I-Fiber optic transceivers isetyenziswa ngokubanzi kwindawo yenethiwekhi yangempela apho iintambo ze-Ethernet azikwazi ukugubungela kwaye kufuneka zisebenzise imicu ye-optical ukwandisa umgama wokuhambisa. Ngokuqhelekileyo zibekwe kwindawo yokufikelela kuthungelwano lwemimandla yemetropolitan ebanzi, kwaye zisetyenziswa ngokubanzi kwiiprojekthi ezahlukeneyo zokubeka iliso nokhuseleko. Kodwa ngokuqinisekileyo siya kuhlangabezana neengxaki ezithile kwinkqubo yokusebenzisa i-fiber optic transceivers, ngoko ke siyisombulula njani emva kokujongana nengxaki.
Ukusilela okuqhelekileyo kunye nezisombululo zee-transceivers zefiber optical
1. Luhlobo luni loxhumo olusetyenziswayo xa i-transceiver RJ45 port ixhunyiwe kwezinye izixhobo?
Isizathu: I-RJ45 port ye-transceiver iqhagamshelwe kwikhadi lomnatha we-PC (izixhobo ze-DTE data terminal) usebenzisa i-cross-twisted pair, kunye ne-HUB okanyeTSHINTSHA(Izixhobo zonxibelelwano lwedatha ye-DCE) zisetyenziselwa imigca ehambelanayo.
2. Sisiphi isizathu sokuba ukukhanya kwe-TxLink kucinywe?
Izizathu: a. Qhagamshela isibini esijijekileyo; b. Uqhagamshelwano olubi phakathi kwentloko yekristale ephothiweyo kunye nesixhobo, okanye umgangatho wesibini esijijekileyo ngokwawo; c. Isixhobo asiqhagamshelwanga kakuhle.
3. Sisiphi isizathu sokuba ukukhanya kwe-TxLink kungaqhwanyaza kodwa kuhlale emva kokuba ifayibha idityaniswe ngokufanelekileyo?
Isandi sokuqala: a. Impazamo idla ngokubangelwa ngumgama omde wothumelo; b. Ukuhambelana nekhadi lenethiwekhi (iqhagamshelwe kwiPC).
4. Sisiphi isizathu sokuba ukukhanya kweFxlink kucinywe?
Izizathu: a. Intambo yefiber iqhagamshelwe ngokungalunganga. Indlela yokudibanisa echanekileyo yi-TX-RX, RX-TX okanye imowudi yefiber ayilunganga; b. Umgama wothumelo mde kakhulu okanye ilahleko ephakathi inkulu kakhulu, idlula ilahleko engeyiyo yale mveliso. Isisombululo sithi : Thatha amanyathelo okunciphisa ilahleko ephakathi okanye uyibuyisele ngomgama omde wothumelo; c. Ubushushu obusebenzayo be-optical fiber transceiver buphezulu kakhulu.
5. Sisiphi isizathu sokuba ukukhanya kweFxlink kungabonakali kodwa kuhlale emva kokuba i-fiber ixhunyiwe ngokufanelekileyo?
Unobangela: Esi siphene sibangelwa ngumgama wothumelo ukuba mde kakhulu okanye ilahleko ephakathi inkulu kakhulu, igqitha ilahleko engeyiyo yale mveliso. Isisombululo kukunciphisa ilahleko ephakathi okanye endaweni yayo nge-transceiver yomgama omde wothumelo.
6. Ndingenza ntoni ukuba izibane ezihlanu zilayitiwe zonke okanye isalathisi siqhelekile kodwa asinako ukudluliselwa?
Isizathu: Ngokuqhelekileyo, cima kwaye uqalise kwakhona ukubuyisela okuqhelekileyo.
7. Yintoni iqondo lobushushu le-ambient ye-transceiver?
Unobangela: Imodyuli yefiber optical ichatshazelwa kakhulu bubushushu be-ambient. Nangona inomjikelezo wokuzuza ngokuzenzekelayo, emva kokuba ubushushu budlula uluhlu oluthile, amandla optical emodyuli ye-optical iyachaphazeleka kwaye iyancitshiswa, ngaloo ndlela iyancipha umgangatho wesignali ye-optical network kwaye ibangela ilahleko yepakethe. ikhonkco lokukhanya; (ngokubanzi ubushushu bokusebenza kwemodyuli yefiber ebonakalayo inokufikelela kuma-70 ℃)
8. Ihambelana njani nesivumelwano sesixhobo sangaphandle?
Isizathu: I-10/100M i-fiber transceivers inezithintelo zobude obufanayo njenge-10/100Miiswitshi, ngokuqhelekileyo akukho ngaphezu kwe-1522B okanye i-1536B. Xa itshintshaidityaniswe kwi-ofisi ephakathi ixhasa ezinye iiprothokholi ezikhethekileyo (ezifana neCiss' ISL) Ipakethi engaphezulu iyanda (i-packet ye-Ciss ISL ngaphezulu yi-30Bytes), edlula umda ophezulu wobude besakhelo se-fiber transceiver kwaye ilahlwe yiyo, ebonisa. izinga eliphezulu okanye elingaphumeleliyo lwelahleko yepakethe. Ngeli xesha, i-MTU yesixhobo se-terminal kufuneka ilungiswe Kwiyunithi yokuthumela, i-IP yepakethe ye-IP jikelele i-18 bytes, kunye ne-MTU yi-1500 bytes. Okwangoku, abavelisi bezixhobo zonxibelelwano eziphezulu baneendlela zonxibelelwano zangaphakathi. Ngokuqhelekileyo, indlela yepakethe eyahlukileyo isetyenziselwa ukwandisa ipakethe ye-IP ngaphezulu. Ukuba idatha i-1500 bytes Emva kwepakethe ye-IP, ubungakanani bepakethi ye-IP buya kudlula i-18 kwaye ilahlwe), ukwenzela ukuba ubungakanani bepakethi ehanjiswe kumgca iyanelisayo kumda wesixhobo senethiwekhi kubude besakhelo. I-1522 bytes yeepakethi zongezwa i-VLANtag.
9. Emva kokuba i-chassis isebenze ixesha elithile, kutheni amanye amakhadi esilela ukusebenza kakuhle?
Isizathu: Unikezelo lwamandla lwe-chassis kwangoko lwamkela imowudi yokudlulisa. Ukungonelanga komda wonikezelo lwamandla kunye nelahleko yentambo enkulu zezona ngxaki ziphambili. Emva kokuba i-chassis isebenze ixesha elide, amanye amakhadi akakwazi ukusebenza ngokuqhelekileyo. Xa amanye amakhadi ekhutshiwe, amakhadi aseleyo asebenza ngokwesiqhelo. Emva kokuba i-chassis isebenze ixesha elide, i-oxidation yokudibanisa ibangela ilahleko enkulu yokudibanisa. Olu nikezelo lwamandla luwela ngaphaya kwemimiselo. Uluhlu olufunekayo lunokubangela ukuba ikhadi le-chassis lingaqhelekanga. Amandla aphezulu e-Schottky diode asetyenziselwa ukwahlula kunye nokukhusela amandla e-chassistshintsha, ukuphucula ifom yokudibanisa, kunye nokunciphisa ukuhla kokunikezelwa kwamandla okubangelwa isiphaluka solawulo kunye nekhonkco. Kwangaxeshanye, ukudityaniswa kwamandla ombane kuye kwandiswa, nto leyo eyenza ukuba unikezelo lwamandla olugciniweyo lube lula kwaye lukhuseleke, kwaye luyenza ilunge ngakumbi kwiimfuno zexesha elide elingaphazanyiswanga.
10. Yiyiphi imisebenzi eyenziwa yi-alam yekhonkco kwi-transceiver?
Isizathu: I-transceiver inomsebenzi we-alarm yekhonkco (linkloss). Xa i-fiber inqanyuliwe, iya kuzibuyisela ngokuzenzekelayo kwi-port yombane (oko kukuthi, isalathisi kwi-port yombane nayo iya kuphuma). Ukuba itshintshainolawulo lwenethiwekhi, iya kuboniswa kwitshintshangoko nangoko. Isoftware yolawulo lwenethiwekhi.
