TCL Building switch makes Community Ethernet access simple and efficient

TCL Network Equipment Co., Ltd. TCLS4109SFB, is a simple network management switch, is a team-level network equipment, on the basis of the mature chip scheme, specifically for the community users of broadband access to sudden high traffic, diversified natural environment conditions and other characteristics of the optimization design, so as to obtain small volume, Good sealing and wide operating temperature and humidity range provides simple and efficient building solutions for Community FTTB Ethernet access.

According to the demand of the media condition of the broadband network access, in addition to the 8-port 10/100m RJ-45 interface, TCLS4109SFB has specially designed 1 100base-fx fiber interface, which is based on the function of electrical signal line connection of ordinary switch products. It also has the function of reliable conversion between electrical signals and optical signals. Fiber to the floor, electric mouth to the door, users need only a 10/100m Ethernet card, you can enjoy 100M to the desktop of high-speed bandwidth brought about by the high efficiency and convenience.

As a public network of Internet access, the data communication mode is mainly star-oriented, that is, the user does not need direct communication, and in order to protect the security of users, it can not be allowed to communicate directly. The general hardware vendor's approach is to partition the data stream in the second layer of the Osi/iso-the data Link layer-by setting up the switch's VLAN. S4109SFB supports the maximum of 7 VLAN (virtual subnet) division, can well meet the single floor security needs of ordinary huxing, at the same time using port based VLAN division, the network maintenance difficulty to minimize.

The S4109SFB adopts 2Mb port buffer space, which is used to coordinate the speed matching between different network devices, and store burst data in the buffer to be processed by the slow device, so as to avoid the sudden high traffic congestion of the Community users at a certain time period (such as 8-10 points at night). At the same time, the S4109SFB adopts advanced and mature buffer scheduling algorithm, which reduces the addressing time of the switch in normal communication state, effectively controls the cost of the equipment and avoids errors in packet loss.

Based on the reliable product quality, the carrier can construct seamless 10/100mbps Ethernet Exchange Network system and provide unified Network Service for the whole network system, which is simple and reliable in structure, and integrates the scalable network speed and performance with S4109SFB. S4109SFB has been widely used in community intelligence construction, the current Yangzhou radio and television community construction, Zhenjiang radio and television construction projects in a large number of thousands of S4109SFB as building access switch.
