He aha ke ʻano o ka ʻōnaehana o ka Optical Access Network (OAN) Optical access network (OAN) e pili ana i ka hoʻohana ʻana i ka fiber optical ma ke ʻano he mea hoʻouna nui e ʻike ai i ka hana hoʻoili ʻike o ka pūnaewele hiki. Hoʻopili ʻia ia i ka node lawelawe ma o ka laina optical te...

Me ka hoʻomau mau ʻana o ke kūkulu ʻana i ka ʻoihana pūnaewele kiʻekiʻe a me ka pono e kūkulu i kahi ola akamai kikohoʻe e pili ana i ka hiki ʻana o ka pūnaewele "ʻekolu gigabit", pono nā mea hoʻohana i nā mamao hoʻouna lōʻihi, nā bandwidth kiʻekiʻe, ʻoi aku ka hilinaʻi a me nā lilo o ka ʻoihana haʻahaʻa ...

Hoʻohana ka pūnaewele EPON i ke ʻano FTTB e hana i kahi pūnaewele, a ʻo kāna mau ʻāpana pūnaewele kumu ʻo OLT a me ONU. Hāʻawi ka OLT i nā awa PON nui no nā lako keʻena kikowaena e hoʻopili ai i nā lako ONU; ʻO ONU ka mea hoʻohana e hāʻawi i ka ʻikepili kūpono a me nā leo leo e ʻike ai i ka lawelawe mea hoʻohana ...

ONU (hui pūnaewele ʻike) node ʻike. Hoʻokaʻawale ʻia ʻo ONU i loko o ka ʻenehana optical optical a me ka hale waihona puke passive optical network unit. ʻO ka mea maʻamau, ua kapa ʻia nā mea lako me ka nānā ʻana o ka pūnaewele me ka mea hoʻokipa optical, uplink optical transmitter a me nā mea hoʻonui alahaka lehulehu i kapa ʻia ʻo optical node....

Me ka hoʻomohala ʻana o ka ʻenehana kikohoʻe, ka ʻenehana kamaʻilio optical a me ka ʻenehana polokalamu a me ka hoʻohana ākea o ka protocol TCP / IP, ka ʻoihana kelepona, ka ʻenehana kamepiula a me ka ʻoihana televise e hui pū kekahi me kekahi a lilo i hui ma lalo o IP hiki ke hāʻawi i ka leo, da...

FTTH Fiber Circuit Classification Ua māhele ʻia ka papa hoʻouna o FTTH i ʻekolu mau ʻāpana: Duplex (dual fiber bidirectional) loop, Simplex (single fiber bidirectional) loop a me Triplex (single fiber three-way). ma waena o ka hopena OLT a me ka ON...
