Kodi Pali Kusiyana kotani pakati pa zingwe za DAC vs AOC?

Direct Gwirizanitsani Chingwe,amatchedwa DAC. Ndi ma transceiver modules otentha otentha monga SFP+, QSFP, ndi QSFP28.

Amapereka njira yotsika mtengo, yotsika kwambiri yolumikizira njira yolumikizirana yothamanga kwambiri kuchokera ku 10G kupita ku 100G kupita ku ma transceivers a fiber optics.

Poyerekeza ndi ma transceivers optics, zingwe zolumikizira mwachindunji zimapereka njira yotsika mtengo yomwe imathandizira ma protocol angapo kuphatikiza 40GbE, 100GbE, Gigabit & 10G Ethernet, 8G FC, FCoE, ndi Infiniband.

Active Optical Cable, yotchedwa AOC.

AOC ndi ma transceivers awiri ophatikizidwa pamodzi ndi chingwe cha fiber, kupanga msonkhano wa gawo limodzi. Monga DAC, Active Optical Cable singasiyanitsidwe.

Komabe, AOC sigwiritsa ntchito zingwe zamkuwa koma zingwe za fiber zomwe zimawalola kuti afike mtunda wautali.

Active Optical Cables amatha kufikira mtunda kuchokera ku 3 metres mpaka 100 metres, koma amagwiritsidwa ntchito mtunda wautali mpaka 30 metres.

Ukadaulo wa AOC wapangidwira ma data angapo, monga 10G SFP +, 25G SFP28, 40G QSFP +, ndi 100G QSFP28.

AOC imakhalanso ngati zingwe zowonongeka, pomwe mbali imodzi ya msonkhano imagawidwa mu zingwe zinayi, iliyonse imathetsedwa ndi transceiver ya chiwerengero chochepa cha deta, zomwe zimalola kugwirizanitsa chiwerengero chachikulu cha madoko ndi zipangizo.

M'ma Data Centers amasiku ano, bandwidth yochulukirapo ikufunika kuti ithandizire kugwiritsa ntchito makina owoneka bwino a seva pomwe makina angapo ophatikizika amaphatikizidwa pa seva imodzi yokhala ndi thupi. Kutengera kuchuluka komwe kukuchulukirachulukira kwa makina ogwiritsira ntchito ndi mapulogalamu omwe akukhala pa seva payekha, virtualization imafuna kufalikira kwa data pakati pa ma seva ndi ma switch. Panthawi imodzimodziyo, kuchuluka ndi mtundu wa zipangizo zomwe zimakhala pa intaneti zawonjezera kwambiri kuchuluka kwa deta yomwe imayenera kutumizidwa ndi kuchoka ku malo osungiramo zinthu (SANs) ndi Network Attached Storage (NAS). Kugwiritsa ntchito kumagwiritsidwa ntchito kwambiri posungira, ma network, ndi misika yama telecom, Ma switch, ma seva, ma router, makhadi olumikizira netiweki (NICs), Host Bus Adapter (HBAs), ndi High Density and High Data Throughput.

KCO Fiber imapereka Chingwe chapamwamba kwambiri cha AOC ndi DAC, chomwe chitha 100% chogwirizana ndi masinthidwe ambiri amtundu monga Cisco, HP, DELL, Finisar, H3C, Arista, Juniper, …
