Ukuqonda unxibelelwano lwefiber optical lusekelwe kumgaqo wokubonakaliswa kokukhanya ngokupheleleyo.
Xa ukukhanya kusasazeka phakathi kwe-fiber optical, isalathisi se-refractive n1 ye-fiber core iphezulu kune-cladding n2, kwaye ilahleko ye-core iphantsi kune-cladding, ukwenzela ukuba ukukhanya kuya kubonakaliswa ngokupheleleyo. , kwaye amandla ayo okukhanya ahanjiswa ikakhulu kwi-core. Ngenxa yokukhanya okupheleleyo okulandelelanayo, ukukhanya kunokudluliselwa ukusuka kwelinye icala ukuya kwelinye.
Ihlelwe ngemo yothumelo: imowudi enye kunye neendlela ezininzi.
Imowudi enye inomlinganiselo omncinci ongundoqo kwaye inokudlulisa kuphela amaza okukhanya emowudi enye.
I-Multi-mode optical fiber inobubanzi obungundoqo kwaye inokuhambisa amaza okukhanya ngeendlela ezininzi.
Singakwazi ukwahlula i-fiber optical yemodi enye kwi-multi-mode optical fiber ngombala wenkangeleko.
Uninzi lwemicu ye-optical mode enye inejacket emthubi kunye ne-blue connector, kwaye i-cable core yi-9.0 μm. Kukho amaza amabini asembindini wefayibha yendlela enye: 1310 nm kunye ne-1550 nm. I-1310 nm isetyenziselwa ukuhanjiswa kwexesha elifutshane, umgama ophakathi okanye umgama omde, kwaye i-1550 nm isetyenziselwa ukuhanjiswa komgama omde kunye ne-ultra-long-long. Umgama wothumelo uxhomekeke kumandla okuhanjiswa kwemodyuli ye-optical. Umgama wothumelo lwe-1310 nm izibuko lemowudi enye yi-10 km, 30 km, 40 km, njl. njl., kwaye umgama wothumelo we-1550 nm izibuko lemowudi enye yi-40 km, 70 km, 100 km, njl.
Iifiber ze-optical mode ezininzi zi-orenji / ibhatyi engwevu kunye nezixhumi ezimnyama / ze-beige, i-50.0 μm kunye ne-62.5 μm cores. Ubude obusembindini befayibha yeendlela ezininzi ngokuqhelekileyo bungama-850 nm. Umgama wothumelo lwe-multi-mode fiber mfutshane, ngokubanzi ngaphakathi kwe-500 m.
