4. 25) Optical Fiber, Cables, and Connectors 30 If a lens is used in between the emitter and fiber, some modifications to the previous formulas have to be done. What the lens can do for us is to match the output angle of the emitter to the acceptance angle of the receiving fiber. If properly done, the power coupled into the fiber is multiplied with the lens magnification factor M: M = drec/dem. All the preceding formulas need to be corrected for reflection losses. 2. 1. Optical Fiber Materials The material is primarily chosen to provide minimum attenuation.
