Kupfuura 120Tbit/s! Telecom, ZTE neChangfei vakabatana vakaseta rekodhi yenyika itsva yenguva chaiyo yekutapurirana mwero weyakajairwa single-mode optical fiber.

Munguva pfupi yapfuura, China Academy yeTelecommunication Research, pamwe neZTE Corporation Limited uye Changfei Optical Fiber uye Cable Co., LTD. (inozonzi "Changfei Kambani") zvichibva pane yakajairwa-mode quartz fiber, yakapedzwa S+C+L yakawanda-bhendi yakakura-yekugona kutapurirana kuyedza, iyo yepamusoro chaiyo-nguva imwechete-wave mwero yakasvika 1.2Tbit/s, uye mwero wekufambiswa kwegwara rimwe chetefiberkupfuura 120Tbit/s. Seta rekodhi yenyika itsva yeiyo chaiyo-nguva yekufambisa mwero yeyakajairwa single-modhi faibha, yakaenzana nekutsigira kutapurirana kwemazana e4K epamusoro-tsanangudzo mafirimu kana akati wandei AI modhi yekudzidzisa pasekondi.

Sekureva kwemishumo, bvunzo yekusimbisa yeiyo single-fiber unidirectional super 120Tbit/s yakawana mhedzisiro mhedzisiro muhurongwa hwehupamhi hwehupamhi, kiyi algorithms uye dhizaini yekuvaka.

Panyaya yeiyo system spectrum hupamhi, zvichibva pane yechinyakare C-bhendi, iyo system spectrum hupamhi inowedzerwa kune S uye L mabhendi kuti iwane yakakura-huru yekutaurirana bandwidth yeS + C + L yakawanda-bhendi kusvika ku17THz, uye bhendi renji rinovhara 1483nm-1627nm.

Panyaya yeakakosha algorithms, iyo China Academy yeTelecommunication Tsvagiridzo inosanganisa hunhu hweS/C/L matatu-bhendi optical fiber kurasikirwa uye kufambisa simba, uye inopa zano rekuwedzera spectrum kunyatsoshanda kuburikidza neadaptive inofananidzwa yechiratidzo chiyero, chiteshi kupindirana uye modulation. rudzi rwekodhi. Panguva imwecheteyo, nerubatsiro rweZTE's akawanda-bhendi system yekuzadza wave uye otomatiki magetsi ekuyera tekinoroji, iyo chiteshi-chikamu sevhisi kuita kwakaenzana uye kureba kwekufambisa kunokwidziridzwa.

Panyaya yedhizaini yezvivakwa, iyo chaiyo-nguva yekufambisa inotora iyo indasitiri yemhando yepamusoro yekuisa chisimbiso tekinoroji, iyo single-wave chiratidzo baud rate inodarika 130GBd, iyo bit rate inosvika 1.2Tbit/s, uye nhamba yezvikamu zvephotoelectric inoponeswa zvakanyanya.

Kuedza kunotora iyo yekupedzisira-yakaderera attenuation uye yakakura inoshanda nzvimbo optical fiber yakagadziriswa neChangfei Kambani, iyo ine yakaderera attenuation coefficient uye yakakura inoshanda nzvimbo, ichibatsira kuona iyo system spectral hupamhi hwekuwedzera kune S-bhendi, uye yepamusoro-soro chaiyo- nguva imwe chete wave rate inosvika 1.2Tbit/s. Theoptical fiberyaona kugadzikwa kwedhizaini, kugadzirira, maitiro, zvigadzirwa uye zvimwe zvinongedzo.

Artificial intelligence tekinoroji uye mashandisiro ayo ebhizinesi ari kuwedzera, zvichiunza kuputika mukudiwa kwedata center interconnection bandwidth. Seiyo bandwidth yekona yedhijitari ruzivo ruzivo, ese-optical network inoda kupfuurira kutyora chiyero uye kugona kwekutapurirana kwemaziso. Kuomerera kune chinangwa che "smart connection yehupenyu huri nani", kambani ichabatana nemaoko nevashandisi uye vatengi kuti vatarise kutsvagisa uye kuvandudzwa kweiyo yakakosha tekinoroji yekutaurirana kwemaziso, kuita kudyidzana kwakadzama uye kuongorora kwekutengesa muminda. yemitengo mitsva, mabhendi matsva, uye itsva optical fibers, uye kuvaka hutsva hwemhando yezvigadzirwa zvemabhizinesi nehunyanzvi hwekuvandudza tekinoroji, inogara ichisimudzira kusimudzira kwakasimba kweiyo-yese-optical network, uye kubatsira kuvaka hwaro hwakasimba hweramangwana redhijitari.
