Ukwanda okusheshayo kwamanethiwekhi e-fiber optic, okuhlanganisa nezinsizakalo zedatha ezilinganiswa ngevolumu yedatha noma i-bandwidth, kubonisa ukuthi ubuchwepheshe bokudlulisa i-fiber optic buyingxenye ebalulekile yezinhlelo zenethiwekhi zesikhathi esizayo futhi buzoqhubeka nokuba yingxenye ebalulekile yezinhlelo zenethiwekhi zesikhathi esizayo. Abaklami benethiwekhi bazizwa bekhululekile kakhulu ngezixazululo ze-fiber optic, njengoba ukusebenzisa izixazululo ze-fiber optic kwenza kube lula ukwakheka kwenethiwekhi okuguquguqukayo kanye nezinye izinzuzo ezifana nokuqina kwe-EMI (electromagnetic interference) kanye nokuphepha kwedatha. Ama-transceiver e-fiber optic adlala indima ebaluleke kakhulu kulezi zixhumanisi ze-fiber optic. Lapho uklama i-transceiver ye-fiber optic, kunezici ezintathu okufanele uzicabangele: izimo zemvelo, izimo zikagesi, kanye nokusebenza kwe-optical.
Iyini i-transceiver ye-fiber optic?
I-transceiver ye-fiber optic iyisakhi esizimele esithumela futhi samukele amasignali. Ngokuvamile, ixhuma kudivayisi enikeza izikhala zemojuli ye-transceiver eyodwa noma ngaphezulu, njenge-router noma ikhadi le-interface yenethiwekhi. I-transmitter ithatha okokufaka kukagesi bese iyiguqula ibe ukukhanya okuvela ku-laser diode noma i-LED. Ukukhanya okuvela ku-transmitter kuhlanganiswa ku-fiber ngesixhumi bese kudluliselwa ngedivayisi yekhebula le-fiber optic. Ukukhanya okuvela ekugcineni kwe-fiber bese kuhlanganiswa ne-receiver, lapho i-detector iguqula khona ukukhanya kube isignali kagesi, bese kuba yisimo esifanele sokusetshenziswa yidivayisi eyamukelayo.
Izinto Okucatshangwa Ngazo Ngokuklama
Izixhumanisi ze-fiber optic zingaphatha amazinga aphezulu edatha emabangeni amade uma kuqhathaniswa nezixazululo ze-copper wire, okuye kwaholela ekusetshenzisweni kabanzi kwama-transceivers e-fiber optic. Lapho kuklanywa ama-transceivers e-fiber optic, izici ezilandelayo kufanele zicatshangelwe.
Isimo semvelo
Inselele eyodwa ivela esimweni sezulu sangaphandle—ikakhulukazi isimo sezulu esibi ezindaweni eziphakeme noma ezivezwe obala. Lezi zingxenye kumele zisebenze ngaphansi kwezimo zemvelo ezimbi kakhulu kanye nobubanzi bokushisa obubanzi. Ukukhathazeka kwesibili kwemvelo okuhlobene nomklamo we-transceiver ye-fiber optic yindawo ye-motherboard ehlanganisa ukusetshenziswa kwamandla esistimu kanye nezici zokushisa.
Inzuzo enkulu yama-transceivers e-fiber optic izidingo zawo zamandla kagesi eziphansi kakhulu. Kodwa-ke, lokhu kusetshenziswa kwamandla aphansi akusho ukuthi ukwakheka kokushisa kungashaywa indiva lapho kuhlanganiswa ukucushwa komsingathi. Umoya ohlanzekile noma ukuhamba komoya okwanele kufanele kufakwe ukusiza ukuqeda amandla okushisa akhishwa kumojuli. Ingxenye yalesi sidingo ihlangatshezwa yikheji le-SFP elijwayelekile elifakwe kubhodi lomama, elisebenza futhi njengomsele wamandla okushisa. Izinga lokushisa lecala elibikwe yi-Digital Monitor Interface (DMI) lapho i-mainframe isebenza ekushiseni kwayo okuphezulu kokuklama kuyisilingo sokugcina sokusebenza kahle komklamo wokushisa wohlelo lonke.
Izimo zikagesi
Empeleni, i-transceiver ye-fiber optic iyidivayisi kagesi. Ukuze kugcinwe ukusebenza okungenamaphutha kwedatha edlula kumojuli, ukunikezwa kwamandla kumojuli kumele kuzinzile futhi kungabi nomsindo. Okubaluleke kakhulu, ukunikezwa kwamandla okushayela i-transceiver kumele kuhlungwe kahle. Izihlungi ezijwayelekile zichazwe ku-Multi-Source Agreement (MSA), eyaqondisa ukwakheka kokuqala kwala ma-transceiver. Umklamo owodwa onjalo ku-SFF-8431 specification uboniswe ngezansi.
Izakhiwo ezibonakalayo
Ukusebenza kwe-Optical kulinganiswa ngesilinganiso sephutha le-bit noma i-BER. Inkinga ngokuklama i-transceiver ye-optical ukuthi amapharamitha e-optical e-transmitter kanye ne-receiver kumele alawulwe ukuze noma yikuphi ukuncishiswa okungenzeka kwesignali ye-optical njengoba ihamba phansi kwe-fiber kungabangela ukusebenza okubi kwe-BER. Ipharamitha eyinhloko ethakazelisayo yi-BER yesixhumanisi esiphelele. Okusho ukuthi, indawo yokuqala yesixhumanisi ingumthombo wesignali kagesi eqhuba i-transmitter, futhi ekugcineni, isignali kagesi yamukelwa yi-receiver futhi ihunyushwe yi-circuitry ku-host. Kulezo zixhumanisi zokuxhumana ezisebenzisa ama-transceiver e-optical, umgomo oyinhloko ukuqinisekisa ukusebenza kwe-BER phezu kwamabanga ahlukene ezixhumanisi nokuqinisekisa ukusebenzisana okubanzi nama-transceiver eqembu lesithathu avela kubathengisi abahlukene.
