Mawu osakira: kuchuluka kwamphamvu kwa netiweki, luso laukadaulo lopitilirabe, mapulojekiti oyendetsa othamanga kwambiri ayambitsidwa pang'onopang'ono
M'nthawi ya mphamvu zamakompyuta, ndi kuyendetsa mwamphamvu kwa mautumiki ambiri atsopano ndi ntchito, matekinoloje opititsa patsogolo luso lamitundu yambiri monga kuchuluka kwa ma signal, kupezeka kwa spectral wide, multiplexing mode, ndi mauthenga atsopano otumizira akupitiriza kupanga zatsopano ndikukula.
Choyamba, kutengera mawonekedwe a mawonekedwe kapena kuchuluka kwa siginecha yamayendedwe, kukula kwa10G PONkutumizidwa mu netiweki yofikira kwakulitsidwanso, miyezo yaukadaulo ya 50G PON yakhazikika, ndipo mpikisano wamayankho aukadaulo a 100G/200G PON ndi wowopsa; maukonde opatsirana akulamulidwa ndi 100G/200G liwiro Kukula, gawo la 400G data center mkati kapena kunja mlingo interconnection akuyembekezeka kuwonjezeka kwambiri, pamene 800G/1.2T/1.6T ndi zina apamwamba mlingo chitukuko cha mankhwala ndi kafukufuku muyezo luso amalimbikitsidwa pamodzi. , ndi opanga mitu yolumikizirana yakunja yakunja akuyembekezeka kumasula 1.2T kapena kuchuluka kwapamwamba kogwirizana kwa DSP pokonza zida za chips kapena mapulani achitukuko.
Kachiwiri, potengera mawonekedwe amtundu womwe ulipo wotumizira, kukulitsa kwapang'onopang'ono kwa C-band yamalonda kupita ku C+L band kwakhala njira yolumikizira makampani. Zikuyembekezeka kuti ntchito yopatsira ma labotale ipitilirabe bwino chaka chino, ndipo nthawi yomweyo pitilizani kuchita kafukufuku pamitundu yambiri monga gulu la S + C + L.
Chachitatu, kuchokera pakuwona kwa ma signal multiplexing, teknoloji yogawanitsa malo idzagwiritsidwa ntchito ngati njira yothetsera vutoli kwa nthawi yayitali. Dongosolo la chingwe chapansi pamadzi chokhazikika pakuwonjezera pang'onopang'ono kuchuluka kwa ma optical fiber pairs apitiliza kutumizidwa ndikukulitsidwa. Kutengera ma mode multiplexing ndi/kapena angapo Ukadaulo wa core multiplexing udzapitilira kuphunziridwa mozama, kuyang'ana pakuwonjezera mtunda wopatsirana ndikuwongolera magwiridwe antchito.
Kenako, malinga ndi ma TV atsopano opatsirana, G.654E Ultra-low-Loss Optical fiber adzakhala chisankho choyamba pa thunthu maukonde ndi kulimbikitsa kutumizidwa, ndipo adzapitiriza kuphunzira kwa danga magawano multiplexing kuwala CHIKWANGWANI (chingwe). Sipekitiramu, kuchedwa kochepa, kutsika kopanda malire, kufalikira kochepa, ndi maubwino ena angapo akhala akuyang'ana kwambiri pamsika, pomwe kutayika kwa kufalitsa ndi kujambula kwakonzedwanso. Kuonjezera apo, pakuwona teknoloji ndi kutsimikizira kukhwima kwa mankhwala, chidwi cha chitukuko cha mafakitale, ndi zina zotero, ogwira ntchito zapakhomo akuyembekezeka kuyambitsa makina othamanga kwambiri monga DP-QPSK 400G mtunda wautali, 50G PON-mode-mode coexistence. ndi kuthekera kopatsirana kofananira mu 2023 Ntchito yotsimikizira mayeso imatsimikiziranso kukhwima kwa mawonekedwe othamanga kwambiri. zogulitsa ndikuyala maziko operekera malonda.
Pomaliza, ndi kusintha kwa kuchuluka kwa mawonekedwe a data ndi mphamvu yosinthira, kuphatikiza kwakukulu komanso kutsika kwamphamvu kwamphamvu kwakhala zofunikira zachitukuko cha gawo la optical unit of optical communication, makamaka muzochitika zogwiritsira ntchito data center, pamene mphamvu yosinthira ikufika 51.2 Tbit/s Ndipo pamwambapa, mawonekedwe ophatikizika a ma module opangidwa ndi 800Gbit/s ndi pamwamba angayang'anizane ndi mpikisano wokhazikika wa phukusi la pluggable ndi photoelectric. (CPO). Zikuyembekezeka kuti makampani monga Intel, Broadcom, ndi Ranovus apitiliza kusintha mkati mwa chaka chino Kuphatikiza pa zinthu zomwe zilipo ndi mayankho a CPO, ndipo atha kuyambitsa mitundu yatsopano yazinthu, makampani ena aukadaulo a silicon photonics nawonso azitsatira mwachangu kafukufuku ndi chitukuko. kapena tcherani khutu kwa izo.
Kuphatikiza apo, pankhani yaukadaulo wophatikizira mafoto kutengera mawonekedwe a module ya kuwala, silicon photonics idzakhala limodzi ndi ukadaulo wophatikizira wa III-V semiconductor, popeza ukadaulo wa silicon photonics uli ndi kuphatikiza kwakukulu, kuthamanga kwambiri, komanso kuyanjana bwino ndi njira zomwe zilipo za CMOS ntchito pang'onopang'ono mu sing'anga ndi mtunda waufupi pluggable kuwala ma modules, ndipo wakhala woyamba kufufuza njira kwa CPO kuphatikiza. Makampaniwa ali ndi chiyembekezo chokhudza chitukuko chamtsogolo chaukadaulo wa silicon photonics, ndipo kuwunika kwa ntchito yake mu computing ya optical ndi magawo ena kudzachitikanso.
