Amakhebuli angashintshiwe, ama-amplifiers alayini noma ama-retimers?

Amakhebuli angasebenzi, njengama-DAC, aqukethe izingxenye ze-elekthronikhi ezimbalwa kakhulu, asebenzisa amandla amancane kakhulu, futhi awonga imali. Ngaphezu kwalokho, ukubambezeleka kwayo okuphansi kuya ngokuya kubaluleka ngoba ngokuyinhloko sisebenza ngesikhathi sangempela futhi sidinga ukufinyelela kwesikhathi sangempela kudatha. Kodwa-ke, uma isetshenziswa ngobude obude nge-112Gbps PAM-4 (umkhiqizo we-pulse amplitude modulation technology) ku-800Gbps/port imvelo, ukulahleka kwedatha kwenzeka phezu kwezintambo ze-passive, okwenza kube nzima ukufeza amabanga wendabuko angu-56Gbps PAM-4 ngaphezu kwamamitha angu-2.

I-AEC ixazulule inkinga yokulahleka kwedatha ngama-retimers amaningi - eyodwa ekuqaleni neyodwa ekugcineni. Amasignali edatha adlula ku-AEC njengoba engena futhi ephuma, futhi abahlela kabusha balungisa amasignali edatha. Ama-retimers e-AEC akhiqiza amasiginali acace kakhudlwana, asuse umsindo, futhi akhulise amasiginali ukuze adlulise idatha ecacile, ecacile.

Olunye uhlobo lwekhebula eliqukethe ama-electronics asebenzayo ithusi elisebenzayo (ACC), elihlinzeka nge-amplifier eqondile esikhundleni se-retimer. Ama-retimers angasusa noma anciphise umsindo kumakhebuli, kodwa izikhulisa-msindo zolayini azikwazi. Lokhu kusho ukuthi ayilungisi isignali, kodwa ikhulisa kuphela isignali, ebuye ikhulise umsindo. Uyini umphumela wokugcina? Ngokusobala ama-amplifiers emigqa anikeza inketho yezindleko eziphansi, kodwa ama-retimers ahlinzeka ngesignali ecacile. Kukhona okuhle nokubi kukho kokubili, futhi yikuphi ongakhetha kuncike kuhlelo lokusebenza, ukusebenza okudingekayo, kanye nesabelomali.

Ezimeni ze-plug-and-play, ama-retimers anezinga eliphezulu lempumelelo. Isibonelo, amakhebuli anama-amplifaya emigqa angathwala kanzima ukuze agcine ukusebenza kwesignali okwamukelekayo lapho amaswishi e-top-of-rack (TOR) namaseva axhunywe kuzo ekhiqizwa abathengisi abahlukene. Abaphathi besikhungo sedatha cishe ngeke babe nesithakazelo ekuthengeni uhlobo ngalunye lwemishini kumthengisi ofanayo, noma ukushintsha imishini ekhona ukuze benze isixazululo somthengisi oyedwa ukusuka phezulu kuya phansi. Esikhundleni salokho, izikhungo eziningi zedatha zixuba futhi zifanise imishini evela kubathengisi abahlukene. Ngakho-ke, ukusetshenziswa kwezibali sikhathi kungenzeka kakhulu kuqalise ngempumelelo "i-plug and play" yamaseva amasha kungqalasizinda ekhona enamashaneli aqinisekisiwe. Kulokhu, ukubuyisela isikhathi kuphinde kusho ukonga izindleko ezibalulekile.
