FUNCTIONAL DESCRIPTION
The Transceiver convert information from electrical to optical format, and back again, at different data rates depending upon the chosen standard.
The transmit path consists of an AC coupled 100 ohm differentially terminated driver coupled to a highly reliable 1310nm DFB. The laser output may be disabled by pulling the TX_DISABLE line high. The laser is also disabled if this line is left floating, as it is pulled high inside the transceiver. A fault condition is raised upon detection of an abnormal laser state. The RATE-SELECT is not implemented in the LRM module.
The receiver path consists of a ROSA (receiver optical sub-assembly) for optical electrical conversion, followed by a linear amplifier to boost the electrical signal. A LOSS_OF_SIGNAL (LOS) status line is provided to facilitate easy link detection. The receiver RATE_SELECT pin is not used by the transceiver.
Complete digital optical monitoring is implemented in compliance to SFF-8472 and made accessible via the 2-wire interface providing real time information about all important module parameters and status in- formation.

Digital Diagnostic Monitoring
Transceivers offer the ability to monitor important module parameter during operation. The five parameters listed below are continuously monitored for getting information about the current module status. All data is calibrated internally; there is no need for external post processing.
Temperature Internally measured temperature data is represented as two’s complement of a signed 16-bit value in increments of 1/256 °C over a range of -40 to +100°C. Accuracy is better than +/-3%.
Supply Voltage (VCC) Internally measured supply voltage. Represented as a 16-bit unsigned integer with the voltage defined as the full 16 bit value (0 – 65535) with LSB equal to 100 Volt, which yields to a total range of 0 to +6.55 Volts. Accuracy is better than +/-3%.
Laser Bias Current VCSEL bias current. Represented as a 16 bit unsigned integer with the current defined as the full 16-bit value (0 – 65535) with LSB equal to 2 A, valid range is 0 to 20 mA. Accuracy is better than +/-10%.
Optical Transmitter Power TX output power measurement is based on internal monitor diode feedback. Represented as a 16-bit unsigned integer with the power defined as the full 16 bit value (0 – 65535) with LSB equal to 0.1 W. Accuracy is better than +/-3dB over a range of Pavmin to Pavmax.
Receiver Optical Power RX input power measurement is based on photodiode diode current. Represented as a 16-bit unsigned integer with the power defined as the full 16 bit value (0 – 65535) with LSB equal to 0.1 W. Accuracy is better than +/-3dB over a range of -12dBm to -1dBm.
