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 Fibre 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 bandwith. Workstations, fiber switches and
servers, fiber modems, and similar hardware require duplex cable. 10G
fiber optic patch cables provide 10 gigabit bandwith speeds in high
bandwidth applications 5 times faster than standard 50um fiber cable.
They use both VCSEL laser and LED sources.
FiberStore 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,

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.
