FTTH. Tekinoroji
Kutanga, chii chinonzi FTTH?
Wakambonzwa nezve FTTH?
Kana imba fiber optic tekinoroji
Zvakafanana neDSL here kana padyo nechizvarwa chechina 4G
, Ehe, kune izvi kana izvo, mumitsara iri kuuya isu tichapindura iyi mibvunzo nerunako uye zvakadzama.
FTTH (fiber kumba):
Kana imba fiber optics itekinoroji yekufambisa dhata neruzivo mukati megirazi tambo kumhanya kwakanyanya zvakaenzana nekumhanya kwechiedza, zvichireva kuti iwe unogona kufungidzira isingaverengeke uye isingaverengeke huwandu hwedata uye ruzivo kuyerera.Mumasekondi mashoma, kuwedzera pakuisa mafaera mahombe egigabyte saizi mumasekondi, achitamba online pasina kukanganiswa, kutora chikamu kuburikidza nevhidhiyo yako yekubatanidza, uye kutarisa IPTV pamusoro peInternet.
FTTH Optical Fiber:
Nzira dzakanakisa, dzichangoburwa uye dzakagadzikana nzira dzekutaurirana dziripo parizvino kuti dzibatanidze neInternet, kuwedzera kune yayo yakanaka kumhanya.Iyo tekinoroji yakagadzikana isingakanganiswe nezvinhu zvekunze sekukanganisa, mhepo, kupisa kwekunze, uye zvimwe.
Musiyano muzvinyorwa.
FTTN .. Fiber kuNode.
Viber kusvika padanho rekuunganidza.
FTTC .. Fibre kune iyo Curb.
Fiber kune nzira yemugwagwa.
FTTB .. Fiber kuChivakwa.
Viber kumusoro kwechivako.
FTTH .. Fiber kuMusha.
Viber kumusoro kweimba.
Iyo FTTH zvinoreva kuti iyo fiber inosvika panogara mushandisi, nepo FTTB inomiririra iyo fiber kuwana chete kune ichi chivakwa uye kwete imba kana pekugara. FTTC uye FTTN zvakare zvinoreva kuti iyo fiber inosvika isingasvike mazana matatu emamita kwekutanga uye anopfuura mazana matatu emamiriyoni kwechipiri, uku kusiana kuri, chokwadika, kunoratidzwa muhunhu uye nekukurumidza kwekubatana.
Network zvikamu uye nemabatiro avanoshanda:
Iyo michina iri muganisi kana matumba inonzi:
(OLT: Optical Line Kubvisa).
Uye ine makadhi akati wandei, kadhi rega rega rine akati wandei emachiteshi anonzi:
(PON: Passive Optical Network).
Iyo yakabatana kune imwechete yeinternet filament iyo inopfuudza uye inogashira panguva mbiri dzakasiyana wavelengths. Kusvikira kumatanho makumi matanhatu nemasere anoshandirwa pachiteshi chimwe nechimwe nekuparadzanisa iyo filament mune mafirita neanopatsanura uye iyo filamendi yakabatana pane iyo terminal:
(ONT: Optical Network Kubvisa).
Dhawunirodha (Dhawunirodha reData):
Paunenge uchishandisa iyo GPON protocol, iyo yakazara yakasanganiswa kumhanya ndeye 2.488 gigabits pakureba kwe1490 nm. Mhedzisiro dzese dzinogashira ma sign ese uye dzinongogamuchira ruzivo rwunotariswa kuchinhu chinogamuchira. Iyo yekumhanyisa kumhanya inotsigirwa kune imwechete terminal ndeye 100Mbps.
Dharira Dhata:
Iyo yakasanganiswa yakazara kumhanya ndeye 1.244 gigabits uchishandisa iyo wavelength ye1310 nm. Chidimbu chega chega chinogumira chinotumira masaini ayo panguva yakatarwa uye inogara ichichinja nguva dzechiteshi, uchifunga nezvezvinokosha, nhanho yemhando, kumhanyisa kwakabvumiranwa, uye huwandu hwekusangana.
Dhawunirodha (Dhawunirodha Vhidhiyo):
Iyo wavelength ye1550 nm inoshandiswa kutepfenyura vhidhiyo. Iyo yekumhanyisa kumhanya inotsigirwa kune imwechete terminal kifaa ndeye 100Mbps.
Ivhareji yekumhanyisa yaunoda iwe kumba kwako:
Kana iwe uri kubvunza nezve yakakodzera FTTH kumhanya kweimba yako, avhareji yekumhanyisa iyo imba inoda kusvika 40 MB, kuti ubatsirwe nemapurogiramu ehurukuro yevhidhiyo, mitambo, tarisa maTV epamberi, uye kurodha mafaera nguva dzose uye nekuenderera.
Zvinyorwa zveFTTH:
Zvinoenderana nezvirongwa zvakaita se:
1- GPON.
2-EPON.
3-BPON.
Uye ichangoshandiswa ndiyo giga .. GPON
(GPON: Gigabit Passive Optical Network).
Ruzivo rwacho rwunotakurwa pamapakeji anonzi .. GEM
(GEM: GPON Encapsulation Module).
Izvo zvakanakira FTTH network uye kuenzanisa kwayo nekopasi network DSL:
1- Kumhanya kwazvo.
2- Kururama uye kuchena kwezviratidzo.
3- Iko kumhanya hakudzikire nekuwedzera chinhambwe. Mutengi ari kure anogona kuwana iyo kumhanya kumwechete nemutengi ari padyo.
4- Kugadzikana kwemasevhisi uye nyore kwekuvapa.
5- Kukwanisa kwayo kutsigira masevhisi emangwana.
6- Kukwanisa kushandura kugona uye huwandu hwemachiteshi kumutengi nekushandura chishandiso.
7- Chinhambwe chinopfuura makiromita masere uye kusvika pamakumi matanhatu emakiromita muchiitiko chekuti tsika haina kubatanidzwa.
Icho chikonzero chekufamba kunononoka kwetekinoroji yeFTTH:
Uku kunonoka kuri kukonzerwa nenyaya yekuti michina yeiyi tekinoroji inodhura kwazvo, kuwedzera kune kunetsekana kwekuchengetedza pamwe nekuisa faibha dzemaziso kana zvakuvara. Asi chipingamupinyi chikuru kunetsekana kwekugadzirisa zvivakwa zviripo nezvivakwa zvinodiwa pahunyanzvi uhu, pamusoro pekuti mushandisi wepakati haadi kumhanya kwakanyanya. Izvi zvikonzero zviviri zvinoita kuti hukama hwetsika newaya yemhangura huenderere nanhasi.
Tinokuda iwe, vateveri vedu vanokosheswa, mune hutano hwakanaka uye hutano
