Fiber Optic
By Corning Inc.
Fiber optic cables use thin strands of glass or plastic to transmit data as light pulses, offering extremely high bandwidth, low signal loss, and immunity to electromagnetic interference.

Coaxial
By Belden Inc.
Coaxial cables consist of a central conductor surrounded by insulation and an outer shield, primarily used for TV, broadband internet, and radio transmissions, providing solid performance at a lower cost.

AI Verdict
Fiber optic emerges as the superior choice for applications demanding high speed, long‑distance, and future‑proof connectivity, while coaxial still holds value for low‑cost, legacy‑compatible, or short‑range scenarios.
Frequently Asked Questions
Can fiber optic cables replace coaxial in all cases?
No. Fiber is ideal for high‑performance networks, but coaxial remains a cost‑effective option for short‑range or legacy systems.
What is the typical price difference per metre?
Fiber can cost roughly $1–$3 per metre, whereas coaxial is usually $0.20–$0.50 per metre.
How does signal attenuation compare?
Fiber incurs about 0.2 dB/km, while coaxial can experience 80–85 dB/km, making fiber suited for 100 km runs versus coaxial’s 2–3 km.
Is maintenance easier for fiber?
Fiber requires specialized tools and trained personnel; coaxial can be serviced with standard cable tools, making maintenance less intensive for short runs.
