Transceivers are lasers that are wavelength specific and convert electrical data signals from data switches into optical signals. Once this process has been performed the data signals can then be transmitted over optical fiber.
Dark fiber refers to unused or underused fiber optic infrastructure, including optical fibers, fiber cables and repeaters. We have seen people talking about the benefits of deploying dark fiber, but rarely see them discussing how to light up dark fiber. Today we are going to talk about how to light up dark fiber.

Both OSPF and EIGRP are Dynamic Routing Protocols. Dynamic routing protocols allow routers to select the best path according to real-time logical network layout changes. The main feature of dynamic routing protocol is its ability to re-route traffic when more optimal paths become available or when links along the most optimal path fail.
