![]() And it’s able to run 40/100GB up to 150 meters utilizing a MPO connector. OM4 was developed specifically for VSCEL laser transmission and allows 10 Gig/s link distances of up to 550m compared to 300M with OM3. OM4 fiber is completely backwards compatible with OM3 fiber and shares the same distinctive aqua jacket. Besides, OM3 is able to support 40 Gigabit and 100 Gigabit Ethernet up to 100 meters, however, 10 Gigabit Ethernet is most commonly used. OM3 supports 10 Gigabit Ethernet at lengths up to 300 meters. Like the OM2, its core size is 50 µm, but the cable is optimized for laser based equipment. OM3 fiber comes with an aqua color jacket. It supports up to 10 Gigabit Ethernet at lengths up to 82 meters but is more commonly used for 1 Gigabit Ethernet applications. Likewise, OM2 fiber also comes with an orange jacket and uses a LED light source but with a smaller core size of 50 µm. ![]() This type commonly uses a LED light source. It is most commonly used for 100 Megabit Ethernet applications. It can support 10 Gigabit Ethernet at lengths of up to 33 meters. OM1 fiber typically comes with an orange jacket and have a core size of 62.5 µm. It can transmit farther at lower data rates, such as going about 2km at 100Mb/s. The maximum transmission distance for MMF cable is around 550m at the speed of 10Git/s. Because of this, more data can pass through the multimode fiber core at a given time. Multimode fiber optic cable has a larger core, typically 50 or 62.5 microns that enables multiple light modes to be propagated. Multimode fiber (MMF) is a kind of optical fiber mostly used in communication over short distances, for example, inside a building or for the campus. OM1 vs OM2 vs OM3 vs OM4 vs OM5, which to choose? You may get answer in this article. With so many options, it can be tough to select the most suitable multimode fiber. There are several kinds of multimode fiber types available for high-speed network installations, and each with a different reach and data-rate capability. So, the best way to tell the two connectors apart?… Keep them in their original packaging until ready for use.Multimode fiber is a common choice to achieve 10 Gbit/s speed over distances required by LAN enterprise and data center applications. The difference is very small, but can make a large impact on insertion loss if the larger multimode ferrule is used on singlemode fiber. A standard singlemode zirconia ferrule will usually have a ferrule hole of about 126 microns, while standard multimode ferrules will be closer to 127-128 microns. The size of the hole in the center of the ferrule will determine the correct fiber type that the connector is designed for. Singlemode connectors will almost always have a zironia (ceramic) ferrule while multimode connectors can have stainless steel (Nickel-Silver), composite (plasitc), or zirconia. A singlemode boot is generally blue or white, while multimode boots are normally black or beige.īut, the main difference is in the ferrule of the connector. The first and most obvious would be the color of the strain relief boot. In general, there are two main differences between singlemode and multimode connectors.
