OM3 And OM4 Fiber for 10G/40G/100G Network

Introduction to OM3 & OM4 Fiber
OM4 fibres are an improvement on OM3 fibres and, as mentioned above, meet the ISO 11801 standard. The primary focus is on the use of laser-optimized fibers with a 50um core that provide sufficient bandwidth to support up to 10 GBE for a cable length of 550 meters. It also uses 50UM cores and supports a maximum bandwidth of 10GB / s for the fiber-to-cable fiber.

Main Difference Between OM3 And OM4 Fiber
Optical attenuation
The fibres are obvious, but there is a attenuation, and this is caused by the use of a high-power, low-energy and low-frequency laser.

Modal dispersion
As most people know, modal spread is of great importance to bandwidth, and the higher bandwidth available in OM4 means a lower "modal spread," which allows for a more paired connection. This allows information to be transmitted much faster and more accurately than before, even at low frequencies.

OM3 And OM4 Fiber 10G/40G/100G Transmission Distance
Since OM4 is designed for longer distances than OM3 fibers, it can tolerate a higher degree of loss. Depending on the modular capacity, the maximum transmission distance of an OM 4 fiber can be between 400 and 550 m, while the OM 3 fiber may only be 300 m. It may be a more flexible option for a network manager to install an O4 fiber in some cases, but not all.
The difference between OM3 and OM4 transmission distances can be checked in the following table, as well as the maximum transmission distance of the individual OM fiber types.

OM3 And OM4 Fiber Price
OM4 costs are higher than OM3 fibers, but the cost depends to a large extent on the size of the cable, the volume of cable and the bandwidth available to the network. The om4 fibre optic cable is much more narrowly buffered than the om3 cable in terms of transmission distance. This means that the difference in transmission distances between the two types of fibre optic cables is very small, as the volumes of each cable are smaller.

Conclusion
In this article we will focus on the OM3 and OM4 fibers and discuss some of the advantages and disadvantages of these two types of cabling, as well as the advantages of MTP and MPO. Hopefully this article will help you to understand the OM3 and OM4 fibers and to choose the right fiber cable for you. The om3 / om4 multimode fibers provide a cost-effective solution for buildings and corporate campuses.
