The "last mile" of Internet communication refers to the connection from the communication service provider's computer room switch to the user's computer and other terminal devices.
The users involved in the "Last Kilometer" refer to users in the status of network terminals such as home and personal users or small business users, not large business users or professional communication companies. Therefore, the line connecting service providers and users will not It is a single-mode fiber commonly used in backbone networks. "Last mile" also involves the problem of wiring at the location where the user's computer and other terminal equipment are located. Since each user's room is different, the communication service provider, real estate developer and user need to consider according to the actual situation. How to connect user equipment to the network, how to migrate to other locations, and how to log off user services.
Optical fiber has become the first choice for the transmission method of the communication network due to its communication frequency bandwidth, low loss, high fidelity, and strong anti-interference ability. The main communication part of the existing communication network has basically been fiberized, and in recent years As the price of optical fibers continues to dive, the cost of installing optical fibers has continued to decline, resulting in the possibility of direct access of optical fibers to end-user terminals. Fiber homes have begun to spread in developed countries.
In modern intelligent buildings and various office environments, computer networks are widely used, especially LAN technology with Ethernet technology as the core, occupying most of the market. In various networks, the number of nodes and ports is increasing, and the transmission speed is getting faster and faster. At present, the development from 10Mbps and 100Mbps to 1Gbps has begun. All-fiber port equipment (network optical fiber transceivers) has also gradually developed from the backbone connection to the desktop.
The problem that must be solved for the fiber to the home is the problem of photoelectric conversion, that is, the conversion of short-distance twisted pair and long-distance optical signals. Most of the network equipment such as computers used by ordinary users do not have fiber optic interfaces and cannot communicate with the backbone. The network directly communicates through the optical fiber, and the conversion from the network port to the fiber must be performed through the photoelectric converter, so that the network equipment with only the network interface has the optical fiber interface to communicate with the optical fiber of the backbone communication network. Shenzhen Yutai Technology's photoelectric converter provides the network Port-to-fiber, providing an optical fiber interface to connect with the backbone communication network upwards, and a TCP / IP network interface to connect to network devices such as computers downwards, so that the computer can be directly connected to the optical fiber communication through the photoelectric converter.
In the reality that the comprehensive access to broadband access networks is difficult, the industry has proposed many solutions, such as fiber to the building (FTTB), fiber to the node (FTTN), fiber to the remote (FTTR), fiber to the switch box (FTTC ) Etc., collectively referred to as FTTx. Among them, FTTB is particularly popular because it is suitable for metropolitan areas with dense populations and multi-residential unit buildings such as rental apartments, residential buildings, and hotels.
Yutai UT-2571MM 10 / 100M optical fiber transceiver is used for data communication between 100Base-TX twisted pair and 100 Base-FX optical cable or between 10Base-T twisted pair and 10Base-FL optical cable. It is most suitable for intelligent communities or optical fiber to the desktop The connector automatically adapts to the transmission rate of 10Mbps and 100Mbps, which is convenient for users to upgrade. It extends the limit of network transmission distance from 100M of twisted pair to more than 100KM, which can easily realize the interconnection between motherboard server, repeater, hub, terminal and terminal.
