I-Fiber optic transceiver yiyunithi yokuguqula imidiya ye-Ethernet etshintshisa umgama omfutshane ojijekileyo wemiqondiso yombane kunye nemiqondiso yokubona ekude.Ikwabizwa ngokuba yi-photoelectric converter (iFiber Converter) kwiindawo ezininzi.
1. Ukukhanya kwekhonkco akukhanyi
(1) Khangela ukuba umgca wefiber optical uvuliwe;
(2) Khangela ukuba ilahleko yomgca we-fiber optical inkulu kakhulu, edlula uluhlu lokufumana izixhobo;
(3) Khangela ukuba i-fiber optical interface ixhunyiwe ngokuchanekileyo, i-TX yendawo ixhunyiwe kwi-RX ekude, kwaye i-TX ekude ixhunyiwe kwi-RX yendawo.(d) Jonga ukuba isinxibelelanisi sosinga olubonakalayo sifakwe ngokufanelekileyo kujongano lwesixhobo, ingaba udidi lokutsiba luyahambelana nojongano lwesixhobo, ingaba udidi lwesixhobo luyahambelana nosinga olubonakalayo, nokuba ubude bothumelo besixhobo buhambelana nomgama.
2. Isibane soqhagamshelwano lwesekethe asikhanyisi
(1) Khangela ukuba intambo yenethiwekhi ivuliwe kusini na;
(2) Khangela ukuba uhlobo loqhagamshelwano luyahambelana na: amakhadi enethiwekhi kunye neerotha kunye nezinye izixhobo zisebenzisa iintambo ezinqamlezileyo, kwaye iiswitshi, ii-hubs kunye nezinye izixhobo zisebenzisa iintambo ezithe ngqo;
(3) Jonga ukuba isantya sothumelo lwesixhobo siyahambelana na.
3. Ilahleko enkulu yepakethe yenethiwekhi
(1) Izibuko lombane le-transceiver kunye nojongano lwesixhobo senethiwekhi, okanye imowudi ephindwe kabini yojongano lwesixhobo kuzo zombini iziphelo azihambelani;
(2) Kukho ingxaki ngentambo ephothiweyo kunye nentloko ye-RJ-45, ngoko jonga;
(3) Ingxaki yoxhulumaniso lweFayibha, nokuba i-jumper ihambelana nojongano lwesixhobo, nokuba i-pigtail ihambelana ne-jumper kunye nohlobo lwe-coupler, njl.;
(4) Ingaba ilahleko yomgca we-fiber optical idlula ukuqonda kokufumana isixhobo.
4. Emva kokuba i-fiber optic transceiver ixhunyiwe, iziphelo ezimbini azikwazi ukunxibelelana
(1) Uxhulumaniso lwefiber luguqulwa, kwaye i-fiber exhunywe kwi-TX kunye ne-RX iyatshintshwa;
(2) I-interface ye-RJ45 kunye nesixhobo sangaphandle asixhunyiwe ngokuchanekileyo (nikela ingqalelo kwi-straight-through and splicing).Ujongano lwefiber optical (i-ceramic ferrule) ayihambelani.Eli phutha libonakaliswa ngokukodwa kwi-transceiver ye-100M kunye nomsebenzi wokulawula i-photoelectric mutual mutual, njenge-APC ferrule.I-pigtail eqhagamshelwe kwi-transceiver ye-PC ferrule ayiyi kunxibelelana ngokuqhelekileyo, kodwa ayiyi kuchaphazela i-transceiver yokulawula i-non-optical mutual control.
5. Vula kwaye ucime isenzeko
(1).Kusenokwenzeka ukuba indlela yokubona indlela yokubona inkulu kakhulu.Ngeli xesha, imitha yamandla optical ingasetyenziselwa ukulinganisa amandla optical ekupheleni kokufumana.Ukuba ikufuphi noluhlu olufumanayo lwe-sensitivity, inokugwetywa ngokusisiseko njengokungaphumeleli kwendlela ye-optical phakathi koluhlu lwe-1-2dB;
(2).Kungenzeka ukuba utshintsho oluqhagamshelwe kwi-transceiver luyimpazamo.Ngeli xesha, buyisela utshintsho ngePC, oko kukuthi, ii-transceivers ezimbini zixhunywe ngokuthe ngqo kwi-PC, kwaye zombini iziphelo ziyi-PING.Ukuba ayibonakali, inokugwetywa ngokusisiseko njengokutshintsha.impazamo;
(3).I-transceiver inokuba nempazamo.Ngeli xesha, unokudibanisa zombini iziphelo ze-transceiver kwi-PC (ungadluli kwi-switch).Emva kokuba zombini iziphelo zingenayo ingxaki nge-PING, dlulisela ifayile enkulu (100M) okanye ngaphezulu ukusuka kwelinye icala ukuya kwelinye, kwaye ugcine isantya salo, ukuba isantya sicotha kakhulu (iifayile ezingaphantsi kwe-200M zinokugqithiselwa ngaphezu kwemizuzu eyi-15), inokugwetywa ngokusisiseko njengokusilela kwe-transceiver
6. Emva kokuba umatshini uphazamisekile kwaye uqalise kwakhona, ubuyela kwisiqhelo
Le nto ibangelwa ngokubanzi kukutshintsha.Ukutshintsha kuya kwenza ubhaqo lwempazamo ye-CRC kunye nokuqinisekisa ubude kuyo yonke idatha efunyenweyo.Ukuba impazamo ifunyenwe, ipakethi iya kulahlwa, kwaye ipakethi echanekileyo iya kuthunyelwa.
Nangona kunjalo, ezinye iipakethi ezineempazamo kule nkqubo azinakufunyanwa kwi-CRC yokukhangela impazamo kunye nokujonga ubude.Iipakethi ezinjalo aziyi kuthunyelwa ngaphandle okanye zilahlwe ngexesha lenkqubo yokuthunyelwa.Ziya kuqokelelana kwisithinteli esiguqukayo.(Buffer), ayinakuze ithunyelwe ngaphandle.Xa isithinteli sigcwele, siya kubangela ukuba iswitshi iphazamiseke.Ngenxa yokuba ngeli xesha ukuqalisa kwakhona i-transceiver okanye ukuqala kwakhona ukutshintshela kunokubuyisela unxibelelwano kwisiqhelo.
