Objective :
- Measurement of Numerical aperture (NA) of the Optical Fiber.
- The aim of the experiment is to study various types of losses that occur in optical fibers and measure the loss in dB of two fiber patchcords.
Apparatus and Accessories :
- One meter PMMA Fiber patch cord ( cable 1).
- Five– meter PMMA patchcord ( cable 2 ).
- In – line SMA adaptor.
- LED source.
- Optical power meter.
- Mechanical jig.
- Small screen.
