OM3 And OM4 Fiber for 10G/40G/100G Network
Multimode fiber is highly appreciated by Ethernet users, but has gained acceptance in other markets where it offers users the ability to extend connection distances, increase network reliability and reduce costs without centralized electronics.
This passage would give a brief introduction to OM3 and OM4 fibers, list their applications and give an overview of their advantages and disadvantages. The predominance of OM2 fibers is due to the fact that the use of optimized fibers is more efficient and cost-effective - more effective than conventional fibers - up to - the node systems (FTTN). OM5 fiber and the extension of the multimode fiber family with om4 fibers to meet the requirements of long-range applications. With the introduction of the OM1 fiber line in the mid-1990s, the OM 3 fiber was produced at just the right time for the market.
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.
OM3 And OM4 Fiber Selection Guide
The 50 micrometer OM3 fibers are designed for 10 gigabit Ethernet in 300 meters, but the OM4 can accommodate 550 meters.
Therefore, many users are now choosing OM3 and OM4 as the best choice for high-speed, low-cost, high-bandwidth and high-performance Ethernet.
If you need high data rates and plan to improve your network in the near future, the laser-optimized 50-micrometer OM3 and OM4 would be a logical choice. Compared to the OM2 fiber, it is future-proof and enables speeds of up to 10 Mbit / s. According to a recent survey, over 80% of the 50 micrometer fibers sold are either OM 3 or OM 4.
OM4 fibers offer users a transmission solution for long distances and allow more flexibility in their optical budget. Typically, OM3 and OM4 fiber optic cables are used in structured cabling environments. Typical applications could be virtualized, high-speed data centers, large data center applications, or even small - to medium - business applications.
MTP and MPO cables would be a good choice for a wide range of applications, from high-speed data center applications to large data centers. OM3 cabling kit and offers overwhelming benefits in terms of cost, performance, reliability, durability, flexibility and reliability.
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.
