OT is the use of computers to monitor or alter the physical state of a system, such as the control system for a power station or the control network for a rail system. The term has become established to demonstrate the technological and functional differences between traditional IT systems and Industrial Control Systems environment, the so-called "IT in the non-carpeted areas"
Examples of operational technology include:
Computer Numerical Control (CNC) systems
Scientific Equipment (e.g. digital oscilloscopes)
The small form-factor pluggable (SFP) is a compact, hot-pluggable optical module transceiver used for both telecommunication and data communications.
Fast Ethernet (FE) & Gigabit Ethernet (GE) Information
Fast Ethernet (FE) Ports is commonly able to achieve speeds of 100Mbit/s
Gigabit Ethernet (GE) Ports are capable of speeds of 1000Mbit/s which is also 1Gb/s
