Kwiitransceivers zefiber optical, umsebenzi ophambili we-transceiver kukwandisa umgama wothumelo lwenethiwekhi, enokunciphisa isiphene ukuba intambo yenethiwekhi ayikwazi ukuhambisa umgama omde ukuya kwinqanaba elithile, kwaye izise ukukhululeka kwi-kilometer yokugqibela, kodwa kulabo. Abatsha kwi-transceiver Ezinye zezona mpazamo zixhaphakileyo zenziwa ngabantu, njengokungacaciswa kwesiphelo sokudlulisa kunye nesiphelo sokufumana i-fiber optic. umdluliseli. Kutheni le nto ii-fiber optic transceivers zahlulwe zaba sisidluliseli kunye nomamkeli? Ngaba isiphelo se-A/B se-fiber optic transceiver sinokudityaniswa ngokungaqhelekanga?

I-ab end ye-fiber optic transceiver kufuneka ibe sisiphelo sokudlulisa (isiphelo) kunye nesiphelo sokufumana (b ekupheleni). Isizathu sokuba i-transceiver ihlulwe kwisiphelo sokudlulisa kwaye isiphelo sokufumana kukuba i-transceiver idinga ukuhambisa i-signal bidirectionally xa isetyenziswa, ngokuqhelekileyo ngababini. Abantu abaninzi basebenzisa ii-transceivers zefayibha enye kwimarike; Iziphelo ezimbini ze-fiber-fiber transceiver ziyi-A-end kunye ne-B-end ngokulandelanayo. Ubude bamaza kwezi ziphelo zibini zahlukile. Ubude bobude besiphelo sokudlulisa bufutshane kunobo bokufumana isiphelo. Enyanisweni, i-dual-fiber transceiver ayinayo i-A kunye ne-B iziphelo, kuba amaza amaza kwiziphelo zombini ayafana. Kuphela xa udibanisa i-TX (ukudlulisa) ukuphela kunye ne-RX (ukufumana) isiphelo, i-fiber enye, njengoko igama libonisa, i-fiber optical, kwaye ezinye iingcali ziyibiza ngokuba yi-transceiver eyodwa-core, ebhekisela ekuthumeleni nasekufumaneni Iimpawu kuzo zombini iziphelo kwifiber optical enye, kuba kwimowudi enye Imodyuli ye-optical esetyenziswa ngaphakathi kwe-fiber-fiber transceiver inamaza amabini okukhanya okukhutshiweyo, ngelixa I-dual-fiber idityaniswe ngokunqamlezileyo yimicu emibini ye-optical, kwaye ibhloko yefilimu yangaphakathi ye-optical yangaphakathi inobude obunye kuphela.

Ii-transceivers ze-fiber optical zihlulwe zibe yi-single-mode-dual-fiber optical fiber transceivers kunye ne-single-fiber optical fiber transceivers ngokwenani le-fiber cores. I-transceiver ye-fiber ye-single-mode ihanjiswa nge-fiber optical fiber, ngoko ke ukukhanya okugqithisiweyo kunye nokufunyenweyo kuhanjiswa ngocingo olulodwa lwe-fiber core ngexesha elifanayo.Kule meko, ukufezekisa unxibelelwano oluqhelekileyo, i-wavelengths ezimbini zokukhanya kufuneka zibe esetyenziselwa ukwahlula. Ngoko ke, imodyuli ye-optical mode ye-single-fiber transceiver ine-wavelengths ezimbini zokukhanya, ngokubanzi i-1310nm / 1550nm, kunye nomgama omde yi-1490nm / 1550nm. Ngale ndlela, kuya kubakho ukungafani phakathi kweziphelo ezimbini zokudityaniswa kwesibini se-transceivers, kwaye enye isiphelo se-transceiver iya kwahluka. Dlulisa i-1310nm kwaye ufumane i-1550nm. Esinye isiphelo kukusasaza i-1550nm kwaye ufumane i-1310nm. Ngoko kulula ukuba abasebenzisi bahlule, kwaye iileta zisetyenziswa ngokubanzi endaweni. Emva koko kukho i-a-end (1310nm/1550nm) kunye ne-B-end (1550nm/1310nm). Abasebenzisi kufuneka basebenzise i-ab pairing. Uqhagamshelwano lwe-Aa okanye lwe-bb aluvumelekanga.
