Ubuchwepheshe bemojula ye-Optical, izinhlobo nokukhetha

一,Ukubuka konke kobuchwepheshe kwamamojula okubona

I-Optical module, eyaziwa nangokuthi i-optical transceiver integrated module, iyingxenye eyinhloko ohlelweni lokuxhumana lwe-fiber optical. Baqaphela ukuguqulwa phakathi kwamasignali optical namasignali kagesi, okuvumela idatha ukuthi idluliselwe ngesivinini esikhulu kanye namabanga amade ngamanethiwekhi optical fiber. Amamojula we-Optical akhiwe ngamadivayisi we-optoelectronic, amasekhethi, nama-casings, futhi anezici zejubane eliphezulu, ukusetshenziswa kwamandla okuphansi, nokuthembeka okuphezulu. Kumanethiwekhi okuxhumana anamuhla, amamojula optical abe yingxenye ebalulekile yokufeza ukudluliswa kwedatha ngesivinini esikhulu futhi asetshenziswa kabanzi ezikhungweni zedatha, i-cloud computing, amanethiwekhi wendawo yedolobha elikhulu, amanethiwekhi omgogodla kanye nezinye izinkambu. Isimiso sokusebenza semodyuli ye-optical ukuguqula amasignali kagesi abe amasignali optical, uwadlulisele ngokusebenzisa imicu ye-optical, futhi uguqule amasignali optical abe amasignali kagesi ekugcineni kokuthola. Ngokukhethekile, isiphetho sokudlulisa siguqula isignali yedatha ibe isignali yokubona futhi iyidlulisele ekugcineni kokwamukela nge-fiber optical, bese isiphetho sokwamukela bese sibuyisela isignali yokubona kusignali yedatha. Kule nqubo, imojula ye-optical ibona ukudluliswa okufanayo kanye nokudluliswa kwedatha ebangeni elide.

二,Izinhlobo zamamojula optical

1.Ukuhlelwa ngesivinini:

Ngokwejubane, kukhona 155M/622M/1.25G/2.125G/4.25G/8G/10G. I-155M ne-1.25G isetshenziswa kakhulu emakethe. Ubuchwepheshe be-10G bukhula kancane kancane, futhi isidingo sikhula ngendlela ekhuphukayo.

2.Ukuhlukaniswa nge-wavelength:

Ngokwe-wavelength, ihlukaniswe yaba ngu-850nm/1310nm/1550nm/1490nm/1530nm/1610nm. Ubude begagasi be-850nm yi-SFP multi-mode, futhi ibanga lokudlulisela lingaphansi kuka-2KM. Ubude begagasi be-1310/1550nm yimodi eyodwa, futhi ibanga lokudlulisela lingaphezu kuka-2KM.

3.Ukuhlukaniswa ngemodi:

(1）Imodi eningi: Cishe bonke osayizi befayibha ye-multimode bangu-50/125um noma 62.5/125um, futhi umkhawulokudonsa (inani lolwazi oludluliswa yifayibha) ngokuvamile ngu-200MHz ukuya ku-2GHz. Ama-transceiver abonakalayo e-Multimode angadlulisa amakhilomitha afinyelela ku-5 nge-Multimode optical fibers.

(2）Imodi eyodwa: Usayizi we-fiber yemodi eyodwa ngu-9-10/125μm, futhi unomkhawulokudonsa ongenamkhawulo nokulahlekelwa okuphansi kune-multi-mode fiber. Ama-transceiver optical emodi eyodwa asetshenziswa kakhulu ekudluliseleni ibanga elide, kwesinye isikhathi kufika kumakhilomitha ayi-150 kuye kwangama-200.

三、 Amapharamitha wobuchwepheshe nezinkomba zokusebenza

Lapho ukhetha futhi usebenzisa amamojula optical, udinga ukucabangela imingcele elandelayo yezobuchwepheshe nezinkomba zokusebenza:

1. Ukulahlekelwa kokufaka: Ukulahlekelwa kokufaka kubhekisela ekulahlekelweni kwamasignali okubona ngesikhathi sokudlulisa futhi kufanele kube kuncane ngangokunokwenzeka ukuze kuqinisekiswe ikhwalithi yesignali.

2. Ukulahlekelwa kokubuyisela: Ukulahlekelwa kokubuyisela kubhekisela ekulahlekelweni kokuboniswa kwamasignali optical phakathi nokudlulisa. Ukulahlekelwa kwembuyiselo ngokweqile kuzothinta ikhwalithi yesiginali.

3. Ukuhlakazeka kwemodi ye-polarization: Ukuhlakazeka kwemodi ye-polarization kubhekisela ekuhlakazweni okubangelwa isivinini seqembu esihlukile samasignali optical ezifundeni ezihlukahlukene ze-polarization. Kufanele kube kuncane ngangokunokwenzeka ukuze kuqinisekiswe ikhwalithi yesignali.

4. Isilinganiso sokuqothula: Isilinganiso sokuqothulwa sibhekisela kumehluko wamandla phakathi kwezinga eliphezulu nezinga eliphansi lesignali yokubona. Kufanele kube kuncane ngangokunokwenzeka ukuze kuqinisekiswe ikhwalithi yesignali.

5. Ukuqapha kokuxilonga kwedijithali (i-DDM): Umsebenzi wokuqapha ukuxilonga wedijithali ungaqapha isimo sokusebenza kanye nemingcele yokusebenza yemojuli ngesikhathi sangempela ukuze kube lula ukuxazulula izinkinga kanye nokwenza kahle kokusebenza.

四、Izixwayiso zokukhetha nokusebenzisa

Lapho ukhetha futhi usebenzisa amamojula optical, udinga ukunaka lezi zinto ezilandelayo:

1. Ukucaciswa kwe-fiber optical: Amamojula afana ne-optical fiber yangempela esetshenzisiwe kufanele akhethwe ukuze kuqinisekiswe umphumela ongcono kakhulu wokudlulisela.

2. Indlela yokudokha: Imojuli kufanele ikhethwe ukuze ifane nesixhumi esibonakalayo sedivayisi sangempela ukuze kuqinisekiswe ukudotshwa okulungile nokudluliswa okuzinzile.

3. Ukuhambisana: Amamojula ahambisana nedivayisi yangempela kufanele akhethwe ukuze kuqinisekiswe ukuhambisana okuhle nokuzinza.

4. Izici zemvelo: Umthelela wezici zemvelo ezifana nezinga lokushisa kanye nomswakama endaweni yokusetshenziswa kwangempela ekusebenzeni kwamamojula kufanele kucatshangelwe.

5. Ukunakekela kanye nokunakekelwa: Imojula kufanele ihlolwe futhi inakekelwe njalo ukuze kuqinisekiswe ukusebenza kwayo okuzinzile kwesikhathi eside.
