Module optique nibikoresho byingenzi byuma bikoresho kugirango tumenye imiyoboro ihuza imiyoboro hagati yamakuru. Hamwe no kwiyongera kwumubare wicyambu nubucucike, ikiguzi cya module optique kizaba hafi kimwe cya kabiri cyikiguzi cyumuyoboro wa optique mukigo cyamakuru. Kugeza ubu, ikorana buhanga rya 100G ryakoreshejwe cyane mubigo bishya byubatswe byamasosiyete akomeye ya interineti, na 400G ikorana buhanga rizakoreshwa cyane mumyaka 1-2 iri imbere.Nuko rero, tekinoroji yo gushyira mubikorwa ya 400G optique module yabaye intandaro yinganda.
Kubirebana nuburebure bwumucyo, 400G module yumucyo irashobora kugabanywa muburyo bwinshi (MM) nuburyo bumwe (SM) .Mu bijyanye nuburyo bwo guhindura ibimenyetso, birashobora kugabanywa muri moderi ya NRZ na PAM4 (PAM4 nimwe nyamukuru kuri ubu) .Mu bijyanye nintera yo kohereza, 400G optique module irashobora kugabanywamo SR, DR, FR na LR. Kuva kumpapuro zipakira, module 400G optique irashobora kugabanywamo CDFP, CFP8, OSFP, qsfp-dd nibindi. Hasi nuburyo bwa tekinike ya 400G optique module.
Module ya optique ya 400G yambere yakoresheje imiyoboro 16-ya 25Gbps NRZ ishyirwa mubikorwa (nka 400g-sr16), ukoresheje CDFP cyangwa CFP8. Ibyiza bya NRZ nuko ishobora gutizwa muburyo bwa 25G NRZ ikuze kuri module ya optique ya 100G, ariko ikibi nuko ikenera imiyoboro 16 yikimenyetso kugirango ikwirakwizwa, hamwe nogukoresha ingufu nini nubunini, bidakwiriye kuri ikoreshwa rya data center.
Muri moderi ya optiki ya 400G, 8-umuyoboro wa 53GbpsPAM4 (400g-sr8, FR8, LR8) cyangwa umuyoboro wa 4G 106GbpsPAM4 (400g-dr4, FR4, LR4) ikoreshwa cyane cyane kugirango ugere kuri 400G ibimenyetso byerekanwa kuruhande rwa optique, na 8 -umuyoboro 53GbpsPAM4 ibimenyetso byamashanyarazi bikoreshwa kuruhande rwicyuma cyamashanyarazi, ufata uburyo bwo gupakira bwa OSFP cyangwa qsfp-dd. Ipaki zombi za OSFP na QSFP-DD zitanga 8 - umuyoboro wamashanyarazi wumurongo wamashanyarazi. Mugereranije, ingano ya pake ya qsfp-dd ni nto (bisa na 100G ya optique module ya QSFP28 isanzwe), ikaba ikwiranye nibisabwa na data center. Ingano ya pake ya OSFP nini nini, kuko irashobora gutanga ingufu nyinshi, kuburyo bukenewe kubitumanaho.
Igishushanyo gikurikira cyerekana ishyirwa mu bikorwa rya 400g-fr8 / LR8 na 400g-fr4
Reba：OSFPMSA Ibisobanuro bya OSFP OCTAL GIKORESHWA CY'INGENZI ZIKURIKIRA.）Birashobora kugaragara ko uruhande rwimbere ari 8-umuyoboro wa 53Gbps PAM4. Kuri 400g-sr8 / FR8 / LR8 nizindi module,
CDR (kugarura isaha) hamwe n'amashanyarazi / optique cyangwa optique / guhinduranya amashanyarazi bikorerwa gusa muri module ya optique. Kubwibyo, icyambu cya optique nacyo ni 8-umuyoboro wa 53Gbps PAM4, kimwe no gupima icyuma cyamashanyarazi. Kuri 400g-dr4 / FR4 / LR4 nizindi modul, hariho chip ya Gearbox imbere muri module optique igwiza ibyinjira byombi. ibyambu mu kimenyetso kimwe kandi ikabihindura ku mucyo, bityo umuvuduko wicyambu cya optique wikubye kabiri icyambu, aricyo kimenyetso 106GbpsPAM4.
