Iterambere ryitumanaho rya optique itumanaho: 5G imiyoboro, 25G / 100G modul optique niyo nzira
Mu ntangiriro za 2000, imiyoboro ya 2G na 2.5G yarimo kubakwa, kandi guhuza sitasiyo fatizo byatangiye guca mu nsinga z'umuringa kugera ku nsinga za optique.Ubwa mbere, 1.25G SFP optique modules yarakoreshejwe, hanyuma hakoreshwa modul ya 2.5G SFP.
Kubaka umuyoboro wa 3G byatangiye muri 2008-2009, kandi ibyifuzo bya sitasiyo ya optique modules byasimbutse kuri 6G.
Muri 2011, isi yinjiye mukubaka imiyoboro ya 4G, hamwe na moderi nyamukuru ya 10G optique ikoreshwa muri prequel.
Nyuma ya 2017, yagiye ihinduka buhoro buhoro imiyoboro ya 5G hanyuma isimbukira kuri 25G / 100G optique.Umuyoboro wa 4.5G (ZTE bita Pre5G) ukoresha modul optique imwe na 5G.
Kugereranya imiyoboro ya 5G yububiko hamwe na 4G yubatswe: Mugihe cya 5G, ongera igice cyohereza, biteganijwe ko ibyifuzo bya optique bizamuka
Umuyoboro wa 4G uva RRU ujya kuri BBU kugeza mucyumba cya mudasobwa.Mugihe cyurusobe rwa 5G, imikorere ya BBU irashobora kugabanywa no kugabanywa DU na CU.Umwimerere RRU kuri BBU ni iyimbere, naho BBU mubyumba bya mudasobwa yibanze ni iyinyuma.Kuva hanze.
Uburyo BBU igabanijwe bifite ingaruka zikomeye kuri module optique.Mubihe bya 3G, abacuruza ibikoresho byo murugo bafite ibyo batandukanije nibihugu mpuzamahanga.Mugihe cya 4G, baringaniye nibihugu byamahanga, kandi 5G itangiye kuyobora.Vuba aha, Verizon na AT & T batangaje ko bazatangira ubucuruzi 5G mumyaka 19, umwaka umwe mbere yUbushinwa.Mbere yibyo, inganda zizeraga ko abatanga isoko nyamukuru bazaba Nokia Ericsson, hanyuma Verizon igahitamo Samsung.Igenamigambi rusange ryubwubatsi bwa 5G mubushinwa rirakomeye, kandi nibyiza guhanura bimwe.Muri iki gihe, yibanda cyane ku isoko ry’Ubushinwa.
5G imbere yohereza amatara module: 100G igiciro kiri hejuru, kuri ubu 25G niyo nzira nyamukuru
Byombi imbere ya 25G na 100G bizabana.Imigaragarire hagati ya BBU na RRU mugihe cya 4G ni CPRI.Kugirango wuzuze umurongo mwinshi wa 5G, 3GPP itanga icyerekezo gishya cya eCPRI.Niba interineti ya eCPRI ikoreshwa, umurongo mugari wibisabwa byimbere yimbere bizagabanywa kugeza kuri 25G, bityo bigabanye ibiciro bya Transmission optique. Birumvikana ko gukoresha 25G nabyo bizazana ibibazo byinshi.Birakenewe kwimura ibikorwa bimwe na bimwe bya BBU muri AAU kugirango ubone ibimenyetso byo gutoranya no kwikuramo.Nkigisubizo, AAU iba iremereye kandi nini.AAU imanikwa ku munara, ifite amafaranga menshi yo kubungabunga hamwe n’ingaruka zo hejuru.Inganda nini, abakora ibikoresho bagiye bakora kugirango bagabanye AAU no kugabanya gukoresha amashanyarazi, bityo bakaba batekereza no gukemura 100G kugirango bagabanye umutwaro wa AAU.Niba ibiciro bya 100G optique bishobora kugabanuka neza, abakora ibikoresho bazakomeza gushaka ibisubizo 100G.
5G Hagati: Amahitamo meza ya module nibisabwa biratandukanye cyane
Abakozi batandukanye bafite uburyo butandukanye bwo guhuza.Munsi y'urusobe rutandukanye, guhitamo numubare wa optique modules bizatandukana cyane.Abakiriya bashyize imbere 50G ibisabwa, kandi tuzitabira byimazeyo ibyo abakiriya bakeneye.
5G Gusubira inyuma: Moderi ihuriweho neza
Inyuma izakoresha moderi ya optique hamwe na interineti yagutse irenga 100G.Bigereranijwe ko konti 200G ihwanye na 2/3 na 400G ihwanye na 1/3.Kuva imbere kugeza hagati kunyura inyuma yinyuma, ihuza intambwe kumurongo.Ingano ya optique module ikoreshwa kuri pass inyuma ni ntoya kurenza iyanyuze hejuru, ariko igiciro cyibiciro kiri hejuru.
Ejo hazaza: hashobora kuba isi ya chip
Ibyiza bya chip bizatuma birushaho kuba ngombwa muri module.Kurugero, MACOM iherutse gushyira ahagaragara inganda ya mbere ihuriweho na monolithic chip ya intera ngufi ya 100G optique, insinga za optique (AOC) hamwe na moteri ya optique.Ohereza kandi wakire ibisubizo.MALD-37845 nshyashya ihuza imiyoboro ine yohereza no kwakira amakuru yo kugarura amasaha (CDR), ibyuma bine byongera imbaraga (TIA), hamwe na bine ya vertical cavity surface isohora laser (VSCEL) kugirango itange abakiriya Ubworoherane budasanzwe bwo gukoresha kandi buke cyane igiciro.
MALD-37845 nshya ishyigikira igipimo cyuzuye cyamakuru kuva 24.3 kugeza 28.1 Gbps kandi yagenewe CPRI, 100G Ethernet, 32G Fibre Fibre, hamwe na 100G EDR itagira imipaka.Bizaha abakiriya imbaraga nkeya-imwe ya chip igisubizo kandi ni optique optique Ideal kubigize.MALD-37845 ishyigikira imikoranire hamwe na lazeri zitandukanye za VCSEL hamwe na fotodetekeri, kandi software yayo irahuza nibisubizo bya MACOM mbere.
Marek Tlalka, umuyobozi mukuru ushinzwe kwamamaza mu ishami ry’ibicuruzwa bigereranywa n’ibicuruzwa muri MACOM, yagize ati: "Optical module na AOC batanga igitutu kinini kuko bakeneye gufasha abakiriya kugera ku ntera nini ya 100G."Ati: "Turizera ko MALD-37845 ishobora gutsinda ihuzwa ry’ibibazo ndetse n’ibiciro bikomoka ku bicuruzwa gakondo bikoresha chip nyinshi kandi bigatanga ibisubizo by’indashyikirwa mu bikorwa bigufi 100G."
MACOM's MALD-37845 100G igisubizo kimwe-chip ubu kirimo gutoranya abakiriya kandi biteganijwe ko kizatangira kubyazwa umusaruro mugice cya mbere cya 2019.
