“Why Copper Wiring is Still Superior to Fiber Optics in Most Homes”


For many decades, copper cabling has been the standard for wiring homes and buildings for telephone, cable TV, and local area network (LAN) connections. However, in recent years, fiber optic cabling has emerged as an alternative with some key advantages. This article examines the pros and cons of each type of cabling to understand where each technology shines in home networking applications.

Copper Wiring Benefits

Copper wiring has been used for home networking for a very long time. This gives it some advantages:

For cost-sensitive applications where EMI is not a major concern, copper remains very viable.

Fiber Optic Advantages

However, fiber optic cabling offers key benefits:

For these reasons, fiber optics are considered technically superior for future-proof data networks in homes and businesses alike. The higher material and installation costs are offset by the far greater performance and long-term reliability.


In summary, copper wiring retains advantages for cost and ubiquity in many existing buildings. However, fiber optics are clearly superior in terms of bandwidth, distance, efficiency, durability, and immunity to interference. For these reasons, fiber is increasingly becoming the preferred choice for new construction and upgrading home networks to meet future data demands. Each technology has merits depending on the context, but fiber represents the future.
