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 zefayibha zanele, ungakhetha imodyuli yokubona ifayibha 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 ze-fiber ezimbini, oko kukuthi, i-fiber-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 imo enye kuphela; 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-single-mode iyahambelana. Azinakuxutywa.

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