光端机已不仅仅是模拟标清传输的工具了,而是往高清化和集成化去发展。一方面是为了适应市场上越来越多的高清传输需求,演变出hd-sdi光端机这样的产品。另一方面是为了满足类似于公安三级网,四级网这样的大容量的传输需求而演变出的高度集中化的光端机产品。
Optical is not only a tool for analog SD transmission, but to HD and integration to develop. On the one hand is to adapt to the market more and more high-definition transmission needs, evolved hd-sdi Optical end product. On the other hand is to meet similar to the public security three network, four network such large-capacity transmission needs evolved out of the highly centralized optical products.
