Itekhnoloji yemodyuli ye-Optical, iintlobo kunye nokukhetha

一,Isishwankathelo sobugcisa beemodyuli zamehlo

Imodyuli ye-Optical, eyaziwa ngokuba yimodyuli edibeneyo ye-transceiver optical, iyona nxalenye ephambili kwinkqubo yonxibelelwano lwefiber optical. Baqaphela ukuguqulwa phakathi kwezibonakaliso ze-optical kunye neempawu zombane, ukuvumela idatha ukuba idluliselwe kwisantya esiphezulu kunye nemigama emide ngokusebenzisa i-fiber optical networks. Iimodyuli ze-Optical zenziwe ngezixhobo ze-optoelectronic, iisekethe, kunye ne-casings, kwaye zineempawu zesantya esiphezulu, ukusetyenziswa kwamandla aphantsi, kunye nokuthembeka okuphezulu. Kwiinethiwekhi zonxibelelwano zanamhlanje, iimodyuli ze-optical ziye zaba yinto ephambili yokufikelela kwi-high-speed data transmission kwaye isetyenziswa ngokubanzi kumaziko edatha, i-cloud computing, i-metropolitan area networks, i-backbone networks kunye nezinye iinkalo. Umgaqo osebenzayo wemodyuli ye-optical kukuguqula izibonakaliso zombane zibe yimpawu ze-optical, zidlulisele ngee-fibers optical, kwaye ziguqule iimpawu ze-optical kwizibonakaliso zombane ekupheleni kokufumana. Ngokukodwa, isiphelo sokudlulisa siguqula isignali yedatha kwisignali ye-optical kwaye idlulisele ekupheleni kokufumana nge-fiber optical, kwaye isiphelo sokufumana emva koko sibuyisela isignali ye-optical kwisignali yedatha. Kule nkqubo, imodyuli ye-optical iqonda ukuhanjiswa okufanayo kunye nokuhanjiswa kwexesha elide kwedatha.

二,Iindidi zeemodyuli zamehlo

1.Ukuhlelwa ngokwesantya:

Ngokwesantya, kukho i-155M/622M/1.25G/2.125G/4.25G/8G/10G. I-155M kunye ne-1.25G isetyenziswa kakhulu kwiimarike. Itekhnoloji ye-10G ikhula ngokuthe ngcembe, kwaye imfuno ikhula kwindlela ephezulu.

2.Ukuhlelwa ngokobude bobude:

Ngokobude be-wavelength, yahlulwe yaba yi-850nm/1310nm/1550nm/1490nm/1530nm/1610nm. Ubude be-850nm yi-SFP ye-multi-mode, kwaye umgama wokuhambisa ungaphantsi kwe-2KM. Ubude be-1310 / 1550nm yimowudi enye, kwaye umgama wokuhambisa ungaphezulu kwe-2KM.

3.Ukuhlelwa ngokwendlela:

(1）Iimowudi ezininzi: Phantse zonke iisayizi zefayibha ze-multimode ziyi-50/125um okanye i-62.5/125um, kunye ne-bandwidth (isixa solwazi oluhanjiswa yifayibha) idla ngokuba yi-200MHz ukuya kwi-2GHz. I-Multimode transceivers optical inokudlulisa ukuya kwiikhilomitha ezi-5 nge-Multimode optical fibers.

(2）Imowudi enye: Ubungakanani be-fiber ye-single-mode yi-9-10 / 125μm, kwaye ine-bandwidth engenamkhawulo kunye nokulahlekelwa okuphantsi kune-fiber mode multi-mode. Ii-transceivers zemowudi enye zisetyenziswa kakhulu kuthumelo lomgama omde, ngamanye amaxesha ukuya kuthi ga kwi-150 ukuya kwiikhilomitha ezingama-200.

三、 Iiparamitha zobugcisa kunye nezalathi zokusebenza

Xa ukhetha kwaye usebenzisa iimodyuli ze-optical, kufuneka uqwalasele ezi parameters zilandelayo zobugcisa kunye nezalathi zokusebenza:

1. Ilahleko yokufaka: Ilahleko yokufaka ibhekisela ekulahlekeni kwezibonakaliso ze-optical ngexesha lokudluliselwa kwaye kufuneka ibe yincinci kangangoko ukuqinisekisa umgangatho wesignali.

2. Ilahleko yokubuyisela: Ilahleko yokubuyisela ibhekisela ekubonakalisweni kokulahlekelwa kwezibonakaliso ze-optical ngexesha lokudluliselwa. Ilahleko yokubuyisela ngokugqithisileyo iya kuchaphazela umgangatho wesignali.

3. I-polarization mode dispersion: I-polarization mode dispersion ibhekisela kwi-dispersion ebangelwa yi-velocities yeqela elihlukeneyo leempawu ze-optical kwiimo ezahlukeneyo ze-polarization. Kufuneka ibe yincinci kangangoko ukuqinisekisa umgangatho wesignali.

4. I-Extinction ratio: I-extinction ratio ibhekisela kumahluko wamandla phakathi kwezinga eliphezulu kunye nenqanaba eliphantsi lesignali ye-optical. Kufuneka ibe yincinci kangangoko ukuqinisekisa umgangatho wesignali.

5. I-Digital diagnostic monitoring (DDM): Umsebenzi wokuhlola ukuxilongwa kwedijithali unokubeka iliso kwimeko yokusebenza kunye neeparitha zokusebenza zemodyuli ngexesha langempela ukuququzelela iingxaki kunye nokuphucula ukusebenza.
