Sikholelwa ukuthi abasebenzisi abaningi banokuqonda okuthile kwama-optical transceiver. Abasebenzisi abaningi abazi okuningi ngamamojula optical. Amamojula we-Optical ayingxenye ebalulekile yama-transceivers optical. Amamojula we-Optical abaluleke kakhulu kuma-transceivers optical, ngakho-ke iyini imodyuli ye-optical futhi kungani ingadlala indima enkulu kangaka kuma-transceivers optical?

I-module optical ye-transceiver optical ngokuvamile isetshenziswa kunethiwekhi yomgogodla wenethiwekhi ye-fiber optical. Amamojula okukhanya ahlukaniswe kakhulu abe yi-GBIC, SFP, SFP+, XFP, SFF, CFP, njll., futhi izinhlobo ze-optical interface zifaka i-SC ne-LC. Kodwa-ke, i-SFP, SFP+, XFP isetshenziswa kakhulu namuhla esikhundleni se-GBIC. Isizathu ukuthi i-GBIC inkulu futhi iphuka kalula. Kodwa-ke, i-SFP evame ukusetshenziswa incane futhi ishibhile. Ngokusho kohlobo, ingahlukaniswa ngamamojula optical wemodi eyodwa kanye namamojula we-multi-mode optical. Amamojula we-optical mode eyodwa afanele ukudluliswa kwebanga elide; amamojula e-multi-mode optical afanele ukudluliswa kwebanga elifushane.

Imishini yokubona ithuthukela ekusetshenzisweni okuncane, ukuthuthukisa ukusebenza kahle (ukushintsha ugesi/i-optical, optical/electric), kanye nokwenza ngcono ukwethembeka; Ubuchwepheshe be-planar optical waveguide (PLC) buzoqhubeka nokunciphisa umthamo wezingxenye ze-bidirectional/three-directional optical futhi kuthuthukise ukwethembeka kwengxenye. Imisebenzi kanye nokusebenza kwama-chips wesifunda ahlanganisiwe kuye kwaqiniswa, ukuze umthamo wamamojula we-optical uncishiswe futhi ukusebenza kuye kwathuthukiswa ngokuqhubekayo. Uhlelo ngokuqhubekayo lubeka phambili izidingo ezintsha zemisebenzi eyengeziwe yemojuli, futhi umsebenzi ohlakaniphile wemojula ye-optical kumele uthuthukiswe ngokuqhubekayo ukuze uhlangabezane nezidingo zohlelo.

Eqinisweni, ku-transceiver optical, ukubaluleka kwemodyuli ye-optical kudlula kude i-chip core. Imodyuli ye-optical yakhiwe ngamadivaysi e-optoelectronic, ama-circuits asebenzayo kanye ne-optical interfaces. Kalula nje, indima ye-optical module ukuguqulwa kwe-photoelectric. Isiphetho sokudlulisa siguqula amasignali kagesi abe amasignali optical. Ngemuva kokudluliselwa nge-fiber optical, ukuphela kokuthola kuguqula izimpawu ze-optical zibe izimpawu zikagesi, ezisebenza kahle futhi eziphephile kunama-transceivers. Ngemva kokuba amandla evuliwe, imojula ye-optical isenqubweni yokukhipha ukukhanya njalo, futhi kuzoba nokuncipha ngokuhamba kwesikhathi. Ngakho-ke, kubaluleke kakhulu ukuthola umsebenzi we-optical module.

Kudingeka sisebenzise imitha yamandla okubona ukuze sithole ikhwalithi yemojuli ye-optical. Ngokuvamile, lapho i-optical module iphuma efekthri, umkhiqizi wangempela uzohambisa umbiko wokuhlolwa kwekhwalithi yale nqwaba kumkhiqizi ocutshungulwayo. Umkhiqizi usebenzisa imitha yamandla okubona ukuhlola kwangempela. , Uma umehluko ungaphakathi kwebanga lokubika, uwumkhiqizo ofanelekayo.

Ngevelu elihlolwe ngemojula yokubona, ububanzi bamandla embonini ngu-3~8dBm. Ngokuqhathanisa izinombolo, imojula ye-optical inganqunywa njengomkhiqizo ofanelekayo. Kukhunjuzwa ikakhulukazi ukuthi inani lamandla lincane, liyancipha amandla okuxhumana okubona; okungukuthi, i-low-power optical module ayikwazi ukwenza ukudluliselwa kwebanga elide. Ngokusho kwemithombo efanele embonini, amanye ama-workshops amancane azothenga amamojula e-second-hand optical, amanani awo avuselelwe futhi asetshenziswe emishinini yokudlulisa amehlo ekude. Ngokusobala, lokhu akunasibopho ngokwedlulele kubasebenzisi.
