Zvisinei, nekuda kwehuremu hwakanyanya hwewaya uye tichifunga nezvedambudziko rekuvimbika kwechiratidzo, kureba kwekushandiswa kwayo kunowanzo ganhurira pakati pe7m ne10m.
40G QSFP+ kuenda kuQSFP+ Cable Inomhanya Zvikuru
Tambo ye40G inomhanya zvakanyanya (DAC) inoreva tambo inobatanidza ine ma transceivers e fiber optic kumativi ese, iyo inogona kusvitsa data re40Gbps uye inzira yekubatanidza data nekukurumidza inodhura zvishoma. Tambo dzinonyanya kushandiswa dze40G dzinomhanya zvakanyanya dzinogona kukamurwa kuita mhando nhatu: 40G QSFP+ kuenda kuQSFP+DAC, 40GQSFP+ kuenda ku4*SFP+DAC, uye 40GQSFP+ kuenda ku4XFP+DAC.
40G QSFP+ kuenda kuQSFP+ DAC ine ma transceiver maviri e40G QSFP+ optical uye waya dzemhangura. Iyi waya inomhanya zvikuru inogona kushandiswa kuita kuti ma ports e40G QSFP+ aripo aenderane ne 40G QSFP+ ports, kazhinji kacho iri mukati memamita manomwe chete.
40G QSFP+ kusvika ku4×SFP+ DAC inoumbwa ne40G QSFP+ optical transceiver imwe chete, copper core wire uye mana 10G SFP+ optical transceivers. Imwe mugumo i40G QSFP+ interface, iyo inosangana nezvinodiwa neSFF-8436, uye imwe mugumo i4G SFP+ interfaces. , zvichienderana nezvinodiwa neSFF-8432, inonyanya kushandiswa kuita kuti 40G ne10G zvishandiso zvive pamwe chete (NIC/HBA/CNA, switch equipment neserver), zvichienderana nezvinodiwa nemutengi pakureba kwetambo kumativi ese, kazhinji mukati me7m chete. Kureba, parizvino ndiyo inonyanya kudhura uye iri nyore kuita shanduko yeswitch port.
40G QSFP+ kusvika ku4XFP DAC inoumbwa netransceiver imwe chete ye40G QSFP+ optical, copper core wire uye mana e10G XFP optical transceivers. Sezvo XFP fiber optic transceiver isina DAC copper cable standard, muripo wechiratidzo unopiwa nemudziyo wacho wakaderera, uye kurasikirwa kwetambo pachayo kwakakura zvikuru. Inogona kushandiswa chete pakutumira mafambiro ari kure, kazhinji iri mukati memamita maviri. Nokudaro, iyi tambo inomhanya zvikuru inogona kushandiswa pakubatanidza maports e40G QSFP+ aripo kune maports mana eXFP.
25G SFP28 kuenda kuSFP28 Cable Inomhanya Zvikuru
