Tools Used: ModeSYS
ModeSYS helps model Gigabit Ethernet Physical Medium Dependent (PMD) sublayer according to IEEE 802.3 Standard. All eight scenarios described in the IEEE 802.3, "Clause 38, Physical Medium Dependent (PMD) sublayer and baseband medium, type 1000BASE -LX (Long Wavelength Laser) and 1000BASE-SX (Short Wavelength Laser)" can be modeled in ModeSYS.
The topology snapshot of 1000Base-SX case with 62.5-micron MMF of 220-m is shown below:
