Optical Fibre
IEC/ITU-T certified single-mode & multimode fibre — 70,000 km produced per year in Morocco
As Morocco's leading optical fibre cable manufacturer, FBR Cables produces IEC 60793 and ITU-T G.657 compliant fibres. With a 70,000 km/year capacity and state-of-the-art German equipment, we meet the requirements of FTTH, backbone, metropolitan and the most demanding carrier telecom networks.
Understanding fibre optics for real-world deployment
An optical fibre consists of a core surrounded by cladding. In single-mode fibre, the core diameter is approximately 9 micrometres.
Signal propagation relies on different refractive indices between core and cladding, which keeps light confined within the fibre.
This mechanism is known as Total Internal Reflection (TIR), the foundation of high-speed long-distance transmission.

Key Specifications
Single-Mode Core
A single-mode fibre core is typically around 9 micrometres, enabling stable long-distance transmission.
MFD directly impacts coupling efficiency and link performance.
Propagation Speed
The speed of light in a vacuum is 300,000 km/s.
Actual speed in fibre depends on the material refractive index.
Guiding Condition
Optical guiding occurs when n1 > n2 (core refractive index higher than cladding).
This condition ensures optical signal confinement.
