You have been given the task of installing cables for an Ethernet network in your office. The building is an older one, and-you have limited work space. In addition, the network cable will have to share the existing conduit with telephone cable, and cable segments will be up to 135 meters in length. Which cable is best suited to this installation?

The correct option is fibre optic because Distance (The 135m Limit): Standard Copper Ethernet cables (like Cat 5e or Cat 6) have a maximum segment length of 100 meters. Since your run is 135 meters, copper would suffer from signal degradation and data loss. Fibre optic cables can easily run for several kilometres without a repeater.
Interference (EMI): The scenario mentions sharing a conduit with telephone cables. Copper cables (UTP) are susceptible to Electromagnetic Interference (EMI) from other lines. Because fibre uses light instead of electricity, it is completely immune to EMI.
Space Constraints: Older buildings often have crowded conduits. Fibre optic cable is generally much thinner and lighter than copper alternatives, making it easier to pull through tight, "limited" workspaces.
