1. OM5 solves the distance limitation of OM3 and OM4 in the data center
OM5 fiber is designed based on VCSEL laser light source, which specifies the bandwidth characteristics for WDM. The purpose of this new fiber classification method is to provide support for a variety of "short" wavelengths between 850nm and 950nm, which are suitable for high bandwidth applications after aggregation. The attenuation of OM5 broadband multimode optical fiber cable is reduced from 3.5 dB / km of OM3 and OM4 to 3.0 dB / km, in addition, the bandwidth requirement on 953nm wavelength is increased. At the same time, it supports the future 400g Ethernet, and has the advantage of transmission distance.
2. OM5 solves the problem of cable explosion caused by large bandwidth and low delay
The geometric size of OM5 fiber (50 μ m core, 125 μ m cladding) is the same as OM3 and OM4, so it can be downward compatible with these types of fiber, and can be smoothly upgraded from 10g to 400g or even higher rate, which ensures the flexibility and scalability of OM5 fiber application; OM5 fiber can support higher speed network transmission with fewer multimode fiber cores, and its cost and power consumption are far lower than that of single-mode fiber. At present, the transmission rate of large data center is constantly increasing. The 100g / 200g / 400g super large data center is under construction and planning. Using the current OM3 / OM4 multimode fiber is bound to form a large number of fiber uplink, which brings great benefits to data center cabling Large pressure will affect the air distribution of the data center and increase the energy consumption of the data center for a long time.
3. OM5 continues the dominant position of multimode fiber in the data center
Strong scalability: OM5 fiber can combine short wavelength division multiplexing (swdm) and parallel transmission technology in the future, and only need 8-core broadband multimode fiber (wbmmf), it can support 200 / 400g Ethernet applications.
Cost reduction: OM5 optical fiber uses the WDM technology of single-mode optical fiber for reference, extends the available wavelength range during network transmission, can support 4 wavelengths on 1-core multimode optical fiber, and reduces the number of optical fiber cores required to the previous 1 / 4, which greatly reduces the network wiring cost.
Strong compatibility and interoperability: OM5 fiber can support traditional applications as OM3 fiber and OM4 fiber, and it is fully compatible with OM3 and OM4 fiber and has strong interoperability.
4. OM5 fiber will be an important choice for data center
Multimode fiber has always been an efficient and flexible transmission medium. It can adapt to higher speed transmission network by continuously developing new application potential of multimode fiber. Multimode fiber with VCSEL has the advantages of low link cost, low power consumption and higher availability, and becomes the most cost-effective data center solution for most enterprise customers. The continuous and stable demand growth of cloud data center and enterprise local data center provides a broad market prospect for cost-effective multimode fiber solutions.
