With the extensive application of fiber optic communication technology, the optical transceiver industry is developing rapidly, and the video channels of optical transceiver are also increasing, including 1, 2, and 64 channels. However, from the market demand perspective, 16 channel video optical transceiver is currently the largest market demand. Users should pay attention to its video bandwidth and APL range when choosing 16 channel video optical transceiver. The video bandwidth should be wide enough. If the video bandwidth is insufficient, the details of the monitored image may not be clear enough, the horizontal resolution may be low, and in severe cases, color distortion or loss may occur; APL, also known as image average level, is a method of measuring the average video brightness level and expressing it as a percentage of the maximum white level. When APL is low, the image is dark, and when APL is high, the image is bright. At the same time, attention should also be paid to the after-sales service of video optical transceiver manufacturers.
