What affects the data center transmission performance?

Data CenterIt is the core area of data exchange and storage. It provides services for key data operations and has high requirements on system reliability. Generally, users will not hesitate to use high-end product technical solutions, especially for data centers.WiringSystems: With the rapid popularization and continuous development of the Internet, more and more well-known enterprises have built their own data centers. Although enterprises invest a small proportion in the overall wiring system, but it determines the stability requirement of the maximum proportion of data center transmission. Some Problems in the wiring process will affect the entireOptical FiberTo some extent, the performance of the link determines whether the data center can meet the expected standards or the ideal standards originally designed by the owner. These problems are summarized as follows:

Face cleaning

Currently, many construction teams have not cleaned the end face before inserting the jumper, or unplugged the dust cap and plug it in later. This method is inappropriate. Because there is a lot of small dust in the construction environment, which is invisible to the naked eye. To avoid affecting the testing value, it is best to unplug the dust-proof cap and dip the dust-free paper into 90% alcohol for face cleaning. The dust-free paper cannot be replaced by paper towels or cotton balls for cleaning. You can also use advanced equipment for face detection, for example, hand-held probing) optical fiber video magnifiers for face detection or alcohol cleaner.

Improper Construction

Improper construction mainly refers to the improper construction method or accidental damage to network cables during construction. The bending radius of the most important cable is not standardized as required. More and more data centers use high-density distribution frames, which increases the difficulty of construction. In order to better avoid the impact of bending radius on the test value of the entire link, therefore, you must pay attention to the bending radius of the cable during construction. If necessary, perform system installation training before construction.

Construction Environment

The interior decoration process often brings about the dust, you can see that the Cabinet or the floor is covered with a thick layer of dust, in this environment, the infrastructure cabling that has been completed, especially the infrastructure cabling for data centers at all levels, will be a serious challenge. This problem has plagued system integrators and users for a long time. Generally, the IDC room is cleaned before the site construction, so as to prepare for the construction. During construction, we should try our best to wear shoes and covers for construction. We should strictly implement the cleaning and sanitation system and the shoe changing system in and out of the data room.

Bidding for quality issues of connectors or equipment)

Generally, one end of jumper 2 is connected to the Distribution Frame of MDA, and one end is connected to the switch. Any problem at one end will affect the test value of the entire channel. Therefore, during the preliminary bidding, you must confirm that you have the qualification and it is best to let the manufacturer present some qualification certificates, mainly to provide jumpers, third-party certification organizations such as UL and ETL for optical fiber SFP modules and optical fiber distribution frames, and authoritative domestic inspection institutions such as MIIT test reports, the model of the tested product is the same as the model of the bidding product, and the corresponding qualification certificate can be provided. The Integrated Wiring manufacturer selected by the bidder shall have ISO9001 and ISO14001 certification.

Test Instrument Problems and test misoperation

Prior to testing, perform testing and inspection on the instruments and tools required in the project. The testing instrument shall be used within the validity period only after it has been verified by the corresponding metering department and obtained a pass. The accuracy of the testing instrument shall comply with the relevant standards, and the accuracy shall be regularly inspected and calibrated in accordance with the relevant identification procedures and calibration methods. During the test, select the corresponding test standard (method) for testing. For example, you must first check the single-mode or single-mode optical link to avoid misoperation.

Summary

If the Testing Performance of the optical fiber link is too high, I think that as a good integrator or construction team, we must strictly follow the standard standards) to implement the construction, before entering the construction site, it is best to go through the product training of the manufacturer before construction. This not only understands the characteristics of the manufacturer's products, but also reminds integrators or construction teams to pay attention to the points during construction, avoid excessive fiber link testing performance due to construction problems.
