With the development of Internet technology, the lifestyle has undergone tremendous changes. Today's clothing, food, housing, and transportation are inseparable from interconnection, and the network needs to rely on various equipment for transmission, such as optical cables, terminal boxes, pigtails, etc. They are all products that need to be used. Today, OMC will talk to you about the connection relationship and function of the optical cable terminal box and the pigtail.
The connection relationship of optical cable, terminal box and pigtail
1. The outdoor optical fiber cable is connected to the terminal box, the purpose is to weld the optical fiber in the optical cable with the pigtail, and lead it out through the jumper.
2. Connect the optical fiber jumper to the optical fiber transceiver, the purpose is to convert the optical signal into an electrical signal.
3. The optical fiber transceiver leads to electrical signals, and the transmission medium used is twisted pair. At this time, the twisted pair can be connected to the RJ-45 port of the network device. So far, the conversion of the photoelectric signal has been completed.
The role of optical cable, terminal box, pigtail
The function of the optical cable terminal box: terminate the optical cable, connect the core and pigtail in the optical cable, the internal structure of the optical cable terminal box, for example: a 4-core optical cable (there are 4 cores in the optical cable), then the optical cable passes through the terminal Box, you can splice a maximum of 4 pigtails, that is, 4 jumper wires are led out.
Pigtail: one end has a connector, and the other end is a broken end of the optical cable. Through fusion splicing, it is connected with other optical cable cores.
Pigtail: Mainly used to connect the connectors at both ends of the optical fiber. One end of the pigtail is fusion spliced with an optical fiber connector, and the other end is connected to an optical fiber transceiver or an optical fiber module through a special connector to form an optical data transmission path. Generally, we cannot buy pure Pigtail fiber, but cut them from the middle to become pigtail fiber.
