I-100M i-fiber optic transceiver (isibani esisodwa nogesi oyisi-8) Xhuma futhi Udlale kalula

Ukuqonda kanye nomehluko phakathi kokuhlukaniswa okunengqondo kanye nokuzihlukanisa ngokomzimba mayelana nama-transceivers e-Ethernet fiber optic

Namuhla, ngokusetshenziswa okubanzi kwe-Ethernet, emikhakheni eminingi, njengamandla kagesi, amabhange, ukuphepha komphakathi, amasosha, ujantshi wesitimela, kanye namanethiwekhi angasese amabhizinisi amakhulu nezikhungo, kunezidingo ezibanzi zokuzihlukanisa ngokomzimba kwe-Ethernet, kepha yini ukuhlukaniswa ngokomzimba I-Ethernet?Kuthiwani ngenetha?Iyini i-Ethernet ehlukanisiwe ngokunengqondo?Sikwahlulela kanjani ukuzihlukanisa okunengqondo kanye nokuzihlukanisa ngokomzimba?
Kuyini ukuzihlukanisa ngokomzimba:
Lokhu okubizwa ngokuthi "ukuhlukaniswa ngokomzimba" kusho ukuthi akukho ukuxhumana kwedatha phakathi kwamanethiwekhi amabili noma ngaphezulu, futhi akukho ukuxhumana kungqimba olubonakalayo/isendlalelo sesixhumanisi sedatha/sendlalelo se-IP.Inhloso yokuhlukaniswa ngokomzimba ukuvikela amabhizinisi wehadiwe kanye nezixhumanisi zokuxhumana zenethiwekhi ngayinye ezinhlekeleleni zemvelo, ukucekelwa phansi kwabantu kanye nokuhlaselwa kwe-wiretapping.Isibonelo, ukuhlukaniswa ngokomzimba kwenethiwekhi yangaphakathi kanye nenethiwekhi yomphakathi kungaqinisekisa ngempela ukuthi inethiwekhi yolwazi lwangaphakathi ayihlaselwa izigebengu ze-inthanethi.

Kuyini ukuzihlukanisa okunengqondo:
I-isolator enengqondo iphinde ibe ingxenye yokuhlukanisa phakathi kwamanethiwekhi ahlukene.Kusese nokuxhunywa kwesiteshi sedatha kungqimba olubonakalayo/isixhumanisi sedatha ekugcineni okungazodwa, kodwa izindlela zobuchwepheshe zisetshenziswa ukuze kuqinisekiswe ukuthi awekho amashaneli edatha ezindaweni ezingazodwa, okungukuthi, ngokunengqondo.Ukuzihlukanisa, ukuhlukaniswa okunengqondo kwama-transceivers optical network emakethe ngokuvamile kufinyelelwa ngokuhlukanisa amaqembu e-VLAN (IEEE802.1Q);

I-VLAN ilingana nesizinda sokusakaza sesendlalelo sesibili (usendlalelo sesixhumanisi sedatha) semodeli yereferensi ye-OSI, engalawula isiphepho sokusakaza ngaphakathi kwe-VLAN.Ngemva kokuhlukanisa i-VLAN, ngenxa yokwehliswa kwesizinda sokusakaza, ukuhlukaniswa kwezimbobo zenethiwekhi yeqembu le-VLAN ehlukene kuyabonakala..

Okulandelayo umdwebo wohlelo lokuhlukaniswa okunengqondo:

Lesi sithombe esingenhla siwumdwebo womdwebo we-1 optical 4 kagesi optic optic transceiver ehlukanisiwe ngokunengqondo: Iziteshi ze-Ethernet ezi-4 (100M noma i-Gigabit) zifana nemizila engu-4 yomgwaqo omkhulu, engena emhubheni, umhubhe umzila owodwa, futhi Bese kuba nemizila engu-4, 1 optical kanye 4 kagesi 100M logic isolation fibre optic transceivers, port optical futhi 100M, futhi umkhawulokudonsa 100M, ngakho idatha yenethiwekhi evela 4 amashaneli 100M kufanele ihlelwe 100M. ishaneli yefiber.Uma ungena futhi uphuma, shaya umugqa bese uphumela emigwaqweni ehambisana nawo;ngakho-ke, kulesi sixazululo, idatha yenethiwekhi ixubene ku-Fiber Channel futhi ayihlukanisiwe nhlobo;
