Does this mean that optical port modules outperform electrical port modules? The answer is no. In fact, electrical port modules deliver performance comparable to that of optical port modules while boasting unique advantages. Install dust plugs on idle optical ports. Wear an ESD wrist strap or ESD gloves. It plugs into network equipment (like switches, routers, or servers) and its primary function is to convert electrical signals from the device into light signals for transmission over fiber. An SFP port (Small Form-factor Pluggable) is a compact, hot-swappable interface used in network switches, routers, and firewalls to support fiber optic or copper networking cables.
