ʻO ka PON optical module, i kekahi manawa i kapa ʻia ʻo ka module PON, he ʻōnaehana optical kiʻekiʻe i hoʻohana ʻia i nā ʻōnaehana PON (passive optical network).Hoʻohana ia i nā lōʻihi nalu like ʻole e hoʻouna a loaʻa i nā hōʻailona ma waenaOLT(Optical Line Terminal) aONT(Optical Network Terminal) e like me ka ITU-T G.984.2 standard and multi-source agreement (MSA).ʻO ke kūlana ʻoihana o kēia manawa: downlink (OLT-ONU) e hoʻouna i ka nalu o 1490nm;uplink (ONU-OLT) e hoʻouna i ka nalu o 1310nm.
ʻAʻole hiki ke hoʻokaʻawale ʻia ka noi ākea o ka PON Ethernet passive optical network mai ka PON optical module no ka mea he mea nui ia o ka ʻōnaehana PON.Hoʻololi nui ka module PON i ka hōʻailona uila o ka OLT i kahi hōʻailona optical modulated a hoʻouna iā ia i ka ONU, aʻo ka uplink e hoʻololi i ka hōʻailona optical modulated e kaONUi loko o kahi hōʻailona uila a hoʻouna i kaOLT.Hoʻomaopopo ʻia ke ala hoʻoili fiber optical ma waena o ka OLT a me ka ONU.
Ka helu ʻana o nā modula PON: I kēia manawa, ua māhele ʻia nā modula PON i hoʻohana ʻia i ka ʻoihana i ʻelua mau ʻano maʻamau:
GPON-Gigabit Passive Optical Network
EPON-Ethernet Passive Optical Network
Inā ʻaʻole kumu ke kumu kūʻai, ʻoi aku ka maikaʻi o ke koho mua ʻana i ka pūnaewele GPON no ka mea ʻoi aku ka nui o nā lawelawe a me ka hana ʻoi aku ka maikaʻi.
ʻO ka mea i luna nei he wehewehe o ka ʻike module PON 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.
