OSP (outside plant) cable plants look similar, but the the fiber is all singlemode and cable runs may be long, requiring splices every 2-4 km. Theoretically it can be done, comes out to about 2 minutes per splice. But there's a physical limit for your body and also this whole thing only works under the assumption that the fibers are ready to go and you're splicing for 8 hours. Through splicing, fiber optic technicians can extend the length of the fiber to make it long enough for use in a required cable run. As fiber optic cables are generally only produced in lengths up to around 5km, so when lengthier connections are needed, splicing two cables together becomes. Precise optical fiber splicing reduces signal loss, improves network reliability, and extends infrastructure lifespan. Poor fiber splicing, on the other hand, can lead to performance issues and increased maintenance costs.
