Optical fiber can make networks future-proof
The age old copperb a s e d n etwo r k s struggle to meet the demands of the rapidly evolving world of digitization due to limited bandwidth capacities and susceptibility to cyber-attacks. This has led to deterioration in the data & service quality, and high operational costs for telecom operators. Additionally, communication networks based on copper cables are not capable of meeting the rapidly exploding bandwidth requirements and are energy inefficient. This has led to deterioration in the data & service quality, and high operational costs for telecom operators.
With this in the backdrop, the Government is now laying the backbone of future communication network by relying on advanced fiber optic technology in projects like BharatNet, NFS etc. Even then, given the low fiberization in India, focused efforts need to be taken as over 80 percent of the present network rides on copper cables or microwave, which need to be upgraded for a secure highcapacity network.
The benefits of using optical fiber for critical national infrastructure development such as Smart Cities, BharatNet, and NFS are much beyond the ones that can be derived by copper cables. Take the case of Smart Cities where smart utilities like electricity grid, water, transport networks, surveillance and emergency services will be dependent on high-speed broadband connectivity.
Data transmission through optical fiber cables has become the safest form of data communication as it is extremely difficult to tap as fibers do not radiate signals. If an attempt is made to break the physical security of the fiber system, the solution provider immediately gets notified about the attempt.
Optical fiber networks can also provide for extremely reliable data transmission as it is completely immune to many environmental factors that affect copper cables. They are immune to electrometric interference and radio-frequency interference (EMI/ RFI), crosstalk, impedance problems, and more.
Today, with the evolution in technology, many innovations in optical fibers like intrusion-proof, macro bend insensitive, and capable of sustaining robust communications in spite of large amount of fiber cuts have also become a reality. The intrusion proof system, in case of breakdown, allows the data packet to shift from one network to another seamlessly.
