Functions
SFP-10G-LR incorporates a XFP compliant 2-wire management interface which is used for serial ID, digital diagnostics, and certain control functions. It is modeled on the SFF-8472 Rev 9.3 specification modified to accommodate a single 2-wire interface address. In addition to the basic I2C read/write functionality the modules support packet error checking that, when enabled, allows the host system to confirm the validity of any read data. Details of the protocol and interface are explicitly described in the MSA. And the digital diagnostic functions via a 2-wire serial interface can provide real-time access to following operating parameters:
a. Transceiver Temperature
b. Laser Bias Current
c. Transmitted Optical Power
d. Received Optical Power
e. Transceiver Supply Voltage

Transmitter Section
The transmitter consists of a laser driver chip and a TOSA (light-emitting component). The TOSA includes a laser, an electroabsorption modulator (EAM), a TEC, and a backlight diode. Unlike DML, EML TOSA uses external modulation. When the transmission rate of the system is high, the transmission distance is not only limited by the attenuation of the optical fiber, but also by the dispersion of the optical fiber, and the dispersion of the optical communication system is related to the modulation spectral width. The directly modulated laser has a large dispersion cost, and has spectral broadening, frequency chirp, and short transmission distance, so the external modulation method is adopted in the medium-longdistance transmission at a rate of 10 Gb/s.TEC (Thermo Electric Cooler) Controls the temperature of the laser tube.When a temperature is set, the TOSA temperature of the module will remain unchanged through the control of the TEC.The wavelength of the module laser tube is related to the temperature of the laser tube. The module wavelength can be set by setting the TOSA temperature.When stable, the module has excellent wavelength stability. The electrical signal enters the optical module from the serial electrical interface and is then input to the laser driver chip. The laser driver chip supplies the bias current and the modulation current to the laser.The laser driver chip simultaneously uses an automatic optical power control (APC) feedback loop to maintain a constant average optical power of the laser output. The purpose is to eliminate the change of the output optical signal due to temperature changes and aging of the light source device.Clock Data Recovery Module (CDR) overcomes board and connector degradation by reshaping, regenerating, and reducing jitter.TX_DIS is a input pin. When TX_DIS is asserted High, the XFP module transmitter output must be turned off. The receiver consists of a ROSA (light receiving component) and a limiting amplifier chip, ROSA includes a PIN photodetector and a transimpedance amplifier chip.The ROSA detects the incident optical signal, converts the optical signal into an electrical signal, and outputs the electrical signal to the limiting amplifier. The limiting amplifier further amplifies the input signal and outputs a fixed amplitude electrical signal, and then shapes and synchronizes the electrical signal to the host through the CDR.Clock Data Recovery Module (CDR) overcomes board and connector degradation by reshaping, regenerating, and ModuleTek Limited ezoptics.en.made-in-china.com page5 XFP-10GB-LR-C10 Specifications reducing jitter.The RX_LOS of an output pin, when LOS is high, it indicates insufficient optical power for reliable signal reception.MOD_NR is an output pin. When it is high, it indicates that the module detects the condition that invalidates the transmitter/receiver data. The transmission signal regulator loses lock, the transmitter laser fails, and the receiver signal regulator loses lock. Etc.The micro controller unit initializes the control register of laser driver, limiting amplifier and CDR. And monitors the running information from the laser driver, limiting amplifier and CDR. Then report these information to the customer.
