With the escalation of the Internet industry to develop, servers, switches and other network products, data centers need to accommodate more equipment room, computer room cabling system is not standardized or if it is not serious, then there would be a big risk, a serious restrict the airflow by causing overheating and shut-down phenomenon, so we must pay attention to the data center cabling system equipment room and maintenance problems, then the fiber optic cabling data center room, how do?
Fiber optic cabling data center room, how do?
The use of optical fiber data center room to take into account whether the flexible scalability, the next ten years or twenty years later we must consider whether the cable is capable of carrying Gigabit and even 100G. You choose what level of cable type, it becomes particularly important. Design data center room should fully fiber system cabinets and other equipment to ensure that when arranged in a standard hot and cold aisles, with ample cable connection space, and the upper and lower tracks will not affect the smooth flow of hot and cold air, the wiring system binding site and energy savings is mainly reflected in the design of "cold path" of the room, air in the cold room to complete the isolation channel, so * limits to improve energy efficiency, so as to achieve energy saving.
Data center room cabling method:
1. Cabinet air conditioning wind mouth shall ensure that the gate is open, in order to prevent overheating caused by the phenomenon of death.
2. inside the cabinet each cable label should be maintained so as not to be late cause unnecessary trouble.
3. Switch to use the matching ear fixed on the top of the cabinet to help walk the network cable.
4. Good stickers each server asset number, by the label printer and the printed bar code + number of assets together, each two identical printing device and the front edge of a respective stick.
5. General traces from different directions and the cable from the power line, cable ties tied with each section.
6. The network server is connected to both ends of the rear end of the thread switch to mark the same numbers label ties, and consistent with the number of switch port numbers.
7. To ensure that when the enclosure wire power cord to both ends of the server power connector fixing tie label.
8. The alignment between the cabinet and the cabinet is to be routed from the general direction of the top of the cabinet.
9. If the cabinet is contained outside the network switch, two different colors to make full use of the network cable distinguish between them.
Data center room advantages of optical fiber transmission, optical broadband access as a mainstream way communication with large capacity, long distance relay, confidential performance, adaptable, small size, light weight, and low price of raw materials a wide source of advantages , the application in optical fiber communication systems and more widely.
1, bandwidth: band width representative of the size of the transmission capacity. The higher the frequency of the carrier, the bandwidth of the transmission signal can be greater;
2, low loss: optical transmission 1.31um per kilometer loss 0.35dB or less when the light transmission 1.55um, smaller loss per kilometer, up to 0.2dB or less;
3, light weight: the optical fiber is a glass fiber, a small proportion, it has a small diameter, light weight, very easy to install;
4, anti-interference ability: because the basic components are quartz optical fiber, light transmission only, non-conductive, electromagnetic fields from acting, in which the optical signal transmission is not affected by the electromagnetic field, so that optical transmission of electromagnetic interference, the interference has industrial strong resilience;
5, high fidelity: because optical transmission relay amplification generally do not need, and does not introduce a new nonlinear distortion amplification. As long as the linearity of the laser, the television signal can be transmitted with high fidelity;
6, reliable performance: the system comprises a small number of optical devices (such as amplifiers require dozens unlike cable system), naturally high reliability, combined with the very long life of the fiber optic equipment, time between failures 500,000 ~ 750,000 hours;
7, costs continue to decline: because of the production of the fiber material (quartz) is very rich source, as technology advances, the cost will be further reduced.
