Munguva pfupi yapfuura, China Academy of Telecommunication Research, pamwe chete neZTE Corporation Limited neChangfei Optical Fiber and Cable Co., LTD. (inozivikanwawo se "Changfei Company") yakavakirwa pafiber ye quartz yemhando imwe chete, yakapedza kuyedza kweS+C+L multi-band large-capacity transmission, chiyero chepamusoro che single-wave chakasvika 1.2Tbit/s, uye chiyero che single-direction transmission che single-direction.faibhayakadarika 120Tbit/s. Isa rekodhi itsva yepasi rose yehuwandu hwekutumira kwefiber yakajairika ye single-mode panguva chaiyo, zvakaenzana nekutsigira kutumirwa kwemazana emafirimu e4K high-definition kana data rekudzidzisa mamodheru eAI akawanda pasekondi.
Mishumo inoti, bvunzo yekusimbisa ye single-fiber unidirectional super 120Tbit/s yakawana mhedzisiro yakanaka muhupamhi hwesystem spectrum, ma key algorithms uye dhizaini yezvivakwa.
Panyaya yehupamhi hwema "system spectrum", zvichibva pa "C-band" yechinyakare, hupamhi hwema "system spectrum" hunowedzerwawo kuma "S" ne "L bands" kuti uwane bandwidth yakakura kwazvo yekutaurirana yeS+C+L multi-band kusvika ku17THz, uye huwandu hwe "band" hunofukidza 1483nm-1627nm.
Panyaya yemaalgorithms akakosha, China Academy of Telecommunication Research inosanganisa hunhu hweS/C/L three-band optical fiber loss uye power transfer, uye inopa chirongwa chekuwedzera kushanda zvakanaka kwespectrum kuburikidza ne adaptive matching ye symbol rate, channel interval uye modulation code type. Panguva imwe chete, nerubatsiro rweZTE's multi-band system filling wave uye automatic power balancing technology, mashandiro e channel-level service akaenzana uye daro rekutumira rinowedzerwa.
Panyaya yekugadzira mapurani, transmission iyi inoshandisa tekinoroji yepamusoro ye photoelectric sealing tekinoroji, chiyero che single-wave signal baud chinodarika 130GBd, chiyero che bit chinosvika 1.2Tbit/s, uye huwandu hwezvinhu zve photoelectric hunochengetwa zvakanyanya.
Kuedza uku kunoshandisa kuderedzwa kwakanyanya uye fiber ye optical yenzvimbo yakakura yakagadzirwa neChangfei Company, iyo ine kuderedzwa kwakanyanya uye nzvimbo yakakura inoshanda, zvichibatsira kuona kuwedzera kwehupamhi hwe spectral system kuS-band, uye mwero wepamusoro we single wave panguva chaiyo unosvika 1.2Tbit/s.faibha yemazisoyakaona kuti dhizaini, kugadzirira, maitiro, zvinhu zvakagadzirwa uye zvimwe zvinongedzo zvirimo.
Tekinoroji yehungwaru hwekugadzira uye mashandisirwo ayo ebhizinesi ari kukura, zvichikonzera kuwedzera kwekuda kwebandwidth yekubatanidza nzvimbo dzedata. Senzira yekubatanidza data yekugadzirwa kweruzivo rwedhijitari, network ye-optical inofanirwa kupfuurira kuburikidza nekumhanya uye kugona kwekutumira optical. Ichitevedzera chinangwa che "smart connection kuti pave nehupenyu huri nani", kambani ichabatana nevashandi nevatengi kuti vatarise pakutsvaga nekuvandudza matekinoroji makuru ekukurukurirana kwe optical, kuita kushandira pamwe kwakadzama uye kutsvaga kutengeserana muminda yemitengo mitsva, mabhendi matsva, uye fiber itsva dze optical, uye kuvaka hunyanzvi hutsva hwemabhizinesi ane tekinoroji itsva, kugara vachikurudzira kukura kwakasimba kwenetwork ye-optical, uye kubatsira kuvaka hwaro hwakasimba hweramangwana redhijitari.
