Bit rate and losses limitations in single mode fiber

الملخص EN

In a WDM system a laser with only one line in its spectrum is needed, so the linewidth of laser must be specified.

The required linewidth will depend on the number of channels and bit rate in the proposed system.

In general the narrower the linewidth the better but this will usually be a cost/benefit tradeoff.

In this paper the limitations of bit rate and losses in single mode fiber are studied, and propose the perfect limitation that is used in the optical design.

All simulation was implemented using programs written in MALTAB 7 .
