Uma sikhetha imojula yokubona, ngaphezu kokupakishwa okuyisisekelo, ibanga lokudlulisela, nezinga lokudlulisela, kufanele futhi sinake lezi zinto ezilandelayo:
1. Uhlobo lwefayibha
Izinhlobo zefiber zingahlukaniswa zibe imodi eyodwa kanye nemodi eminingi. Amaza aphakathi nendawo wamamojula okusebenza emodi eyodwa ngokuvamile angu-1310nm no-1550nm, futhi asetshenziswa kanye nemicu yokubona yemodi eyodwa. I-fiber optical yemodi eyodwa inemvamisa yokudlulisa okubanzi namandla amakhulu okudlulisela, futhi ilungele ukudluliswa kwebanga elide. Ubude obumaphakathi be-multimode optical module ngokuvamile bungu-850nm, futhi busetshenziswa kanye ne-multimode optical fiber. I-Multimode fiber ineziphambeko ze-modal dispersion, futhi ukusebenza kwayo kokudlulisela kubi kakhulu kunokwe-fiber yemodi eyodwa, kodwa izindleko zayo ziphansi, futhi ifanele umthamo omncane kanye nokudluliselwa kwebanga elifushane.
2. I-Optical fiber interface
Izixhumanisi zamamojula ajwayelekile zifaka i-LC, SC, MPO, njll.
3. Izinga lokushisa lokusebenza
Izinga lokushisa elisebenzayo lemojula ye-optical yibanga lezohwebo (0°C-70°C), ibanga elinwetshiwe (-20°C-85°C), kanye nebanga lezimboni (-40°C-85°C). Amamojula okubona anephakheji efanayo, isilinganiso, nebanga lokudlulisela ngokuvamile anezinguqulo ezimbili: ibanga lezohwebo kanye nebanga lezimboni. Imikhiqizo yezinga lezimboni isebenzisa amadivaysi anokubekezelela izinga lokushisa okungcono, ngakho intengo yemikhiqizo yezinga lezimboni iphezulu. Sidinga ukukhetha izinga lokushisa lokusebenza lemojula ye-optical ngokuya ngendawo yokusetshenziswa yangempela.
4. Ukuhambisana Kwedivayisi
Ngoba abakhiqizi bemishini abakhulu, ukuze banikeze imikhiqizo nezinsizakalo ezingaguquki, bonke bavame ukuba nendawo ezungezile evaliwe. Ngakho-ke, amamojula optical awakwazi ukuxutshwa nanoma yiluphi uhlobo lwemishini. Uma sithenga imojula yokubona, sidinga ukuchazela umthengisi ukuthi yimaphi amadivayisi imojula ye-optical okudingeka isetshenziswe kuwo, ukuze sigweme inkinga yamadivayisi angahambisani kumojula yokubona.
5. Inani
Ngokuvamile, amamojula okubona anophawu olufanayo nohlobo lwemishini ayabiza. Ukusebenza kanye nekhwalithi yamamojula we-optical ahambisanayo evela eceleni kungashiwo ukuthi kuyafana namamojula optical brand okwamanje, kodwa intengo inezinzuzo ezisobala.
6. Isevisi yekhwalithi kanye ne-after-sales
Ngokuvamile, ngeke kube nezinkinga ngamamojula optical ngonyaka wokuqala wokusetshenziswa, futhi iningi lawo lizovela kamuva. Ngakho-ke zama ukukhetha umphakeli onekhwalithi ezinzile.
