With the growing demand for high-bandwidth, high-speed applications in data centers, OM5 fiber optic patch cords have been approved as a new type of multimode fiber (MMF) for high-speed data center applications, and the related OM5 fiber optic patch cords have also attracted a lot of attention in the industry. widespread attention.
OM5 fiber patch cord was originally called broadband multimode fiber patch cord. It is a new standard for fiber patch cord defined by TIA and IEC. The fiber diameter is 50/125μm. Compared with OM3 and OM4 fiber patch cord, OM5 fiber patch cord Can be used for higher bandwidth applications. The optical fiber preform manufacturing process of OM5 optical fiber patch cord has been optimized, so it can support higher bandwidth. In terms of structure, it is no different from OM3 and OM4 fiber optic patch cords, so it is fully backward compatible with traditional OM3 and OM4 multimode fiber optic patch cords. In addition, in February 2017, TIA stipulated that the identification color of OM5 fiber optic patch cords is water green, and OM3 and OM4 fiber optic patch cords can still be used with OM5 fiber optic patch cords, the only difference is that the color of the outer sheath needs to be changed so that Easily identify OM5 connections.
Why use OM5 fiber optic patch cord?
Widely recognized: OM5 fiber optic patch cords were originally issued by the Communications Industry Association as TIA-492AAAE, and were unanimously approved in the ANSI/TIA-568.3-D revision opinion collection issued by the American National Standards Institute;
Strong scalability: OM5 fiber patch cords can combine shortwave 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 Apply to the coming era of 5G Internet of Everything;
Cost reduction: OM5 optical fiber patch cord draws on the wavelength division multiplexing (WDM) technology of single-mode fiber, which extends the available wavelength range for network transmission, and can support 4 wavelengths on 1-core multimode fiber. The number is reduced to 1/4 of the previous one, which greatly reduces the wiring cost of the network;
Strong compatibility and interoperability: OM5 fiber patch cord can support traditional applications like OM3 fiber patch cord and OM4 fiber patch cord, and it is fully compatible with OM3 and OM4 fiber patch cord and has strong interoperability.
The application prospect of OM5 fiber optic patch cord
OM5 fiber optic patch cord gives more vitality to super-large data centers. It breaks through the bottleneck of parallel transmission technology and low transmission rate adopted by traditional multimode fiber, and can not only support higher speed with fewer multimode fiber cores network transmission, and because it uses low-cost short-wavelength wavelengths, the cost and power consumption of optical modules will be much lower than single-mode optical fibers using long-wavelength laser light sources. Therefore, it will have broad application prospects in future 100G/400G/1T ultra-large data centers.
