Certified Fiber Optics Outside Plant Cabling Specialist (CFOS/O)


This course is recognized by the US Department of Labor and is sanctioned by the Fiber Optic Association (FOA). 

This in-person advanced specialist fiber optic training 2-day (16-hour) is for students who will be directly involved with installing Outside Plant (OSP) Fiber Optics Cabling. Further, it is an add-on course to their FOA portfolio once they have successfully completed the 3-day, basic CFOT course and can be taken concurrently with the CFOT course. This advanced Fiber Optic Training combines lecture sessions and 85% hands-on activities to prepare the student to take the CFOS/O, OSP hands on and written exams that are sanctioned by the FOA (Fiber Optics Association) and given and graded the final class day. This course introduces the student to industry standards governing the installation, testing, and troubleshooting of OSP fiber optics cable - used in the Outside Plant Rugged Environment. Students will learn how to properly identify OSP fiber cabling types, recognize various outside plant closures used in OSP fiber installation, install, prepare, terminate, splice, and properly test and troubleshoot installed OSP fiber cable to existing standards. Hands-on activities include both mechanical and fusion splicing.

Prerequisite: Students MUST have successfully passed the basic fiber optic training course, (CFOT) within the preceding 12 months or have renewed their FOA membership within that time frame prior to attending the (CFOS/T), (CFOS/S), (CFOS/O) and/or the (CFOS/H) FOA Specialist courses offered in partnership with BDI Datalynk at UCF. There are no exceptions. Students are encouraged to register for all courses being offered at the campus with the understanding that the CFOT course must be successfully completed prior to attending any of the other subsequent courses.

Course Objective: Program prepares the student to take the (CFOS/O) exam given and graded at the end of class.
