2.1.Zvinodiwa zvechiteshi chekutumira:
2.1.1. Kutumirwa kwemasevhisi e14*10 Gigabit kubva mukamuri remakombiyuta reguta kuenda kukamuri remakombiyuta reNanhai
2.1.2, basa guru renzira, chinja chenzira yekuchengetedza≤32mm
2.1.3. OTU yemuno inogona kushandiswa kugadzira chiratidzo, kuwedzera, uye kubvisa wachi.
2.2. Zvinodiwa panzira yekutumira:
2.2.1. Kutamiswa kwemasevhisi e14*10 Gigabit kubva mukamuri remakombiyuta reguta kuenda kukamuri remakombiyuta reShunde
2.2.2, basa guru renzira, chinja chenzira yekuchengetedza ≤ 32mms
2.3.3. OTU yemuno inogona kushandiswa kugadzira chiratidzo, kuwedzera, uye kubvisa wachi.
2.3. Zvinodiwa panzira yekutumira:
2.3.1. Masevhisi e8*10 Gigabit anotumirwa kubva mukamuri remakombiyuta reguta kuenda kukamuri remakombiyuta reGaoming
2.3.2. Nzira huru inoshanda uye switch yeimwe nzira ndeye ≤32mms
2.3.3. OTU yemuno inogona kushandiswa kugadzira chiratidzo, kuwedzera, uye kubvisa wachi.
3.1. Tsananguro yechirongwa
3.1.1. Tichifunga nezvekuwedzera kwesimba, chikamu chekubvisa mafungu chakagadzirwa zvichienderana nemafungu masere
3.1.2. Kuverengwa kwedata rakapihwa rekudzikamisa tambo ye optical (kurasikirwa kwekubatana uye kurasikirwa kwekuisa zvinosanganisirwa).
3.1.3. Kuverenga simba re optical link:
Kunongedzera: Simba rinopenya remafungu rimwe chete remodule ye optical rinoverengerwa pa 0dBm (-2 ～ 3dBm), rinowedzerwa neBA uye rinoderedzwa neOLP, simba re optical re fiber rinouya riri + 4dBm, rinoderedzwa nemutsara we 27dBm, OLP 2dB inoderedzwa, uye simba rinopinda muPA riri -25dBm, Mushure mekuwedzera kwePA 20dB, simba remafungu rimwe chete riri -5dBm, mushure meDEMUX de-wave, simba remafungu rimwe chete riri -10dBm, iro rinovimbiswa kuti riri mukati mehuwandu hwe sensitivity yemodule ye optical;
Kudzokera shure: Mushure mekuverenga, simba remafungu rimwe chete pamugumo wekugamuchira i -10dBm, iyo inovimbiswa kuti iri mukati mehuwandu hwekunzwisisa kwe optical module.
3.1.4. Kuverenga kweSystem OSNR (zviri nyore): OSNR=58+4-27-1-6=28dB≥24dB, iyo inosangana nezvinodiwa zvekugadzira.
3.2. Zvakanakira mhinduro
3.2.1. Shandisa DWDM kusanganisa masevhisi makumi mana patambo imwe chete ye optical yekutumira, izvo zvinochengetedza zvakanyanya zviwanikwa zvetambo ye optical uku uchivimbisa bandwidth;
3.2.2. Kugadzikana kwakanyanya: Dhizaini iyi yemhinduro inoshandisa OLP 1+1 dual way protection, inotsigira otomatiki switching, uye inovimbisa kugadzikana kwebhizinesi;
3.2.3. Midziyo yeWDM inoshandisa dhizaini yemodular, inoparadzanisa inoshanda uye isingashande, iri nyore kuwedzera, inongoda kuwedzera bhodhi rebasa kana ichikura, pasina kukanganisa bhizinesi riripo.
3.2.4. Bhodhi reOTU rinoshandisa dhizaini ye3R, iyo inogona kuumba patsva chiratidzo, kuwedzera wachi uye kugadzirisa nguva kuti ive nechokwadi chekuti chiratidzo hachina kukanganiswa
3.2.5. Tsigira masevhisi akasiyana kuti uwane SDH, PDH, CATV, Ethernet, voice data, nezvimwewo, zvinoenderana nemidziyo kubva kuvagadziri vakasiyana
3.2.6. Mudziyo uyu unopa simba rekuchengetedza rinopisa re1+1, izvo zvinoita kuti mudziyo ugare wakasimba
3.2.7. Iine mabasa ane simba ekutarisira network, ayo anogona kuita kuti network itongwe iri kure, kuita kuti bhizinesi ritariswe online panguva chaiyo, uye kuita kuti kugadziriswa kuitwe.
