I-PLC isihlukanisi noma i-planar lightwave circuit splitter iyisakhi esingenzi lutho esine-waveguide ekhethekile eyenziwe nge-planar silica, i-quartz noma ezinye izinto.Isetshenziswa ukuhlukanisa umucu wesiginali ye-optical ibe imicu emibili noma ngaphezulu.Impela, siphinde sinikeze isihlukanisi sebhokisi le-ABS le-PLC.I-fiber optic splitter ingenye yezinsiza ezibaluleke kakhulu zokungenzi lutho kusixhumanisi se-fiber optical.Ama-Waveguides akhiwe kusetshenziswa i-lithography ku-silica glass substrate, evumela ukuhambisa amaphesenti athile okukhanya.Njengomphumela, izihlukanisi ze-PLC zinikeza okunembile ngisho nokuhlukaniswa nokulahlekelwa okuncane kuphakheji ephumelelayo.Kuyidivayisi ye-optical fibre tandem enamatheminali amaningi okokufaka nokukhiphayo, ikakhulukazi asebenza kunethiwekhi ye-passive optical (EPON, GPON, BPON, FTTX, FTTH njll.) ukuze kuxhunywe i-MDF kanye nesisetshenziswa setheminali kanye nokuhlanganisa isignali yokubona.
