Xa sikhetha imodyuli ye-optical, ukongeza kwisiseko sokupakishwa, umgama wothumelo, kunye nesantya sothumelo, kufuneka sinikele ingqalelo kwezi zinto zilandelayo:
1. Uhlobo lweFayibha
Iintlobo zeFayibha zinokwahlulwa zibe yimowudi enye kunye neendlela ezininzi.Ubude obuphakathi bemodyuli ye-optical mode ye-single ngokuqhelekileyo yi-1310nm kunye ne-1550nm, kwaye zisetyenziswa kunye nemicu ye-optical yendlela enye.Ifayibha ye-Optical yemodi enye ine-frequency transmission frequency kunye nomthamo omkhulu wothumelo, kwaye ilungele ukuhanjiswa komgama omde.Ubude obuphakathi bemodyuli ye-multimode optical ngokubanzi yi-850nm, kwaye isetyenziswa kunye ne-multimode optical fiber.Ifiber ye-Multimode ineziphene ze-modal dispersion, kunye nokusebenza kwayo kokuhanjiswa kubi ngakumbi kune-fiber-mode-mode, kodwa ixabiso layo liphantsi, kwaye lifanelekile kumthamo omncinci kunye nokuhanjiswa kwexesha elifutshane.
2. I-Optical fiber interface
Ujongano lweemodyuli eziqhelekileyo ziquka iLC, SC, MPO, njl.
3. Ubushushu bokusebenza
Uluhlu lweqondo lokushisa olusebenzayo lwemodyuli ye-optical grade yorhwebo (0 ° C-70 ° C), ibakala elongeziweyo (-20 ° C-85 ° C), kunye nebakala lezoshishino (-40 ° C-85 ° C).Iimodyuli ze-Optical ezinephakheji efanayo, ireyithi, kunye nomgama wothumelo ngokuqhelekileyo zineenguqulelo ezimbini: ibakala lokuthengisa kunye nebakala lezoshishino.Iimveliso zodidi lwemizi-mveliso zisebenzisa izixhobo ezinokunyamezela ubushushu obungcono, ngoko ke ixabiso leemveliso zodidi lweshishini liphezulu.Kufuneka sikhethe umgangatho wokushisa wokusebenza wemodyuli ye-optical ngokwendawo yokusetyenziswa kwangempela.
4. Ukuhambelana kwesixhobo
Ngenxa yokuba abavelisi bezixhobo eziphambili, ukuze babonelele ngeemveliso kunye neenkonzo ezingaguqukiyo, bonke badla ngokuba ne-ecology evaliweyo.Ngoko ke, iimodyuli ze-optical azikwazi ukuxutywa kunye naluphi na uhlobo lwezixhobo.Xa sithenga imodyuli ye-optical, kufuneka sichaze kumthengisi ukuba zeziphi izixhobo imodyuli ye-optical kufuneka isetyenziswe kuyo, ukwenzela ukuba ugweme ingxaki yezixhobo ezingahambelaniyo kwimodyuli ye-optical.
5. Ixabiso
Ngokubanzi, iimodyuli ze-optical kunye ne-brand efanayo ne-brand yezixhobo ziyabiza.Ukusebenza kunye nomgangatho weemodyuli ze-optical party ezihambelanayo zinokuthi zifana neemodyuli ze-brand optical okwangoku, kodwa ixabiso linenzuzo ebonakalayo.
6. Umgangatho kunye nenkonzo emva kokuthengisa
Ngokuqhelekileyo, akuyi kubakho iingxaki kwiimodyuli ze-optical kunyaka wokuqala wokusetyenziswa, kwaye uninzi lwazo luya kubonakala kamva.Ngoko zama ukukhetha umthengisi onomgangatho ozinzile.
