Which of the following steps should the architect take to troubleshoot the issue?

After installing a series of Cat 8 keystones, a data center architect notices higher than normal interference during tests.

Which of the following steps should the architect take to troubleshoot the issue?
A . Check to see if the end connections were wrapped in copper tape before terminating.
B . Use passthrough modular crimping plugs instead of traditional crimping plugs.
C . Connect the RX/TX wires to different pins.
D . Run a speed test on a device that can only achieve 100Mbps speeds.

Answer: A

Explanation:

Importance of Proper Termination:

Cat 8 cabling requires precise termination practices to ensure signal integrity and reduce interference. One common requirement is to wrap the end connections in copper tape to maintain shielding and reduce electromagnetic interference (EMI).

Interference Troubleshooting:

Interference in high-frequency cables like Cat 8 can be caused by improper shielding or grounding.

Checking the end connections for proper wrapping in copper tape is a crucial step.

Why Other Options are Less Likely:

Passthrough modular crimping plugs: Not specifically related to interference issues and are typically used for ease of cable assembly.

Connecting RX/TX wires to different pins: Would likely result in no connection or incorrect data transmission rather than interference.

Running a speed test on a device that can only achieve 100Mbps speeds: This would not diagnose interference and would not provide relevant information for Cat 8 cabling rated for higher speeds. Corrective Actions:

Verify that all end connections are properly wrapped with copper tape before termination.

Ensure that the shielding is continuous and properly grounded throughout the installation.

Retest the cabling for interference after making corrections.
