數據中心應該選用OM5好還是OM4好 | |
Which data center should choose OM5 or OM4? Performance: Under the 850nm wavelength, the high-performance OM4 is higher than the effective mode bandwidth of OM5, while in the 880~950 wavelength range, OM5 can provide more effective mode bandwidth. In terms of attenuation and effective mode bandwidth standard definition, OM4 can provide performance parameters consistent with OM5 at 850nm and 1300nm wavelengths. Transmission distance: When OM5 is used with SWDM optical fiber transceiver, it can play a certain transmission distance advantage, but if it is only used for the more common VCSEL (850nm) transceiver in the data center, and the most widely used optical fiber transmission, then OM5 does not There is no distance advantage. Reducing the number of optical fibers: Although the use of WBMMF technology can effectively reduce the amount of optical fibers used in the data center, this is not the credit of OM5, but the natural advantage of SWDM transceiver technology. Price: The price of OM5 fiber is significantly higher than that of OM4. Even if the number of fibers is reduced, the price advantage of OM5 is difficult to show. Product color: TIA defines the color of OM5 products as lime green (Lime), which is indistinguishable from the color of APC products commonly used in data centers, which makes its promotion in data centers very unfavorable. * * * * * * LIV is a professional data center to set up a company, with a group of professional team intimate attention to customer requirements, and provide quality services.
