E like me ka hoʻokaʻawale ʻokoʻa o ka manawa hoʻomohala:
Hoʻokaʻawale ʻia nā modula Optical i ʻelua ʻano: PON optical modules a me nā modula optical maʻamau.
I ka hoʻohana ʻana i nā modula optical kuʻuna: ʻO ke ʻano o ka hoʻouna ʻana i ka hōʻailona optical he point-to-point (P2P: hoʻokahi hoʻouna i hoʻokahi), hoʻohana ʻia nā modula i ʻelua (e like me TX13RX15 a me TX15RX13), a hoʻohana i hoʻokahi fiber optical a i ʻole ʻelua mau fiber optical no ka hoʻoili (hiki ke hoʻokaʻawale ʻia i ke ʻano duplex a i ʻole simplex).
ʻO ka nalowale o ka pilina fiber Optical e pili ana i ka attenuation, dispersion, fiber connection insertion loss, etc. ʻO ka hoʻopuehu ʻana ma muli o ka hoʻonui ʻia ʻana o ka pulse ma muli o ka nui o ka hoʻouna ʻana o nā lōʻihi nalu optical. ʻO ka module kuʻuna he lōʻihi ka lōʻihi o ka laweʻana, a hiki i 200km; ma muli o ke kumu kūʻai, ʻaʻole ia i hoʻohana ʻia i ka pūnaewele hiki, a hoʻohana nui ʻia i ka ʻupena kuamoʻo.
I ka hoʻohana ʻana i nā modula optical PON, ʻo ke ʻano hoʻoili o nā hōʻailona optical he point-to-multipoint (P2MP: hiki ke hoʻouna i nā mea he nui ma o ODN), a ʻaʻole hoʻohana ʻia nā modula i ʻelua. ʻO ka nalowale o ka pilina fiber Optical e pili ana i ka attenuation, dispersion, frequency division ratio loss, optical fiber connect insertion loss, etc.; ʻoi aku ka pōkole o ka mamao o ka lawe ʻana ma mua o nā modula kuʻuna, a ʻo ka mamao he 20km wale nō; hoʻohana nui ʻia i nā ʻupena komo.
ʻO ka mea i luna nei ka wehewehe ʻana o ka ʻokoʻa ma waena o PON optical modules a me nā modula optical kuʻuna i lawe ʻia e Shenzhen HDV photoelectric Technology Co., Ltd. ʻO nā huahana module i hana ʻia e ka uhi ʻoihananā modules fiber optical, Nā modules Ethernet, nā modules transceiver fiber optical, nā modules komo fiber optical, SSFP mau modula optical, aʻO nā fiber optical SFP, etc. Hiki i nā huahana module i luna ke hāʻawi i ke kākoʻo no nā hiʻohiʻona pūnaewele like ʻole. Hiki i kahi hui R&D ʻoihana a ikaika ke kōkua i nā mea kūʻai aku me nā pilikia ʻenehana, a hiki i kahi hui ʻoihana noʻonoʻo a ʻoihana ke kōkua i nā mea kūʻai aku e loaʻa nā lawelawe kiʻekiʻe i ka wā o ka kūkākūkā mua a me ka hana ma hope o ka hana. Welina mai iā ʻoekāhea iā mā˚ouno kēlā me kēia ʻano nīnau.
