UNIT 303: Level 3 Fibre Optic Cabling

DURATION: 3 days including assessments

Following the completion of mandatory units 301/302, candidates must complete one other Level 3 module to receive the full Level 3 Certificate. Unit 303 qualifies as one of three optional modules which must be completed in combination with unit 301/302 which are offered as a package.

The Unit 303 Fibre Optic Cabling course will provide attendees with an understanding of different types of fibre optic cabling commonly available in the data cabling and communications industry. This will include their uses and some of the associated standards and transmission characteristics, and expand knowledge of fibre testing methods. Candidates are assessed on this module by timed assignments.
