What are the advantages of OM5 fiber patch cord?
“OM” is abbreviated for optical multimode, and it is specified by the ISO/IEC
11801 international standard. Currently, TIA and IEC defined fiber patch cord
standards are OM1, OM2, OM3, OM4, and OM5.
What are single-mode and multi-mode? There are two different kinds of
optical fiber cables, single-mode(OS) and multimode(OM). Single-Mode
Fiber is an optical fiber that allows only one mode of transmission. The
core diameter is about 8 to 9μm and the outer diameter is about 125μm.
Multimode Optical Fiber allows different modes of light to be
transmitted over a single fiber with a core diameter of 50μm and 62.5μ
m. Generally, single-mode fiber supports longer transmission distances
than multi-mode fiber. In 100Mbps Ethernet to 1G Gigabit, single-mode
fiber can support transmission distances over 5000m. Multimode fiber is
only suitable for a medium and short distance and small capacity fiber
optic
communication
systems.

What is the difference between OM1, OM2, OM3, OM4, OM5?
In general, OM1 is conventional 62.5/125 μ m; OM2 is conventional
50/125 μ m; OM3 is 850nm laser-optimized 50 μ m core multimode fiber,
and in 10Gb/s Ethernet with 850nm VCSEL, the fiber transmission
distance can reach 300m; OM4 is an upgraded version of OM3. OM4
multimode fiber optimizes the differential mode delay (DMD) generated
by OM3 multimode fiber during high-speed transmission. Therefore, the
transmission distance is greatly improved, and the fiber transmission
distance can reach 550m; OM5 is a new standard for fiber patch cords
defined by TIA and IEC with a fiber diameter of 50/125μm. Compared to
OM3 and OM4 fiber patch cords, OM5 fiber patch cords can be used for
higher bandwidth applications. The bandwidth and maximum distance
are different for different levels of transmission.
What is OM5 fiber?
OM5, previously known as wideband multimode fiber or WBMMF. Known
as Wideband Multimode Fiber Patch Cable (WBMMF), OM5 fiber is a
laser-optimized multimode fiber (MMF) designed to specify bandwidth
characteristics for wavelength division multiplexing (WDM). The new
fiber classification method is designed to support a variety of "short"
wavelengths between 850 nm and 950 nm, which are suitable for high
bandwidth applications after polymerization. The OM3 and OM4 are
designed primarily to support a single wavelength of 850 nm.
The difference from OM3, OM4?
Jacket Color
OM1 and OM2 cable typically come with an orange jacket. OM3 and
OM4 have a suggested jacket color of aqua. The color of the OM5 fiber
jacket was chosen as lime green.
Different application scopes
OM1 and OM2 have been widely deployed in buildings for many years,
supporting Ethernet transmissions up to 1GB. OM3 and OM4 cables are
commonly used in data center cabling environments, supporting 10G or
even 40/100G Fast Ethernet. Designed for 40Gb/s and 100Gb/s
transmission, the OM5 reduces the number of fibers that can be
transmitted at high speeds.

OM5 multimode fiber features
Fewer fibers support higher bandwidth applications
The OM5 fiber patch cord has an operating wavelength of 850/1300 nm
and can support at least 4 wavelengths. The typical operating
wavelengths of OM3 and OM4 are 850 nm and 1300 nm. That is to say,
the traditional OM1, OM2, OM3, and OM4 multimode fibers have only
one channel, while the OM5 has four channels, and the transmission
capacity is increased by four times. Combining short-wavelength
division multiplexing (SWDM) and parallel transmission technology, OM5
only requires 8-core wideband multimode fiber (WBMMF), which can
support 200/400G Ethernet applications, greatly reducing the number of
fiber cores. The cabling costs of the network are reduced.
Longer transmission distance
The transmission distance of OM5 fiber is longer than that of OM3 and
OM4. The OM4 fiber is designed to support a length of at least 100
meters with a 100G-SWDM4 transceiver. But OM5 fiber can support up
to 150 meters in length with the same transceiver.

Lower fiber loss
The attenuation of the OM5 broadband multimode cable has been
reduced from 3.5dB/km for the previous OM3, OM4 cable to 3.0dB/km,
and the bandwidth requirement of 953 nm wavelength has been
increased.
OM5 has the same fiber size as OM3 and OM4, which means it is fully
compatible with OM3 and OM4. The existing cabling network does not
need to be changed to apply to OM5. OM5 fiber is more scalable and
flexible, which can support higher-speed network transmission with
fewer multimode fiber cores. The cost and power consumption are much
lower than single-mode fiber. Therefore, it will be widely used in
100G/400G/1T ultra-large data centers in the future.
