随着需求的增长,人们对网络的带宽、传输速度提出了越来越高的要求,在企业中,急剧增加的业务量加快了万兆网络的普及;在家庭中,对高清晰度电视和高速宽带网络服务的需求,加速着三网融合。然而,网络布线中被大量采用的铜缆,系统性能已经达到了极致,不能适应未来网络的要求。曾经是企业网络主干布线的光纤,由幕后走到了前台,光纤将取代铜缆成为下一代网络布线的主流,光纤到户(FTTH)、光纤到桌面(FTTD)已经成为不可逆转的趋势。下面笔者将网络中常用的光纤及光纤连接器、适配器、模块等连接器件进行简单的介绍。
With the increase of demand, people have set higher and higher requirements on the bandwidth and transmission speed of the network. In the enterprise, the sharp increase of the business volume has accelerated the popularization of the 10 Gigabit network. In the home, High-speed broadband network services demand, accelerating triple play. However, the extensive use of copper cables in network cabling has reached the limit of system performance and can not meet the requirements of future networks. Once the backbone of enterprise network cabling fiber, came behind the scenes from behind the scenes, fiber will replace copper as the mainstream of next-generation network cabling, FTTH (Fiber to the Home), FTTD has become an irreversible trend. The following author will be used in the network fiber and fiber optic connectors, adapters, modules and other connected devices for a brief introduction.
