1.Isigaba se-Laser
I-laser iyisakhi esimaphakathi kakhulu semojula yokubona ejova okwamanje kumpahla ye-semiconductor futhi ikhiphe ukukhanya kwe-laser ngokusebenzisa ama-photon oscillations kanye nenzuzo emgodini. Njengamanje, amalaser asetshenziswa kakhulu ama-laser e-FP kanye ne-DFB. Umehluko wukuthi impahla ye-semiconductor kanye nesakhiwo somgodi kuhlukile. Intengo yelaser ye-DFB ibiza kakhulu kunelaser ye-FP. Amamojula okubona anamabanga okudlulisa afika ku-40KM ngokuvamile asebenzisa amalaser e-FP; amamojula abonakalayo anamabanga okudlulisela ≥40KM ngokuvamile asebenzisa amalaser e-DFB.
2.Ukulahlekelwa nokuhlakazeka
Ukulahlekelwa ukulahlekelwa amandla okukhanya ngenxa yokumuncwa nokuhlakazeka kwendawo ephakathi nendawo kanye nokuvuza kokukhanya lapho ukukhanya kudluliselwa kufiber. Le ngxenye yamandla ihlakazwa ngesilinganiso esithile njengoba ibanga lokudlulisela likhuphuka.Ukuhlakazeka kubangelwa isivinini esingalingani samaza kagesi amaza ahlukene asakazeka endaweni efanayo, okubangela izingxenye ezihlukene zamaza zesignali ye-optical ukufinyelela ukuthola ukuphela ngezikhathi ezihlukene ngenxa yokuqoqwa kwebanga lokudlulisela, okuholela ekwandiseni ukushaya kwenhliziyo futhi ngaleyo ndlela kungakwazi ukuhlukanisa inani lamasignali.Le mingcele emibili ithinta ikakhulukazi ibanga lokudlulisela lemojula ye-optical. Enqubweni yangempela yohlelo lokusebenza, imojula ye-optical engu-1310nm ngokuvamile ibala ukulahleka kwesixhumanisi kokuthi 0.35dBm/km, futhi imojula yokubona engu-1550nm ngokuvamile ibala ukulahleka kwesixhumanisi kokuthi .20dBm/km, futhi ibala inani lokuhlakazeka. Inkimbinkimbi kakhulu, ngokuvamile kuphela ireferensi.
3.Amandla optical adlulisiwe kanye nokwamukela ukuzwela
Amandla okukhanya adlulisiwe abhekisela emandleni okukhanya okukhipha omthombo wokukhanya ekugcineni kokudlulisa kwemojula ye-optical. Ukuzwela okutholayo kubhekisela emandleni okubonwa amancane atholiwe emojula ye-optical ngenani elithile kanye nezinga lephutha lebhithi. Amayunithi alawa mapharamitha amabili yi-dBm (okusho i-decibel milliwatt, i-logarithm yeyunithi yamandla mw, ifomula yokubala ngu-10lg, u-1mw uguqulelwa ku-0dBm), esetshenziselwa kakhulu ukuchaza ibanga lokudlulisela lomkhiqizo, ubude obuhlukile be-wavevel, izinga lokudlulisela kanye namandla okudlulisa amehlo emojula ye-optical kanye nokuzwela kuzohluka, inqobo nje uma ibanga lokudlulisela lingaqinisekiswa.
Impilo yemojula ye-4.Optical
Izindinganiso ezihlangene zamazwe ngamazwe, amahora angu-50,000 omsebenzi oqhubekayo, amahora angu-50,000 (alingana neminyaka engu-5).
Amamojula we-SFP optical wonke ayi-LC interfaces. Amamojula we-GBIC optical ayiwo wonke ama-SC interface. Ezinye izindawo zokuhlangana zihlanganisa i-FC ne-ST.
