Iimodyuli ze-Optical kunye ne-optical fiber transceivers zizixhobo ezenza ukuguqulwa kwe-photoelectric. Yintoni umahluko phakathi kwazo? Kule mihla, ukuhanjiswa kwedatha kumgama omde osetyenziswa kwiiprojekthi ezininzi ezihlakaniphile ngokusisiseko kusebenzisa ukuhanjiswa kwefiber optical. Ukudibanisa phakathi koku kufuna iimodyuli ze-optical kunye ne-fiber optic transceivers. Ngoko ke, ezi zimbini zifanele zidityaniswe njani, kwaye yintoni efanele iqwalaselwe?
1. Imodyuli yokubona
Umsebenzi wemodyuli ye-optical kwakhona ukuguqulwa phakathi kwezibonakaliso ze-photoelectric. Isetyenziswa ikakhulu kumthwali phakathi kwetshintshakunye nesixhobo. Inomgaqo ofanayo kunye ne-transceiver ye-fiber optical, kodwa imodyuli ye-optical iyasebenza kwaye ikhuselekile kune-transceiver. Iimodyuli ze-optical zihlelwa ngokwefom yephakheji. Eziqhelekileyo ziquka i-SFP, SFP +, XFP, SFP28, QSFP +, QSFP28, njl.
2. I-Optical fiber transceiver
I-Optical fiber transceiver sisixhobo esiguqula imiqondiso yombane ekude kunye nemiqondiso yokubona ekude. Ngokuqhelekileyo isetyenziselwa ukuhanjiswa kwexesha elide, ukuhanjiswa ngeefibers ze-optical, ukuguqula izibonakaliso zombane zibe zizibonakaliso ze-optical kunye nokuzithumela. Isignali ye-optical efunyenweyo iguqulwa ibe ngumqondiso wombane. Ikwabizwa ngokuba yiFiber Converter kwiindawo ezininzi.
I-Fiber optic transceivers ibonelela ngesisombululo esingabizi kakhulu kubasebenzisi abafuna ukuphucula inkqubo ukusuka kwintambo yobhedu ukuya kwi-fiber optics, kodwa bengenamali, abasebenzi okanye ixesha.
3. Umahluko phakathi kwemodyuli ye-optical kunye ne-transceiver fiber optical
① Iyasebenza kwaye isenziwa: Imodyuli yokubona yimodyuli esebenzayo, okanye isincedisi, sisixhobo esingenakwenziwa esingenakusetyenziswa sodwa, kwaye sisetyenziswa kuphelaiiswitshikunye nezixhobo ezineendawo zokubeka iimodyuli ze-optical; iitransceivers zefiber optical zizixhobo ezisebenzayo. Sisixhobo esisebenzayo esahlukileyo, esinokusetyenziswa sodwa xa siplagiwe;
②Ukuphuculwa koqwalaselo: Imodyuli ye-optical ixhasa ukutshintshana okushushu, uqwalaselo lunoguquguqukayo; i-transceiver ye-fiber optical iqinisiwe, kwaye ukutshintshwa kunye nokuphucula kuya kuba nzima ngakumbi;
③Ixabiso: Iitransceiver zefayibha zamehlo zinexabiso eliphantsi kuneemodyuli zamehlo kwaye zinoqoqosho kwaye ziyasebenza, kodwa zikwafuna ukuqwalasela izinto ezininzi ezinje ngeadaptha yamandla, ubume bokukhanya, ubume bentambo yenethiwekhi, njalo njalo, kunye neeakhawunti zelahleko zothumelo malunga ne-30%;
④Isicelo: Iimodyuli ze-Optical zisetyenziswa ikakhulu kwisixhobo sonxibelelwano sothungelwano lwe-optical network, njenge-optical interfaces of aggregation.iiswitshi, undoqoiirotha, DSLAM,OLTkunye nezinye izixhobo, ezinje: ividiyo yekhompyuter, unxibelelwano lwedatha, unxibelelwano lwezwi olungenazingcingo kunye nomqolo we-fiber optical network; I-fiber optical transceiver Isetyenziselwa kwindawo yenethiwekhi yangempela apho intambo ye-Ethernet ayikwazi ukugubungela kwaye kufuneka isebenzise i-fiber optical ukwandisa umgama wokudlulisa, kwaye ngokuqhelekileyo ibekwe njengesicelo somgca wokufikelela kwinethiwekhi ye-broadband ye-metropolitan;
4. Yintoni ekufuneka ihlawulwe ingqalelo xa udibanisa imodyuli ye-optical kunye ne-transceiver fiber optical?
① Isantya semodyuli ye-optical kunye ne-transceiver ye-fiber optical kufuneka ifane, i-100 ye-megabytes ukuya kwi-100 megabytes, i-gigabit ukuya kwi-gigabit, kunye ne-10 ye-megabytes ukuya kwi-10 yetriliyoni.
② Umgama wamaza kunye nomgama wothumelo kufuneka uhambelane, umzekelo, ubude be-waveleng yi-1310nm okanye i-850nm ngexesha elinye, kwaye umgama wothumelo yi-10km;
③ Uhlobo lokukhanya kufuneka lufane, ifayibha enye ukuya kwifayibha enye, ifayibha ezimbini ukuya kwifayibha ezimbini.
④ Izijumpi zeFayibha okanye imisila yehagu kufuneka idityaniswe ngojongano olufanayo. Ngokuqhelekileyo, i-fiber optic transceivers isebenzisa izibuko ze-SC kunye neemodyuli ze-optical zisebenzisa izibuko ze-LC.
