In the data communications segment, the multimode fibers have been divided into four categories – OM1, OM2, OM3 and OM4. Technically, these categories did not define a specific fiber size, but rather their optical channel performance. OM3 optic fiber, which is 50/125 type and with industrial acknowledged Aqua color. OM3 10G fiber enables low cost 10G fiber optic communications over multimode fiber for as long as 500 meters or so.

The revolutionary OM3 50/125 Multimode cable is capable of handling up to 10 Gigabits of throughput. The 10 Gigabit Ethernet cables offer transmission rates up to 10 Gigabits per second using VCSEL light sources and are backwards compatible with existing LED-based 50/125 multimode installations. Featuring Corning and zirconia ceramic ferrules, the 10GB cables offer superior transmission reliability and core alignment with minimal attenuation. The 10 Gigabit duplex multimode 50/125 cables are ideal for systems in local area networks (LAN), metropolitan area networks (MAN), regional area networks (RAN) and wide area networks (WAN).

The success of the OM3 fiber has enabled the cost effective implementation of many of today's highest speed networks. Today, OM3 is the minimum performance required in data center standards even though it was unheard of 10 years ago. OM4 fiber has been introduced to the market since 2005, sold as premium OM3 or OM3+ fiber. The OM4 designation standardizes the nomenclature across all manufacturers so that the customer gets a clearer idea of the product that they are buying. OM4 is completely backwards compatible with OM3 fiber and shares the same distinctive aqua jacket. OM4 was developed specifically for VSCEL laser transmission and allows 10 Gig / second link distances of up to 550 meters (compared to 300M with OM3).

The basic factors to consider when making a fibre optic cable choice are bandwidth, reach, and cost.
a.High-bandwidth fiber media allows longer-length channels, higher loss-budget margin, and greater design flexibility.
b.Reach or length is a site-specific physical parameter that can be used to immediately narrow your fiber options. In general, as the data rate goes up, the reach goes down. Once reach is established, you can narrow your fiber options by identifying your users' current and/or future bandwidth needs.
c.Cost is the final factor to consider. If you need high speed over short distances, you may be able to use less expensive grades of fiber (OM2 or OM3) across certain links and still achieve reliable 10-Gbit/sec transmission. But if your goal is to build scalability and longer life into the network, it makes more sense to invest in higher-price, high-bandwidth fiber (OM3 or OM4) across the backbone and other permanent links.

FiberStore supplies a full line of multimode fibre optic cables, including OM1 fiber, OM2 fiber, OM3 fiber, OM4 fiber. 10G OM3 and OM4 fiber cables are both utilized for 10Gigabit Ethernet applications. Since OM3 fiber pricing is lower than OM4, I recommend you the cost effective OM3 fiber, lower price but almost same high performance. Also plastic optic fiber or POF Fiber maybe is another good ideal for your telecommunication, POF Fiber is easy to run along skirting boards, under carpets and around tight corners. Our multimode fiber cables are various types including different connector types, cable structure and cable length, all manufactured according to industrial standards and they feature the good price and reliable quality.
