Optical Fiber is a revolutionary technology enabling the world to be connected.
It is a flexible and transparent medium made from silica, glass, or plastic. Optical Fiber carries information in the form of light by reflection through the principle of total internal reflection.
Compared to copper:
Higher bandwidth
Longer distances
No electromagnetic interference (EMI)
More secure
Lightweight
Optical fiber is used today in almost every industry, including telecommunications, medicine, aerospace, and automotive.
Lightweight & thin (smaller than a hair)
High bandwidth
Unaffected by electromagnetic interference
Encrypted data transfer
Long-distance communication
Low attenuation & low latency
Non-combustible
Requires trained installation personnel
Difficult and tricky to join or splice
Costs more when installing
Unlike metal wires, they become brittle
Requires costlier equipment for testing
