Layer 1: Physical Layer. Layer 1 is fairly easy ... Those are essentially Layer 2 switches with a router built into the backplane for speed.

Layer 2 and Layer 3 switches differ primarily in their routing capabilities. A Layer 2 switch operates solely based on MAC addresses, ...

In addition to this, Layer 1 switches also have the ability to convert one media type to another (e.g. Ethernet to Fiber) using cross-connects.

A Layer 1 switch does not read, manipulate or use packet/frame headers to route the data. Layer 1 switches are fully transparent to the data and typically have ...
