MultiCom® High-bandwidth OM4 optical fiber
Product Introduction
High-Bandwidth OM4 Optical Fiber, a high-performance multimode fiber, is engineered for rapid data transmission with superior bandwidth and performance. It achieves an effective modal bandwidth of over 2000MHz·km at 850nm wavelength, surpassing traditional fibers, enabling longer distances and higher data rates. Suitable for both intra-data center connections and inter-data center links, its optimized geometry and low attenuation ensure stable signal transmission.
Product Advantages
Super Wide Bandwidth
High-Bandwidth OM4 Optical Fiber boasts a bandwidth of up to 4700 MHz·km, significantly outperforming OM3 fiber's 2000 MHz·km. This provides a broader channel for data transmission. The increase means OM4 fiber can transmit more data in the same time, greatly enhancing network transmission efficiency.
Long-Distance Transmission
In 10 Gbps applications, OM4 fiber can transmit over 550 meters, far exceeding OM3 fiber's range of 300-550 meters. In higher-speed 40 Gbps and 100 Gbps applications, OM4 fiber maintains a transmission distance of 150-300 meters, meeting long-distance data transmission needs. This feature reduces fiber optic cabling complexity and lowers installation costs. Especially in large data centers and enterprise networks, OM4 fiber's long-distance transmission capability significantly cuts fiber laying and management expenses.
Low Loss Characteristics
OM4 fiber exhibits extremely low loss characteristics, effectively reducing signal attenuation and enhancing data transmission accuracy and reliability. Signal attenuation is a key factor affecting transmission quality during high-speed transmission. OM4 fiber minimizes modal dispersion by optimizing fiber structure and refractive index profile, thereby reducing signal attenuation and ensuring data integrity and accuracy during transmission.
Backward Compatibility
OM4 fiber not only offers exceptional performance but is also backward compatible with OM3 fiber. This means existing multimode fiber network equipment can be used with OM4 fiber without the need for extensive equipment upgrades or replacements.
Energy Efficiency, Lowering Operational Costs
Compared to other types of multimode fiber, OM4 fiber consumes less energy. This characteristic significantly reduces power consumption, thereby lowering operational costs.
Application Scenarios
The MultiCom® High-bandwidth OM4 optical fiber offers a seamless solution for high-density bandwidth applications, making it ideal for local area networks (LANs), central office environments, data centers, and high-performance storage area networks (SANs). It delivers the highest bandwidth while ensuring the lowest overall system cost.
Suitable for 10Gb/s network transmission over distances of up to 400 meters, this optical fiber is easy to install and fully compatible with existing fiber infrastructure.
