Ukwandiswa ngokukhawuleza kwe-fiber optic networks, kubandakanywa neenkonzo zedatha ezilinganiswe kumthamo wedatha okanye i-bandwidth, ibonisa ukuba iteknoloji yokuhambisa i-fiber optic kwaye iya kuqhubeka iyingxenye ebalulekileyo yeenkqubo zenethiwekhi ezizayo.Abaqulunqi benethiwekhi baya bekhululeka ngakumbi kwizisombululo zefiber optic, njengoko ukusebenzisa izisombululo zefiber optic zenza ulwakhiwo lwenethiwekhi olubhetyebhetye kunye nezinye izibonelelo ezinje nge-EMI (ukuphazamiseka kombane) kunye nokhuseleko lwedatha.I-Fiber optic transceivers idlala indima ebaluleke kakhulu kolu qhagamshelwano lwefiber optic.Xa uyila i-fiber optic transceiver, kukho imiba emithathu ekufuneka iqwalaselwe: iimeko zokusingqongileyo, iimeko zombane, kunye nokusebenza kwamehlo.
Yintoni i-fiber optic transceiver?
I-fiber optic transceiver licandelo elizimeleyo elithumela kwaye lifumana iimpawu.Ngokuqhelekileyo, iplagi kwisixhobo esibonelela ngeendawo zokubeka imodyuli enye okanye ngaphezulu, njenge-router okanye ikhadi lojongano lwenethiwekhi.I-transmitter ithatha igalelo lombane kwaye iyiguqulele ekuphumeni okukhanyayo kwi-laser diode okanye i-LED.Ukukhanya okuvela kwi-transmitter kudityaniswa kwifayibha ngesidibanisi kwaye kuhanjiswe ngesixhobo sentambo yefiber optic.Ukukhanya okuvela ekupheleni kwefayibha kudityaniswa kwi-receiver, apho i-detector iguqula ukukhanya ibe ngumqondiso wombane, othi ke ulungiswe ngokufanelekileyo ukuba usetyenziswe sisixhobo esifumanayo.
Iingqwalasela zoyilo
Amakhonkco eFiber optic ngokwenene anokuphatha amaxabiso aphezulu edatha kumgama omde xa kuthelekiswa nezisombululo zocingo lobhedu, eziqhube ukusetyenziswa ngokubanzi kweetransceivers zefiber optic.Xa uyila i-fiber optic transceivers, le miba ilandelayo kufuneka ithathelwe ingqalelo.
Imeko yokusingqongileyo
Olunye ucelomngeni luvela kwimozulu yangaphandle—ingakumbi imozulu embi kwindawo ephakamileyo okanye evulelekileyo.La macandelo kufuneka asebenze phantsi kweemeko ezinzulu zokusingqongileyo kunye noluhlu olubanzi lobushushu.Inkxalabo yesibini yokusingqongileyo enxulumene noyilo lwe-fiber optic transceiver yindawo yebhodi ye-motherboard ebandakanya ukusetyenziswa kwamandla enkqubo kunye neempawu zokushisa.
Inzuzo enkulu yee-fiber optic transceivers ziimfuno zabo zamandla ombane aphantsi.Nangona kunjalo, oku kusetyenziswa kwamandla aphantsi akuthethi ncam ukuba uyilo lwe-thermal lunokungahoywa xa uhlanganisa ulungelelwaniso lomamkeli.Ukungena komoya okwaneleyo okanye ukuhamba komoya kufuneka kufakwe ukunceda ukukhupha amandla ashushu agxothwe kwimodyuli.Inxalenye yale mfuno idibene ne-SFP cage esemgangathweni efakwe kwi-motherboard, ekwasebenza njenge-conduit yamandla e-thermal.Iqondo lokushisa elichazwe yi-Digital Monitor Interface (DMI) xa i-mainframe isebenza kwiqondo lokushisa eliphezulu loyilo lolona vavanyo lokugqibela lokusebenza kwenkqubo yoyilo lwe-thermal.
Iimeko zombane
Ngokusisiseko, i-fiber optic transceiver sisixhobo sombane.Ukuze kugcinwe ukusebenza okungekho mpazamo kwedatha edlula kwimodyuli, unikezelo lwamandla kwimodyuli kufuneka luzinzile kwaye lungabina ngxolo.Okubaluleke ngakumbi, umbane oqhuba i-transceiver kufuneka ucocwe ngokufanelekileyo.Izihluzi eziqhelekileyo zichazwe kwiSivumelwano seMithombo emininzi (MSA), ekhokele ukuyilwa koqobo kwezi transceivers.Olunye uyilo olunjalo kwinkcazo ye-SFF-8431 iboniswe ngezantsi.
Iimpawu zamehlo
Ukusebenza kwamehlo kulinganiswa ngempazamo encinci okanye i-BER.Ingxaki ngokuyila i-transceiver optical kukuba iiparamitha ze-optical ze-transmitter kunye ne-receiver kufuneka zilawulwe ukuze nayiphi na i-attenuation enokwenzeka yesignali ye-optical njengoko ihamba phantsi kwefiber ayiphumeleli ekusebenzeni kakubi kwe-BER.Ipharamitha ephambili yomdla yiBER yekhonkco elipheleleyo.Oko kukuthi, indawo yokuqala yekhonkco ngumthombo wesignali yombane eqhuba umthumeli, kwaye ekugqibeleni, umqondiso wombane ufunyenwe ngummkeli kwaye utolikwe ngokujikeleza kwi-host host.Kulezo ziqhagamshelo zonxibelelwano zisebenzisa i-transceivers optical, injongo ephambili kukuqinisekisa ukusebenza kwe-BER kwiindlela ezahlukeneyo zekhonkco kunye nokuqinisekisa ukusebenzisana okubanzi kunye ne-third party transceivers evela kubathengisi abahlukeneyo.
