Hoʻohana ʻia ka hapa nui o nā modules optical i loko o ka ʻupena kuamoʻo o ka ʻoihana fiber optical, a ʻo ka transceiver optical he mea pono ia e hoʻolōʻihi i ke kaula pūnaewele. He aha ka ʻokoʻa ma waena o nā modula optical a me nā transceivers optical? 1. ʻO nā modula Optical nā mea hana, hoʻohana wale ʻia i ...

E like me nā lālā nui ʻelua o ka ʻike pūnaewele optical, EPON a me GPON kēlā me kēia me ko lākou pono ponoʻī, hoʻokūkū kekahi i kekahi, hoʻokō kekahi i kekahi, a aʻo mai kekahi i kekahi. E hoohalikeia lakou ma na ano like ole. Hāʻawi ka Rate EPON i ka uplink paʻa a me ka downlink 1.25 Gbps, hoʻohana i ka laina 8b/10b ...

1.1 ʻO ka mea hoʻokaʻawale ʻo Passive kahi mea koʻikoʻi o ka pūnaewele PON. ʻO ka hana o ka passive optical splitter ʻo ia ka hoʻokaʻawale ʻana i ka mana optical o hoʻokahi hōʻailona optical hoʻokomo i nā huahana he nui. ʻO ka maʻamau, loaʻa ka splitter i ka hoʻokaʻawale māmā mai 1: 2 a 1: 32 a i ʻole ...

Hoʻohālikelike o ʻelima PON-based FTTX loaʻa ʻO ke ʻano o ka hoʻohana pūnaewele kiʻekiʻe-bandwidth i kēia manawa ua hoʻokumu nui ʻia ma ka PON-based FTTX access. ʻO nā hiʻohiʻona nui a me nā manaʻo e pili ana i ka nānā ʻana i ke kumukūʻai penei: ● ʻO ke kumu kūʻai o nā lako o ka ʻāpana komo (me nā ʻano mea komo a me nā laina ...

He aha ka GPON? ʻO ka ʻenehana GPON (Gigabit-Capable PON) ka hanauna hou loa o ka broadband passive optical integrated access standard ma muli o ke kūlana ITU-TG.984.x. He nui kona mau pono e like me ka bandwidth kiʻekiʻe, ka hana kiʻekiʻe, ka uhi nui, a me nā mea hoʻohana waiwai. Manaʻo ka hapa nui o nā mea hoʻohana ...

Nui nā kukui hōʻailona ma ka modem fiber optic, a hiki iā mākou ke hoʻoholo inā he hewa nā mea hana a me ka pūnaewele ma o ke kukui kuhikuhi. Eia kekahi mau hōʻailona modem optical maʻamau a me ko lākou mau manaʻo, e ʻoluʻolu e ʻike i ka wehewehe kikoʻī ma lalo nei. 1. I mea e maʻalahi ai ka wahi ...
