Ukwanda ngokukhawuleza kweenethiwekhi ze-fiber optic, kuquka iinkonzo zedatha ezilinganiswa ngomthamo wedatha okanye i-bandwidth, kubonisa ukuba iteknoloji yokudlulisa i-fiber optic iyinxalenye ebalulekileyo kwaye iya kuqhubeka nokuba yinxalenye ebalulekileyo yeenkqubo zenethiwekhi zexesha elizayo. Abayili benethiwekhi bayakhululeka ngakumbi ngezisombululo ze-fiber optic, njengoko ukusebenzisa izisombululo ze-fiber optic kwenza kube lula ukwakhiwa kwenethiwekhi okuguquguqukayo kunye nezinye izibonelelo ezifana nokuqina kwe-EMI (electromagnetic interference) kunye nokhuseleko lwedatha. Ii-transceivers ze-fiber optic zidlala indima ebaluleke kakhulu kwezi nxibelelwano ze-fiber optic. Xa uyila i-transceiver ye-fiber optic, kukho iinkalo ezintathu ekufuneka ziqwalaselwe: iimeko zokusingqongileyo, iimeko zombane, kunye nokusebenza kwe-optical.
Yintoni i-fiber optic transceiver?
I-transceiver ye-fiber optic yinxalenye ezimeleyo ethumela kwaye ifumane imiqondiso. Ngokwesiqhelo, ixhuma kwisixhobo esinika indawo enye okanye ezingaphezulu ze-transceiver module, njenge-router okanye ikhadi le-network interface. I-transmitter ithatha igalelo lombane kwaye iyiguqulele ekukhanyeni okuvela kwi-laser diode okanye i-LED. Ukukhanya okuvela kwi-transmitter kudityaniswa kwi-fiber nge-connector kwaye kudluliselwe ngesixhobo sekhebula le-fiber optic. Ukukhanya okuvela esiphelweni se-fiber emva koko kudityaniswa ne-receiver, apho i-detector iguqula ukukhanya kube yisignali yombane, ethi emva koko ilungiswe ngokufanelekileyo ukuze isetyenziswe sisixhobo esamkelayo.
Izinto eziqwalaselwayo kuYilo
Iikhonkco ze-fiber optic zinokusingatha amazinga aphezulu edatha kumgama omde xa kuthelekiswa nezisombululo ze-copper wire, nto leyo eye yabangela ukusetyenziswa ngokubanzi kwee-transceivers ze-fiber optic. Xa kuyilwa ii-transceivers ze-fiber optic, kufuneka kuqwalaselwe ezi zinto zilandelayo.
Imeko yokusingqongileyo
Omnye umngeni uvela kwimozulu engaphandle—ingakumbi imozulu embi kwiindawo eziphakamileyo okanye ezibonakala kakhulu. Ezi zinto kufuneka zisebenze phantsi kweemeko ezibi kakhulu zendalo kunye nobushushu obuphezulu. Ingxaki yesibini yendalo enxulumene noyilo lwe-transceiver ye-fiber optic yindawo ye-motherboard equka ukusetyenziswa kwamandla enkqubo kunye neempawu zobushushu.
Inzuzo enkulu yee-transceivers ze-fiber optic kukuba zifuna amandla ombane aphantsi kakhulu. Nangona kunjalo, ukusetyenziswa kwamandla aphantsi akuthethi ukuba uyilo lobushushu lunokungahoywa xa kuhlanganiswa ulungelelwaniso lomsingathi. Umoya okanye ukuhamba komoya okwaneleyo kufuneka kufakwe ukunceda ukukhupha amandla obushushu akhutshwa kwimodyuli. Inxalenye yale mfuneko ifezekiswa yikheyiji ye-SFP esemgangathweni efakwe kwi-motherboard, esebenza njenge-conduit yamandla obushushu. Ubushushu becala obuxelwe yiDigital Monitor Interface (DMI) xa i-mainframe isebenza kubushushu bayo obuphezulu lolona vavanyo lokugqibela lokusebenza koyilo lobushushu benkqubo iyonke.
Iimeko zombane
Ngokwenyani, i-transceiver ye-fiber optic sisixhobo sombane. Ukuze idatha edlula kwimodyuli ihlale isebenza ngaphandle kwempazamo, umbane oya kwimodyuli kufuneka uhlale uzinzile kwaye ungabi nangxolo. Okubaluleke ngakumbi, umbane oqhuba i-transceiver kufuneka uhluzwe ngokufanelekileyo. Izihluzo eziqhelekileyo zichazwe kwiSivumelwano seMithombo emininzi (MSA), esasikhokela uyilo lokuqala lwezi transceivers. Uyilo olunye olunjalo kwi-SFF-8431 specifications luboniswe ngezantsi.
Iimpawu ezibonakalayo
Ukusebenza kwe-Optical kulinganiswa ngesantya sempazamo ye-bit okanye i-BER. Ingxaki yokuyila i-transceiver ye-optical kukuba iiparameter ze-optical ze-transmitter kunye ne-receiver kufuneka zilawulwe ukuze naluphi na ukuncipha okunokwenzeka kwesignali ye-optical njengoko ihamba kwi-fiber kungabangela ukusebenza kakubi kwe-BER. Ipharamitha ephambili enomdla yi-BER yekhonkco elipheleleyo. Oko kukuthi, indawo yokuqala yekhonkco ngumthombo wesignali yombane eqhuba i-transmitter, kwaye ekugqibeleni, uphawu lombane lufunyanwa yi-receiver kwaye lutolikwe yi-circuitry kwi-host. Kwezo linki zonxibelelwano ezisebenzisa ii-transceivers ze-optical, injongo ephambili kukuqinisekisa ukusebenza kwe-BER kumgama owahlukeneyo wekhonkco kunye nokuqinisekisa ukusebenzisana okubanzi nee-transceivers zangaphandle ezivela kubathengisi abahlukeneyo.
