RINxOMA is a metric used to evaluate the ratio of relative intensity noise (RIN) to optical modulation amplitude (OMA) of an optical module, which reflects the noise performance and signal quality of the optical module. This paper describes a method for RINxOMA testing using the MP2110A instrument and analyses the advantages and application scenarios of the method.

Keithley 2400 Digital Source Meter is an advanced multifunctional power supply and measurement instrument, which is widely used in current measurement in various fields. Switch on the instrument and connect Keithley 2400 Digital SourceMeter to a computer, set the following parameters through the instrument panel or remote control software: measurement mode, current range, sampling rate, trigger mode, etc.

Keithley 2400 Digital Source Meter is an advanced multifunctional power supply and measurement instrument which is widely used in current measurement in various fields. This article describes how to use Keithley 2400 Digital SourceMeter to measure current, including setting measurement parameters, connecting circuits and analysing results. Before measuring current, you need to set the measurement parameters. Turn on the instrument power and connect Keithley 2400 Digital SourceMeter to the computer, set the following parameters through the instrument panel or remote control software: measurement mode, current range, sampling rate, trigger mode and so on. Measurement mode can choose continuous measurement mode or single measurement mode, according to the actual demand. The current range is selected according to the estimated value of the measured current to ensure that the current does not exceed the rated range of Keithley 2400.

Optical communication is a technology that uses optical signals to transmit information in optical fibres or other media, which has the advantages of high transmission rate, large bandwidth and strong anti-interference. In order to evaluate the performance of optical communication system or optical module, some optical communication test parameters need to be measured and analysed, which include transmit optical power, receive sensitivity, extinction ratio, bit error rate, eye diagram and so on. This paper will briefly introduce the meaning, measurement method and analysis significance of these parameters.

Industry news, recently Minister of Industry and Information Technology Jin Zhuanglong said at the China-Africa Digital Capacity Building Cooperation Forum that China has strengthened the construction of digital and information and communication network infrastructure, and has built the world's largest and technologically leading fibre-optic and mobile communication network. Among them, the average annual growth rate of data centre scale in the past five years has reached nearly 30%.
