40KM 40G QSFP+ Module Transceiver Na gani
TheHUAQ40Eshi ne tsarin transceiver da aka tsara don aikace-aikacen sadarwa na gani mai nisan kilomita 40.Zane ya dace da 40GBASE-ER4 na ma'aunin IEEE P802.3ba.Tsarin yana canza tashoshi na shigarwa na 4 (ch) na bayanan lantarki na 10Gb/s zuwa sigina na gani na 4 CWDM, kuma ya ninka su cikin tashoshi ɗaya don watsawar gani na 40Gb/s.Komawa, a gefen mai karɓa, ƙirar ƙirar tana ƙaddamar da shigarwar 40Gb/s cikin siginar tashoshi 4 CWDM, kuma yana canza su zuwa bayanan lantarki na tashar tashar tashoshi 4.
Matsakaicin tsayin tsayin tashoshi na 4 CWDM sune 1271, 1291, 1311 da 1331 nm a matsayin mambobi na grid na CWDM da aka ayyana a cikin ITU-T G694.2.Yana ƙunshe da mai haɗin LC mai duplex don mahaɗar gani da kuma mai haɗin fil 38 don ƙirar lantarki.Don rage tarwatsawar gani a cikin tsarin dogon ja da baya, dole ne a yi amfani da fiber-mode fiber (SMF) a cikin wannan tsarin.
An ƙirƙira samfurin tare da nau'i nau'i, haɗin gani/lantarki da kuma dubawar bincike na dijital bisa ga Yarjejeniyar Maɓuɓɓuka Maɗaukaki na QSFP (MSA).An ƙera shi don saduwa da mafi tsananin yanayin aiki na waje gami da zafin jiki, zafi da tsangwama EMI.
Tsarin yana aiki daga wutar lantarki + 3.3V guda ɗaya da LVCMOS / LVTTL siginar sarrafawa na duniya kamar Module Present, Sake saitin, Katsewa da Yanayin Ƙarfin Wuta suna samuwa tare da kayayyaki.Akwai keɓancewar siriyal mai waya 2 don aikawa da karɓar ƙarin hadaddun siginonin sarrafawa da samun bayanan bincike na dijital.Ana iya magance tashoshi guda ɗaya kuma ana iya rufe tashoshin da ba a yi amfani da su ba don mafi girman sassaucin ƙira.
Wannan samfurin yana juyar da bayanan shigar da wutar lantarki ta tashar 4-tashar 10Gb/s zuwa siginonin gani na CWDM (haske), ta hanyar tsararriyar Rarraba Rarraba Feedback Laser (DFB).Hasken yana haɗuwa da sassan MUX azaman bayanan 40Gb/s, yana yaduwa daga tsarin watsawa daga SMF.Samfurin mai karɓa yana karɓar shigarwar siginar gani na 40Gb/s CWDM, kuma yana lalata shi cikin tashoshi 10Gb/s guda 4 guda 4 tare da tsayi daban-daban.Ana tattara kowane haske mai tsayi ta hanyar avalanche photodiode (APD), sannan a fitar dashi azaman bayanan lantarki bayan an inganta shi ta farko ta TIA sannan ta hanyar amplifier.
TheHUAQ40Ean ƙera shi tare da nau'i nau'i, haɗin gani/lantarki da dubawar bincike na dijital bisa ga Yarjejeniyar Maɓuɓɓuka Maɗaukaki na QSFP (MSA).An ƙera shi don saduwa da mafi tsananin yanayin aiki na waje gami da zafin jiki, zafi da tsangwama na EMI.Tsarin yana ba da babban aiki sosai da haɗin kai, ana iya samun dama ta hanyar hanyar sadarwa ta waya biyu.
