2.1.Transmission chiteshi zvinodiwa:
2.1.1.Kufambiswa kwe14 * 10 Gigabit masevhisi kubva mukamuri komputa yemuguta kuenda kukamuri yekombuta yeNanhai
2.1.2, basa guru renzira, chinja chekuchengetedza nzira≤32mms
2.1.3.Iyo OTU yemuno inogona kushandiswa kugadzira chiratidzo, kukudza, uye kubvisa wachi.
2.2.Transmission chiteshi zvinodiwa:
2.2.1.Kutumirwa kwe14 * 10 Gigabit masevhisi kubva mukamuri yekombuta yedhorobha kuenda kukamuri yekombuta yeShunde
2.2.2, iyo huru nzira yebasa, iyo backup nzira switch ≤ 32mms
2.3.3.Iyo OTU yemuno inogona kushandiswa kugadzira chiratidzo, kukudza, uye kubvisa wachi.
2.3.Transmission chiteshi zvinodiwa:
2.3.1.8*10 Gigabit masevhisi anofambiswa kubva mukamuri yemukombuta yeguta kuenda kuGaoming komputa kamuri
2.3.2.Nzira huru inoshanda uye imwe nzira yekuchinja ndeye ≤32mms
2.3.3.Iyo OTU yemuno inogona kushandiswa kugadzira chiratidzo, kukudza, uye kubvisa wachi.
3.1.Tsanangudzo yechirongwa
3.1.1.Tichifunga nezvekuwedzera kwesimba, iyo wave demultiplexing unit yakagadzirirwa zvinoenderana ne8 mafungu
3.1.2.Kuverengerwa kweiyo data yakapihwa yekudzikisira tambo yemaziso (kurasikirwa kwekubatanidza uye kurasikirwa kwekuisa kunosanganisirwa).
3.1.3.Batanidza optical simba kuverenga:
Unidirectional: Iyo imwechete-wave inopenya simba reiyo optical module inoverengerwa pa0dBm (-2～3dBm), yakakwidziridzwa neBA uye yakaderedzwa neOLP, iyo inouya fiber optical simba ndeye +4dBm, yakaderedzwa nemutsara 27dBm, OLP 2dB yakaderedzwa, uye simba rinopinda muPA riri -25dBm , Mushure mePA 20dB kukwidziridzwa, simba rimwechete-wave riri -5dBm, mushure meDEMUX de-wave, simba re-single-wave riri -10dBm, rinovimbiswa kuva mukati mekunzwa kwehuwandu hwe Optical module;
Reverse: Mushure mekuverenga, simba re-single-wave pamagumo ekugamuchira ndeye -10dBm, iyo inovimbiswa kuva mukati mehutano hwekunzwa kweiyo optical module.
3.1.4.System OSNR calculation (nyore): OSNR=58+4-27-1-6=28dB≥24dB, iyo inosangana nemaitiro ekugadzira.
3.2.Solution zvakanakira
3.2.1.Shandisa DWDM kune multiplex 40 masevhisi pane imwe optical tambo yekutapurirana, iyo inochengetedza zvakanyanya optical cable zviwanikwa paunenge uine bandwidth;
3.2.2.Kugadzikana kwepamusoro: Iyi sarudzo yekugadzira inotora OLP 1 + 1 mbiri mbiri nzira yekudzivirira, inotsigira otomatiki switching, uye inovimbisa kugadzikana kwebhizinesi;
3.2.3.WDM midziyo inotora modular dhizaini, inopatsanura inoshanda uye isingaiti, iri nyore kuwedzera, inongoda kuwedzera bhodhi rebasa kana uchiwedzera, pasina kukanganisa bhizinesi riripo.
3.2.4.Bhodhi reOTU rinotora dhizaini ye3R, inogona kugadziridza chiratidzo, kukwidziridza wachi uye kugadzirisa nguva kuti ive nechokwadi chekuti chiratidzo hachina kukanganisa.
3.2.5.Tsigira masevhisi akasiyana kuti uwane SDH, PDH, CATV, Ethernet, izwi data, nezvimwewo, inoenderana nemidziyo kubva kune vakasiyana vagadziri.
3.2.6.Chishandiso chinopa 1 + 1 inopisa yekuchengetedza magetsi, iyo inovandudza kugadzikana kwechigadzirwa
3.2.7.Iva ane simba manejimendi manejimendi mabasa, ayo anogona kuona kure kure network manejimendi, ziva online chaiyo-nguva yekutarisa bhizinesi, uye kufambisa kugadzirisa.
