40KM 40G QSFP+ Na'urar Canja wurin Na'ura Mai Nuni
TheHUAQ40Ewani tsarin transceiver ne da aka tsara don aikace-aikacen sadarwa ta gani na 40Km. Tsarin ya yi daidai da 40GBASE-ER4 na ma'aunin IEEE P802.3ba. Tsarin yana canza tashoshi 4 na shigarwa (ch) na bayanan lantarki na 10Gb/s zuwa siginar gani na CWDM guda 4, kuma yana ninka su zuwa tashoshi ɗaya don watsawa ta gani na 40Gb/s. A gefe guda, a gefen mai karɓa, tsarin yana cire shigarwar 40Gb/s zuwa siginar tashoshi CWDM guda 4 ta hanyar gani, kuma yana canza su zuwa bayanai na lantarki na fitarwa ta tashoshi 4.
Tsawon tsayin tsayin tsakiya na tashoshin CWDM guda huɗu sune 1271, 1291, 1311 da 1331 nm a matsayin membobin grid ɗin tsawon tsayin CWDM da aka ayyana a cikin ITU-T G694.2. Ya ƙunshi haɗin LC mai duplex don haɗin gani da kuma haɗin fil 38 don haɗin lantarki. Don rage yaɗuwar gani a cikin tsarin dogon zango, dole ne a yi amfani da fiber mai yanayi ɗaya (SMF) a cikin wannan module.
An tsara samfurin tare da yanayin tsari, haɗin gani/na lantarki da kuma hanyar sadarwa ta dijital bisa ga Yarjejeniyar Tushe Mai Yawa ta QSFP (MSA). An tsara shi don dacewa da mafi tsananin yanayin aiki na waje, gami da zafin jiki, danshi da tsangwama na EMI.
Tsarin yana aiki daga wutar lantarki guda ɗaya +3.3V kuma siginar sarrafawa ta duniya ta LVCMOS/LVTTL kamar Module Present, Reset, Interrupt da Low Power Mode suna samuwa tare da kayan aikin. Akwai hanyar sadarwa ta waya biyu don aika da karɓar siginar sarrafawa masu rikitarwa da kuma samun bayanan ganewar asali na dijital. Ana iya magance tashoshi daban-daban kuma ana iya rufe tashoshin da ba a yi amfani da su ba don mafi girman sassaucin ƙira.
Wannan samfurin yana canza bayanan shigarwar lantarki na tashoshi 4 na 10Gb/s zuwa siginar gani ta CWDM (haske), ta hanyar jerin Laser Distributed Feedback Laser (DFB) mai motsi 4. Ana haɗa hasken da sassan MUX a matsayin bayanai na 40Gb/s, yana yaɗuwa daga tsarin watsawa daga SMF. Tsarin mai karɓa yana karɓar shigarwar siginar gani ta 40Gb/s CWDM, kuma yana cire shi zuwa tashoshi 4 na 10Gb/s daban-daban tare da tsayi daban-daban. Kowane hasken tsayi ana tattara shi ta hanyar photodiode mai faɗi (APD), sannan a fitar da shi azaman bayanan lantarki bayan an ƙara shi da farko ta hanyar TIA sannan kuma ta hanyar amplifier post.
TheHUAQ40EAn ƙera shi da siffar tsari, haɗin gani/na lantarki da kuma hanyar gano bayanai ta dijital bisa ga Yarjejeniyar Tushe Mai Yawa ta QSFP (MSA). An ƙera shi don ya dace da mafi munin yanayin aiki na waje, gami da zafin jiki, danshi da tsangwama na EMI. Tsarin yana ba da babban aiki da haɗin fasali, wanda ake iya samu ta hanyar hanyar sadarwa ta waya biyu.
