Technical requirements of the cabling system
As generic cabling services accommodate intelligent complexes, it is particularly essential to ensure the network stability, high-performance operation, reduce network error rate and failure rate. The cabling design should provide technology realization methods on the flexible management.
PUCAKC’s generic cabling system meet following technical requirements:
Conform to the newest and most mature international, domestic standards (such as TIA/EIA 568C and ISO/IEC 11801) and new high-bandwidth fiber standards, ensure the high-speed and reliable information transmission of computer network, maintain a high level of flexibility, reliability, integrity and expandability.

Due to the contradiction between long-term usage of generic cabling system and the constant growth of network technology, the generic cabling design provided by PUCAKC fully considers current and future application prospects, ad
opts the modularize system, supports high-speed data transmission, catering to future 10G or 40G Ethernet, ensures downsized compatibility and supports the Ethernet, high-speed Ethernet, token ring network, ATM, FDDI, ISDN and other networks and applications.

• The analysis of network applications
Due to the rapid development of computer network technologies and applications, we can clearly see the law of development of “Moore’ Law” from 10Mbps，100Mbps，1Gbps to 10Gbps. The network operation speed will increase by an average factor of 10 every five year. In face of the change, each user needs to consider the steady operation and fast updating of its network system.
Required by the user’s status quo, the design of PUCAKC is mainly directed to the application of computer network. Currently, 10G mainstay of Ethernet and 100M/1G Ethernet-to-desktop are mainly considered for the practical application of the user; the upgrade mode in the following years will be 40G/100G mainstay of Ethernet and 1G/10G Ethernet-to-desktop.
PUCKAC’s generic cabling system will support the double application of current and future network from the user, any expenses during the update will not be increased to truly realize fast transient mode.

• The analysis of model selection
The generic cabling system is generally composed of six individual subsystem, including working-area subsystem, horizontal subsystem, administration subsystem, backbone subsystem, equipment-room subsystem and cam-pus subsystem. Special transmission technologies consist of twisted-pair and optical fiber.

Currently, the user mainly faces the following issues in actually selecting the model of cabling products:
The selection of copper-cable performance: Cat5e / Cat6 / Cat6A
The selection of copper-cable type: U/UTP / F/UTP / S/FTP
The purpose of the cable: direct burial/tunnel/overhead/interior/exterior/common-use
The structure of the cable: GYTS/GYXTW
Multimode fiber: OM1 62.5μm / OM1 50μm / OM3 50μm / OM4 50μm
Single-mode fiber: OS1 / OS2 ITU-T G.652D
The performance of cable skin: CM antiflaming grade/CMR antiflaming grade/CMP antiflaming grade/LSZH antiflaming
The above issues will finally be divided into three major considerations: transmission performance/reliable information/environmental safety
For loose standards in the generic cabling performance planning, there is a different view upon the application and background of the user. It is crucial to adopt high-performance generic cabling system to maintain free network safety. It includes two sides, one is up to the newest standard requirement, and the second is to be equipped with higher performance beyond the standard. Due to more and stricter cabling requirements provided by Gigabit and above network, the user and more concerned about the high-grade cabling. In fact, the user generally chooses CAT6E cabling or fiber, actual application will be integrated into the intellectualization, data center and other high-end application requirements. The application growth is extremely huge in the future.
Apart form this, people pays much importance on the stability of information communication and environmental safety of products. From a strict perspective, the cabling system must meet three major factors，PUCAKC is always leading the industry on the level.
