Currently, 100G Ethernet has become the dominant standard in data centres, but with the emergence of new technologies such as 5G, IoT and AI, 100G Ethernet can no longer meet future demands and 400G Ethernet has become the new target. To achieve higher bit rates at the same baud rate, it is necessary to use higher-order modulation, such as PAM-4 (Pulse Amplitude Modulation, 4th order) signalling, which carries two bits of information in each symbol to achieve twice the bit rate.

With the rapid development of the Internet, data centres and cloud computing have an increasingly high demand for network bandwidth. High-speed optical modules, as the core equipment for network transmission, have a direct impact on the performance and quality of network stability and efficiency. At present, 800G and 400G high-speed optical modules have become the mainstream choice for data centres and cloud computing, but how to effectively test these high-speed optical modules to ensure that they meet the relevant technical standards and application requirements is an urgent problem.

Passive optical network (PON) is a fibre-optic access technology that distributes fibre-optic signals to multiple users through a passive splitter, achieving the goal of fibre-to-the-home (FTTH).PON technology has the advantages of high transmission rate, wide coverage, low cost, energy saving and environmental protection, and it has become one of the mainstream technologies for broadband access. With the increasing demand of users for high-speed broadband access, PON technology is also developing continuously, from the initial GPON (Gigabit Passive Optical Network) and EPON (Ethernet Passive Optical Network), to the later 10G PON (10 Gigabit Passive Optical Network), and then to the latest 25G PON (25 Gigabit Passive Optical Network), the downlink rate of the PON technology has been increased by 25 times, reaching the level of 25Gbps. the level of 25 Gbps. This article will introduce the key technologies of 10G PON and 25G PON, as well as their advantages and application scenarios.

The Model 2450 System SourceMeter® instrument is a precision, low-noise instrument that combines a stable DC power supply with a repeatable, high-impedance multimeter. The instrument is designed for intuitive setup and control, enhanced signal quality and extended ranges, and resistivity and resistance capabilities that are superior to similar products on the market. With both 6½-digit resolution and 0.012% basic accuracy, the 2450 provides 59 readings per second over the IEEE-488 bus. At 4½-bit accuracy, up to 1359 readings per second can be read into its internal buffer.

A Source Measurement Unit (SMU) is an instrument that combines a signal source function and a measurement function on the same pin or connector. It can supply voltage or current and measure voltage and/or current simultaneously. It integrates the functions of a power supply or function generator, a digital multimeter (DMM) or oscilloscope, a current source and an electronic load into a single, tightly synchronised instrument.

As network service providers introduce new applications and data volumes grow exponentially, 100G optical modules are being used in a large number of applications.
To improve productivity and save costs, optical module manufacturers are struggling to find inexpensive but scalable test instruments that can support a smooth upgrade from 10G to 25G or higher rates.
To improve production efficiency and save costs, optical module manufacturers are looking for inexpensive but scalable test instruments that can support a smooth upgrade from 10G to 25G or higher rates.
