A technician is installing a new fiber connection to a network device in a datacenter.
The connection from the device to the switch also traverses a patch panel connection.
The chain of connections is in the following order: -> Device -> LC/LC patch cable -> Patch panel -> Cross-connect fiber cable -> Patch panel -> LC/LC patch cable -> Switch The connection is not working.
The technician has changed both patch cables with known working patch cables.
The device had been tested and was working properly before being installed.
Which of the following is the MOST likely cause of the issue?

A. B. C. D.A.
The most likely cause of the issue is D. Attenuation is occurring.
Attenuation is the loss of signal strength as it travels through a medium. In the case of fiber connections, attenuation can occur due to various reasons, including excessive length, dirty connectors, or damage to the fiber cable itself.
In this scenario, since the technician has already changed both patch cables with known working patch cables and the device had been tested and was working properly before being installed, it is less likely that the issue is caused by an incorrect cable or a device failure during installation.
The chain of connections includes two patch panels, which increases the likelihood of attenuation. Moreover, fiber connections are more susceptible to attenuation compared to copper connections. It is possible that the attenuation is occurring at the patch panel or cross-connect fiber cable.
Therefore, the technician should inspect and clean the connectors, check the fiber cable for any signs of damage, and test the signal strength to isolate the issue further.
