Opening a window in the fiber optic cable
Through a wall, typically near where the exterior cable terminates. Through a window frame, using a specialized low-profile fiber optic window pass-through cable if drilling through a wall is not feasible or desired. The stupid internet guy has passed the wire though the grill of my window, suggesting keep it little open for the wire to be safe. The. Many installations involve splitting the fibers in a cable or dropping a small fiber count cable from a large backbone cable. Backbone cables of 144-288 fibers are common and larger ones are becoming more common too. The problem we have is that the cable runs very close to our house, both ruining the view, and being very close on our. Unlike traditional cable or DSL, fiber optics utilizes thin strands of glass or plastic to transmit data as pulses of light. This fundamental difference is what enables the incredible speeds and reliability associated with fiber.
