Kuvandudzwa kwewireless optical communication modules: 5G network, 25G / 100G optical modules ndiwo maitiro.
Mukutanga kwe2000, 2G uye 2.5G network yaive ichivakwa, uye base station yekubatanidza yakatanga kucheka kubva patambo dzemhangura kuenda kune optical cables.Pakutanga, 1.25G SFP optical modules yakashandiswa, uye ipapo 2.5G SFP modules yakashandiswa.
3G network yekuvaka yakatanga muna 2008-2009, uye kudiwa kwe base station optical modules kwakasvetukira ku6G.
Muna 2011, nyika yakapinda mukuvakwa kwe4G network, uye iyo huru 10G optical modules inoshandiswa mu prequel.
Mushure me2017, yakashanduka zvishoma nezvishoma kune 5G network uye yakasvetukira ku25G / 100G optical modules.Iyo 4.5G network (ZTE inodaidza Pre5G) inoshandisa yakafanana optical modules se5G.
Kuenzanisa kwe5G network architecture uye 4G network architecture: Munguva ye5G, wedzera chikamu chekutumira, zvinotarisirwa kuti kudiwa kwema modules optical kuchamuka.
Iyo 4G network inobva kuRRU kuenda kuBBU kune yakakosha komputa kamuri.Munguva ye5G network, iyo BBU mabasa anogona kupatsanurwa uye akakamurwa kuita DU neCU.Iyo yekutanga RRU kuBBU ndeyekumberi, uye iyo BBU yepakati komputa kamuri ndeye backhaul.Kunze kwekupfuura.
Iyo BBU yakakamurwa sei ine mhedzisiro yakakura pane optical module.Munguva ye3G, vatengesi vemidziyo yemumba vane mamwe mapeji ane ekunze.Munguva ye4G, ivo vari pamwe chete nenyika dzekunze, uye nguva ye5G inotanga kutungamirira.Munguva pfupi yapfuura, Verizon uye AT & T vakazivisa kuti vachatanga kushambadzira 5G mumakore gumi nemapfumbamwe, gore rimwe chete pamberi peChina.Izvi zvisati zvaitika, indasitiri yaitenda kuti mutengesi wepamusoro aizova Nokia Ericsson, uye pakupedzisira Verizon yakasarudza Samsung.Kuronga kwese kwe5G kuvaka muChina kwakasimba, uye zviri nani kufanotaura zvimwe.Nhasi, inonyanya kutarisa pamusika weChina.
5G kumberi kwechiedza chekufambisa module: 100G mutengo wakakwirira, ikozvino 25G ndiyo inonyanya kukosha
Zvose zviri zviviri fronthaul 25G uye 100G zvichagara pamwe chete.Iyo interface pakati peBBU neRRU munguva ye4G ndeye CPRI.Kuti usangane nepamusoro bandwidth zvinodiwa zve5G, 3GPP inokurudzira hutsva hunoenderana nechiyero eCPRI.Kana iyo eCPRI interface inoshandiswa, iyo bandwidth inodiwa ye fronthaul interface ichamanikidzwa ku25G, nokudaro kuderedza optical Transmission cost.Zvechokwadi, kushandiswa kwe25G kuchaunzawo matambudziko akawanda.Izvo zvinodikanwa kufambisa mamwe mabasa eBBU kuenda kuAAU yechiratidzo sampling uye compression.Nekuda kweizvozvo, AAU inorema uye yakakura.AAU yakaturikwa pashongwe, iyo ine mutengo wepamusoro wekugadzirisa uye njodzi dzemhando yepamusoro.Yakakura, vagadziri vezvigadzirwa vave vachishanda kuderedza AAU uye kuderedza kushandiswa kwesimba, saka vari kufungawo 100G mhinduro kuderedza mutoro weAAU.Kana 100G optical module mitengo inogona kuderedzwa zvinobudirira, vagadziri vemidziyo vacharamba vaine 100G mhinduro.
5G Yepakati: Optical module sarudzo uye huwandu hunodiwa zvinosiyana zvakanyanya
Vashandisi vakasiyana vane nzira dzakasiyana dzemambure.Pasi pekubatana kwakasiyana, kusarudzwa uye nhamba ye optical modules ichasiyana zvakanyanya.Vatengi vakaisa mberi 50G zvinodiwa, uye isu tichashingaira kupindura kune zvinodiwa nevatengi.
5G Backhaul: Coherent Optical Module
Iyo backhaul ichashandisa coherent optical modules ine interface bandwidths inodarika 100G.Inofungidzirwa kuti 200G inowirirana maakaunti ye2/3 uye 400G inowirirana maakaundi ye1/3.Kubva kumberi kuenda pakati kuenda kuback pass, inopindirana nhanho nhanho.Huwandu hwemamodule optical anoshandiswa kupass back idiki pane iyo yekupfuura pass, asi mutengo weyuniti wakakwira.
Ramangwana: inogona kunge iri nyika yemachipisi
Izvo zvakanakira zvakanakira chip zvinozoita kuti zviwedzere kukosha mune module.Semuenzaniso, MACOM nguva pfupi yadarika yakatanga indasitiri yekutanga yakabatanidzwa monolithic chip yepfupi-renji 100G optical transceivers, inoshanda tambo dzemaziso (AOC) uye on-board optical injini.Tumira uye ugamuchire mhinduro.Iyo itsva MALD-37845 inobatanidza zvisina mutsetse yechina-channel kutumira uye kugamuchira wachi data kudzoreredza (CDR) mabasa, ina transimpedance amplifiers (TIA), uye ina vertical cavity surface emitting laser (VSCEL) madhiraivha kuti ape vatengi nyore kusingaenzaniswi kwekushandisa uye kuderera zvakanyanya. mutengo.
Iyo itsva MALD-37845 inotsigira zvizere data data kubva ku24.3 kusvika ku28.1 Gbps uye yakagadzirirwa CPRI, 100G Ethernet, 32G Fiber Channel, uye 100G EDR unlimited bandwidth applications.Ichapa vatengi vane yakaderera-simba single-chip mhinduro uye iri compact optical Ideal yezvikamu.MALD-37845 inotsigira kudyidzana neakasiyana VCSEL lasers uye mafotodetectors, uye firmware yayo inoenderana neyakare MACOM mhinduro.
"Optical module uye vapeji veAOC vari pasi pekumanikidzwa kukuru nekuti vanoda kubatsira vatengi kuwana hukuru hukuru hwekubatanidza 100G," akadaro Marek Tlalka, mukuru wekushambadzira director wepamusoro-inoshanda analog zvigadzirwa chikamu paMACOM."Isu tinotenda kuti MALD-37845 inogona kukunda kubatanidzwa uye kudhura matambudziko ari muzvigadzirwa zvechinyakare zvakawanda-chip uye kupa mhinduro dzepamusoro-soro dzemapfupi-renji 100G maapplication."
MACOM's MALD-37845 100G single-chip mhinduro ikozvino yave sampling kune vatengi uye yakarongerwa kutanga kugadzirwa muhafu yekutanga ye2019.
