Transmission demystified  |    A 2 day training course

Transmission demystified training course description

Transmission is the process of sending information along a medium of, copper, fibre or wireless. This course looks at transmission techniques for both telecommunications and data communications with a particular focus on Microwave, SDH, DWDM transmission. The course aims to demystify these technologies by explaining all the buzzwords used in transmission.
