In network cabling, optical cables are usually used outdoors (connection between buildings), and Ethernet twisted-pair cables are used indoors (inside buildings). Then, how to switch between the optical cable transmission medium outside the building and the Ethernet transmission medium inside the building? What is the relationship between the optical cable, terminal box, and pigtail? Huijue Network will answer for you.

The outdoor optical cable is connected to the terminal box, the optical fiber in the optical cable and the pigtail are fused, and then lead out through the jumper. The fiber optic jumper is connected to the fiber optic transceiver, the purpose is to convert the optical signal into an electrical signal. The optical fiber transceiver leads to the electrical signal, and the transmission medium used is the twisted pair. At this time, the twisted pair can be connected to the RJ-45 port of the network device. So far, the photoelectric signal conversion has been completed.

What is the relationship between optical cable, terminal box and pigtail?

The function of the optical cable and the terminal box is to terminate the optical cable, connect the core and the pigtail in the optical cable, and the internal structure of the optical cable terminal box. The incoming optical cable can have multiple cores. A 4-core optical cable, then, this optical cable can be spliced with up to 4 pigtails after passing through the terminal box, that is, 4 jumpers can be drawn out. If only 2 wires are welded, 2 jumper wires will be drawn out.

The role of the pigtail: it is mainly used to connect the connectors at both ends of the optical fiber. One end of the pigtail is fused to the optical fiber connector, and the other end is connected to the optical fiber transceiver or optical fiber module through a special interface to form an optical data transmission path. Generally, we can’t buy pure pigtails, but optical fiber jumpers. Once the middle is cut, it becomes a pigtail.
