 Crossover Cabling - Maximum Distance.
What is the maximum distance that could separate two systems connected by crossover cabling, using UTP CAT5 or above cable? Can this distance go upto 100 mts.? If possible please enlighten me with the cables and pin-out configurations to achieve this requirement

This exact situation was never addressed by the cabling standards, but assuming that you use stranded cable for the crossover cord, your length will be limited to 80 meters. This is because stranded cables are allowed to have 20% more attenuation that solid conductor ones as per TIA/EIA-568B
You can find pinouts for different kinds of applications here:
