BTEC Level 3 Advanced Test and Measurement

This BTEC Test & Measurement course provides additional training for those who wish to increase their understanding or specialise in the field of Fibre Optic testing. This course covers testing techniques and the use test equipment (VFL, Light Source/Power Meter & OTDR). Chromatic & polarisation mode dispersion and FTTX testing are also covered in this BTEC qualification.
