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 . TX/RX is reversed
B. An incorrect cable was used
C. The device failed during installation
D. Attenuation is occurring
Answer: A
Explanation:
The most likely cause of the issue where the fiber connection from a device to a switch is not working is that the TX/RX (transmit/receive) is reversed. When connecting fiber optic cables, it is important to ensure that the TX of one device is connected to the RX of the other device and vice versa. If the TX/RX is reversed, data cannot be transmitted successfully.
