Kuenzanisa kweshanu PON-yakavakirwa FTTX kuwana

Iyo yazvino yakakwirira-bandwidth yekuwana networking nzira inonyanya kuenderana nePON-yakavakirwa FTTX kuwana. Iwo makuru maficha uye fungidziro inosanganisirwa mumutengo wekuongorora ndeaya anotevera:

● Mutengo wezvishandiso zvechikamu chekuwana (kusanganisira dzakasiyana siyana dzekuwana michina uye mitsara, nezvimwewo, yakaverengerwa kune yega yega mushandisi)

● Mari yekuvaka yehuinjiniya (inosanganisira mari yekuvaka nemimwe mari yekuwedzera, kazhinji 30% yemutengo wemidziyo yese)

● Kushanda uye kugadzirisa mari (kazhinji inenge 8% yemari yose pagore)

● Muyero wekuisa hautariswe (ndiko kuti, chiyero chekuisa i100%).

● Mari yemidziyo inodiwa inoverengerwa zvichienderana ne500 mushandisi mhando

Cherechedza 1: FTTX kuwana haifungi mutengo wekamuri yekombuta yenharaunda;

Cherechedzo 2: ADSL2+ haina pundutso kana ichienzaniswa neADSL kana chinhambwe chekusvika chiri 3km. VDSL2 parizvino haisati yashandiswa zvakanyanya, saka hapana kuenzanisa kuchaitwa panguva iripo;

Cherechedzo 3: Optical fiber yekuwana ine mabhenefiti ari pachena pamadaro marefu.

FTTB+LAN

Iyo yepakati hofisi inofambiswa kuburikidza neoptical fiber (3km) kune aggregationchinjayenzvimbo yekugara kana chivakwa, uyezve yakabatana nemukoridhochinjakuburikidza neoptical fiber (0.95km), uye yozoendeswa kumagumo emushandisi uchishandisa Chikamu 5 tambo (0.05km). Yakaverengerwa zvinoenderana ne500 mushandisi modhi (pasina kutarisisa mutengo wekamuri yesero), ingangoita imwe 24-port aggregation.chinjauye 21 24-port corridorswitcheszvinodiwa. Mukushandiswa chaiko, imwe nhanho yekuwedzera yechinjainowanzowedzerwa. Kunyange zvazvo nhamba yose yeswitchesinowedzera, kushandiswa kwemhando dzakaderera-yemutengo wekoridhoswitchesinoderedza mutengo wakakwana.

FTTH

Funga kuisa anOLTpahofisi yepakati, imwe optical fiber (4km) kune sero yepakati komputa mukamuri, musero repakati komputa mukamuri kuburikidza ne1: 4 optical splitter (0.8km) kumukoto, uye 1: 8 optical splitter (0.2km ) mukoridho yemushandisi terminal. Yakaverengerwa zvinoenderana ne500-mushandisi modhi (pasina kufunga mutengo wekamuri yesero): Mutengo weOLTmidziyo yakagoverwa pachiyero chevashandisi ve500, inoda huwandu hwegumi nematanhatuOLTports.

FTTC+EPON+LAN

Uyezve funga kuisa iyoOLTpahofisi huru. Imwe optical fiber (4km) inotumirwa kukamuri yepakati komputa yenharaunda. Iyo yepakati komputa kamuri yenharaunda ichapfuura nepakati pe1: 4 Optical splitter (0.8km) kuenda kuchivakwa. Mukoridho yega yega, 1: 8 optical splitter (0.2km) ichashandiswa. ) Enda kune imwe neimwe pasi, uye wozobatanidza kune mushandisi terminal neChikamu 5 mitsetse. Mumwe nomumweONUine Layer 2 switching function. Tichifunga kutiONUine 16 FE ports, kureva imwe neimweONUinogona kuwana vashandisi ve16, iyo inoverengerwa zvinoenderana ne500 mushandisi modhi.

FTTC+EPON+ADSL/ADSL2+

Kune imwecheteyo application yeDSLAM yakadzika shift, funga kuisa anOLTkuhofisi yepakati, uye imwe faibha (5km) kubva kuBAS yekupedzisira hofisi kuenda kune general end office, uye pa general end office, inopfuura nepa1:8 optical splitter (4km) kuendaONUmuchitokisi pakati komputa. TheONUyakabatana zvakananga neDSLAM kuburikidza neFE interface, uyezve yakabatana kune yekupedzisira mushandisi neyakamonyoroka peya (1km) tambo yemhangura. Inoverengerwawo zvichienderana ne500 mushandisi modhi yakabatana kune yega yega DSLAM (pasina kufunga mutengo wekamuri yesero).

Point-to-point optical Ethernet

Iyo yepakati hofisi inoiswa kuburikidza neoptical fiber (4km) kune aggregationchinjayenharaunda kana chivakwa, uye yobva yaiswa zvakananga kumushandisi kumagumo kuburikidza neoptical fiber (1km). Yakaverengerwa zvinoenderana ne500 mushandisi modhi (pasina kutarisisa mutengo wekamuri yesero), ingangoita 21 24-port aggregation.switcheszvinodikanwa, uye 21 mapeya e4 makiromita emusana optical fibers akaiswa kubva pakati pehofisi komputa mukamuri kuenda kuunganidzwa.switchesmuchitokisi. Sezvo point-to-point optical Ethernet isingawanzo kushandiswa kuwana Broadband munzvimbo dzekugara, inowanzo shandiswa chete kune network yevashandisi vakakosha vakapararira. Naizvozvo, dhipatimendi rayo rekuvaka rakasiyana nedzimwe nzira dzekuwana, saka nzira dzekuverenga dzakasiyana zvakare.

Kubva pakuongorora kwepamusoro, zvinogona kuonekwa kuti kuiswa kwe-optical splitter kuchava nemigumisiro yakananga pakushandiswa kwefiber, iyo inokanganisawo mari yekuvaka network; mutengo wazvino weEPON wemidziyo unonyanya kudzikiswa neiyo burst optical transmit/receive module uye iyo core control module/ Chips uye E-PON module mitengo inogara ichidzikiswa kuti isangane nemusika zvinodiwa; kana ichienzaniswa nexDSL, mutengo wePON wenguva imwe chete wakakwirisa, uye parizvino uri kunyanya kushandiswa munzvimbo dzichangovakwa kana kuvakwa patsva. Point-to-point optical Ethernet inokodzera chete hurumende yakapararira uye vatengi vemabhizinesi nekuda kwekudhura kwayo. Kushandisa FTTC+E-PON+LAN kana FTTC+EPON+DSL ndiyo mhinduro iri nani yekuchinja zvishoma nezvishoma kuenda kuFTTH.
