Kugawa kwa chingwe chothamanga kwambiri cha DAC wamba

Chingwe cha DAC chothamanga kwambiri(Chingwe Cholumikizira Molunjika) nthawi zambiri chimamasuliridwa kuti chingwe cholunjika, chingwe cha mkuwa cholumikizira mwachindunji kapena chingwe chothamanga kwambiri. Chimatanthauzidwa ngati njira yolumikizira yotsika mtengo ya mtunda waufupi yomwe imalowa m'malo mwa ma module optical. Malekezero onse awiri a chingwe chothamanga kwambiri ali ndi ma module. Ma Cable assemblies, ma ports osasinthika, mitu ya ma module ndi ma copper cables sangalekanitsidwe, koma poyerekeza ndi ma optical module active optical cables (Active Optical Cables), ma connector modules pa ma high-speed cables alibe ma lasers okwera mtengo komanso zida zina zamagetsi, kotero kusunga ndalama zambiri pakugwiritsa ntchito mphamvu pa ntchito za mtunda waufupi. Ndi liwiro lapamwamba la Ethernet, cloud computing, Internet of Things, ndi virtual data centers, zofunikira zambiri zayikidwa pa operators data center. Deta ya liwiro ili panjira yopita ku 400G, kotero kuwonjezera pa kulumikizana mkati mwa 3-5m mu seva, DAC ingagwiritsidwenso ntchito (mamita 5-7 amafunika kugwiritsa ntchito zipangizo zapadera zotetezera kuti akwaniritse zofunikira za khalidwe). Kulumikizana kupitirira mtunda uwu nthawi zambiri kumachitika ndi AOC.

10G SFP+ kupita ku SFP+ Liwiro Lalikulu Chingwe

10G SFP+ kupita ku SFP+ DAC imagwiritsa ntchito chingwe cha twinaxial chosagwira ntchito ndipo imalumikizana mwachindunji ndi gawo la SFP+, lomwe lili ndi kuchuluka kwakukulu, mphamvu yotsika, mtengo wotsika, komanso kuchedwa kochepa.

Ndi mitundu iti ya zingwe zothamanga kwambiri za 10G SFP+ kupita ku SFP+ zomwe zilipo?

Kawirikawiri, pali mitundu itatu ya zingwe zothamanga kwambiri za 10G SFP+ kupita ku SFP+:

Chingwe cha 10G SFP+ chapamwamba kwambiri (DAC),

Chingwe cha 10G SFP+ Chogwira Ntchito cha Copper Core High Speed ​​​​(ACC),

Chingwe Chogwira Ntchito cha 10G SFP+ (AOC),

Ndi oyenera kulumikizana ndi netiweki mkati mwa rack ndi pakati pa ma racks oyandikana ndipo ndi otsika mtengo kwambiri.

Chingwe cha SFP+ passive copper core chothamanga kwambiri chimapereka kulumikizana kwa magetsi mwachindunji pakati pa malekezero awiri a chingwe chogwirizana, ndipo mtunda wolumikizira ukhoza kufika mamita 12. Komabe, chifukwa cha kulemera kwakukulu kwa chingwecho komanso vuto la kukhulupirika kwa chizindikiro, kutalika kwake kogwiritsidwa ntchito nthawi zambiri kumakhala pakati pa mamita 7 ndi 10.

Chingwe cha 40G QSFP+ kupita ku QSFP+ Chothamanga Kwambiri

Chingwe cha 40G chothamanga kwambiri (DAC) chimatanthauza chingwe cholumikizira chokhala ndi ma transceivers a fiber optic mbali zonse ziwiri, chomwe chingafikire kutumiza deta ya 40Gbps ndipo ndi njira yotsika mtengo yolumikizirana mwachangu kwambiri. Zingwe zodziwika bwino za 40G zothamanga kwambiri zitha kugawidwa m'mitundu itatu: 40G QSFP+ kupita ku QSFP+DAC, 40GQSFP+ kupita ku 4*SFP+DAC, ndi 40GQSFP+ kupita ku 4XFP+DAC.

40G QSFP+ kupita ku QSFP+ DAC imapangidwa ndi ma transceiver awiri a 40G QSFP+ optical ndi mawaya amkuwa. Chingwe chothamanga kwambiri ichi chingagwiritsidwe ntchito polumikiza madoko a 40G QSFP+ omwe alipo kale ndi madoko a 40G QSFP+, nthawi zambiri mkati mwa mtunda wa mamita 7 okha.

40G QSFP+ mpaka 4×SFP+ DAC imapangidwa ndi transceiver imodzi ya 40G QSFP+ optical, waya wa mkuwa ndi ma transceiver anayi a 10G SFP+. Mbali imodzi ndi mawonekedwe a 40G QSFP+, omwe amakwaniritsa zofunikira za SFF-8436, ndipo mbali inayo ndi mawonekedwe anayi a 10G SFP+. , mogwirizana ndi zofunikira za SFF-8432, zomwe zimagwiritsidwa ntchito kwambiri polumikiza zida za 40G ndi 10G (NIC/HBA/CNA, zida zosinthira ndi seva), malinga ndi zomwe kasitomala amafuna kutalika kwa zingwe mbali zonse ziwiri, nthawi zambiri mkati mwa 7m yokha. Kutalika, pakadali pano ndikotsika mtengo komanso kosavuta kukwaniritsa kusintha kwa switch port.

40G QSFP+ mpaka 4XFP DAC imapangidwa ndi transceiver imodzi ya 40G QSFP+ optical, waya wa mkuwa ndi ma transceiver anayi a 10G XFP optical. Popeza transceiver ya XFP fiber optic ilibe muyezo wa chingwe cha mkuwa cha DAC, chiwongola dzanja chomwe chipangizocho chimapereka ndi chochepa, ndipo kutayika kwa chingwecho ndi kwakukulu kwambiri. Chingagwiritsidwe ntchito potumiza ma mtunda waufupi, nthawi zambiri mkati mwa mtunda wa 2m. Chifukwa chake, chingwe chothamanga kwambiri ichi chingagwiritsidwe ntchito polumikiza ma doko a 40G QSFP+ omwe alipo ku ma doko anayi a XFP.

Chingwe cha 25G SFP28 kupita ku SFP28 Chothamanga Kwambiri

25G SFP28 kupita ku SFP28 DAC imatha kupatsa makasitomala 25G kuthekera kolumikizirana kwa data kwa bandwidth yayikulu, mogwirizana ndi muyezo wa IEEE P802.3 ndi Ethernet ndi SFF-8402 SFP28, ndipo imagwiritsidwa ntchito kwambiri m'malo osungira deta kapena malo osungira ma supercomputing.

Chingwe Chothamanga Kwambiri cha 100G QSFP28 kupita ku QSFP28

100G QSFP28 kupita ku QSFP28 DAC imatha kupatsa makasitomala mwayi wolumikizirana kwa data wa 100G high-bandwidth, kupereka njira zinayi za duplex, njira iliyonse imatha kuthandizira mpaka 25Gb/s, ndipo bandwidth yosonkhanitsira ndi 100Gb/s, mogwirizana ndi zomwe SFF-8436 imafotokoza, zomwe zimagwiritsidwa ntchito polumikiza zida ndi madoko a QSFP28.

Chingwe cha 100G QSFP28 mpaka 4*SFP28 Chothamanga Kwambiri

Malekezero amodzi a 100G QSFP28 mpaka 4 SFP28 DAC ndi mawonekedwe a 100G QSFP28, ndipo malekezero ena ndi ma interface a 4 25G SFP28, omwe angapatse makasitomala mphamvu zolumikizira deta ya 100G yapamwamba, mogwirizana ndi miyezo ya SFF-8665/SFF-8679, IEEE 802.3bj ndi InfinibandEDR, Amagwiritsidwa ntchito kwambiri m'malo osungira deta kapena malo osungira ma super computing.
