Ukwanda okusheshayo kwamanethiwekhi e-fiber optic, okuhlanganisa nezinsizakalo zedatha ezilinganiswa ngevolumu yedatha noma umkhawulokudonsa, kubonisa ukuthi ubuchwepheshe bokudlulisa i-fiber optic buyingxenye ebalulekile yezinhlelo zenethiwekhi zesikhathi esizayo futhi buzoqhubeka buyingxenye ebalulekile yezinhlelo zenethiwekhi zesikhathi esizayo.Abaklami benethiwekhi baya ngokuya benethezeka ngezixazululo ze-fiber optic, njengoba ukusebenzisa izixazululo ze-fiber optic kuvumela izakhiwo zenethiwekhi ezivumelana nezimo nezinye izinzuzo ezifana nokuqina kwe-EMI (i-electromagnetic interference) nokuphepha kwedatha.Ama-transceivers e-fiber optic adlala indima ebaluleke kakhulu kulokhu kuxhumana kwe-fiber optic.Lapho uklama i-fiber optic transceiver, kunezici ezintathu okufanele zicatshangelwe: izimo zemvelo, izimo zikagesi, nokusebenza kokubona.
Iyini i-fiber optic transceiver?
I-fiber optic transceiver iyingxenye ezimele ehambisa futhi yamukele amasignali.Ngokuvamile, ixhuma kudivayisi ehlinzeka ngesikhala semojuli ye-transceiver eyodwa noma ngaphezulu, njengerutha noma ikhadi lesixhumi esibonakalayo senethiwekhi.I-transmitter ithatha okokufaka kukagesi futhi ikuguqulele ekuphumeni kokukhanya kusuka ku-laser diode noma i-LED.Ukukhanya okuvela kusidlulisi kuhlanganiswa ku-fiber ngesixhumi futhi kudluliselwa ngedivayisi yentambo ye-fiber optic.Ukukhanya okuvela ekugcineni kwefayibha kube sekuhlanganiswe nesamukeli, lapho umtshina uguqula ukukhanya kube isignali kagesi, ebese ifakwa esimweni esifanele ukuze sisetshenziswe idivayisi eyamukelayo.
Ukucatshangelwa kokuklama
Izixhumanisi ze-Fiber optic zingakwazi ngempela ukuphatha amanani edatha aphezulu kumabanga amade uma kuqhathaniswa nezixazululo zezintambo zethusi, okuqhubekisele phambili ukusetshenziswa okubanzi kwama-transceiver e-fiber optic.Lapho uklama ama-transceivers e-fiber optic, izici ezilandelayo kufanele zibhekwe.
Isimo semvelo
Inselele eyodwa ivela esimweni sezulu sangaphandle—ikakhulukazi isimo sezulu esibi ezindaweni eziphakeme noma ezisobala.Lezi zingxenye kufanele zisebenze ngaphansi kwezimo ezibucayi zemvelo kanye nebanga lokushisa elibanzi.Ukukhathazeka kwesibili kwezemvelo okuhlobene nomklamo we-fiber optic transceiver imvelo yebhodi lomama ehlanganisa ukusetshenziswa kwamandla esistimu nezici ezishisayo.
Inzuzo enkulu yama-fiber optic transceivers yizidingo zawo zamandla kagesi aphansi.Kodwa-ke, lokhu kusetshenziswa kwamandla okuphansi akusho ngokuqondile ukuthi idizayini eshisayo ingashaywa indiva lapho kuhlanganiswa ukulungiselelwa komsingathi.Ukungenisa umoya okwanele noma ukugeleza komoya kufanele kufakwe ukuze kusize ukuqeda amandla ashisayo akhishwe kumojula.Ingxenye yale mfuneko ihlangatshezwana nekheji elimisiwe le-SFP elifakwe ebhodini lomama, eliphinde lisebenze njengepayipi lamandla ashisayo.Izinga lokushisa lekesi elibikwe i-Digital Monitor Interface (DMI) lapho uhlaka oluyinhloko lusebenza ezingeni lokushisa eliphezulu lokuklama kwalo kuwukuhlola okuphelele kokusebenza kwedizayini yokushisa yesistimu iyonke.
Izimo zikagesi
Empeleni, i-fiber optic transceiver iyisisetshenziswa sikagesi.Ukuze kugcinwe ukusebenza okungenaphutha kwedatha edlula kumojuli, ukunikezwa kwamandla kumojuli kufanele kuzinze futhi kungabi namsindo.Okubaluleke nakakhulu, amandla ashayela i-transceiver kufanele ahlungwe kahle.Izihlungi ezijwayelekile zicaciswe ku-Multi-Source Agreement (MSA), eqondise umklamo wangempela walawa ma-transceivers.Umklamo owodwa onjalo ekucacisweni kwe-SFF-8431 kukhonjisiwe ngezansi.
Izakhiwo ze-Optical
Ukusebenza kokubona kukalwa ngesilinganiso sephutha elincane noma BER.Inkinga ngokuklama i-transceiver ebonakalayo ukuthi imingcele ye-optical ye-transmitter ne-receiver kumele ilawulwe ukuze noma yikuphi ukuncishiswa okungenzeka kwesiginali ye-optical njengoba ihamba phansi kwe-fiber kungaphumeleli ekusebenzeni kabi kwe-BER.Ipharamitha eyinhloko yentshisekelo yi-BER yesixhumanisi esiphelele.Okusho ukuthi, indawo yokuqala yesixhumanisi ingumthombo wesignali kagesi eshayela umthumeli, futhi ekugcineni, isignali kagesi yamukelwa umamukeli futhi ihunyushwa yi-circuitry in the host.Kulezo zixhumanisi zokuxhumana ezisebenzisa ama-transceiver optical, umgomo oyinhloko uwukuqinisekisa ukusebenza kwe-BER emabangeni ahlukene okuxhumanisa nokuqinisekisa ukusebenzisana okubanzi nama-transceiver ezinkampani zangaphandle avela kubathengisi abahlukene.
