40G QSFP+ kuQSFP+ High Speed Cable
A 40G high-speed cable (DAC) inoreva tambo yekubatanidza ine fiber optic transceivers kumativi ose maviri, iyo inogona kuwana 40Gbps kutumira data uye inodhura-inoshanda-yepamusoro-speed interconnection solution.Iyo yakajairika 40G high-speed cables inogona kugoverwa mumhando nhatu: 40G QSFP + kusvika QSFP + DAC, 40GQSFP + kusvika 4 * SFP + DAC, uye 40GQSFP + kusvika 4XFP + DAC.
40G QSFP + kuQSFP + DAC inoumbwa neaviri 40G QSFP + optical transceivers uye copper core waya.Iyi high-speed cable inogona kushandiswa kuona kuwirirana kwe40G QSFP + ports iripo kune 40G QSFP + ports, kazhinji mukati me7m chete.chinhambwe.
40G QSFP + kusvika 4 × SFP + DAC inoumbwa neimwe 40G QSFP + optical transceiver, copper core wire uye ina 10G SFP + optical transceivers.Imwe magumo ndeye 40G QSFP + interface, iyo inosangana nezvinodiwa zveSFF-8436, uye imwe magumo mana 10G SFP + interfaces., zvinoenderana nezvinodiwa zveSFF-8432, inonyanya kushandiswa kuona kubatana pakati pe40G ne10G midziyo (NIC/HBA/CNA, chinja midziyo uye sevha), zvinoenderana nezvinodiwa nemutengi pakureba kwetambo kumativi ese, kazhinji chete mukati me7m.Distance, parizvino ndiyo yakanyanya hupfumi uye iri nyore kuwana switch port kutendeuka.
Iyo 40G QSFP + kusvika ku4XFP DAC inoumbwa ne40G QSFP + optical transceiver, copper core wire uye ina 10G XFP optical transceivers.Sezvo iyo XFP fiber optic transceiver isina iyo DAC yemhangura tambo yakajairwa, muripo wechiratidzo wakapihwa nemudziyo wakaderera, uye kurasikirwa kwetambo pachayo kwakakura kwazvo.Inogona kungoshandiswa kutapurirana nhambwe-pfupi, kazhinji mukati mechinhambwe che2m.Naizvozvo, iyi high-speed cable inogona kushandiswa kuInterconnects iripo 40G QSFP + ports kusvika 4 XFP ports.
25G SFP28 kusvika kuSFP28 High Speed Cable
25G SFP28 kuSFP28 DAC inogona kupa vatengi vane 25G yakakwirira-bandwidth data interconnection simba, maererano neIEEE P802.3by Ethernet standard uye SFF-8402 SFP28, uye inoshandiswa zvakanyanya munzvimbo yedata kana supercomputing centre system scenarios.
100G QSFP28 kuQSFP28 High Speed Cable
100G QSFP28 kuQSFP28 DAC inogona kupa vatengi vane 100G yakakwirira-bandwidth data interconnection simba, kupa 4 duplex channels, chiteshi chimwe nechimwe chinogona kutsigira kusvika ku25Gb / s kushanda kwehuwandu, uye kuunganidza bandwidth ndeye 100Gb / s, maererano neSFF-8436. yakatarwa, inoshandiswa muKubatana pakati pemidziyo ine QSFP28 ports.
100G QSFP28 kusvika 4 * SFP28 High Speed Cable
Imwe magumo e100G QSFP28 kusvika 4 SFP28 DAC ndeye 100G QSFP28 interface, uye imwe mugumo ndeye 4 25G SFP28 interfaces, iyo inogona kupa vatengi vane 100G yakakwirira-bandwidth data interconnection capabilities, maererano neSFF-8665 / SFF-8679, IEEE 802.3bj uye InfinibandEDR zviyero, Inoshandiswa zvakanyanya mu data center kana super computing centre system scenarios.
