Laser Optimized Multimode Fiber (OM3) Fiber Patch Cable
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

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.
