Igishushanyo cyujuje 40GBASE-ER4 ya IEEE P802.3ba. Module ihindura imiyoboro 4 yinjiza (ch) ya 10Gb / s yumuriro wamashanyarazi kuri 4 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 irimo ubushyuhe, ubushuhe hamwe na EMI kwivanga. 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. JHA-QC40 yateguwe hamwe nibintu bifatika, guhuza optique / amashanyarazi hamwe nuburyo bwo kwisuzumisha hifashishijwe imibare ukurikije QSFP Amasezerano menshi (MSA). Yashizweho kugirango ihuze imikorere ikaze yo hanze irimo ubushyuhe, ubushuhe hamwe na EMI kwivanga.
