Question 1
The encoding technique used to transmit the signal in gigabit ethernet technology over fiber optic medium is:
Step-by-Step Solution
Detailed Explanation:
Gigabit Ethernet (1000BASE-X) over fiber optic cables uses 8B/10B encoding.
In 8B/10B encoding, 8-bit data blocks are mapped to 10-bit symbols to ensure sufficient state transitions for clock recovery and maintain DC balance.
4B/5B is used in Fast Ethernet (100BASE-FX), while Manchester/Differential Manchester is used in 10 Mbps Ethernet.
