DAC
Direct Cable (DAC) yog Direct Cable lossis tooj liab Cable. Nws hais txog kev txhim kho lub teeb modules ntawm ob qho kawg ntawm kev kub ceev jumper. Los ntawm kev txuas mus rau router lossis server, nws tau siv dav hauv thaj chaw cia khoom network, chaw khaws ntaub ntawv thiab kev sib txuas hauv computer ua haujlwm siab, uas tau nce zuj zus hauv kev sib txuas lus hauv network.
Qhov zoo ntawm high-speed cable DAC yog raws li nram no:
1. Kev ua haujlwm siab: tsim nyog rau kev sib txuas luv luv ntawm cov ntaub ntawv chaw, kev siv ntau yam, muaj zog sib pauv peev xwm ntawm kev sib koom ua ke.
2. Kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig: Cov khoom siv sab hauv ntawm cov kab hluav taws xob ceev yog tooj liab. Cov tooj liab cable muaj cov txiaj ntsig zoo thaum tshav kub kub dissipation thiab txuag hluav taws xob thiab kev tiv thaiv ib puag ncig.
3. Kev siv hluav taws xob tsawg: kev siv hluav taws xob tsawg ntawm kev kub ceev cable. Txij li thaum lub passive cable tsis xav tau lub zog, lub zog siv yuav luag 0. Lub zog noj ntawm cov kab hluav taws xob nquag feem ntau yog nyob ib puag ncig 440mW.
4. Tus nqi qis: tooj liab cables yog pheej yig dua li fiber ntau, yog li siv cov kab hluav taws xob ceev tuaj yeem txo cov nqi xaim ntawm tag nrho cov ntaub ntawv chaw.
AOC
AOC Active Cables yog kev sib txuas lus Cables tawm ntawm cov teeb liab hluav taws xob hloov mus rau hauv Optical signals lossis rau hauv hluav taws xob teeb liab nrog kev pab los ntawm lwm lub zog thaum sib txuas lus. Optical transceivers ntawm ob kawg ntawm Cables muab kho qhov muag hloov dua siab tshiab thiab kho qhov muag kis tau tus mob.
QSFP + AOCactive optical fiber luv luv, yog ib tug ntau yam channel cov ntaub ntawv kev sib txuas lus thiab interconnect daim ntawv thov tsim los ntawm kev ua tau zoo integrated cable los ua ke cov khoom, txhua lub teeb liab kev taw qhia muaj plaub cov ntaub ntawv raws, nyob rau hauv ib tug module nyob rau hauv 40 GBPS bandwidth sum, txhua channel yuav ua hauj lwm ntawm 10 GBPS ceev. , kev sib txuas lus deb ntawm 1 mus rau 100 m, yog tsim rau super computer thiab raws li SDR, DDR thiab QDR InfiniBand txheem daim ntawv thov. QSFP + AOC yog cov khoom tseem ceeb kom paub txog kev sib txuas ntawm qhov muag sib txuas. Nws yog tsim los ntawm ob lub high-speed 40G parallel optical modules txuas nrog ribbon OM3 optical cable (nrog plaub 850nm VCSEL transmitting raws thiab plaub tus PIN txais raws, ob qho tib si ntawm tus nqi ntawm 10Gbps).
