Waɗanne kayan aiki ake buƙata don samarwa da gwaji na na'urorin gani na 800G?
Gwajin 800Gna'urorin ganiya haɗa da gwajin aikin karɓa da gwajin aikin watsawa. Jerin kayan aiki da dabaru na asali sune kamar haka:
1, Kayan aikin gwaji
Allon jigilar kaya na 1.1MCB
Saita allunan ɗaukar kaya guda biyu na MCB don sanya tsarin DUT da tsarin daidaitaccen bi da bi. Ana saka tsarin gani a cikin allon ɗaukar kaya kuma an haɗa shi da mitar lambar kuskure ta hanyar kebul na RF mai sauri. Allunan ɗaukar kaya guda biyu na iya tabbatar da 'yancin gwajin RX da gwajin TX. Idan ana amfani da gwajin loopback, ana buƙatar allon ɗaukar kaya ɗaya kawai. Tsarin gani na 800G yana buƙatar hanyar gani ta 8T8R, wanda ya dace da buƙatar nau'i-nau'i 16 na sigina daban-daban don Gold Finger, wanda ke nufin kebul na RF/allunan ɗaukar kaya guda 32.
1.2 Kayan Aikin Kula da Zafin Jiki
Allunan ɗaukar hoto na MCB galibi suna da na'urorin auna zafin jiki da ganowa don tallafawa aikin gwaji a yanayin zafi daban-daban. Ana ɗora kayan aikin sarrafa zafin jiki akan allon ɗaukar hoto na MCB na DUT. Haɗa na'urar sarrafa zafin jiki akan allon ɗaukar hoto na MCB na iya sauƙaƙa kayan aiki.
1.3 Mai nazarin lambar kuskure
Saita na'urorin gwaji guda biyu na kuskuren bit 800G don fitar da jerin PRBS da kuma fitar da gwaje-gwajen RX da TX bi da bi. Idan daidaitaccen tsarin gani yana goyan bayan jerin PRBS, zai iya adana na'urar gano kuskure bit ɗaya kuma ya yi amfani da kwamfutar sama don ba da umarni ga na'urar gani ta yau da kullun don aika jerin gwaje-gwajen. Gwajin RX na Tuki (gwajin kuskuren bit): Haifar da jerin gwaji, karɓi jerin dawowa, da kwatanta kuskuren tsakanin mai watsawa da mai karɓa, wato, kuskuren bit. Gwajin TX na Tuki (gwajin zane na ido): Haifar da jerin gwaji don DUT, kuma DUT yana fitar da haske bisa ga wannan jerin. Haɗakar ciki ta allon ɗaukar MCB da kayan aikin sarrafa zafin jiki a cikin na'urar nazarin lambar kuskure na iya ƙara sauƙaƙe kayan aikin.
Kayan Aikin Agogo na 1.4CDR
Ana aika siginar gani lokaci-lokaci, kuma CDR yana gano gefen wannan lokacin daga siginar gani.
1.5 Oscilloscope
Dangane da siginar lokaci da CDR ta bayar, ana haɗa bayanan siginar gani lokaci-lokaci don samar da zane na ido. Idan oscilloscope yana goyan bayan shigarwar guda 4 da gwajin 800G, to ana buƙatar raka'a biyu. Mafi tsada, idan kuna son adana kuɗi, kuna iya amfani da maɓallin haske don canzawa.
1.6Canjin gani
Canja hanyar gani tsakanin gwajin zane na ido da gwajin ƙarfi.
1.7Mita wutar lantarki ta gani
Auna ƙarfin gani na fitarwa, tashoshi 8. Ana iya haɗa na'urar auna wutar lantarki ta gani cikin maɓallin gani, wanda hakan zai sauƙaƙa kayan aiki.
1.8 Wutar lantarki ta DC
Samar da wutar lantarki mai ƙarfi ta DC ga kwamitin ɗaukar kaya na MCB.
2, Tsarin ginin tsarin gwaji
2.1. Gwajin aikin karɓar RX (ƙimar kuskuren bit, saurin amsawa)
Gudun sigina: Mai nazarin lambar kuskure 2 → Na'urar gani ta yau da kullun → Mai rage haske → DUT → Mai nazarin lambar kuskure 1
Kayan aiki masu mahimmanci: na'urar rage hasken haske (ana amfani da ita don duba wuraren wutar lantarki), na'urar hangen nesa ta yau da kullun (ana amfani da ita azaman tushen haske).
Manufa: Don auna ƙimar kuskuren bit na DUT a ƙarfin gani daban-daban ta hanyar canza adadin ragewa.
2.2. Gwajin aikin fitar da hayaki ta TX (zanen ido, ƙarfin gani)
Gudun sigina: Mai nazarin lambar kuskure 1 → DUT → Maɓallin gani → (mita wutar lantarki/oscilloscope+CDR)
Kayan aiki masu mahimmanci: Maɓallin gani (canza hanya), CDR (sake dawo da agogo, don siginar PAM4).
Manufa: Don tabbatar da ƙarfin hasken da aka fitar da kuma ingancin sigina (zanen ido ya kamata ya nuna "idanu" guda uku na PAM4).
3, Mahimman abubuwan da aka tsara musamman don gwajin 800G
Adadin tashar: 800G yana ɗaukar tashoshi 8 (8T8R), kuma yatsun ƙarfe na allon ɗaukar MCB suna buƙatar daidaitawa da nau'i-nau'i 16 na sigina daban-daban (kebulan RF 32).
Nau'in sigina: Don daidaita PAM4, dole ne a haɗa oscilloscope ɗin tare da kayan aikin CDR don ɗaukar hoton ido daidai.
Mafita Mai Sauƙi: Mai gano kurakurai zai iya haɗa ayyukan MCB da ayyukan sarrafa zafin jiki. Ana iya haɗa maɓallin gani tare da na'urar auna wutar lantarki ta gani. Idan ana amfani da gwajin baya na madauki (DUT kai tsaye), zai iya rage allon ɗaukar MCB ɗaya da kuma tsarin aiki na yau da kullun, amma abubuwan gwaji na iya zama iyakance.
4, Bayani kan muhimman kalmomi
PRBS: Jerin bazuwar ƙarya, yana kwaikwayon zirga-zirgar bayanai na gaske.
MCB: Allon ɗaukar kaya mai bin ƙa'idodin module, kayan gwaji.
CDR: Maido da bayanan agogo, cire agogo daga siginar gani.
Zane-zanen ido na PAM4: Tsarin bugun bugun mataki huɗu, zane-zanen ido yana gabatar da matakai huɗu (buɗe ido uku)
