Questions

Which syllabus does the Optical Fibre Communication course follow?

It follows the BTEUP (Board of Technical Education, Uttar Pradesh) diploma syllabus for Optical Fibre Communication (Electronics Engineering, Semester 5). If your own board's or institute's syllabus differs, the centre follows your own syllabus.

Will this help in the semester examination?

Yes. Teaching is unit-wise as per the BTEUP scheme, with previous-year question practice, MCQ tests and doubt sessions before the semester exam.

Is FTTH and field testing covered?

Yes. Splicing, connectors, OTDR traces and power budget for FTTH links are explained.
