Ukulungisa kunokubiza kakhulu nge-SFP, njengoko iintambo zefayibha kunye neemodyuli zifuna unyango oluthambileyo ngakumbi.

• Indlela yoPhuculo: I-SFP iyakhanya ukuze kukhuselwe kwixesha elizayo. Njengoko isantya senethiwekhi sisanda—masithi, i-25G okanye i-100G—i-SFP inokutshintsha iimodyuli endaweni yeswitshi yonke. I-RJ45 ithatha indawo ethe kratya. Wakuba ufikelele kumda weemitha ezili-100 okanye ufuna isantya esingaphezulu, kuya kufuneka uphucule kakhulu.

• Uxinano kunye noKhula koTshintsho: Iiports ze-SFP zincinci, ngoko ke ungazifaka ezininzi kwiswitshi. Oku kubalulekile kwiinethiwekhi ezixineneyo kwiindawo zolwazi okanye kwiikhampasi ezinkulu, okukuvumela ukuba uyile ulwandiso ngaphandle kokuphucula izixhobo eziphambili.

• Iindleko Zexesha Elide: Nangona i-RJ45 ingabizi kakhulu ekuqaleni, isenokungahlangabezani neemfuno zesantya okanye zoluhlu olukhulayo. Ukuguquguquka kwe-SFP kunokuguqulela ekongeni iindleko ngokuhamba kwexesha, kunye nokuphuculwa okwenziwe lula kwaye kulungele ngcono ubuchwepheshe bexesha elizayo.

Iindlela zothungelwano zibonisa isidingo esongezelelekileyo sesantya, ubuchule kunye noqwalaselo oluxineneyo. Iimodyuli ze-SFP, ngenxa yokuziqhelanisa kwazo, zixhotyiswe kakuhle kolu tshintsho. Ii-OLT SFPs (kwiinethiwekhi zokufikelela kwifayibha) nazo zibonisa utshintsho oluya kwifayibha yomqolo kunye nokufikelela kuzo zombini, njengoko ifayibha iqhubeka isasazeka kwihlabathi liphela.

Uhlahlo-lwabiwo mali alupheleli nje kwinto oyichithayo ngoku. Kububulumko ukuqwalasela iindleko zokuseta kunye neendleko zokuphucula kwixesha elizayo. Isiqhagamsheli osikhethayo namhlanje siya kuba nefuthe kwindlela esilawuleka ngayo—nesingabiza ngayo—ukuze sandise okanye siphucule inethiwekhi yakho kwixesha elizayo.

Ukuchonga Iingxaki Eziqhelekileyo

Ukulungisa iingxaki zeeports ze-SFP, kuquka iimodyuli ze-RJ45 copper SFP kunye nee-transceivers ze-OLT SFP, kubalulekile ekugcineni ukuqina kwenethiwekhi. Ngayinye inemiba yayo eyahlukileyo, kwaye ukuqonda umahluko kunceda ukugcina izixhobo zakho zenethiwekhi zisebenza kakuhle, nokuba inethiwekhi yakho incinci okanye inkulu ngobukhulu.

Ukusilela kweKhonkco ye-SFP

Iimodyuli ze-SFP zihlala zidibana neengxaki xa kukho ukungangqinelani kwesantya/uhlobo phakathi kwe-SFP kunye nesixhobo. Ukuba isixhobo asixhasi isantya semodyuli ye-SFP—umzekelo, ukusebenzisa i-SFP ye-10 Gbps kwizibuko le-1 Gbps—ikhonkco lisenokungaqini konke konke. Ungalibali ukuqinisekisa ukuba iinkcukacha zesixhobo sakho zivumela iimodyuli ezintsha ngaphambi kokuba uzifake!

Ukulahleka kwesignali yenye imbangela enkulu yokusilela kwe-SFP. Xa i-fiber ibaleka ixesha elide, ingakumbi ezo zingaphezulu kweekhilomitha ezili-10, i-signal inokulahleka okanye yonakale. Ukuba usebenzisa izixhobo zokubeka esweni, ungayibona kwangethuba le nto—jonga ukuba ayisebenzi kakuhle na, iipakethi eziwileyo, okanye i-signal ebuthathaka. Ukucoca izihlanganisi ze-fiber nokuhlola umonakalo womzimba kuyanceda kakhulu.

Ukuhambelana nako kubalulekile. Ezinye iimpawu zithatha ii-SFP zazo kuphela. Ukuba uxuba 'n' match, amakhonkco asenokungasebenzi. Ukuhlolwa rhoqo—njengokuhlela zonke izixhobo zekhompyutha kunye nokuvavanya uqhagamshelo—kufumanisa ezi ngxaki ngaphambi kokuba zikhule.

Iimpazamo zoQhagamshelo lwe-RJ45

Iingxaki ze-RJ45 copper SFPs zibonakala njengokuhla okungaqhelekanga okanye isantya esicothayo. Eyona nto irhanelekayo kukuba intambo embi okanye uqhagamshelo olukhululekileyo lukhona. Kuba iintambo zecopper zilungele kuphela ukuya kwiimitha ezili-100, ukugqitha apho kunokunciphisa isantya ngokukhawuleza okanye kubulale ikhonkco. Hlaziya iintambo kwaye uvavanye ngokuhamba okufutshane.

Oko kuthethiweyo, qinisekisa ukuba ii-ports zakho ze-RJ45 nazo zicwangciswe ngokuchanekileyo. Useto olungalunganga—njenge-duplex engahambelaniyo okanye isantya—lukhokelela kwiimpazamo. Kufanelekile ukuqinisekisa ezi kwiswitshi yakho okanye kulungiselelo lwe-router. Ukujonga ukusebenza kwenethiwekhi ngezixhobo zokubeka esweni ezisisiseko kunokunceda ekuchongeni iingxaki ezincinci ngaphambi kokuba ziqhubeke zingasebenzi.

Iingxaki ze-OLT SFP

Iimodyuli ze-OLT SFP, ezisetyenziswa kwiinethiwekhi zefayibha, ngamanye amaxesha zidibana neengxaki ezifana nonxibelelwano olubi okanye isantya esicothayo. Ezi ngxaki zihlala ziphelela kwiziphelo zefayibha ezingcolileyo okanye i-firmware endala. Ukucoca i-connector okanye uhlaziyo lwe-firmware ludla ngokwenza izinto zibe ngcono ngokukhawuleza.

I-Firmware yenza umahluko omkhulu ekusebenzeni kwe-OLT SFP. Ukugcina i-OLT SFP isebenza kunceda ekuphepheni iingxaki nasekuzinzeni. Ukuhlolwa rhoqo kweentambo kunye noqhagamshelo kunceda ekubambeni iingxaki kwangethuba ngaphambi kokuba abasebenzisi babone ukonakala kwenkonzo.

Isiphelo

Ukukhetha icandelo elifanelekileyo lenethiwekhi kunefuthe ekusebenzeni. I-SFP yenza ii-fiber kunye nee-copper links zitshintshelane. I-RJ45 copper SFP inamathela kwiintambo eziqhelekileyo kwaye ifake kwiindlela ezininzi zokucwangcisa. I-OLT SFP iqhagamshela kwi-fiber kwiinethiwekhi ezinkulu ezifana ne-intanethi yesixeko sonke. Nganye inenjongo yayo—cinga ngesantya, ixabiso, kunye nezixhobo zakho ezikhoyo. Isikolo eNairobi sikhethe i-RJ45 copper SFP ukusebenzisa iintambo ezindala kwaye songe iindleko, ngelixa isixeko saseBrazil sisebenzise i-OLT SFP kwi-fiber ekhawulezayo emakhaya. Izigqibo ezincinci zenza impembelelo enkulu kwindlela esiqhagamshela ngayo. Ngaba uyilo lwenethiwekhi olucingayo okanye ibali olibalisayo? Shiya uluvo lwakho okanye umbuzo apha ngezantsi. Masishiye incoko ivulekile.

Imibuzo ebuzwa qho

Yintoni umahluko omkhulu phakathi kwe-SFP, i-RJ45 copper SFP, kunye ne-OLT SFP?

I-SFP, imodyuli ebalulekileyo ye-transceiver kwiinethiwekhi zefayibha kunye ne-copper, ibandakanya i-RJ45 copper SFP edibanisa neentambo ze-copper Ethernet, ngelixa i-OLT SFP isetyenziswa rhoqo kwiindawo ze-FTTH ukuze kudluliselwe idatha ngokufanelekileyo.

Ndingayisebenzisa i-RJ45 copper SFP nakweyiphi na indawo ye-SFP?

Uninzi lweeport ze-SFP zamkela iimodyuli ze-RJ45 ze-copper SFP, kodwa kubalulekile ukuqinisekisa ukuhambelana kwesixhobo ukuze kukhethwe izixhobo zenethiwekhi.

Ndingayikhetha nini i-OLT SFP kunezinye iintlobo?

Iimodyuli ze-OLT SFP ze-fiber optic kumboneleli weenkonzo okanye kwiimeko ze-FTTH zivumela amakhonkco omgama omde, ahamba ngesantya esiphezulu phakathi kwesiphelo sendlela yokukhanya kunye nezixhobo zababhalisileyo, nto leyo ephucula ukuseta inethiwekhi.

Ngaba zonke iimodyuli ze-SFP ziyatshintshana?

Ayizizo zonke ii-SFP, kuquka iimodyuli ze-copper SFP kunye nee-transceivers ze-fiber SFP, ezenziwe ngokulinganayo. Ukuhambelana kwemodyuli kuxhomekeke kwisixhobo, uhlobo lwenethiwekhi, kunye nesantya esifunekayo.

Zithini iingenelo zokusebenzisa iimodyuli ze-SFP?

Iimodyuli ze-SFP zibonelela ngokuguquguquka, ukuphuculwa okulula, kunye nenkxaso kwiintambo ezahlukeneyo kunye nesantya, kubandakanya iimodyuli ze-SFP zobhedu kunye neemodyuli ze-SFP zefayibha. Zikunceda ekuhlengahlengiseni useto lwenethiwekhi ngokweemfuno eziguqukayo, ngaphandle kokutshintsha isixhobo sonke.

Ndingazigcina njani kwaye ndizifake njani iimodyuli ze-SFP?

Faka iimodyuli ze-SFP zobhedu ngokuzityhala ngononophelo kwii-port ze-SFP. Coca izihlanganisi phambi kokuba uzifake kwaye ungazichukumisi iziphelo zefayibha, njengoko uthuli kunye nezihlanganisi ezikhululekileyo zibulala ukusebenza.

Ngaba kukho umahluko omkhulu weendleko phakathi kweentlobo ze-SFP?

Ewe, ixabiso liyahluka ngohlobo kunye nokusetyenziswa. Iimodyuli ze-RJ45 copper SFP zihlala zibiza kancinci kunee-fiber SFP, nto leyo eyenza zibe lukhetho olukhethwayo kwiisetingi ezininzi zenethiwekhi. Ii-OLT SFP, ezisetyenziswa kwiindawo ezithile, zibiza kakhulu xa kujongwa iseti yazo yeempawu.
