ʻO ka PON optical module he mea hana kiʻekiʻe o ka optical module i hoʻohana ʻia i ka ʻōnaehana PON (passive optical network), i ʻike ʻia ʻo PON module, ma ka laina me ka ITU-T G.984.2 maʻamau a me ka protocol multi-source (MSA). Hoʻohana ʻo ia i nā lōʻihi hawewe like ʻole e hoʻouna a loaʻa i nā hōʻailona ma waena o ka OLT (optic line terminal) a me ka ONT (optical network terminal) (hoʻouna ʻia kēia hōʻailona e nā nalu māmā). ʻO ke kūlanaʻoihana o kēia manawa: Downlink (OLT - ONU) i hoʻounaʻia ma 1490nm wavelength; Hoʻouna ʻia i luna (ONU - OLT) ma kahi hawewe o 1310nm.
ʻAʻole hiki ke hoʻokaʻawale ʻia ka noi ākea o PON Ethernet passive optical network mai ka PON optical module, no ka mea he mea nui ia o ka ʻōnaehana PON. PON module nui hoohuliOLThōʻailona uila i loko o ka hōʻailona optical modulated e hoʻouna iONU; Hoʻouna ʻia ka uplink iOLTma ka hoohuli ana i ka hoailona optical modulated eONUi hōʻailona uila. ʻO ke ala lawe fiber optical ma waenaOLTaONUʻike ʻia.
Ka hoʻokaʻawale ʻana o nā modules PON: I kēia manawa, ʻelua ʻano o nā modula PON i hoʻohana mau ʻia i ka ʻoihana i māhele ʻia i:
GPON - Gigabit passive optical network
EPON - Ethernet passive optical network
Ināʻaʻoleʻoe e noʻonoʻo i ke kumu kūʻai, ua'ōleloʻiaʻoe e koho i ka pūnaewele GPON e hāʻawi i nā lawelawe piha a me ka hana maikaʻi.
ʻO ka mea ma luna nei ka wehewehe ʻike module PON i lawe ʻia e Shenzhen HDV Phoeletron Technology LTD. ʻO nā huahana modula i hanaʻia e ka hui e uhi i ka module fiber optical, Ethernet module, optical transceiver module, optical fiber access module, SSFP optical module, SFP optical fiber module a pēlā aku. Hiki i nā huahana papa o luna ke hāʻawi i ke kākoʻo no nā hiʻohiʻona pūnaewele like ʻole. No nā huahana i luna, ua hui pū ʻia me kahi hui R & D ʻoihana a ikaika e hāʻawi i ke kākoʻo ʻenehana no nā mea kūʻai aku, a me kahi hui ʻoihana noʻonoʻo a me ka ʻoihana e hāʻawi i ka lawelawe maikaʻi no nā mea kūʻai aku i ka kūkākūkā mua a me ka hana ma hope.
