In this paper we have proposed design modifications in fiber optic loop buffer switch. This paper discusses an automatic gain controlling (AGC) scheme for the loop buffer. We have shown that by changing the position of EDFA automatic gain controlling scheme will not be required. We have utilized the availability of filter in tunable wavelength converter (TWC) to reduce number of components in the...
Several techniques for optical buffering have been given in past and still a lot of research is being done. Also, the rapid growth of the broadband communication has placed extreme demands upon the telecommunication infrastructure. This has generated an urgent requirement to introduce new technologies. Wavelength division multiplexing (WDM) is one of those techniques, which allows simultaneous propagation...
