COST- EFFECTIVE APPROACH FOR 100GBPS VCSEL-MMF LAN’S

VCSELs enable many types of applications, such as optical computing and optical information processing. In this work, firstly different physical parameters Temperature, cavity volume and Bias current have been analysed on VCSEL laser. Further different modulation formats i.e. NRZ, CSRZ and MDRZ are analysed for the first time using VCSEL Laser over GI-MMF in terms of Qfactor and BER.MDRZ comes out to be best modulation formats to prolong the system reach to28Km. Performance analysis of 100 Gbps MIMO system using MDRZ modulation format over 28 km MMF has also been investigated at different distances varied from 8km to 28 km in terms of Q-factor and BER.
