Premium OM1 (62.5/125µm) Multimode Fiber for Advanced LAN Communication
The OM1 (62.5/125µm) Multimode Fibre is engineered to meet the robust demands of legacy and modern Local Area Networks (LAN). As a premier component in fiber optic communication systems, this multimode fiber complies with and exceeds the stringent requirements of the ISO/IEC 11801-1 OM1 specification, IEC 60793-2-10 A1-OM1 specification, and TIA-492AAAF A1-OM1 specification.
Manufactured utilizing the state-of-the-art PCVD (Plasma Chemical Vapor Deposition) process, it features an extremely refined refractive index profile and superior geometry uniformity. Furthermore, the fiber is coated with a proprietary dual-layer UV curable acrylate, ensuring exceptional resistance to micro-bending and optimized performance in tight-buffer cable applications.
