Lihlahisoa tsena li kenyelletsa litsamaiso tse phahameng tsa board-to-board (sandwich), likopano tsa cable tse lebelo le holimo, liphanele tsa backplane le li-cable system, li-pini tse peli le li-socket system, likopano tsa cable tse sebetsang (tse bitsoang "mid-board optical transceivers" ho tataiso e ncha ea optical ea Samtec), le lihokelo tsa RF le likopano tsa cable.
Baqapi ba lisebelisoa tsa lebelo le phahameng (112 Gb / s data rate ka mocha PAM4, 224 e tlang) tse kang litsi tsa data, li-supercomputers, lisebelisoa tsa tlhahlobo tse ikemetseng, le litšoantšo tsa bongaka hangata li sebelisa likopano tsa cable tse lebelo ho fetisetsa boitsebiso bo bongata boitsebisong bo phahameng. litefiso.
Leha ho na le mefuta e fapaneng ea likopano tsa cable tse lebelo le holimo, bareki ba bangata ba totobatsa liphetoho ho lihlahisoa tsena tse tloaelehileng. Liphetoho tse tloaelehileng li kenyelletsa meralo e tloaelehileng ea PCB bakeng sa 'mapa oa phini bakeng sa lits'ebetso tse ikhethileng, ho beha lihlahla tse sireletsang ho pota-potile likhoele tsa mantlha tse sothehileng, kapa ho eketsa lileibole ho likhokahanyo le likhoele ho khetholla linomoro tsa likarolo kapa ho fana ka litaelo, ho bolela tse seng kae ho tse makholo tse ka bang teng. liphetoho tse ka etsoang.
Phetoho e 'ngoe e tsebahalang ke ho kopanya le ho bapisa pheletso ea 1 le lihokelo tsa 2 tsa karolo. Ka mohlala, sehokelo sa phanele sa Flyover® QSFP-DD se ka felisoe ho palo efe kapa efe ea lihokelo tse phahameng tsa "end-2" tse behiloeng haufi le chip. Baqapi ba hloka mefuta e fapaneng ea likhokahano bakeng sa litsamaiso tsa khokahano ea liphanele tse ka pele, tse bohareng le tse ka morao.
Litsamaiso tsa ho itšeha ka lebelo le phahameng li hloka moloko o latelang oa lihokelo tse sebetsang hantle. Leha ho le joalo, bahlahisi ba bangata ba ntse ba rala lits'ebetso tse "otlolohileng" joalo ka li-automation tsa indasteri, liroboto, lihlahisoa tse kentsoeng, le litsamaiso tsa pono le ts'ireletso. Hangata mabokose ana a sebelisa likhokahano tsa setso tsa mantlha, joalo ka li-terminals tsa poso (" lihokelo ") le liboto tsa socket. Moralo o batlang o le bonolo oa lihlahisoa tsena - hlobolisa line insulators polasetiki le centerlines bao e seng nyenyane (mohlala, 2.54 kapa 2.00mm le 1.00 kapa 0.80mm sekontiri se metsi) - etsa diphetolo bonolo le batlang ka potlako, 'me kahoo theko e tlaase.
Liphetoho tse tummeng li kenyelletsa polarization ea lipini tse ngata - ho tlosa lithapo - ho lumella keying, ho phalla ha moea, 'mapa oa matšoao, le sebaka se eketsehileng bakeng sa phetisetso ea matla kapa sebaka sa creepage le tumello ho finyella litekanyetso tsa polokeho le taolo.
