Bharat Broadband Network Limited (BBNL) has invited global tender for the Development (Creation, Upgradation, Operation & Maintenance and Utilisation) of BharatNet through Public Private Partnership model.
About the BharatNet Public Private Partnership
- The existing BharatNet was connecting all the Gram Panchayats (GPs) of the country by laying of OFC between Block and GPs.
What is OFC (Optical Fibre Cable)?
- A fiber-optic cable is composed of very thin strands of glass or plastic which is known as optical fibers.
- One cable can have as few as two strands or as many as several hundreds of them.
- These optical fiber cables carry information between two places using optical or light-based technology.
- A photoelectric cell will be required to turn the pulses of light back into electrical information the computer could understand.
