OM5 Fiber Advatanges

OM5 fiber has the advantage of transmission distance，it supports future 400G Ethernet, for higher speed 400G Ethernet applications such as 400GBase-SR4.2 (4 pairs of fiber 2 wavelengths, each channel uses 50G PAM4) or 400G Base-SR4.4 ((4 pairs of fiber 4 Wavelength, each channel uses 25GNRZ), The attenuation of the OM5 broadband multimode optical cable has been reduced from 3.5 dB / km of the previous OM3 and OM4 optical cables to 3.0 dB / km. In addition, the bandwidth requirement at the wavelength of 953nm has been increased

Strong expandability: OM5 fiber can combine short wave wavelength division multiplexing (SWDM) and parallel transmission technology in the future, and only requires 8-core broadband multimode fiber (WBMMF) to support 200 / 400G Ethernet applications.

Compatibility and interoperability: OM5 fiber can support traditional applications just like OM3 fiber and OM4 fiber, and it is fully compatible with OM3 and OM4 fiber and highly interoperable also can be smoothly upgraded from 10G to 400G or even higher rates

Reduce cost: OM5 fiber is designed based on VCSEL light sources and specifies bandwidth characteristics for wavelength division multiplexing (WDM), it extends the available wavelength range during network transmission, and can support 4 wavelengths on 1 core multimode fiber, reducing the number of fiber cores It is 1/4 of the OM3 or OM4, which greatly reduces the wiring cost of the network.

OM5 fiber increase the baud rate (PAM4) and increase the number of wavelengths to achieve a higher number of multimode fiber cores to support higher-speed network transmission, and the overall cost and power consumption are much lower Single-mode fiber, in the future it should be widely applied in 200G / 400G / 1T and other large data centers.
