Optical Fiber

Fiber optic cable

• glass fiber carrying light pulses, each pulse a bit

• high-speed point-to-point

• low error rate
• Bit flip rate is very low
• repeaters spaced far apart
• immune to electromagnetic noise

New Fiber Optics Tech Smashes Data Rate Record

Expanded bandwidth yields a transmission rate of 402 terabits per second

Internet speeds just got 4.5 million times faster - Interesting Engineering

This rate is the fastest ever recorded, achieved by utilizing specific new wavelength bands that have not been previously used in fiber optic systems.
