Mu rwego rw'itumanaho, imiyoboro y'amashanyarazi ikwirakwiza insinga z'icyuma irabujijwe cyane kubera ibintu nko kwivanga kwa electronique, guhuza amakode hagati no gutakaza, hamwe n'amafaranga yo gukoresha insinga.
Kubera iyo mpamvu, imiyoboro ya optique yavutse. Ihererekanyabubasha rifite ibyiza byo kwaguka cyane, ubushobozi bunini, kwishyira hamwe byoroshye, gutakaza bike, guhuza amashanyarazi meza, nta kambuka, uburemere bworoshye, ubunini buto, nibindi, bityo rero optique ikoreshwa cyane mugukwirakwiza ibimenyetso bya digitale.
Imiterere yibanze ya optique module
Muri byo, optique module nigikoresho cyibanze mugukwirakwiza fibre optique, kandi ibipimo byayo bitandukanye bigena imikorere rusange yo kohereza. Modire ya optique niyitwara ikoreshwa mugukwirakwiza hagati yahinduranigikoresho, kandi umurimo wacyo nyamukuru nuguhindura ibimenyetso byamashanyarazi byigikoresho mubimenyetso bya optique kumpera yohereza. Imiterere y'ibanze igizwe n'ibice bibiri: “ibice bitanga urumuri n'umuzunguruko wacyo” na “ibice byakira urumuri n'umuzunguruko wakira”.
Module optique ikubiyemo imiyoboro ibiri, aribyo umuyoboro wohereza hamwe numuyoboro wakira.
Ibigize hamwe nihame ryakazi ryumuyoboro
Umuyoboro wogukwirakwiza module ya optique ugizwe namashanyarazi yerekana ibimenyetso byamashanyarazi, umuzunguruko wa laser, umuzenguruko uhuza umuzenguruko hamwe nibikoresho bya laser TOSA.
Ihame ryakazi ryayo ni amashanyarazi yinjiza umuyoboro wogukwirakwiza, guhuza ibimenyetso byamashanyarazi birangizwa binyuze mumuzunguruko wamashanyarazi, hanyuma umuzunguruko wa laser mumurongo woguhindura ugahinduka, hanyuma igice gihuye na impedance gikoreshwa mukubangamira bihuye kugirango urangize modulation na drive yikimenyetso, hanyuma hanyuma wohereze laser (TOSA) electro-optique ihinduka mubimenyetso bya optique yo kohereza ibimenyetso bya optique.
Ibigize hamwe nihame ryakazi ryumuyoboro wakira
Umuyoboro wa optique wakiriye umuyoboro ugizwe na optique ya detector ya optique ya ROSA (igizwe na diode ya fotodetection (PIN), transimpedance amplifier (TIA)), inzitizi zihuye n’umuzunguruko, kugabanya imiyoboro ya amplifier hamwe n’amashanyarazi yerekana amashanyarazi.
Ihame ryakazi ryayo nuko PIN ihindura ibimenyetso bya optique byakusanyirijwe mubimenyetso byamashanyarazi muburyo bukwiranye. TIA ihindura iki kimenyetso cyamashanyarazi mukimenyetso cya voltage, kandi ikongerera ibimenyetso byahinduwe na voltage kuri amplitude isabwa, ikanayigeza kuri limiter binyuze mumuzunguruko uhuza inzitizi Umuyoboro wa amplifier urangiza kongera kwongera no guhindura ibimenyetso, utezimbere ibimenyetso- igipimo cy-urusaku, kigabanya igipimo cyamakosa, hanyuma amaherezo yumuzunguruko wamashanyarazi urangiza ibimenyetso bisohoka.
Ikoreshwa rya module optique
Nka gikoresho cyibanze cyo guhinduranya amafoto mu itumanaho rya optique, modul optique ikoreshwa cyane mubigo byamakuru. Ibigo byamakuru gakondo bikoresha cyane cyane 1G / 10G modulike yihuta ya optique, mugihe ibicu byamakuru yibicu bikoresha cyane 40G / 100G byihuta. Hamwe nibintu bishya bisabwa nka videwo isobanura cyane, isakaza imbonankubone, na VR ituma iterambere ryihuta ry’umuvuduko w’urusobe rw’isi, hasubijwe imigendekere y’iterambere ry’ejo hazaza, ibisabwa bigaragara nko kubara ibicu, serivisi za Iaa S, hamwe namakuru makuru ashyira hejuru cyane kuri data center imbere yohererezanya amakuru, Bizabyara modul optique hamwe nigipimo cyinshi cyo kohereza mugihe kizaza.
Mubisanzwe, iyo duhisemo modul optique, dusuzuma cyane cyane ibintu nka sisitemu yo gusaba, ibisabwa byo kohereza amakuru, ubwoko bwimbere, hamwe nintera yohereza (optique ya fibre, imbaraga za optique, uburebure bwumurongo hagati, ubwoko bwa laser) nibindi bintu.
