How to connect the cable

Methods include permanent connections, emergency connection, active connection.

           1 permanent optical connection (also known as hot-melt):

           This connection with the discharge of the method to root the melting point fiber opticconnection and connect together. Generally used in long-distance follow, permanent orsemi-permanent fixed connection. Its main feature is to connect all of the connectionmethod of attenuation in the lowest, typically 0.01 ~ 0.03dB / point. But the connection, you need special equipment (welding machines), and professionals to operate, and the connection points also need special containers to protect them. (2) emergency connections (also known as) cold fusion:

           Emergency connection is mainly used mechanical and chemical methods, the twofiber-optic fixed and bonding together. The main features of this method is fast and reliableconnection, connect a typical attenuation of 0.1 ~ 0.3dB / point. However, long-term useconnection points will be unstable, decay will be greatly increased, so only a short timeemergency use.

           3 Active Links:

           Active connections is to use a variety of fiber optic connection devices (plug andsocket), a site with the site or cable to connect up with a way. This approach flexible,simple, convenient, reliable, and is used in building the computer network cabling. The typical attenuation of 1dB / connector.
