Intro to Networking

Fiber optic cable comes in various shapes and sizes which can be used for different types of deployments. Depending on the cost of goods, the distance of the run, and throughput requirements

How to determine the number of cores required when using fiber optic?

Generally speaking, the number of optical cores in an optical fiber is the total number of device interfaces multiplied by 2, plus 10% to 20% of the spare number.

A single fiber connection into two independent routers

The easiest way to do is, terminate your ISP connection to single router with at least 2 independent LAN interfaces, then you can build 2 separate networks there.
