Which type of cable has high bandwidth, supports high data transfer rate, signals can travel longer distances, and electromagnetic noise cannot affect the cable, however expensive? Identify the transmission media.

Correct option is B

The transmission media that offers high bandwidth, supports high data transfer rates, allows signals to travel longer distances without degradation, and is resistant to electromagnetic interference is Optical Fiber. Optical fiber uses light to transmit data, making it immune to electromagnetic noise and capable of transmitting data over longer distances compared to other cables. While it is more expensive, it offers superior performance, especially for high-speed internet and communication networks.
Important Key Points:
1. High Bandwidth: Optical fiber supports extremely high bandwidth, enabling the transfer of vast amounts of data quickly.
2. Longer Distance: Signals in optical fiber can travel over long distances without significant loss of quality, making it ideal for long-range communication.
3. Resistance to Electromagnetic Interference: Since optical fiber transmits data via light, it is not affected by electromagnetic noise, unlike electrical cables.
4. High Data Transfer Rate: Optical fiber offers faster data transmission speeds compared to coaxial, twisted pair, or even Cat6 cables.
5. Cost: Although optical fiber is more expensive than other cables, its benefits in performance outweigh the cost for applications requiring high-speed data transfer.
Knowledge Booster:
· Option (a): Coaxial cables are commonly used for cable TV and broadband internet. While they do offer some shielding against electromagnetic interference, they cannot match optical fiber's data transfer rate, distance, and immunity to noise.
· Option (c): Twisted pair cables, commonly used in networking (such as Ethernet cables), are less expensive but have lower bandwidth and are more susceptible to electromagnetic interference. They also have shorter distance limits compared to optical fiber.
· Option (d): Cat6 cables are a type of twisted pair cable that supports higher data transfer rates than traditional twisted pair cables but still cannot match the performance of optical fiber in terms of distance, bandwidth, and immunity to electromagnetic interference.
