Aloha e ka poʻe heluhelu, Ma lalo iho nei mākou e kamaʻilio e pili ana i ka Classification of PON Modules a e hoʻāʻo e wehewehe maʻalahi iā ʻoe.
(1)OLTmodule optical aONUkōpili ʻōpika: E like me ka hoʻokaʻawale ʻokoʻa o nā polokalamu plug-in aia ʻelua ʻano o nā modula optical PON:OLTmodule optical (ua hoʻokomo nui ʻia kēia module i loko o kaOLTpau, a hiki ole ke kaana aku me kaONUmodule optical) aONU(Hoʻokomo nui ʻia kēia module i loko o ka ʻāpana pūnaewele optical) module optical. pūʻolo SFP.
Nānā:OLTʻoi aku ka paʻakikī o nā modules optical ma mua oONUnā modules optical, no ka mea, kēlā me kēiaOLTpono e hiki i ka module optical ke hoʻouna i nā hōʻailona me ka nui o 64ONUnā modules optical.
(2) ʻO ka ʻokoʻa ma waena o GPON optical module, EPON optical module a me APON optical module.E like me ka hoʻokaʻawale ʻokoʻa o nā kūlana ʻenehana (ʻo ia hoʻi nā protocol transmission),Hiki ke hoʻokaʻawale ʻia nā modules optical PON i ʻehā mau ʻano: ʻo APON ka ATM PON, ʻo BPON ka broadband passive optical network, ʻo EPON ka Ethernet passive optical network a ʻo GPON ka gigabit passive optical network. ʻano EPON a me GPON.
Loaʻa nā modula optical EPON i nā pūʻolo SFP, XFP a me SFP +, me kahi mamao o ka lawe ʻana a hiki i 20km, a ʻo ka ʻāpana hoʻokipa he preamplifier i hoʻopaʻa ʻia a me kahi mea hoʻonui palena me ka LVPECL kūpono like ʻole.
ʻO ka module optical GPON kahi module optical kiʻekiʻe a me ka hoʻokele waiwai no nā noi kelepona ʻike optical serial o 2.5Gpbs (hiki i ka downlink ke hiki i ka helu kiʻekiʻe). ʻO ka pōmaikaʻi o kēia module optical ʻo ia ka mea hiki ke hōʻoiaʻiʻo ʻaʻole pōʻino maka i kekahi pōʻino hewa.
ʻO ka mea i luna nei ka wehewehe wehewehe ʻana o nā modules PON i lawe ʻia e Shenzhen HDV photoelectric Technology Company Ltd., ʻO nā huahana module i hana ʻia e ka uhi ʻoihana.nā 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. modules, etc. Hiki i nā huahana module i luna ke hāʻawi i ke kākoʻo no nā hiʻohiʻona pūnaewele like ʻole. No nā huahana i luna, hiki i kahi hui R&D loea a ikaika ke hāʻawi i ke kākoʻo ʻenehana no nā mea kūʻai aku, a hiki i kahi hui ʻoihana noʻonoʻo a ʻoihana ke hāʻawi i nā lawelawe kiʻekiʻe no nā mea kūʻai aku i ka kūkākūkā mua a me ka hana ma hope. Welina mai iā ʻoekāhea iā mā˚ouno kēlā me kēia ʻano nīnau.
