CFOS/S – Fiber Optics Splicing Specialist Certification

This course is sanctioned by the Fiber Optic Association (FOA), the largest professional society of fiber optics in the world. FOA courses offered by BDI DataLynk are recognized by The US Department of Labor.

Exam Fee Included in Tuition!

Course Description:

This Splicing Specialist Training includes a complete PowerPoint presentation explaining the importance of high performance splicing and further details the points necessary to achieve these splices. The depth of this presentation is much greater than most textbooks and provides background information about splicing that is very important to the student. An overview of OTDR functions and trace understanding is also provided during this presentation. 85% hands-on classroom activities will provide training in both fusion and mechanical splicing of either single or multimode fiber optic cables. Inside or outside plant fiber optic cable types will be utilized at instructor’s discretion during these hands-on sessions along with fiber optics enclosures and splice trays. The student will be responsible for successfully making and testing both mechanical and fusion splices. In addition to the basic splicing activities outlined above, the student will further be required to correctly and efficiently install spliced fibers into splice trays and enclosures. The student will further be required to achieve a splice loss of less than 0.15 dB for all splices and demonstrate proficiency in interpretation of splice loss using OTDR splice traces.

CFOT certification from the Fiber Optics Association (FOA).

As of January 1, 2015, the student MUST have successfully passed the basic CFOT course within the preceding 12 months or have renewed their FOA membership within that time frame prior to attending the CFOS/T, CFOS/S, and/or the CFOS/O FOA Specialist courses offered by BDI Datalynk. There are no exceptions. Students are encouraged to register for all courses being offered at the individual locations with the understanding that the CFOT is the prerequisite for all other courses and it must be successfully completed first prior to attending any of the other “specialist” courses.

Course Objective:

Program prepares the student to take the CFOS/S (Certified Fiber Optics Specialist/Splicing) exam that is sanctioned by the FOA (Fiber Optics Association). The exam is given and graded the final day of class.

Text Book:

Fiber Optic Technician’s Reference Guide to Fiber Optics written by Jim Hayes, President of the Fiber Optic Association (FOA).


CFOS/S test is given and graded at the end of the class. A hands-on practical exam is given to insure student is proficient in installing and making mechanical and fusion splices according to industry standards.


As assigned by BDI DataLynk

Contact (Instructional) Hours:

16 – Hours (appx. depending on number of students)

Tools/Instructional Materials Needed:

A Projection Screen for Power Point presentations, a chalk or “white” board, Tables and chairs (no small desks please).

Particular Physical Demand(s) on student:

Students must be able to see, manipulate, and hold small tools and test equipment. Students must be able to read and speak the English language. Students must have the ability to announce to anyone in the classroom that lasers are about to be turned on or are currently on and active. Further, student must be able to hear and react to the announcement from anyone in the classroom that lasers are about to be turned on or currently active. Finally, students considering this or any other fiber optics course must understand that, because of safety issues in dealing high-power lasers and microscopes, the ability to communicate these important announcements to co-workers and the ability to hear and react to these announcements from co-workers is required once in the field working in this industry.
