Move 10 GbE traffic from copper to long-haul fiber without redesigning the access layer. The Axiom MC10-S3L20-AX converts 10GBASE-T to 10GBASE-LR, giving infrastructure teams a practical path from RJ45-based equipment to single-mode fiber uplinks. With LC connectivity, 1310 nm optics, and support for distances up to 20 km, it fits backbone extensions, building interconnects, and aggregation links where copper reach ends. This converter is a strong fit when you need to preserve existing 10GBASE-T switching while extending transport across a fiber plant. It helps reduce the cost and disruption of replacing edge hardware just to reach a remote closet, IDF, or campus building. The LR side is designed for long-distance optical transport, while the copper side keeps compatibility with installed 10GBASE-T equipment. For teams standardizing on 10 GbE, this model offers a clean transition point between media types. It is purpose-built for environments where link distance, signal integrity, and predictable interoperability matter more than adding unnecessary complexity.
