1、Fixed connection. Mainly used for permanent connection between optical fibers in fiber optic cable lines, mostly using fusion splicing, but also using bonding and mechanical connection. Characterized by low joint loss and high mechanical strength. Equipment needs to be fusion splicing machine, about tens of thousands of RMB
2、Active connection. Mainly used for fiber optic and transmission system equipment and the connection between the instrument, mainly through the optical connection plug for connection. Features are better flexibility of the connector, easy to swap connection points, loss and reflection is the shortcomings of this connection method. Now the plug loss aspect has also been very good, a few dozen RMB can be, you can directly buy finished products, if you want to bulk, but also need end polishing and grinding equipment, that is too expensive, it is recommended to buy jumper directly.
3, temporary connection. Measurement pigtail and the coupling connection between the fiber under test, generally use this method of connection. Features are convenient and flexible, low cost, the loss requirements are not high, temporary measurement is mostly connected in this way. You can also use a fusion splicer or V-slot with glue.
