Is Huijue Communication not a type of optical module

Huijue Communication does not produce optical modules; it specializes in outdoor communication cabinets and related infrastructure equipment.Huijue Communication, officially Haian Huijue Network Communication Equipment Co., Ltd., focuses on providing hardware, software, and technical services for wired and wireless transmission infrastructure, including outdoor cabinets, optical fiber splitter boxes, energy storage equipment rooms, and ETC cabinets for operators like China Mobile, China Unicom, and China Telecom . Their expertise lies in R&D, production, and sales of integrated communication equipment, not in manufacturing optical transceivers.What Optical Modules AreAn optical module is a hot-pluggable device used in high-bandwidth fiber-optic communication systems. It functions as a photoelectric converter, transforming electrical signals into optical signals and vice versa, and typically connects to a system via an electrical interface while linking to fiber optic cables through an optical interface . Common types include SFP, SFP+, QSFP, and CFP modules, which are used in data centers, telecom networks, and high-speed interconnects .Key DistinctionThe main distinction is that optical modules are active electronic components designed for signal conversion in fiber-optic networks, whereas Huijue Communication's products are primarily passive infrastructure equipment, such as cabinets and enclosures that house network devices and protect them from environmental factors . Therefore, Huijue Communication does not fall under the category of optical module manufacturers.
