Analyzing the Best Communication Media for Physical Layer: A Critical Study

The communication speed between sender and receiver is major issue. Physical layer in OSI Model is responsible to communicate binary information from sender to receiver. The best communication media can provide us the better speed of communication. In this research paper, a critical study has done on traditional and latest communication media on physical layer. Shielded Twisted Pair (STP) is the oldest technique then Co-axial Cable introduced in the market which provides higher speed and lesser disturbance than STP. Optical Fiber changed the era of internet and provides higher speed and lesser disturbance then all traditional media. Now in today’s world a huge amount of data has to be transferred, which required higher speed. To trans fer multi-media content like real time high quality videos, a higher speed is required. This higher speed can be provided by Gigabyte Passive Optical Network (GPON).
