Ukusebenza kwamanje kwenethiwekhi ye-DCI (Ingxenye Yokuqala)
Ngemuva kokuthi inethiwekhi ye-DCI yethule ubuchwepheshe be-OTN, kulingana nokwengeza lonke ucezu lomsebenzi owawungekho ngaphambilini mayelana nokusebenza.Inethiwekhi yesikhungo sedatha evamile iyinethiwekhi ye-IP, eyingxenye yobuchwepheshe benethiwekhi obunengqondo.I-OTN ku-DCI iwubuchwepheshe bongqimba obubonakalayo, ...Funda kabanzi -
Yini i-DCI Box
Umsuka wenethiwekhi ye-DCI Ekuqaleni, isikhungo sedatha sasilula, sinamakhabhinethi ambalwa + ama-air conditioner ambalwa aphezulu ekamelweni elingahleliwe, bese kuba amandla omuzi avamile + ama-UPS ambalwa, futhi yaba isikhungo sedatha. .Nokho, lolu hlobo lwesikhungo sedatha luncane ngesilinganiso futhi luphansi ngokwethembeka...Funda kabanzi -
Inzuzo ye-WIFI 6 ONT
Uma kuqhathaniswa nezizukulwane zangaphambili zobuchwepheshe be-WiFi, izici eziyinhloko zesizukulwane esisha se-WiFi 6 yilezi: Uma kuqhathaniswa nesizukulwane sangaphambilini se-802.11ac WiFi 5, izinga eliphezulu lokudlulisela i-WiFi 6 linyusiwe lisuka ku-3.5Gbps yangaphambili laya ku-9.6Gbps. , futhi isivinini setiyori sine...Funda kabanzi -
we-QSFP28 optical modules akhona?
I-QSFP28 optical module ingashiwo ukuthi iyisizukulwane esisha semojula ye-optical, ethandwa abakhiqizi abaningi ngenxa yezinzuzo zayo ezifana nobukhulu obuncane, ukuminyana kwechweba eliphezulu, nokusetshenziswa kwamandla okuphansi.Ngakho-ke, yiziphi izinhlobo zamamojula we-QSFP8 optical akhona?I-QSFP28 optical module yaziwa nangokuthi...Funda kabanzi -
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 -
