As a core component of 5G base station construction, photoelectric modules play an important role in realizing photoelectric conversion. For a long time, the optical module market has been monopolized by foreign manufacturers, especially in the field of high-end optical communication chips. However, with the accelerated development of domestic new infrastructure and the development of 5G industry, the number of domestic optical module market demand has gradually begun to increase.

In 5G bearer technology solutions and industry research. Dr. Tang, an optical transmission expert at the China Academy of Telecommunication Research, mentioned that the 5G backtrip scheme is relatively unified, and the access layer is mainly 25G and 50G. In the early stage of construction, the bandwidth and capacity of 5G have not yet expanded, and the 25G first-level backhaul can basically meet the demand, with the expansion of the network scale and network concentration, 50G and 100G will appear in the network access layer. In the future, in the convergence layer and the core layer, the current 100G is the mainstream. With the expansion of network scale and network concentration, it is possible to reach 400G in the future, and even use WDM technology to increase capacity.


Laser welding solutions for optical modules

There are several technologies for 5G prequel. The most mature CWDM is the earliest and most mature. It can support 6 waves, while LWDM/ MWDM supports 12 waves of 25G, and can further save fiber. For optical modules, the front 25G / 10G interface is compatible, and the technology in this field is also very mature. For 100G, high-density and low-power packages are needed, such as the SFP28. The overall demand for 5G construction must be low-cost and interconnected, and interconnection can substantially reduce costs.

Under the co-construction and sharing model, CRAN will become the main application scenario. CRAN has the following advantages: 1. Compared with DRAN, CRAN can reduce the need for terminal room and transmission equipment, and save site acquisition, room rental and transmission costs. In theory, the higher the concentration, the more obvious the effect. 2. The centralized placement of DU facilitates unified maintenance, so it has certain advantages over DRAN in construction and maintenance cost. CRAN will become the main deployment mode for 5G construction. 3. At the same time, the CRAN method can realize DU pooling or cloud, and share and multiply baseband resources. Business collaboration between sites. Since CRAN consumes more front-pass fiber, xWDM will become mainstream.

The development of optical communication modules has opened up the industrial market for laser welding

With the gradual expansion of 5G commercial operations, the explosive growth of 100G optical modules will certainly drive the explosive growth of 100G optical modules. At present, mainstream optical module manufacturers have begun to develop and produce 100G optical module components. However, the traditional welding process leads to a decline in the qualified rate of the product. Automatic laser temperature control laser welding perfectly solves the problem of mass production of 100G optical modules. Approved by Huawei, Accelink and other customers, it has achieved mass production.


Product overview

Constant temperature precision laser tin welding machine is the standard welding equipment of our company, which is mainly composed of automatic tin point device/automatic tin wire feeding device, infrared real-time temperature feedback system, CCD coaxial positioning system, and semiconductor laser. The company's self-developed constant temperature laser tin welding software can achieve hierarchical processing of processing parameters for different solder joints and different heights, and at the same time can monitor the completion of operations in real time during the welding process. PID online temperature adjustment feedback system can control the constant temperature welding, improve the welding yield and precision.
