Solution
To resolve the issue of noise interference at the physical layer causing loss of network signal in the Cambridge Law Department, the following measures should be taken:
-
Ensure that you do not leave more than an inch of exposed cable before a twisted-pair termination: This is a good practice as it reduces the amount of cable that can potentially pick up interference. However, this alone may not completely solve the problem if the source of the interference is strong or close to the cables.
-
Install the cables through cable conduits and seal the ends of these pipes: This is a very effective measure. Cable conduits act as a physical barrier that protects the cables from external interference. Sealing the ends of the pipes prevents interference from entering the conduit.
-
Use patch panels to organize and connect lines: While this is a good practice for cable management and can make troubleshooting easier, it may not directly help in reducing the noise interference.
-
Ensure that the cables are at least 3 feet away from fluorescent lights or other sources of EMI: This is a crucial step. Electromagnetic interference (EMI) from sources like fluorescent lights can cause significant signal degradation. Keeping the cables at a safe distance from these sources can greatly reduce the noise interference.
In conclusion, all these measures are beneficial, but the most effective ones for reducing noise interference would be installing the cables through cable conduits and keeping them away from sources of EMI.

A college is building a new dormitory on its campus. Workers are digging in the ground to install a new water pipe for the dormitory. A worker accidentally damages a fiber optic cable that connects two of the existing dormitories to the campus data center. Although the cable has been cut, students in the dormitories only experience a very short interruption of network services. What characteristic of the network is shown here?
