OM5 Fiber Optic Patch Cord: A New Solution for High-Speed Data Center Cabling

What is an OM5 Fiber Optic Patch Cord?

A fiber optic patch cord is a jumper cable used to connect devices to fiber optic cabling links. It features a thicker protective layer and is typically used for connections between optical transmitters and receivers and terminal boxes. It is applied in various fields such as fiber-optic communication systems, fiber-optic access networks, fiber-optic data transmission, and local area networks. As data centers continue to demand higher transmission rates, OM5 fiber optic patch cords have begun to gain increasing usage.

 

Initially, the OM5 fiber optic patch cord was known as Wideband Multimode Fiber (WBMMF), a new standard for fiber optic patch cords defined by TIA and IEC with a fiber diameter of 50/125μm. Compared to previous OM3 and OM4 fiber optic patch cords, the OM5 fiber optic patch cord can be used for higher bandwidth applications. Thanks to significant improvements in the manufacturing process of OM5 fiber preforms, it can support even higher bandwidths.

Structurally, it does not differ significantly from OM3 and OM4 fiber optic patch cords, making it fully backward compatible with traditional OM3 and OM4 multimode fiber optic patch cords. In February 2017, TIA officially designated the identification color of the OM5 fiber optic patch cord as aqua green, while the outer jackets of OM3 and OM4 fiber optic patch cords are lake blue and purple, respectively. OM3 and OM4 fiber optic patch cords can still be used in conjunction with OM5 fiber optic patch cords, with the only difference being the color of the outer jacket, which allows for easy identification of OM5 connections.

 

 
 
 
Three Core Advantages of OM5 Fiber Optic Patch Cord

The OM5 fiber optic patch cord boasts three major core advantages. Firstly, its prime advantage lies in its exceptional scalability. The OM5 fiber optic patch cord can combine short-wavelength division multiplexing (SWDM) with parallel transmission technology, supporting 200/400G Ethernet applications with just 8 cores of wideband multimode fiber (WBMMF), demonstrating immense potential for future applications.

 

Secondly, the use of OM5 fiber optic patch cord effectively reduces construction and operational costs. By leveraging wavelength division multiplexing (WDM) technology from single-mode fiber, the OM5 fiber optic patch cord extends the available wavelength range for network transmission, supporting four wavelengths on a single multimode fiber core. This significantly reduces the number of fiber cores required to one-quarter of the previous amount, greatly reducing the cost of network cabling and serving as one of the fundamental reasons for its widespread acceptance.

 

Thirdly, the OM5 fiber optic patch cord excels in compatibility and interoperability, supporting traditional applications as well as OM3 and OM4 fiber optic patch cords. Furthermore, it is fully compatible with traditional OM3 and OM4 fiber optic patch cords, exhibiting strong interoperability between them.

Meeting High-Speed Data Center Transmission Needs

The OM5 fiber optic patch cord breathes new life into super-large data centers, breaking through the bottlenecks of traditional parallel transmission technology and low transmission rates used by multimode fibers. It not only supports higher-speed network transmission with fewer multimode fiber cores, but also utilizes lower-cost short-wavelengths, resulting in significantly lower costs and power consumption for optical modules compared to single-mode fibers that use long-wave laser sources. Therefore, as the demand for higher transmission rates continues to increase, the OM5 fiber optic patch cord will have a broad application prospect in future 100G/400G/1T super-large data centers.

 

Take the future first-generation 400G Ethernet fiber optic cabling as an example. A total of 16 fiber cores are needed for transmitting signals and another 16 for receiving signals, totaling 32 fiber cores of multimode fiber. This means that data centers need to deploy cabling systems with 32-core MPO/MTP interfaces. Consequently, the high cabling costs will undoubtedly bring tremendous pressure to data center operators.

 

If the OM5 fiber optic patch cord and short-wavelength division multiplexing optical modules are adopted, only 8 cores of multimode fiber are required in total, with 4 cores for transmitting signals and another 4 cores for receiving signals. Each fiber can transmit 4 wavelengths, with a transmission rate of 25Gbps per wavelength. Therefore, each fiber core of the OM5 fiber optic patch cord can transmit 100Gbps of data. By adopting this technology of short-wavelength division multiplexing and parallel transmission, the cabling costs of data centers will be greatly reduced. It is believed that the OM5 fiber optic patch cord will be widely used in the near future.
