Nekuvandudza tekinoroji yedhijitari, tekinoroji yekutaurirana uye tekinoroji yesoftware uye kushandiswa kwakakura kweTCP/IP protocol, telecommunication network, komputa network uye terevhizheni network zvichabatana pamwe chete uye kubatanidzwa pasi peIP inokwanisa kupa izwi, data nemifananidzo pa. panguva imwe chete Broadband multimedia kutaurirana network yebhizinesi. Ikozvino yemhangura yewaya yekuwana, isina waya, uye nzira dzekuwana LAN hazvisi nyore kuzadzisa chinangwa ichi, asi zviri nyore kune FTTH.

FTTH haingopi chete bandwidth yakakura, asi zvakare inosimudzira kujeka kwetiweki kune mafomati edatha, mareti, wavelengths uye maprotocol, inodzoreredza zvinodikanwa zvezvakatipoteredza uye magetsi, inorerutsa kuchengetedza nekuisa, uye inokwanisa kufambisa TDM, IP data. uye vhidhiyo panguva imwe chete Kugona kwemasevhisi ekutepfenyura, umo TDM neIP data inofambiswa muchimiro cheIEEE802.3 Ethernet, inowedzerwa neanotakura-giredhi network manejimendi system, inokwana kuve nechokwadi chekutapurirana kwemhando, uye kutepfenyura kwevhidhiyo kunogona kuitika. uchishandisa yechitatu wavelength (kazhinji 1550nm) Bhizinesi kutapurirana.

Iyo optical fiber access tekinoroji ndiyo mhinduro inoshandisa yese kana chikamu chefiber yefiber mu network yekuwana kuti iite optical fiber subscriber loop (FITL), kana optical fiber access network (OAN), kuti iwane Broadband access.

Maererano nenzvimbo yeONU, iyo fiber yekuwana network yakakamurwa kuita faibha kudesktop (FTTD), faibha kuenda kumba (FTTH), faibha kuenda kunzira (FTTC), faibha kuchivakwa (FTTB), faibha kuhofisi (FTTO), faibha kusvika pasi (FTTF), faibha kuchitokisi (FTTZ) nemamwe marudzi. Pakati pavo, FTTH ichave iyo yekupedzisira fomu yeramangwana Broadband yekuwana network yekuvandudza. FTTH inoreva kuiswa kwe optical network units (ONUs) pakugara kana vashandisi vemakambani. Iri imhando ye optical access network iri padyo nevashandisi muFTTx series kunze kweFTTD.

Zvinhu zvinofanirwa kutariswa mukuvandudzwa kweFTTH

Kunyangwe hazvo FTTH yakakura uye ichigoneka, uye mutengo wemutengo uri kuramba uchidonha, pachine matambudziko mazhinji ekuona kushandiswa kwakakura kweFTTH munyika yangu.

Cost issue

Parizvino, inopfuura 97% yeFTTH yekuwana network munyika inongopa masevhisi eInternet, nekuti mutengo wekupa nhare dzechinyakare neFTTH wakakwira zvakanyanya kupfuura mutengo weiyo iripo yakatarwa tekinoroji, uye kushandiswa kwefiber optical kutumira. nhare dzechinyakare dzakagadziriswa dzinewo dambudziko remagetsi efoni. Nhasi, iyo copper wire network ichiri nechinzvimbo chikuru.kushandiswa kwehunyanzvi hweADSL kunoita kuti kuvakwa kweprojekiti kuve nyore, kwakachipa, uye kunokwanisa kuzadzisa zvinodiwa zvebhizinesi razvino. Ndiyo mukwikwidzi mukuru weFTTH panguva ino.

Policy zvinhu

Pachine zvipingamupinyi zveindasitiri mukutsvaga kuwana FTTH yakazara sevhisi munyika yangu, kureva kuti, vafambisi venhare havatenderwe kushandisa masevhisi eCATV, pane zvinopesana, vashandisi veCATV havabvumidzwe kushandisa zvechinyakare telecom masevhisi (senge runhare), uye mamiriro aya haagone kuchinjwa kwenguva yakareba mune ramangwana Naizvozvo, mushandisi mumwe chete haagone kupa masevhisi ekutamba katatu pane network yeFTTH.

ONUkugarisana uye kudyidzana

Kugarisana kweONUinoita basa rakasimba mukusimudzira nekuvandudza kwese FTTH indasitiri cheni. FTTH chiyero chekushandisa uye kukwidziridzwa kuchiri kuda kuvandudza indasitiri zviyero nekukurumidza sezvinobvira. Vagadziri vezvishandiso vanofanirwa kushanda pamwe nemasangano ekumisikidza, vashandisi, vagadziri vemidziyo uye madhipatimendi ekugadzira kuti vatarise pazvinhu zvitanhatu zvinosanganisira system tekinoroji zviyero, FTTH mudziyo tekinoroji zviyero, FTTH optical tambo tekinoroji zviyero, FTTH engineering inotsigira tekinoroji zviyero, FTTH engineering kuvaka zviyero uye FTTH bvunzo. mipimo. Kune rimwe divi, gadzira zvizere FTTH indasitiri tekinoroji zviyero uye zvakatemwa kutungamira FTTH zvikumbiro.

Yakananga bhizimusi volume

Kushaikwa kwekushandisa chinhu chakakosha chinokanganisa kuenderera mberi kweFTTH. Kana iwe ukangosefa paInternet, 1M yekumhanyisa ADSL inokwana. Nekudaro, kana kudiwa kwemasevhisi kuchinge kwawedzera, senge dhijitari TV, VOD, Broadband vhidhiyo masevhisi, uye emhando yepamusoro mavhidhiyo emafoni, kutenga online, online mabasa ekurapa, nezvimwewo, iyo 1M bandwidth haizonyatso kutsigira, uye DSL. hazvizokwanisi kudaro. , FTTH ine nzvimbo yayo. Naizvozvo, kuvandudzwa kwemasevhisi ebroadband isimba rakakosha rekusimudzira FTTH.

Hunhu hwekushandisa kwenharembozha masevhisi munyika yangu kazhinji hwakaderera. Parizvino, kune vashoma vatengesi veFTTH vashandisi (vanenge zero), uye kukwidziridzwa kweFTTH kuchiri muhudiki. Nechikonzero ichi, kusarudza tekinoroji yeFTTH inoenderana nemamiriro enyika yedu kwakakosha kusimudzira kufarirwa kweFTTH munyika yedu. Nekuwedzera kwechiyero chekushandisa, mutengo weFTTH wemidziyo une nzvimbo huru yekudzikisa. Mune ramangwana, musika webroadband uchagarisana neADSL, FTTB + LAN, uye FTTH mukati meimwe nguva yenguva. ADSL icharamba iri iyo huru munguva pfupi. DSL uye FTTH ichakura pamwe chete. Kana mutengo weFTTH wemidziyo uchideredzwa zvishoma nezvishoma kusvika kuDSL nekuda kwekuwedzera kwehuwandu hwekuvaka Iyo FTTH musika wekutengesa uchawedzera zvakanyanya kana iyo nhanho yakakwira.
