10Gbps 1550nm XFP Optical Transceiver

7. 2-Wire Serial Interface

XFP module has 2-Wire Serial Interface (SDA, SCL), which allows host to monitor some operating parameters and

to set some parameters to control the XFP module. As for the detail information of 2-Wire Interface, please see the

XFP MSA specification document.

7.1 Digital Diagnostic Functions

Digital Diagnostic Functions are provided using 2-Wire Interface. It provides the following operating

monitoring function to Host.

1) Internally Measured Transceiver Temperature

Represented as a 16 bit signed twos compliment value in increments of 1/256 degrees Celsius valid.

The accuracy is better than +/-3 degrees Celsius over specified operating case temperature and voltage.

2) Measured TX Bias Current in uA

Represented as a 16 bit unsigned integer with the current defined as the full 16 bit value with LSB equal to

2uA, yielding a total measurement range of 0 to 131uA.

The accuracy is better than +/-10% over specified operating case temperature and voltage.

3) Measured Tx Output Power in mW

Represented as a 16 bit unsigned integer with the power defined as the full 16 bit value with LSB equal to

0.1uW, yielding a total measurement range of 0 to 6.5535mW (8.2dBm). Data is based on measurement of

laser monitor photodiode current.

The accuracy is better than +/-2dB over specified operating case temperature and voltage.

4) Measured RX Received Optical Power in mW

Value can represent either the average received power. Represented as a 16 bit unsigned integer with the

power defined as the full 16 bit value with LSB equal to 0.1uW, yielding a total measurement range of 0 to

6.5535mW (+8.2dBm).

The accuracy is better than +/-2dB over specified operating case temperature and voltage.

5) Internally Measured Transceiver Supply Voltage

Represented as a 16 bit unsigned integer with the voltage defined as the full 16 bit value with LSB equal to

100uV, yielding a total measurement range of 0 to +6.55V.

The accuracy is better than +/- 3% over specified operating case temperature and voltage.
