OM1/OM2/OM3/OM4 Fibers

OM1 refers to 50um or 62.5um core diameter multi-mode fiber with a full injection bandwidth of 200/500MHz.km or more; OM2 refers to 850/1300nm full injection bandwidth of 50um or 62.5um core diameter multi-mode fiber above 500/500MHz.km; OM3 is an 850nm laser-optimized 50um core diameter multi-mode fiber, in the 850nm VCSEL 10Gb/s Ethernet, fiber transmission distance can reach 300m; OM4 is an upgrade to OM3 multimode fiber, which can travel up to 550m. Traditional OM1 and OM2 multimode fibers are standard and design based on LED (Light Emitting Diode) mode, while OM3 and OM4 are optimized on the OM2 basis to make them suitable for both LD (Laser) and LED transmission; Compared with OM1 and OM2, OM3 has a higher transmission rate and bandwidth, so it is called optimized multimode fiber or 10Gbps multi-mode fiber; The OM4 is reoptimized on the OM3 for better performance.

OM4 Fiber Advantages

For a typical link, the cost of a light module is approximately expensive. Although the cost of single-mode fiber is cheaper than multi-mode fiber, but the use of single-mode fiber requires a very expensive 1300nm optical module, the cost of which is about 2-3 times that of 850nm multi-mode optical module, in general, the cost of a multi-mode fiber optic system is much lower than the single-mode fiber system. When investing in fiber optic cabling, if you can consider adding some initial investment in cabling and adopting better multimode fibers, such as OM4 fiber, we can ensure that we can make full use of current multimode fiber technology to reduce the overall cost of the current system, and when the system needs to upgrade to higher-rate systems, such as 40G and 100G, The om4 is left to use and will be more cost-effective. In short, when the transmission rate is greater than 1gb/s, multimode fiber is a good system choice.

OM4 Cable Applications

OM4 fiber optic cable is mainly used for 10G, 40G and 100G Ethernet, is the optimized version of OM3 fiber optic cable, so all aspects of performance than OM3 fiber optic cable is stronger, so the rate in the case of 40G or 100G OM4 fiber optic cable is a good choice. For Ethernet users, the transmission distance can be up to 300m to 600m in 10Gb/s transmission, and in 40Gb/s and 100Gb/s system transmissions, the transmission distance can be 100m to 350m. For campus network users, the OM4 fiber optic cable will support 4Gb/s fiber link length 400m, 8Gb/s fiber link length 200m, 16Gb/s fiber link length 130m. OM1 and OM2 have been widely deployed in building-to-building applications for many years, supporting Ethernet road transmission snare with a maximum of 1GB. OM3 and OM4 fiber optic cables are typically used in data center cabling environments, supporting the transmission of 10G or even 40/100G high-speed Ethernet paths.

OM4 Fiber Cables from Professional China Manufacturer

Om4 fiber optic cables are ISO/IEC 11801 approved building levels and backbone fiber optic cable types and are also used for data center horizontal and trunk connections.The OM4 fiber optic cable supports 10GBase-SR to 400 meters, more distance than the OM3 fiber optic cable transmission, and some switches on the market can support up to 550 meters. OM4 fiber optic cable because it can support 40G/100G transmission to 150 meters, 50% more than the OM3 fiber optic cable 100 meters transmission distance, so it is considered to be more suitable as a multi-mode fiber optic cable type to support 40G/100G transmission, using 8 channel transmission 100GBase-SR4 protocol, The OM4 cable can support 100 meters.

The transmission distance between THE OM3 and OM4 fiber jumpers under different rates and interfaces is also different, so combining our own needs, choosing the most suitable fiber jumper is conducive to cost savings and maximizing resource utilization. If you want to know more about connector combinations, Huihongfiber also offers an effective solution for LC, SC, ST, FC and MTP/MPO combinations for OM3 and OM4 fiber jumpers.

In addition, Huihongfiber offers a custom service that allows you to customize the fiber you want. If you need a higher data rate or plan to upgrade your network in the future, a laser optimized OM3 fiber jumper or OM4 fiber jumper would be a reasonable choice. The OM3 fiber has been extensively practiced, and in the future, it can leave more wiggle space in the optical budget. OM4 fiber provides users with a longer-range transmission solution that data centers may need.
