Loss Testing of Premises Fiber Optic Links
The testing of premises fiber optic cabling links requires precise methods for referencing to obtain accurate and valid test results. Loss testing for multimode fiber cabling is specified in ANSI/TIA/EIA-526-14A. This standard contains two test procedures: Method A and Method B. This application note describes Methods A and B, and explains why Method B is the proper method for testing fiber links contained in premises networks.
This note also proposes a new test procedure as an adaptation to Method B to overcome some disadvantages associated with Method B. This new test procedure is the preferred method because it provides results conforming to Method B while offering installers more flexibility for testing fiber links with all types of connectors, including Small Form Factor (SFF) connectors. This note also details other advantages of the Method B adaptation for simplifying the testing process and reducing the opportunity for errors.
