so tGVD = |D|Lσλ where D is dispersion, L is length of fiber and σλ is half power bandwidth of source (σλ can be measure by hooking the source up to a spectrum analyser and measuring the bandwidth at half power). The values of D and L are defined in properties window of the optical fiber. As for Tmod there is no modal effect in single mode fibers so Tmod= 0
