This paper has clarified the positive and negative effects of 3.1% germania and 1% fluorine DS fibers in multi-mode silica profile. The group delay and the total fiber dispersion against operating wavelength for PS and various doped silica (DS) fibers are demonstrated and assured by using OptiFiber simulation. The material, waveguide and total fiber dispersions are demonstrated against wavelength for the PS fiber, 3.1% germania DS (GDS) fiber and 1% fluorine DS (FDS) fiber. Besides the mode field diameter, fiber material loss, fiber bending loss and the dispersion group delay are simulated and clarified against the operating wavelength for PS and different DS fibers. The study gives the effects of the dopant ratio of germania and fluorine on the zero dispersion wavelength shift and DS.

The work outlined ideal single mode laser operation with single measured drive phase shift/conventional Mach–Zehnder modulators (MZM) in optical access networks is simulated and analyzed. Maximum signal power level versus spectral wavelength and time domain spectrum after fiber channel based 1.5 splitting ratio conventional/phase shift MZM and Idea single mode laser is measured accurately. Maximum Q coefficient of 35.87 and mini bit error rates of 2.3279 × 10−282 in the case of conventional MZM and idea single mode laser. Maximum Q coefficient of 17.86 and mini error rate of 1.0376 × 10−71 in the case of phase shift MZM and Idea single mode laser.

This paper clarified the optical fiber communication system links the performance signature for short-indoor applications. The electrical propagation delay time is investigated for copper links. The polystyrene optical link propagation delay time is also analyzed. The optical pulse broadening and the data transmission bit rates in the optical links are analyzed. The electrical/optical links performance is discussed with the variations of electrical/optical link variations and ambient temperature variations. The optical link performance efficiency has presented better performance than the electrical links, especially for short-indoor applications.
