Yimuphi umehluko phakathi kwezintambo ze-DAC ne-AOC?

Ikhebula Lokunamathisela Ngokuqondile,okubizwa ngokuthi i-DAC. Ngamamojula e-transceiver angashintshaniswayo njenge-SFP+, QSFP, kanye ne-QSFP28.

Ihlinzeka ngesisombululo se-interconnects esingabizi kakhulu nesinobuningi obukhulu se-interconnects esheshayo kusukela ku-10G kuya ku-100G kuya kuma-transceivers e-fiber optic.

Uma kuqhathaniswa nama-transceivers e-optics, amakhebula anamathisela ngqo ahlinzeka ngesisombululo esingabizi kakhulu esisekela amaphrothokholi amaningi afaka phakathi i-40GbE, i-100GbE, i-Gigabit kanye ne-10G Ethernet, i-8G FC, i-FCoE, kanye ne-Infiniband.

Ikhebula Elibonakalayo Elisebenzayo, okubizwa ngokuthi i-AOC.

I-AOC iyi-transceivers ezimbili ezixhunywe ndawonye ngekhebula le-fiber, okudala ukuhlanganiswa okuyingxenye eyodwa. Njenge-DAC, ikhebula le-Active Optical alikwazi ukuhlukaniswa.

Kodwa-ke, i-AOC ayisebenzisi izintambo zethusi kodwa izintambo zefayibha ezibavumela ukuthi bafinyelele amabanga amade.

Amakhebula E-Active Optical angafinyelela amabanga ukusuka kumamitha amathathu kuya kwayi-100, kodwa avame ukusetshenziswa ebangeni elingafika kumamitha angu-30.

Ubuchwepheshe be-AOC buthuthukiswe ngamanani amaningana edatha, njenge-10G SFP+, 25G SFP28, 40G QSFP+, kanye ne-100G QSFP28.

I-AOC ikhona futhi njengezintambo eziphumayo, lapho uhlangothi olulodwa lwenhlangano luhlukaniswe khona izintambo ezine, ngayinye iqedwa yi-transceiver enesilinganiso esincane sedatha, okuvumela ukuxhuma inani elikhulu lamachweba namadivayisi.

Kuma-Data Center anamuhla, kudingeka i-bandwidth eyengeziwe ukusekela ukusetshenziswa kwe-server virtualization lapho imishini eminingi ebonakalayo ihlanganiswa khona kuseva eyodwa yokusingatha ebonakalayo. Ukuze kuhlangatshezwane nenani elikhulayo lezinhlelo zokusebenza nezinhlelo zokusebenza ezihlala kumaseva ngamanye, i-virtualization idinga ukudluliselwa kwedatha okwandisiwe kakhulu phakathi kwamaseva namaswishi. Ngesikhathi esifanayo, inani kanye nohlobo lwamadivayisi ahlala kunethiwekhi kukhulise kakhulu inani ledatha okudingeka idluliselwe kumanethiwekhi endawo yokugcina (ama-SAN) kanye ne-Network Attached Storage (ama-NAS). Uhlelo lokusebenza lusetshenziswa kakhulu kuzinhlelo zokusebenza ze-I/O ezisheshayo ezimakethe zokugcina, zokuxhumana, kanye nezokuxhumana, ama-Switch, amaseva, ama-router, amakhadi esixhumi senethiwekhi (ama-NIC), ama-Host Bus Adapter (ama-HBA), kanye ne-High Density kanye ne-High Data Throughput.

I-KCO Fiber inikeza ikhebula le-AOC ne-DAC elisezingeni eliphezulu, elingahambisana ngo-100% nezinhlobo eziningi zokushintshana kwemikhiqizo njengeCisco, HP, DELL, Finisar, H3C, Arista, Juniper, … Sicela uxhumane nethimba lethu lokuthengisa ukuze uthole ukwesekwa okungcono kakhulu mayelana nenkinga yobuchwepheshe kanye nentengo.
