Jiaozuo Institute of Technology campus in building a new campus at the beginning, put an intelligent building as the construction of the direction of the campus network. In accordance with the construction of intelligent campus network standards, the full realization of office automation, teaching automation and management automation. Thus, Jiaozuo Institute of Technology asked their campus network cabling system must meet the intelligent network voice and data transmission needs.
Overall planning, system design
Integrated wiring system to the voice and data communications equipment, switching equipment and other information management systems linked to each other, through a variety of components, including transmission media, line management, connectors, plugs, adapters, transmission electronic circuits, electrical protection and other facilities, construction various subsystems to the communications system for the campus network, computer network systems, and automated management of communications College of routing and route management.
Jiaozuo Institute of Technology cabling system, mainly referring to the premises wiring. Jiaozuo Institute of Technology campus network cabling system wide scope, involving 12 family wings and two faculty buildings, two laboratory building, two school buildings, 10 office buildings, a library, 12 student dormitory a total of 5,127 information points. Network covers a wide range of levels of complexity, diversity of application environments, for voice applications, data transmission, video film and television transmission demanding, calling for full office automation to help achieve campus, teaching management automation, to meet all kinds of video and audio teaching system and other large traffic data transmission requirements. Taking into account the characteristics of these applications, all of the information point by Institute of D-Link Super unshielded cabling solutions.
According to the functional characteristics of campus and a number of system requirements, taking into account the future expansion of space, Jiaozuo Institute of Technology designed a system in place a comprehensive program of information in determining the points, the re-design floor wiring between the number and location, to achieve a point to line, the system layout.
The entire system structure 3 star: Building the backbone for the inter-level, inside the building as the two main horizontal portion 3. Floor was divided into two main rooms, a school network by the center to the office building, laboratory building, teaching building, library, student activity center, outdoor fiber-optic radiation by the families of area; floor, the joint topology between the two main centers student recreation center, library and family area fiber switching box, respectively, and the family wings to the student dormitories of radiation. The buildings the center of the trunk joint topology total wiring in the buildings, the horizontal portion of the joint topology center line in the distribution between the level of twisted-pair cable from the patch panel leads to the various information points. This will form a three-star three-point management to achieve the integrated wiring in the connection, and configuration flexibility.
Master the characteristics of reasonable Cabling
Taking into account the needs of the campus network applications, cabling system channel stability, reliability, high-capacity special attention. User work area information from the terminal equipment connected to the outlet connection, and various adapters such as the composition of wiring devices, information outlet with D-Link's single-and dual-port products, complete package, with the appropriate flame-retardant properties to ensure Consumer Safety; module 180 design, easy-to-site construction termination; has excellent transmission performance, full support for all voice communications systems, 10Base-T, 16Mb / s, 100Base-T, 155Mb / s and 622 Mb / s ATM , 1000Mb / s, such as high-speed multimedia applications, is a comprehensive end to end cabling solutions.
Subsystem level using D-Link Super unshielded twisted pair for transmitting data, voice and image signals, the data transfer rate can be achieved within 100 meters of 100Mbps, 155Mbps and even the future of 1000Mbps; because all horizontal use the same Category 5 unshielded twisted pair, information export flexibility to change equipment without the impact of transmission medium.
The project's main hub subsystem to the office by the use of outdoor buried 8-core optical fiber, optical fiber distribution cabinet to the family area with outdoor 6-core optical fiber, to the library with 12-core optical fiber, to the student activity center in a 100-core optical fiber; between the two main floor, 4-core optical fiber are used outdoors. Inside the building backbone subsystem provides the building part of the main distribution frame MDF connection with the sub-route. Based system inside the building the trunk with D-Link 6 twisted pair cable to each floor, were among the main wiring connection with the distribution of lines between, rack into the main channel data.
Telecommunications between the subsystems using D-Link's enhanced modular patch panels, patch panel all the standard of all 19 "products, can be placed directly in cabinet. Telecom subsystems are located in the office building, three-story lab building located between a wiring; family wings located in a wiring area of each unit, 1-3 units of young faculty floor area located a wiring, the wiring area based In Unit 2; 4-5 unit located a wiring area; student dormitory shaft at each of the modules inside a wiring closet. Set in the wiring between the 19-inch standard rack, to install the patch panel, fiber patch panels and network equipment, information points on each floor to provide a flexible, safe, clean place of management. In the wiring area based chassis, chassis no patch panels.
Strict supervision and care of details in
Construction of Jiaozuo Institute of Technology campus policy on the actual situation in the design of this wiring scheme, the overall planning, system design, step by step toward strict accordance with the design, elevation, layout, pipe, process checks and so on, all to meet the needs of the school district building and modeling, in the ISO/IEC11801 standard tests such as ultra-acceptance in five categories, all passed. D-Link provides all the cabling product introduction marks a clear classification of packaging, and provide all kinds of practical wire bonding, crimping, stripping / tangent tools greatly facilitate the construction of the network. Groups of the consideration to the actual situation, to meet the network communication transmission Jichu 上, the program Huan do the minute detail, Zuodao wiring neat, nice, everywhere Tixian humanity, for the user Dailai warm 便利.
D-Link products are easy to install cabling, wiring and flexible features, Jiaozuo Institute of Technology Campus by the formation of three joint topology campus, take three management methods, application modular design, all devices are not required to change the opening and change the layout, simply change the application of appropriate equipment and necessary on the patch panel jumpers can effectively protect the initial investment. D-Link wiring system is also related systems and services for future upgrade and expansion of body to provide a broad platform for the backbone network into 1-10G Fast Ethernet, using star topology to achieve good scalability. Makes its own independent network cabling systems can be adapted to a variety of applications, has good compatibility.
In such a standard, stable, open, compatible and high density wiring basis, through the information signal Tigong full Cujin entire complex of structures, systems, service management and internal connection between them is optimized for Jiaozuo Institute of Technology Jianshechengwei an investment in a reasonable, efficient, comfortable and convenient environment to provide favorable support.
