Graphic: Function and connection of optical cable, terminal box, pigtail
In the network cabling, usually the outdoor (connected between buildings) uses the optical cable, and the indoor (inside the building) uses the Ethernet twisted pair cable. Then, how to convert the optical cable transmission media outside the building and the Ethernet transmission media inside the building? ? Which equipment is used again? What is their role? What about the relationship between them?
as the picture shows:
Connection relationship:
Step 1: The outdoor optical fiber cable is connected to the terminal box. The purpose is to weld the optical fiber and the pigtail in the optical fiber cable, and lead it out through the jumper.
Step 2: The fiber jumper is connected to the fiber transceiver to convert the optical signal into an electrical signal.
Step 3: The optical fiber transceiver leads to electrical signals. The transmission medium used is twisted pair. At this point the twisted pair can access the RJ-45 port of the network device. This completes the conversion of the photoelectric signal.
Note: Many network devices now have optical ports (fiber interfaces), but if you do not have an optical module (similar to the fiber transceiver function), this port cannot be used.
Graphic: Function and connection of optical fiber terminal box and pigtail
Optical cable terminal box function: Terminate the optical cable, connect the core and pigtail in the optical cable, and the internal structure of the optical cable terminal box, as shown in the figure.
For example: A 4-core cable (4 cores in the cable), then this cable can be connected to the terminal box and can weld up to 4 pigtails, which leads to 4 jumpers. In the figure above, only two welds have been made and two jumpers have been introduced.
Pigtail: A connector at one end and a broken end of a fiber optic core at the other end. Through welding, with other fiber optic cable core connected.
Pigtail effect: It is mainly used to connect the connectors at both ends of the fiber. One end of the pigtail is welded to the fiber connector, and the other end is connected to the fiber transceiver or fiber module through a special connector to form an optical data transmission path.
Generally, we do not buy pure pigtails, but jumpers as shown in the figure. When the middle is cut, it becomes a pigtail.
Pigtail: Used in the terminal box to connect the optical fiber in the optical cable, and connect the pigtail and jumper through the terminal box coupler (adapter).
Jumper: Both ends of the jumper are active connectors. Connect pigtails and equipment.
Optical cable terminal box: It is a box that protects the optical fiber cable and protects the fiber cable from the tail fiber.
Fiber Optic Coupler: The active connection for two fibers or pigtails is commonly referred to as a flange.
Fiber optic terminal box: It is the terminal connector of a fiber optic cable. One end of the fiber optic cable is fiber optic cable, and the other is pigtail fiber. It is equivalent to a device that splits a fiber optic cable into a single optical fiber.
Optical fiber splice box: It is used to connect two optical cables to one long optical cable. They can not be used interchangeably. Fiber optic cables and optical transceivers are connected through optical fiber terminal boxes. That is, optical fibers can only be inserted into pigtails.
Can the terminal box and the fusion box be understood in this way? In which the two ends of the optical fiber are fused, but the former is the welding of the optical cable and the pigtail, and the latter is the welding between the optical cables.
The splice box and the terminal box are different. The splice box is fully sealed but it can not be fixed but the terminal box is not waterproof. The internal structure can fix the optical cable on one side and the fixed fiber coupler can only connect two pigtails on one side. And it is divided into SC/PCFC/PC and other interfaces, and the fusion between the optical cable and the pigtail is fused with the fusion splicer.
What is the difference between pigtail and jumper? Can the jumper be split into two for tail fiber use? Only one end of the pigtail is an active joint, and both ends of the fiber jumper are active joints. There are many types of interfaces, and different interfaces require different couplers. The fiber jumper is divided into two and can be used as tail fiber.

Optical cable terminal box function: Terminate the optical cable, connect the core and pigtail in the optical cable, and the internal structure of the optical cable terminal box, as shown in the figure.
As shown in the figure, the access cable can have multiple cores.
For example: A 4-core cable (4 cores in the cable), then this cable can be connected to the terminal box and can weld up to 4 pigtails, which leads to 4 jumpers. In the figure above, only two welds have been made and two jumpers have been introduced.
