CCrossover
DF-Connector

Explanation

Multimode fiber is designed for shorter distances, typically up to 300–550 meters depending on the standard (e.g., OM3/OM4), making it ideal for connecting buildings within a campus or short-range runs. It is also less expensive than singlemode fiber. Singlemode fiber is designed for long-distance transmission (several kilometers) and uses a smaller core with laser light - it would work but is unnecessarily expensive for this short run. Crossover refers to copper Ethernet cable wiring, and F-Connector is a coaxial cable connector, neither of which are fiber types.
