I-100M i-fiber optic transceiver (ukukhanya okunye kunye nombane we-8) Iplagi kunye nokuDlala ngokulula ukuSebenzisa

Ukuqonda kunye nomahluko phakathi kokuhlukaniswa okunengqiqo kunye nokuhlukaniswa ngokomzimba malunga ne-Ethernet fiber optic transceivers

Kule mihla, ngokusetyenziswa okubanzi kwe-Ethernet, kwimimandla emininzi, njengamandla ombane, ibhanki, ukhuseleko loluntu, umkhosi, umzila kaloliwe, kunye nothungelwano lwabucala lwamashishini amakhulu kunye namaziko, kukho iimfuno ezibanzi zokufikelela kwi-Ethernet, kodwa yintoni ukuhlukaniswa ngokwasemzimbeni. Ethernet?Kuthekani ngomnatha?Yintoni i-Ethernet eyodwa ngokwengqiqo?Sikugweba njani ukuba wedwa okusengqiqweni ngokuchasene nokuba wedwa ngokwasemzimbeni?
Yintoni ukuzahlula ngokwasemzimbeni:
Into ebizwa ngokuba "yi-physical isolation" ithetha ukuba akukho ukusebenzisana kwedatha phakathi kweenethiwekhi ezimbini okanye ngaphezulu, kwaye akukho qhagamshelwano kuluhlu lomzimba / ikhonkco yedatha / umaleko we-IP.Injongo yokwahlukaniswa ngokomzimba kukukhusela amaziko e-hardware kunye namakhonkco onxibelelwano womnatha ngamnye kwiintlekele zendalo, i-sabotage eyenziwe ngabantu kunye nokuhlaselwa kwe-wiretapping.Umzekelo, ukwahlukaniswa ngokomzimba kwenethiwekhi yangaphakathi kunye nenethiwekhi yoluntu inokuqinisekisa ngokwenene ukuba inethiwekhi yolwazi lwangaphakathi ayihlaselwa ngabaduni abavela kwi-Intanethi.

Yintoni ukubekwa wedwa okusengqiqweni:
I-isolator enengqondo ikwalicandelo lokuzahlula phakathi kwenethiwekhi ezahlukeneyo.Kusekho uxhulumaniso lweshaneli yedatha kwinqanaba lomzimba / ikhonkco yedatha kwiiphelo ezizimeleyo, kodwa iindlela zobugcisa zisetyenziselwa ukuqinisekisa ukuba akukho ziteshi zedatha kwiiphelo ezizimeleyo, oko kukuthi, ngokwengqiqo.Ukuzihlukanisa, ukuhlukaniswa okunengqiqo kwe-network optical transceivers / switches kwimarike ngokuqhelekileyo kufezekiswa ngokwahlula amaqela eVLAN (IEEE802.1Q);

I-VLAN ilingana ne-domain yokusasazwa kwinqanaba lesibini (idatha yekhonkco yedatha) yemodeli yereferensi ye-OSI, enokulawula isaqhwithi sosasazo ngaphakathi kweVLAN.Emva kokwahlula i-VLAN, ngenxa yokunciphisa indawo yosasazo, ukwahlukaniswa kwamazibuko amabini ahlukeneyo enethiwekhi ye-VLAN ayenzeka..

Oku kulandelayo ngumzobo weskim wokwahlula okusengqiqweni:

Lo mfanekiso ungasentla ngumzobo weskimu somzobo we-1 optical 4 we-fiber optic transceiver yombane: I-4 iziteshi ze-Ethernet (100M okanye i-Gigabit) zifana neendlela ezi-4 zohola wendlela, zingena kwitonela, itonela yindlela enye, kwaye Emva koko kukho imizila ye-4, i-1 optical kunye ne-4 yombane i-100M logic isolation fiber optic transceivers, i-port optical iphinde ibe yi-100M, kwaye i-bandwidth yi-100M, ngoko ke idatha yenethiwekhi evela kwi-4 iziteshi ze-100M kufuneka ihlelwe kwi-100M. umjelo wefiber.Xa ungena kwaye uphuma, dwelisa kwaye uphume kwiindlela zabo ezihambelanayo;ngoko ke, kwesi sisombululo, idatha yenethiwekhi ixutywe kwiFiber Channel kwaye ayihlukani kwaphela;
