40KM 40G QSFP + Module nziza ya Transceiver
UwitekaHUAQ40Eni transceiver module yagenewe 40Km optique itumanaho.Igishushanyo cyujuje 40GBASE-ER4 ya IEEE P802.3ba.Module ihindura imiyoboro 4 yinjiza (ch) yamakuru yumuriro wa 10Gb / s kuri 4 ya CWDM ya optique, kandi ikagwiza mumurongo umwe wa 40Gb / s optique.Ibinyuranye, kuruhande rwabakiriye, module optique de-multiplexes 40Gb / s yinjiza mumirongo 4 ya CWDM yerekana ibimenyetso, ikabihindura kumiyoboro 4 isohora amakuru yumuriro.
Uburebure bwo hagati bwimiyoboro 4 ya CWDM ni 1271, 1291, 1311 na 1331 nm nkabanyamuryango ba gride ya CWDM yumurongo wasobanuwe muri ITU-T G694.2.Irimo duplex LC ihuza interineti ya optique hamwe na 38-pin ihuza amashanyarazi.Kugirango ugabanye optique ikwirakwizwa muri sisitemu ndende, fibre imwe-imwe (SMF) igomba gukoreshwa muriyi module.
Igicuruzwa cyashizweho nuburyo bugaragara, optique / amashanyarazi ihuza hamwe nuburyo bwo kwisuzumisha hifashishijwe sisitemu ya QSFP Amasezerano menshi (MSA).Yashizweho kugirango ihuze imikorere ikaze yo hanze ikora harimo ubushyuhe, ubushuhe na EMIinterference.
Module ikorera kumurongo umwe + 3.3V itanga amashanyarazi hamwe na LVCMOS / LVTTL ibimenyetso byo kugenzura isi yose nka Module Present, Reset, Interrupt na Power Power Mode irahari hamwe na module.Imigaragarire ya 2-wire irahari yo kohereza no kwakira ibimenyetso byinshi bigenzura no kubona amakuru yo kwisuzumisha.Imiyoboro ya buri muntu irashobora gukemurwa kandi imiyoboro idakoreshwa irashobora gufungwa kugirango igishushanyo mbonera cyoroshye.
Iki gicuruzwa gihindura imiyoboro 4 yumurongo wa 10Gb / s mumashanyarazi yinjiza mumashanyarazi ya CWDM optique (urumuri), hamwe na moteri ya 4-yumurongo wa Distribution Feedback Laser (DFB) array.Umucyo uhujwe nibice bya MUX nkamakuru ya 40Gb / s, ikwirakwiza hanze ya transmitter kuva muri SMF.Module yakira yakira 40Gb / s CWDM yerekana ibimenyetso byinjiza, kandi de-multiplexes mumiyoboro 4 ya 10Gb / s hamwe nuburebure butandukanye.Buri mucyo wumurambararo ukusanywa na fotodiode ya avalanche yihariye (APD), hanyuma igasohoka nkamakuru yamashanyarazi nyuma yo kongerwaho mbere na TIA hanyuma ikongerwaho na post amplifier.
UwitekaHUAQ40Eyateguwe hamwe nibintu bifatika, optique / amashanyarazi hamwe na sisitemu yo kwisuzumisha ukurikije QSFP Amasezerano menshi (MSA).Yashizweho kugirango ihuze imikorere ikaze yo hanze irimo ubushyuhe, ubushuhe hamwe na EMI kwivanga.Module itanga imikorere ihanitse cyane hamwe nibiranga kwishyira hamwe, bigerwaho hifashishijwe ibice bibiri byuruhererekane.
