What are OM1, OM2, OM3 and OM4?

FacebookTwitterGoogle+LinkedInRedditTumblrShare

There are different types of fiber optic cable. Some types are single-mode, and some types are multi-mode. Multi-mode fibers are described by their core and cladding diameters. Usually the diameter of the multi-mode fiber is either 50/125 µm or 62.5/125 µm. At present, there are four kinds of multi-mode fibers: OM1, OM2, OM3 and OM4. The letters “OM” stand for optical multi-mode. Each type of them has different characteristics.

Standard

Each “OM” has a minimum Modal Bandwidth (MBW) requirement. OM1, OM2, and OM3 are determined by the ISO 11801 standard, which is based on the modal bandwidth of the multi-mode fiber. In August of 2009, TIA/EIA approved and released 492AAAD, which defines the performance criteria for OM4. While they developed the original “OM” designations, IEC has not yet released an approved equivalent standard that will eventually be documented as fiber type A1a.3 in IEC 60793-2-10.

Specifications

  • OM1 cable typically comes with an orange jacket and has a core size of 62.5 micrometers (µm). It can support 10 Gigabit Ethernet at lengths up 33 meters. It is most commonly used for 100 Megabit Ethernet applications.
  • OM2 also has a suggested jacket color of orange. Its core size is 50µm instead of 62.5µm. It supports 10 Gigabit Ethernet at lengths up to 82 meters but is more commonly used for 1 Gigabit Ethernet applications.
  • OM3 has a suggested jacket color of aqua. Like OM2, its core size is 50µm. OM3 supports 10 Gigabit Ethernet at lengths up to 300 meters. Besides OM3 is able to support 40 Gigabit and 100 Gigabit Ethernet up to 100 meters. 10 Gigabit Ethernet is its most common use.
  • OM4 also has a suggested jacket color of aqua. It is a further improvement to OM3. It also uses a 50µm core but it supports 10 Gigabit Ethernet at lengths up 550 meters and it supports 100 Gigabit Ethernet at lengths up to 150 meters.

OM1, OM2, OM3 and OM4 multi-mode fiber

Differences

There are several differences between four kinds of multi-mode fiber, and we can see them clearly from the table below:
OM1, OM2, OM3 and OM4 multi-mode fiber

  • Diameter: The core diameter of OM1 is 62.5 µm , however, core diameter of the OM2, OM3 and OM4 is 50 µm.
  • Jacket Color: OM1 and OM2 MMF are generally defined by an orange jacket. OM3 and OM4 are usually defined with an aqua jacket.
  • Optical Source: OM1 and OM2 commonly use LED light source. However, OM3 and OM4 usually use 850 nm VCSELs.
  • Bandwidth: At 850 nm the minimal modal bandwidth of OM1 is 200MHz*km, of OM2 is 500MHz*km, of OM3 is 2000MHz*km, of OM4 is 4700MHz*km.

OM3&OM4 are Superior to OM1&OM2

10G OM3Both OM1 and OM2 work with LED based equipment that can send hundreds of modes of light down the cable, while OM3 and OM4 are optimized for laser (eg. VCSEL) based equipment that uses fewer modes of light. LEDs can not be turned on/off fast enough to support higher bandwidth applications, while VCSELs are capable of modulation over 10 Gbit/s and are used in many high speed networks. For this reason, OM3 and OM4 are the only multi-mode fibers included in the 40G and 100G Ethernet standard. Now OM1 and OM2 are usually used for 1G which are not suitable for today’s higher-speed networks. OM3 and OM4 are used for 10G mostly at present. But in the future, since OM3 and OM4 can support the 40G and 100G, which may make them the tendency.

OM3 OR OM4 Cable Which One Do You Need

Many types of fiber optic cable in the online company supply.It has many choices in the internet.How to choose the right fiber optic cables if you needed? Such as the OM3 multimode fiber OR OM4 multimode fiber.The first we must know fiber optic cable specifications,and  know their different,and finally to determine which one is the most suitable.

10G Ethernet:

The 10G Ethernet basic power budget is about 6dB but this is degraded for longer link lengths due to signal distortions such as modal dispersion. These distortions mean that the detector requires more power to operate. The way this extra power is accommodated in channel planning is through a “power penalty”. In our example, the power penalty increases from 0 to almost 5dB for the maximum channel length. The penalty is not linear and increases dramatically as the maximum length is reached. In designing the channel, a key factor is the power budget available for connection loss. This is the total power budget inclusive of penalties reduced by the cable attenuation, leaving that portion of the power budget that may be used to cover connector insertion loss, splice loss, bend loss and contamination.The table opposite shows that at 300m with OM3 the loss available for all connections is only 1.79dB. On the other end OM4 allows up to 4.55dB, an increase of 2.76dB. A typical data centre channel may have eight connections. For OM3, the average loss must be less than 0.24dB,including all factors which means premium terminations must be used and there is no margin for installation faults, pinched cables or any other channel problem With a budget of 0.57dB per connection, OM4 allows considerable headroom to support a stable network. Know more OM3 and OM4 in this blog ,it can help you to choose the best cable in your project.

OM3 multimode fiber:

OM3 10G fiber optic cables which are used for 10Gigabit Ethernet applications. These cables are also called multimode OM3 10G Aqua fiber optic cables. Our OM3 10G cables are various types including different connector types, cable structure and cable length. Our OM3 multimode fiber that are compliant to ISO/IEC 11801 standards. These cables are used for 10Gbps networks to meet the requirement of continuous growing of high data rates.Typically 10 Gigabit applications are run on 9/125 Single Mode fiber, which require costly single mode transceivers. By utilizing the FOB501B series cables, you can implement low cost multimode transceivers or VCSEL’s (Vertical Cavity Surface Emitting Lasers) resulting in greater overall system cost savings.

OM4 multimode fiber:

OM4 is the latest high modal bandwidth high performance 50/125 Graded Index Multimode (GIMM) cabled fibre specification. OM4 fibre enables extended range performance over high bit rate links such as 8 Gigabit Fibre Channel and 10 Gigabit Ethernet compared to existing fibre types. FiberStore offer a wide range of OM4 compliant cable assembly products in both standard OM4 and Reduced Bend Sensitivity (RBS) OM4 variants.

What is the difference between OM3 and OM4 fiber?

First, OM stands for optical multi-mode. Both OM3 an OM4 are  50/125 core fiber but they have different internal construction that allows the OM4 fiber to provide the same performance as OM3 but for longer distances. The reason for this is the difference in bandwidth, OM3 has 2500 megahertz bandwidth , OM4 has 4700 megahertz bandwidth. What this translates to is longer transmission distances for the OM4 fiber. So you will need to know the distance of the fiber run in order to help decide which kind of fiber and fiber accessories need to be used.

OTHER INFO: Which optical fiber should I choose, 50 micron or 62.5 micron?

Although 62.5 micron fiber was the most popular only a few years ago, 50 micron quickly gained market share and is continuing to do so. 50 micron fiber can have up to 20 times the bandwidth (data throughput capacity) of 62.5 micron. For identification purposes, multimode fiber, and also singlemode fiber, is often referred to by its performance level identified by ISO/IEC (International Organization of Standards and International Electrotechnical Committee), which is based on the fibers bandwidth capabilities. 62.5 micron multimode is referred to as OM1. 50 micron fiber is referred to as OM2, OM3 and the recently added OM4. As you would imagine, OM4 has greater bandwidth than OM3 and OM3 has greater bandwidth than OM2.

Fifty micron OM3 fiber is designed to accommodate 10 Gigabit Ethernet up to 300 meters, and OM4 can accommodate it up to 550 meters. Therefore, many users are now choosing OM3 and OM4 over the other glass types. In fact, nearly 80% of 50 micron fiber sold is OM3 or OM4.

If you require higher data rates or plan on upgrading your network in the near future, laser optimized 50 micron (OM3 or OM4) would be the logical choice.

Duplex Fiber Among Fiber Optic Cables

Duplex Fiber Cable

Duplex fiber cable is designed for general fiber patch cord production where consistency and uniformity are vital for fast, efficient terminations. We have the right duplex fiber cable in many different outside diameter (OD) sizes and meet all tooling and termination requirements.Duplex Fiber Optic Cables consist of two fibers joined by a thin connection between the two jackets. Workstations, fiber switches and servers, fiber optic modems, and similar hardware require duplex cable. They are used in applications where data needs to be transferred bi-directionally. One fiber transmits data one direction; the other fiber transmits data in the opposite direction. Duplex fiber optic cables from FiberStore can be available in single-mode and multimode.

Multimode vs Singlemode Fiber

A “mode” in Fiber Optic cable refers to the path in which light travels. Multimode cables have a larger core diameter than that of singlemode cables. This larger core diameter allows multiple pathways and several wavelengths of light to be transmitted. Singlemode Duplex cables and Singlemode Simplex cables have a smaller core diameter and only allow a single wavelength and pathway for light to travel. Multimode fiber is commonly used in patch cable applications such as fiber to the desktop or patch panel to equipment. Multimode fiber is available in two sizes, 50 micron and 62.5 micron. Singlemode fiber is typically used in network connections over long lengths and is available in a core diameter of 9 microns (8.3 microns to be exact). Many types of multimode fiber optic cable (such as om3 multimode fiber) and singlemode fiber optic cable for sale in FiberStore.

How Fiber Optic Cables Work

The traditional method of data transmission over copper cables is accomplished by transmitting electrons over a copper conductor. Fiber Optic cables transmit a digital signal via pulses of light through a very thin strand of glass. Fiber strands (the core of the fiber optic cable) are extremely thin, no thicker than a human hair. The core is surrounded by a cladding which reflects the light back into the core and eliminates light from escaping the cable.

A fiber optic chain works in the following manner. At the one end, the fiber cable is connected to a transmitter. The transmitter converts electronic pulses into light pulses and sends the optical signal through the fiber cable. At the other end, the fiber cable is plugged into a receiver which decodes the optical signal back into digital pulses.

Advantages & Disadvantages of Fiber Optic Cable

There are many advantages and disadvantages in using fiber optic cable instead of copper cable. One advantage is that fiber cables support longer cable runs than copper. In addition, data is transmitted at greater speeds and higher bandwidths than over copper cables.
The major disadvantages of fiber optic cables are cost and durability. Fiber cables are more expensive than copper cables and much more delicate.

Three Steps To Pick Out A Fiber Optic Cable
So when you go to pick out a fiber optic cable, there are a few things you’ll want to know. First, make sure that the type of connector you purchase matches your input connection. Second, check to see if your device prefers single or multi-mode transfer. Figure out if you need simplex fiber optic cable or duplex fiber optic cable. And finally, choose which length you need. You can discern this by setting up your system and running a string from the speaker or TV to the equipment. Always buy the next larger length rather than one that is on the small side. You won’t regret it!
