AI computing and hyper-scale data centers are rapidly evolving toward 400G, 800G, and even 1.6T speeds. High-speed optical modules are susceptible to temperature-induced wavelength shifts, while traditional multi-mode fiber suffers from insufficient bandwidth and reduced link margin—issues that have become critical bottlenecks for transmission performance and deployment.

As a global leader in optical fiber and cable technology, FiberHome breaks through these constraints with innovation, unveiling its Next-Generation OM4 PRO and OM5 multi-mode fiber. These precision solutions to overcome bandwidth and high-speed compatibility bottlenecks, significantly reducing data center interconnection costs and upgrade complexity and serves as the core foundation as high-speed interconnects in AI data centers. Notably, under the auspices of the International Photonic Electronics Committee (IPEC), FiberHome successfully completed direct-transmission experiments for 400G eSR4 over 150 meters and 400G eSR8 over 200 meters using OM4 PRO multi-mode fiber. This establishes an industry benchmark for high-speed multi-mode fiber applications in AI data centers and positions FiberHome as one of only two domestic vendors to achieve this validation.

OM4 PRO Multi-mode Fiber: The Top Choice for 400G/800G Upgrades, Delivering Stability, Efficiency, and Quality Enhancement

OM4 PRO multi-mode fiber leverages its wide operating bandwidth of 850–870 nm as a key advantage, delivering comprehensive improvements in bandwidth performance and ensuring consistency across the entire spectrum. This effectively mitigates signal degradation caused by wavelength shifts in optical modules and offers significantly enhanced compatibility compared to traditional OM4 multi-mode fiber.

The fiber supports single-wavelength transmission distances up to 150 m at 100G per wavelength with low bending loss, it is ideal for high-density cabling in data centers while significantly enhancing deployment flexibility. Furthermore, it’s also fully compatible with traditional OM4 multi-mode fiber systems, enabling data centers to seamlessly migrate to 400G/800G systems at a lower cost.

OM5 Multi-mode Fiber: Pioneering the 1.6 T/s Future with Forward-Looking Ultra-High-Speed Interconnects

OM5 multi-mode fiber represents a further advancement over OM4 PRO multi-mode fiber, expanding the operating wavelength range to 850–950 nm and providing native support for Short-Wavelength Division Multiplexing (SWDM) technology. By leveraging the core advantage of parallel multi-wavelength transmission, OM5 delivers dual improvements in single-fiber capacity and link efficiency, providing a more forward-looking evolutionary path for 800G/1.6T or larger data center interconnects.

While maintaining compatibility compared with OM4 fiber series and meeting multi-wavelength transmission requirements, OM5 multi-mode fiber provides greater scalability for data centers. It’s designed for scenarios with long-term demand for ultra-high-speed, high-density transmission—such as hyper-scale AI computing centers and cloud data centers—and serves as the core foundation for future data center upgrades to 1.6T.

Upgrades in AI computing power are accelerating innovation in optical interconnect technology. FiberHome remains steadfast in its core technological road map of "wide-spectrum bandwidth + low loss + high compatibility." By deploying scalable, field-ready wide-bandwidth solutions based on its OM4 PRO and OM5 multi-mode fiber portfolios, FiberHome provides robust support for the full-speed evolution of AI data centers, laying a solid foundation for optical transmission in the era of computing power.
