How you'll learn
100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within the intake, so the programme can be combined with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Zemax OpticStudio, MATLAB, Python with NumPy, Ansys STK and VPIphotonics, in free, academic or evaluation versions. Testing is studied through real procedures: inter-satellite optical link budget, turbulence simulation on a downlink and site selection for optical ground stations. Assessment is continuous by module, plus the final integrating project.
Standards covered: CCSDS 141.0-B (Optical Communications Physical Layer), CCSDS 142.0-B, IEC 60825-1, Recommendation ITU-R P.1622, SDA Optical Communications Terminal (OCT) Standard, ECSS-E-ST-50C, Recommendation ITU-R P.1814.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.

Frequently asked questions
The programme totals 300 hours over 3 months. You set your own pace within each intake, and your tutor helps you plan the workload around your job.
You work with Zemax OpticStudio, MATLAB, Python with NumPy, Ansys STK, VPIphotonics, using free, academic or evaluation versions. Your tutor indicates the free alternative wherever one exists.
A SEIUM Institute certificate, awarded on passing the continuous assessment and the final project. It is SEIUM's own qualification, not an official state degree; its recognition depends on the programme completed and the regulations of each country.
Yes. Modules passed are recognised in a higher programme in the same area (postgraduate diploma or master's). Ask about the recognition policy when you enrol.
No prior qualification is required; you need an internet connection, a computer able to run the programme software and English sufficient to read technical standards.
Start dates are set by SEIUM's faculty for each intake. Our admissions team will confirm the next available date when you apply.
