Active optical fiber cables are widely used for the interconnection of audio and video teaching equipment in multimedia classrooms. By supporting high-resolution audio and video signals (such as 4K/8K) and long-distance stable transmission, it ensures lossless signal connection between projection equipment, high-speed cameras, smart whiteboards and sound systems, realizes high-definition teaching images and high-fidelity sound effects, and creates a more immersive classroom experience.
In distance education and online teaching, active optical fiber cables can support the real-time transmission of high-quality audio and video data, and efficiently connect cameras, microphones, and display devices, so as to achieve high-definition live broadcast, delay-free teacher-student interaction, and smooth collaboration between multiple terminals, providing smooth audio and video transmission guarantee for online teaching.
