There is something wrong with the router interface, and the optical cat needs to be replaced. This situation is rare.
The indoor tail fiber connection optical cat connector is loose. Plug in the connector and it will be restored.
Some indoor optical fibers are too bent. Excessive bending of optical fiber will affect the total reflection transmission of optical signals in optical fiber, as long as the optical fiber is straightened.
Some outdoor optical fibers are broken or the optical port of the equipment in the operator's computer room is faulty, which needs to be handled by the operator.
Brief introduction of router:
A router (also called a router) is a computer network device that transmits data to a destination through a packaged network (selecting the transmission path of data). This process is called routing. A router is a device that connects two or more independent networks. Routing works in the third layer of the OSI model-the network layer.
A router is a device that connects a local area network and a wide area network in the Internet. It will automatically select and set the route according to the channel conditions, and send signals in turn by the best path. Routers are the hub of the Internet and the "traffic police". At present, routers have been widely used in all walks of life, and products of different grades have become the main force to realize the internal connection of various backbone networks, the interconnection between backbone networks, and the interconnection between backbone networks and the Internet. The main difference between routing and switch is that switching takes place at the second layer (data link layer) of OSI reference model, while routing takes place at the third layer, namely network layer. This difference determines that routing and switching need to use different control information in the process of moving information, so the ways to realize their respective functions are also different.
The core force behind the 30% share
Not long ago, China Mobile announced the results of centralized procurement of high-end routers in 20 14 years, among which ZXR 106000-S products of ZTE obtained 30.77% share, ranking second in centralized procurement. The centralized bidding for mobile routers and switches in China was issued on August 22nd, and Cisco, Junbo and ZTE participated in the competition. In the end, ZTE successfully won the bid for high-end router 2 and high-end router 3, covering the scenes of China Mobile's high-end routers P, PE, SR and CE.
Behind the success of ZTE's high-end routers in centralized procurement of operators, ZTE has the advantage of its own core competitiveness. Liu Hengqi, chief engineer of ZTE Microelectronics, told the author that all the core chips used in ZTE's high-end routers were independently developed by ZTE Microelectronics. At present, the internal chips of ZTE cable products, such as packet switching sleeve, network search engine, network processor, Ethernet switch, OTNFramer, space division crossover chip, G/EPONOLT processor and terminal ONU/MDU, have all been independently developed.
The research and development of chips needs strong financial guarantee, which is difficult for small companies to do. At present, the research and development of a system chip generally requires tens of millions or even hundreds of millions of research and development expenses. ZTE has always attached importance to the independent research and development of chips in independent products and patent applications. On average, each chip will output 20-30 patents to better protect knowledge products. .
Chips provide operators with operation and maintenance capabilities-sponsored by Zhiyan Consulting
In addition, through long-term cooperation with domestic telecom operators, ZTE can better understand the needs of operators than other manufacturers. For example, for some transmission network equipment, the general product may be 100G, but the actual demand of operators may be 120G, so ZTE will customize chips and products for operators.
In addition, in the field of broadband access terminals, ZTE products using ZTE microelectronics chips have been distributed in EPON and GPON equipment in Shanghai. Operators hope to carry their own services on their broadband terminals to meet their own operation and maintenance needs. However, if the terminal uses ordinary commercial chips, it will be difficult to do this, and only the basic functions can be guaranteed.
