Kwiitransceivers zamehlo, nokuba ifayibha enye okanye ifayibha ezimbini zingcono, masiqale siqonde ukuba yeyiphi ifayibha enye kunye nefiber ezimbini.

Ifiber enye: Idatha efunyenweyo kwaye ithunyelwe ihanjiswa kwifiber enye ye-optical.
Ifayibha ezimbini: Idatha efunyenweyo kwaye ithunyelwe ihanjiswa kwiifibers ezingundoqo ezimbini ngokulandelelanayo.

Iimodyuli ze-fiber-fiber bidirectional optical zibiza kakhulu, kodwa zinokugcina enye i-fiber resource, eyona nto ingcono kubasebenzisi abanemithombo yefiber eyaneleyo.
Imodyuli ye-fiber bidirectional optical module inexabiso eliphantsi, kodwa ifayibha enye iyafuneka.Ukuba izibonelelo zefiber zanele, ungakhetha imodyuli ye-fiber optical ezimbini.

Ke ubuyela kumbuzo wangaphambili, ngaba ifayibha enye okanye ifayibha ezimbini zingcono kwi-transceiver ebonakalayo?

Ii-transceivers ze-fiber optical ze-single-fiber zingagcina isiqingatha semithombo ye-fiber cable, oko kukuthi, ukuhanjiswa kwedatha kunye nokwamkelwa kwi-fiber-core fiber, efanelekileyo kakhulu kwiindawo apho izibonelelo zefiber ziqinile;ngelixa i-transceivers optical double-fiber kufuneka ithathe i-fiber optical fiber, enye i-core isetyenziselwa ukuhanjiswa (Tx) I-core enye isetyenziselwa ukufumana (Rx).Ubude obuqhelekileyo be-fiber optical transceivers yi-1310nm kunye ne-1550nm yokusetyenziswa ngababini, oko kukuthi, enye isiphelo yi-1310 wavelength, kwaye enye isiphelo yi-1550 wavelength, enokuthumela okanye ukufumana.

Ii-transceivers ze-fiber optical ezimbini zine-uniform wavelength, oko kukuthi, izixhobo kuzo zombini iziphelo zisebenzisa ubude obufanayo.Nangona kunjalo, kuba akukho mgangatho odibeneyo wamazwe ngamazwe weemveliso ze-optical transceiver, kunokubakho ukungahambelani phakathi kweemveliso zabenzi abahlukeneyo xa zidibene.Ukongezelela, ngenxa yokusetyenziswa kwe-multiplexing ye-wavelength division, iimveliso ze-fiber optical transceiver zineengxaki zokunciphisa umqondiso, kwaye ukuzinza kwabo kubi kakhulu kuneemveliso ezimbini ze-fiber, oko kukuthi, i-fiber optical transceivers ineemfuno eziphezulu kwiimodyuli ze-optical, ngoko ke ii-transceivers ze-fiber-optical optical kwimarike ngokwentelekiso zi-Dual-fiber optical transceivers nazo zibiza kakhulu.

I-transceiver ye-multi-mode ifumana iindlela zokuhambisa ezininzi, umgama wokuhambisa ufutshane, kwaye i-transceiver ye-mode eyodwa ifumana kuphela imodi enye;umgama wothumelo mde ngokwentelekiso.Nangona i-multi-mode ichithwa, kusekho izicelo ezininzi ekubekweni iliso kunye nokuhanjiswa komgama omfutshane ngenxa yexabiso eliphantsi.Ii-transceivers ze-multi-mode zihambelana ne-multi-mode fibers, kwaye i-mode-mode kunye ne-mode eyodwa iyahambelana.Azinakuxutywa.

Okwangoku, uninzi lwe-transceivers optical kwimarike zizinto ezimbini-fiber, ezikhulileyo kwaye zizinzile, kodwa zifuna izixhobo ezingaphezulu zentambo ye-optical.
