Uzbekistan Imported Hollow-Core Optical Fiber OM4

OM4 multimode optical fiber, widely imported into Uzbekistan from China, Russia, and Belarus, supports high-speed data transmission up to 10–100 Gb/s over medium distances.

Technical Overview of OM4 Fiber

OM4 is a laser-optimized multimode fiber with a 50/125 µm core/cladding diameter, designed for high-speed data networks. It supports:

• 10 Gb/s Ethernet up to 550 meters and 40/100 Gb/s up to 150 meters using MPO connectors .
• Effective Modal Bandwidth (EMB) of 5000 MHz·km, exceeding IEEE requirements for 10 Gb/s over 300 meters .
• Backward compatibility with OM3 fiber, allowing integration into existing multimode networks .
• Applications include data centers, campus backbones, and high-performance computing networks, supporting Ethernet, Fibre Channel, and InfiniBand . OM4 fibers are typically aqua-jacketed and optimized for VCSEL (Vertical Cavity Surface Emitting Laser) transceivers, providing low differential mode delay and high reliability . Hollow-core variants, while less common, offer reduced latency and improved signal integrity for specialized applications.

Import and Market Data in Uzbekistan

In 2024, Uzbekistan imported $14 million worth of optical fibers and cables, ranking as the 71st largest importer globally . The main sources of imported optical fiber were:

• China: $8.71M
• Russia: $2.72M
• Belarus: $939k
• Kazakhstan: $727k
• Turkey: $158k The fastest-growing import origins included Belarus, South Korea, and the United States . This indicates a strong reliance on international suppliers for high-performance fiber optic infrastructure.

Suppliers and Availability

Uzbekistan can source OM4 fiber from global manufacturers such as Corning, Prysmian, HES Kablo, and Turkuaz Kablo, with options ranging from 4-core to 96-core cables . These suppliers provide customized fiber solutions suitable for data centers, enterprise networks, and campus backbones.

Summary

For projects in Uzbekistan requiring high-speed, reliable optical connectivity, imported OM4 hollow-core fiber offers:

• High bandwidth and extended reach for 10–100 Gb/s networks
• Compatibility with existing multimode infrastructure
• Availability from multiple international suppliers, primarily from China, Russia, and Belarus
• Customizable core counts and cable configurations for specific network needs This makes OM4 fiber a practical choice for modern data centers, enterprise networks, and high-performance computing applications in Uzbekistan.
