Pankhani yoyankhulirana, kutumizirana mawaya azitsulo kumakhala kochepa kwambiri chifukwa cha zinthu monga kusokoneza ma electromagnetic, inter-code crosstalk ndi kutayika, komanso mtengo wama waya.
Zotsatira zake, kufalikira kwa kuwala kunabadwa.Kutumiza kwa Optical kuli ndi zabwino za bandwidth yayikulu, mphamvu yayikulu, kuphatikizika kosavuta, kutayika pang'ono, kuyanjana kwamagetsi kwamagetsi, palibe crosstalk, kulemera kopepuka, kakang'ono, ndi zina zotere, kotero kutulutsa kwa kuwala kumagwiritsidwa ntchito kwambiri potumiza ma siginecha a digito.
Mapangidwe oyambira a Optical module
Pakati pawo, gawo la Optical ndilo chipangizo chachikulu mu kufala kwa fiber fiber, ndipo zizindikiro zake zosiyanasiyana zimatsimikizira momwe ntchitoyo ikugwiritsidwira ntchito.Optical module ndi chonyamulira chomwe chimagwiritsidwa ntchito pofalitsa pakati pa chosinthira ndi chipangizocho, ndipo ntchito yake yaikulu ndiyo kutembenuza chizindikiro chamagetsi cha chipangizocho kukhala chizindikiro cha kuwala pamapeto otumizira.Kapangidwe kake kamakhala ndi magawo awiri: "gawo lotulutsa kuwala ndi dera lake loyendetsa" ndi "gawo lolandila kuwala ndi dera lolandirira".
Optical module ili ndi njira ziwiri, zomwe ndi njira yotumizira ndi njira yolandirira.
Kapangidwe ndi mfundo yogwirira ntchito ya njira yopatsira
Njira yotumizira ya module ya optical imapangidwa ndi mawonekedwe amagetsi amagetsi amagetsi, laser drive circuit, impedance yofananira dera ndi gawo la laser TOSA.
Mfundo yake yogwirira ntchito ndi mawonekedwe amagetsi opangira njira yotumizira, kulumikiza kwa siginecha yamagetsi kumatsirizidwa kudzera mumayendedwe amagetsi, ndiyeno gawo loyendetsa laser munjira yotumizira limasinthidwa, kenako gawo lofananira la impedance limagwiritsidwa ntchito poletsa. kufananitsa kuti mutsirize kusinthasintha ndi kuyendetsa chizindikiro, ndipo potsiriza Tumizani kutembenuka kwa laser (TOSA) electro-optical kukhala siginecha ya kuwala kwa kufalikira kwa siginecha.
Kapangidwe ndi mfundo yogwirira ntchito ya njira yolandirira
Njira yolandirira ma module optical imakhala ndi gawo la optical detector ROSA (lopangidwa ndi photodetection diode (PIN), transimpedance amplifier (TIA)), impedance yofananira dera, kuchepetsa amplifier dera ndi mawonekedwe amagetsi amagetsi otulutsa mawonekedwe.
Mfundo yake yogwira ntchito ndi yakuti PIN imatembenuza chizindikiro chosonkhanitsidwa cha kuwala kukhala chizindikiro chamagetsi molingana.TIA imatembenuza siginecha yamagetsi iyi kukhala siginecha yamagetsi, ndikukulitsa siginecha yamagetsi yosinthidwa kukhala matalikidwe ofunikira, ndikuitumiza ku malire kudzera munjira yofananira yofananira Dera la amplifier limamaliza kukulitsanso ndikusinthanso siginecha, kuwongolera chizindikiro- to-phokoso chiŵerengero, amachepetsa pang'ono zolakwika mlingo, ndipo potsiriza magetsi mawonekedwe dera anamaliza linanena bungwe chizindikiro.
Kugwiritsa ntchito Optical module
Monga chipangizo chachikulu cha kutembenuka kwa photoelectric mu optical communications, ma modules optical amagwiritsidwa ntchito kwambiri m'malo opangira deta.Malo opangira deta achikhalidwe makamaka amagwiritsa ntchito 1G / 10G otsika optical modules, pamene malo osungiramo mitambo amagwiritsa ntchito ma modules a 40G / 100G othamanga kwambiri.Ndi mawonekedwe atsopano ogwiritsira ntchito monga mavidiyo otanthauzira kwambiri, kuwulutsa pompopompo, ndi VR ikuyendetsa kukula kwachangu kwa anthu pa intaneti padziko lonse lapansi, potengera zomwe zikuchitika m'tsogolomu, zofunikira zomwe zikubwera monga cloud computing, Iaa S services, ndi deta yaikulu imayika zofunikira kwambiri. pa data center internal data transmission , Zomwe zidzabereka ma modules optical ndi maulendo apamwamba opatsirana m'tsogolomu.
Nthawi zambiri, tikamasankha ma module a kuwala, timaganizira kwambiri zinthu monga mawonekedwe ogwiritsira ntchito, zomwe zimafunikira pakutumiza kwa data, mitundu ya mawonekedwe, ndi mtunda wotumizira optical (fiber mode, mphamvu yamagetsi yofunikira, kutalika kwapakati, mtundu wa laser) ndi zina.
