I-Skyward Telecom (BDC Cable Limited) iyaziqhenya ngokunikela ngekhwalithi ephezuluI-QSFP-DD kuya ku-2xQSFP56Ikhebula le-DAC lokuphuma liyathengiswa.Le ntambo yokuphuma idizayinelwe ukuhlangabezana nesidingo esikhulayo sokuxhunywa kwe-rack yesivinini esikhulu ezikhungweni zedatha nasezindaweni zeseva.Ikhebuli iyakwazi ukuletha izimbobo ze-100GbE futhi ingaphinde ihlukaniswe ibe izimbobo ezine ze-25GbE noma isekele i-40GbE, inikeze isisombululo sokuxhuma esisebenza ngezindlela eziningi nesezidingo zenethiwekhi yesimanje.
Incazelo Yomkhiqizo
Le khebuli yokuphumula iyatholakala ekucushweni okungu-400Gbps (QSFP-DD) kuya ku-2x 200Gbps (2x QSFP56).Ihambisana namazinga e-IEEE 802.3cd 50GBase-CR kanye ne-100GBase-CR2 futhi inamamajini amakhulu esignali yobuqotho, ehlinzeka ngezixazululo zokuxhumanisa komkhawulokudonsa ophezulu wezinhlelo zokusebenza eziphakeme kakhulu.Lokhu kuqinisekisa ukuthi amakhebula ahlanganisa ahlinzeka ngoxhumano oluthembekile, oluphumelelayo oluhlangabezana nezimfuneko eziqinile zezindawo zesimanje zesikhungo sedatha.

| Izinga Lokushisa | 0-70o C |
| Ukunqanyulwa kwekhebula | Ukuhlolwa kwasembonini okungu-100% okuhlanganisa ubuqotho besignali obuphelele kanye nokulandeleka kwenombolo ye-serial kusetshenziswa ama-Advanced Manufacturing Execution Systems |
Izixazululo zokuxhuma ezihlukahlukene
I-Skyward Telecom (i-BDC Cable Limited) inikeza izixazululo nemikhiqizo yesikhungo sedatha enendawo eyodwa okuhlanganisa Amakhebula e-Serial Attached SCSI, Amakhebula Anamathisele Kakhulu Ethusi, AmaCable Optical Active kanye namaCable akwaNokia/Ericsson.Inkampani igxile ekuhlinzekeni izixazululo ezisezingeni eliphezulu, ezinokwethenjelwa zokuxhuma futhi izimisele ukuhlangabezana nezidingo ezihlukahlukene zabaqhubi besikhungo sedatha nabaphathi benethiwekhi.
Hlangana nezindinganiso zomkhakha
Amakhebuli e-DAC aphumayo anikezwa i-Skyward Telecom aklanyelwe ukuhlangabezana nezindinganiso zomkhakha, ukuqinisekisa ukuhambisana nokwethembeka.Ikhebuli iyakwazi ukuletha ukuxhumeka kwesivinini esikhulu kuyilapho igcina ubuqotho besignali ukuze ihlangabezane nezidingo ezihlala zishintsha zengqalasizinda yenethiwekhi yesimanje.Lokhu kwenza kube kuhle ezinhlanganweni ezifuna ukuthuthukisa ukuxhumana kwazo kwesikhungo sedatha ngesixazululo esisebenza kahle kakhulu.
Izixazululo zokuxhuma komkhawulokudonsa othuthukisiwe
Ikhebula le-DAC le-QSFP-DD ukuya ku-2xQSFP56 lihlinzeka ngesixazululo esithuthukisiwe soxhumano lomkhawulokudonsa, okuvumela izinhlangano ukuthi zihlangabezane nesidingo esikhulayo sokudluliswa kwedatha ngesivinini esikhulu nokuxhumana kwenethiwekhi.Ikhono lekhebula lokusekela ukuxhumana kwe-400GbE linikeza isixazululo sobufakazi besikhathi esizayo kubaqhubi besikhungo sedatha abafuna ukuhlala ngaphambi kwejika emandleni enethiwekhi.
Ekuphetheni
Kafushane, izintambo eziphezulu ze-QSFP-DD kuya kwezingu-2xQSFP56 eziphumayo ze-DAC ezivela ku-Skyward Telecom (BDC Cable Limited) zihlinzeka ngesisombululo sokuxhuma esiguquguqukayo nesisebenzayo sesikhungo sedatha yesimanje kanye nezimo zeseva.Igxile ekuhlangabezaneni nezindinganiso zomkhakha kanye nokuletha ukusebenza okuthembekile, le ntambo ilungele izinhlangano ezifuna ukuthuthukisa ingqalasizinda yazo yenethiwekhi.Kungakhathaliseki ukuthi isetshenziselwa ukuxhumana kwe-rack enesivinini esiphezulu noma ukusekela ukuxhumana kwe-400GbE, le ntambo yokuphumula iletha ukuguquguquka nokusebenza okudingekayo ukuze kuhlangatshezwane nezidingo ezihlala zishintsha zamanethiwekhi anamuhla.
