Optical module test, have you selected the right power supply?

With the rapid development of the mobile communication industry, 5G has become a super hot topic in the world. Compared with 2G, 3G, and 4G, the status of 5G in the optical fiber communication industry in the future cannot be underestimated. In the 5G network era, no matter what kind of 5G bearer All solutions are inseparable from 5G communication optical modules. Diversified standard 5G communication optical modules are now considered to be the core technology of the next generation of high-speed and large-capacity optical networks.

The optical module is an optical device composed of an optical device, a functional circuit and an optical interface. Its main function is to realize the photoelectric conversion in the optical communication system, convert the electrical signal into an optical signal at the sending end, and then transmit it to the receiving end through an optical fiber. The receiving end converts the optical signal into an electrical signal. 5G communication optical modules have the advantages of small size, high speed, and low power consumption, and can be used in communication fields such as data centers, transmission networks, and mobile broadband.
According to data from Light Counting, a third-party market research organization in the optical communication industry, in 2020, with the continuous growth of global data traffic, the overall global sales of optical modules in 2020 will exceed US$8 billion, a year-on-year increase of 23%. It is expected that the global optical module market will grow to about US$11.3 billion in 2025, and US$14.5 billion in 2026, with a compound annual growth rate (CAGR) of about 10% in 2021-2026.
Benefiting from the construction of data centers and the in-depth layout of 5G networks, the global market share of domestic optical module companies has further increased. The demand of downstream operators of optical modules is expanding, and the industrial chain is gradually concentrated in China. China's optical module market is bound to further grow. In 2022, the size of China's optical module market is expected to exceed 3 billion yuan, and the growth rate is expected to surpass that of the world.
With the continuous development of the optical module industry, related industries will surely make adaptive changes. In the field of low-power test instruments, there will also be more challenges. Regarding the testing of optical modules, whether it is the interoperability and compatibility testing of optical modules, or other tests such as performance parameters, there are strict requirements on the test power supply
Case application:
A customer plans to choose a low-power DC power supply to test the electrical performance of optical modules. The dynamic response time of the power supply is required to be less than 20us, the voltage rise and fall time is less than 5ms, and the current accuracy is at the mA level.
The low-power products currently on the market can hardly meet the speed and accuracy requirements of optical modules at the same time. In this regard, ITECH's IT6341C dual-channel high-precision DC power supply solves this problem well.
IT6341C dual-channel high-precision DC power supply can meet the dual needs of low-voltage high-current and high-voltage low-current in the low-power test of users at the same time. On the other hand, IT6341C meets the market demand for low-power high-performance power supply. It has ultra-high precision, ultra-fast voltage rise and fall speed, ultra-high dynamic response time and ultra-low ripple, which can meet the stringent test indicators of low-power test users.

In addition, IT6341C dual-channel high-precision DC power supply has high resolution, high precision and high stability, and has over-voltage and over-heat protection functions. In addition, series and parallel working modes are provided to enhance the output capability of voltage or current. The resolution is as high as 1mV/1mA, which can meet various application requirements. It can be widely used in optical communication module testing, semiconductor testing, chip and integrated circuit testing, industrial ATE testing, school laboratories, production testing on production lines, maintenance testing, etc. field. It is an excellent choice for R&D departments, manufacturers and teaching and scientific research units.
