光纤接口缩写及全称(zt)

     今天看到接头光纤的种类，有ST FC SC LC MT—RJ，为了便于记忆想查一下他们的全称是啥？网上好容易查到了，竟然有这么多接口，顺便共享一下。

 

ST       Straight Tip

FC       Ferrul Connector

SC       Subscriber Connector

LC       LUCENT Connector

MT-RJ  Mechanical Transfer Registred Jack

 

记忆方法

• LC接头有时候称为小(Little)接头。
• MT-RJ接头看起来像比较小的8P8C接头。
• ST接头可用"刺入及旋转"(Stab and Twist)来记忆，刺入及旋转就是它的连接方法(将线插入插座，然后旋转外面的卡榫将之锁住)。
• SC接头可用"方形接头"(Square Connector)来记忆，并且有人认为这才是它的正确名称，因为接头本身是方形的。另一记忆方法是(Stick and Click)。
• FC的金属接头对光纤芯提供良好的保护，但它是用旋转的方式，对光纤芯容易造成刮伤。
• SC接头提供良好的包装强度，而且它的先推后拉的连接方式让光纤芯在连接过程中比较有保护。
• LC接头主要应用企业网络环境中，用来取代SC接头的，它的尺寸比较小。它也常见于SFP。
• ST接头有卡榫避免接头损毁，类似BNC接头。
• 对于所有接头，在连接前先清洁有助于保护光纤芯断面不受异物刮伤，延长接头寿命，且避免断面因受污染而影响信号强度。
