Since the year before, based on Gigabit Ethernet fiber optic cable has been very rapid development.

In the LAN backbone network (backbone) are used almost most of the fiber-based Gigabit Ethernet. In gigabit fiber optic links in the network of fiber optic cable link connection with the way the new changes have taken place.

1, the traditional way of fiber optic cable link connection

The traditional way of fiber optic cable link connection is mainly ST, SC or FC connection mode. At present they are still in heavy use. The shape shown in Figure 1. These simple cable connection, the connection can be independent of each cable are used. In other words, when you install the fiber optic cable links, does not know is if the actual use of these cables, that does not know the direction of signal transmission cable. In actual use, the cable and network devices, it is necessary first to determine the transmission of signals in the direction of the fiber optic cable can be connected correctly. In addition, the production of waterproof connectors of fiber optic cable is not convenient, requires special tools.

2, the new cable connection

As you know, when Gigabit Ethernet is the connection cable used in pairs children, that is an output (output,tru_1wt but also as the light source), an input (input, optical detector), such as routers and switches, fiber optic cable connections. If, when used, can be used together in pairs without regard to the direction of the connection, and connection simple and convenient, it will help to Gigabit Ethernet connections. So a lot of fiber cabling manufacturers to launch a variety of waterproof connectors meet this application.

This new cable waterproof connectors called SFF (SmallFormFactor). But there is no clear terminology to describe, we generally call it micro-fiber waterproof connectors. Most SFF cables currently on the market there are four types of waterproof connectors. LC type, which is Lucent has introduced a SFF type of waterproof connectors. FJ types, it is waterproof connectors company introduced waterproof connectors.

MT-RJ-type, which is launched by the United States, AMP connectors, and by the 3M company introduced the VF-45 waterproof connectors. The figure is that the several types of waterproof connectors. This waterproof connectors is a pair of children and the patch cable connected with the direction is fixed. Therefore, more convenient in actual use, it will not mistakenly inserted
