Summary：
The data center room wiring system is composed of two parts: SAN network wiring system and network cabling system. In computer systems engineering, must respect the room within the wiring of unified planning and design, wiring bridge routing must be integrated into the engine room and other kinds of pipeline, bridge, in order to ensure the implementation of the system is reasonable and orderly room. Data center cabling engineering with its flexibility, scalability to achieve redundant wiring management, the entire structured cabling system should be a comprehensive solution to avoid the emergence of a single point of failure.
Is adopted: plug and play, high density, scalable, pre terminated cable system solutions, modular system management and pre termination assembly can reduce installation time, realize the data center fiber network faster moving, add and change. The system can be used in a wide range of optical fiber products can be used in low loss optical fiber connector and bend insensitive fiber (bending radius 7.5mm), to achieve a smaller backbone optical fiber attenuation and bending performance.
Advantage:
You can quickly respond to mobile, increase and change any network:
In the main distribution area of the data center, the centralized distribution and the star network wiring method are adopted, which is easy to change the wiring of the data device on the panel, and realizes the perfect integration of the physical layer and the application layer in the main distribution area.
Please save the wiring space and installation time:
Practice has proved that the use of high density optical fiber wiring system, compared with the traditional wiring system, can reduce the routing of large congestion in the cable, saving more than half of the space. The high density MPO backbone fiber optic cable is simplified by the factory, which simplifies the network deployment and saves the installation time of the traditional optical fiber 80%.
The support network application in the future:
Using high bandwidth laser (OM3, OM4) optimization of 50/125um optical fiber network, provides a broad space for the treatment of high rate applications, capable of transmitting signal and flexible serial parallel signal, parallel optical fiber technology such as high-speed Internet, Ethernet and 40G/100G are currently in use and implementation of MPO system based on the main cable.
