Izimo zohlelo lokusebenza lwe-OTN
I-OTN ne-PTN Kufanele kushiwo ukuthi i-OTN ne-PTN ubuchwepheshe obubili obuhluke ngokuphelele, futhi uma sikhuluma ngobuchwepheshe, kufanele kushiwo ukuthi akukho ukuxhumana.I-OTN inethiwekhi yezokuthutha ebonakalayo, ethuthukiswe kusukela kubuchwepheshe bendabuko bokuhlukaniswa kwe-wavelength.Ingeza ngokuyinhloko i-intellig...Funda kabanzi -
I-OTN (Optical Transport Network) iyinethiwekhi yokudlulisa ehlela amanethiwekhi kungqimba yokubona ngokusekelwe kubuchwepheshe bokuphindaphinda kwe-wavelength division.
Iwumgogodla wenethiwekhi yesizukulwane esilandelayo.Kalula nje, iyinethiwekhi yezokuthutha yesizukulwane esilandelayo esekwe yiwavelength.I-OTN inethiwekhi yezokuthutha esekelwe kubuchwepheshe be-wavelength division multiplexing ehlela inethiwekhi kungqimba olubonakalayo, futhi iwumgogodla wezokuthutha ne...Funda kabanzi -
Umehluko phakathi kwe-DWDM ne-OTN
I-DWDM ne-OTN yizinhlelo ezimbili zobuchwepheshe ezakhiwe ubuchwepheshe bokudlulisa i-wavelength division transmission eminyakeni yamuva: I-DWDM ingathathwa njenge-PDH yangaphambilini (i-point-to-point transmission), futhi izinsizakalo ze-inthanethi nezingaxhunyiwe ku-inthanethi ziqedwa ku-ODF ngokusebenzisa ama-hard jumpers;I-OTN ifana ne-SDH (izinhlobo ezehlukene ze...Funda kabanzi -
Ukuhlukaniswa kwekhebula elisheshayo le-DAC elivamile
Ikhebula lejubane eliphezulu le-DAC (Ikhebula lokunamathisela okuqondile) ngokuvamile lihunyushwa njengekhebula eliqondile, ikhebula le-copper lokuxhuma ngokuqondile noma ikhebula elinesivinini esikhulu.Ichazwa njengesikimu soxhumano lwebanga elifushane esibiza kancane esithatha indawo yamamojula abonakalayo.Zombili iziphetho zekhebula elinesivinini esikhulu zinamamojula Ahlanganisa amakhebula, angaphindi...Funda kabanzi -
Ukuhlaziywa okujulile kwama-fiber optic transceivers
Ngenxa yomkhawulokudonsa ophezulu kanye nokunciphisa kancane okulethwa i-fiber optical, isivinini senethiwekhi sithatha isivinini esikhulu.Ubuchwepheshe be-Fiber optic transceiver nabo buvela ngokushesha ukuze buhlangabezane nezidingo ezihlala zikhula zejubane namandla.Ake sibheke ukuthi le ntuthuko izobathinta kanjani ...Funda kabanzi -
Uyini umehluko phakathi kwe-fiber optic transceivers kanye nama-transceivers e-Ethernet?
Ama-transceivers e-FC (Fibre Channel) ayingxenye ebalulekile yengqalasizinda ye-Fiber Channel, futhi ama-transceivers e-Ethernet ahlanganiswe nokushintsha kwe-Ethernet ayinhlanganisela ethandwayo efanayo lapho kuthunyelwa i-Ethernet.Ngokusobala, lezi zinhlobo ezimbili zama-transceivers zisebenzisa izinhlelo zokusebenza ezahlukene, kodwa yini ngempela...Funda kabanzi -
Umehluko phakathi kokushintshwa kwe-fiber optic nama-fiber optic transceivers!
Ama-transceiver abonakalayo namaswishi abalulekile ekudluliselweni kwe-Ethernet, kodwa ayahluka ekusebenzeni nasekusetshenzisweni.Ngakho-ke, yini umehluko phakathi kwe-fiber optic transceivers namaswishi?Uyini umehluko phakathi kwe-fiber optic transceivers namaswishi?I-Optical fiber transceiver iyinhlangano...Funda kabanzi -
Ungawahlola kanjani ama-fiber optic transceivers?
Ngokuthuthukiswa kwenethiwekhi kanye nokuthuthuka kobuchwepheshe, abakhiqizi abaningi bezingxenye ze-fiber optic baye bavela emakethe, bezama ukubamba ingxenye yomhlaba wenethiwekhi.Njengoba laba bakhiqizi bekhiqiza izakhi ezahlukahlukene, inhloso yabo ukwenza ikhwalithi ephezulu futhi ihlanganiswe ...Funda kabanzi -
Izinsiza ezisekelayo ze-fiber optic transceivers: I-Optical Distribution Frame (ODF) Basics
Ukusatshalaliswa kwe-fiber optics bekulokhu kukhula, kuqhutshwa isidingo samazinga edatha anesivinini esikhulu.Njengoba i-fiber efakiwe ikhula, ukuphathwa kwamanethiwekhi okuthutha okubonakalayo kuba nzima kakhulu.Kunezici eziningi okufanele zicatshangelwe ngesikhathi se-fiber cabling, njengokuguquguquka, ukuba nokwenzeka kwesikhathi esizayo, ukuthunyelwa...Funda kabanzi -
Umehluko phakathi kwe-single-mode kanye ne-multi-mode fibre optic transceivers Izindlela ezi-3 zokuhlukanisa i-single-mode kanye ne-multi-mode fibre optic transceivers
1. Umehluko phakathi kwe-single-mode kanye ne-multi-mode fibre optic transceivers Ububanzi bomnyombo we-multimode fiber ngu-50 ~ 62.5μm, ububanzi obungaphandle be-cladding yi-125μm, kanti ububanzi obuyinhloko be-fiber yemodi eyodwa yi-8.3μm , futhi ububanzi bangaphandle be-cladding buyi-125μm.Umsebenzi w...Funda kabanzi -
