Question

Increasing data capacity (i.e., throughput) on an 802.3 LAN using UTP can be done by:a. Increasing wire gauge (e.g., go from Cat5e to Cat6 or 7)b. Adopting a line coding technique with a higher "M"c. Enabling both transmit and receive on a single wire pair using magnetic hybrid technologyd. All of the above

Answer 1

The correct option is:

d. All of the above

Increasing data capacity on an 802.3 LAN with UTP cable can be done by:

a. Increasing wire gauge - Cat6 or Cat7 cable has lower signal loss allowing for higher bandwidth than Cat5e.

b. Adopting a line coding technique with a higher "M" - Techniques like 8P8C coding provide more signal options than current RS-232, allowing for higher baud rates.

c. Enabling both transmit and receive on a single wire pair using magnetic hybrid technology - Magnetic hybrid circuits can allow full duplex communication on a single wire pair, doubling throughput.

d. All of the above - Implementing multiple techniques together will provide even greater improvements to bandwidth and throughput.

So the best approach is to implement a combination of increasing wire gauge, advanced line coding, and full duplex on a single pair. All of these techniques together will maximize the data capacity on an 802.3 LAN.
