Optical fiber technology was originally developed for data center applications, and from the current development point of view, it will soon become an ideal choice for building backbone networks.
With the development and application of wireless technology, the horizontal cabling bandwidth in commercial and industrial buildings has exceeded 1Gbps, and the accompanying requirement is that the cabling backbone infrastructure supports at least 40Gbps and 100Gbps speeds. This means that the promotion of high-density applications in data centers is very suitable for the current development and needs. The fiber OM5 broadband can not only support 802.11ac wi-fi systems, but also support high-density 5G wireless networks.

Basics of High Density OM5 Fiber
The ISO and TIA standardization organizations released the latest cabling standards ISO 11801 3rd and TIA-568.0-D respectively in 2017.
OM5 broadband multimode fiber optic cable: The attenuation is reduced from 3.5 dB/km of the previous OM3, OM4 fiber optic cable to 3.0 dB/km, and the bandwidth requirement on the 953nm wavelength is also increased. The geometry of OM5 (50µm core, 125µm cladding) is the same as that of OM3 and OM4, so it is backward compatible with these types of fibers.
OM5 fiber also supports future 400G Ethernet, for higher-speed 400G Ethernet applications such as 400G Base-SR4.2 (4 pairs of fibers with 2 wavelengths, each channel uses 50G PAM4) or 400G Base-SR4.4 ((4 For 4 wavelengths of fiber, 25GNRZ per channel), only 8 cores of OM5 fiber are required. OM5 fiber is a laser-optimized multimode fiber (MMF) with bandwidth characteristics specified for wavelength division multiplexing (WDM). The purpose of this new fiber classification method is to provide support for a variety of "short" wavelengths between 850nm and 950nm, wavelengths in this range suitable for high bandwidth applications after aggregation.
What is the difference between OM5 fiber patch cords and OM3/OM4 fiber patch cords?
1. Outer jacket color: Generally speaking, the outer jacket color of OM3 and OM4 fiber optic patch cords is turquoise or purple, while the outer jacket color of OM5 fiber optic patch cords is aqua.
2. Wavelength: The working wavelength of OM5 fiber jumper is 850/1300nm, and can support at least 4 wavelengths. The usual working wavelengths of OM3 and OM4 are 850nm and 1300nm. In the same wavelength window, the transmission distance of this multimode fiber jumper is also different.
3. Effective Mode Bandwidth (EMB): OM5 fiber jumper has a higher breakthrough in Effective Mode Bandwidth (EMB), which increases the effective Mode Bandwidth (EMB) at 850nm wavelength to 6000MHZ.km, around 880nm wavelength It reaches 8000MHZ.km, which is far more than the traditional OM3 and OM4 multimode fiber patch cords.
What are the advantages of OM5 fiber patch cords?
High degree of recognition: OM5 fiber optic patch cords were originally issued as TIA-492AAAE by the Communications Industry Association, and were unanimously recognized in the ANSI/TIA-568.3-D revision solicitation issued by the American National Standards Institute;
Strong scalability: OM5 fiber patch cables can combine short wavelength wavelength division multiplexing (SWDM) and parallel transmission technology in the future, and only need 8-core broadband multimode fiber (WBMMF) to support 200/400G Ethernet application;
Cost reduction: The OM5 fiber patch cord draws on the wavelength division multiplexing (WDM) technology of single-mode fiber to extend the available wavelength range during network transmission. It can support 4 wavelengths on a 1-core multi-mode fiber. The number is reduced to 1/4 of the previous one, which greatly reduces the wiring cost of the network;
Compatibility and Interoperability: OM5 fiber patch cords can support legacy applications just like OM3 fiber patch cables and OM4 fiber patch cables, and are fully compatible and interoperable with OM3 and OM4 fiber patch cables.
