OM means optical multi-mode. Multi-mode optical fiber is a kind of optical fiber mostly employed for communication over short distances, such as inside a building or on the campus. Multi-mode fibers are described using a system of classification determined by the ISO 11801 standard as OM1, OM2, and OM3, which is in line with the modal bandwidth of the multi-mode fiber. Here are the meanings of these: 62.5/125um multimode fiber (OM1), 50/125um multimode fiber (OM2), and laser optimized 50/125um multimode fiber (OM3). This article is mainly about OM3, rapid for OM3 fiber patch cable.
Laser Optimized Multimode Fiber (OM3) has been around since 1999. It supports 300-meter link lengths for 10 Gb/s applications and it is tested to ensure a 2,000 MHz-km Effective Modal Bandwidth (EMB). Its industry-standard 50um core size couples sufficient power from LED sources to support legacy applications like Ethernet, Token Ring, FDDI, and Fast Ethernet for virtually all in-building networks and many campus networks. The 50um core size is also directly suitable for laser-based applications like Gigabit Ethernet and Fiber Channel, etc. Furthermore, it’s the recommended multimode fiber type in ANSI/EIA/TIA-942, Telecommunications Infrastructure Standard for Data Centers.
OM3 fiber is really a logical and cost-effective option for short-range applications that need to support 1Gb/s or multi-gigabit speeds, especially when the cabling component costs take into account under three percent of the total spend. Compared to the total installation price of networks using lower bandwidth OM1 or OM2 fibers, the premium for OM3 fiber is typically about one percent but can offer significant financial savings for that electronics when upgrading to raised speeds, e.g. 10 Gb/s. 10G OM3 Duplex fiber optic patch cord cable includes two fibers, usually in a zip cord (side-by-side) style. We use duplex multimode or single mode fiber optic cable for applications that need simultaneous, bi-directional bandwidth. Workstations, fiber switches and servers, fiber modems, and similar hardware require duplex cable. 10G fiber optic patch cables provide 10 gigabit bandwidth speeds in high bandwidth applications 5 times faster than standard 50um fiber cable. They use both VCSEL laser and LED sources.
fiber-mart.com has all lengths and connectors available. Duplex or simplex 10G fiber optic patch cables are available at good price and fast shipping, for instance, 50/125 sc-sc duplex OM3. And there’s a different type of OM3 fiber patch cable called MPO. The MPO cable is designs for Data Center Applications. It’s a round cable using the outer diameter of three,0 mm or 4,5 mm. The connectors where this cable is terminated on is called MPO/MTP connector. To have a look, please click this link, 10G OM3 MPO Fiber Optic Cable.
Today 1Gb/s-ready backbone solutions would be the norm and provide 10x speed capability at almost cost parity of 100 Mb/s LED-based systems. OM3 fiber has a significantly higher bandwidth advantage for extended reach 1 Gb/s and 10 Gb/s applications that most customers will use today or in the long run, while preserving the reduced system cost advantages of multimode fiber.
In addition, OM3 fiber shares exactly the same connector technologies and installation techniques as 62.5um fiber, which means installers can leverage their existing fiber installation experience without additional training. All of this, coupled with the fact that greatly improved cabling materials and procedures make 50um fiber cable-friendly, is driving the migration to OM3 because the multimode fiber of choice in LANs, SANs, data center interconnects and, now, Access applications. Because of these factors, the Fiber Optics LAN Section recommends that for new installations, customers install OM3 fiber.
