Description

Technical Field

[0001] The utility model relates to the technical field of communication transmission, and particularly relates to a POF optical and electrical composite transmission component. Background Art

[0002] With the continuous development of the optical fiber communication industry, people's demands for large-scale data exchange and high-quality network transmission are also increasing continuously. The original optical fiber cable pipeline resources are difficult to meet the requirements of power supply for servers and large data transmission.

[0003] In the prior art, to meet the requirements of power supply for servers and large data transmission, optical cables are needed for information transmission and electric cables are needed for power transmission. For example, in the market, POE switches generally include multiple RJ45 electrical ports and several optical fiber ports. The RJ45 electrical ports can provide power to terminals and communicate at the same time. The optical fiber ports generally insert optical modules and then access optical cables through the LC interfaces of the optical modules.

[0004] Compared with RJ45 electrical port communication, optical fiber communication can provide a longer transmission distance and higher stability. It has become a trend to upgrade the original network system from cable communication to optical fiber communication. Currently, with the gradual popularization of optical fiber communication, POF switches appear in the market, that is, they provide power while providing optical fiber communication. The corresponding terminal devices are optical fiber access points (Access Point, AP), passive optical access systems (Gigabit-Capable PON, GPON) devices. When using a Protocol Oblivious Forwarding (POF) switch, the corresponding optical AP, GPON and other devices with power receiving functions do not need to be additionally connected to a power supply and can directly access through the Subscriber Connector (SC) of the optical transceiver to communicate and be powered on. However, these optical AP, GPON and other devices cannot be directly connected to the existing POE switches, and generally, the switches and the corresponding terminal devices need to be replaced at the same time.
