    Ka ʻike kumu e pili ana i ka module optical GPON

    Ka manawa hoʻouna: Iulai-26-2022

    I kēia mau lā, me ka hoʻomau mau ʻana a me ka hoʻomaikaʻi ʻana i nā modula fiber optical, ua lilo ʻo PON (passive optical fiber network) i ala koʻikoʻi e lawe i nā lawelawe ʻoihana ākea ākea. Ua māhele ʻia ʻo PON i GPONaEPON. Hiki ke ʻōlelo ʻia ʻo GPON he mana hou o EPON. ʻO kēia ʻatikala, etu-link, e alakaʻi iā ʻoe e hoʻomaopopo i ka module optical GPON.

    Ka ʻike kumu e pili ana i ka module optical GPON, ka ʻike kumu e pili ana i ka GPON SFP Transceivers, He aha ka module GPON, He aha ka GPON a pehea e hana ai, sfp gpon module

    ʻO ka mea mua, ʻoi aku ka maikaʻi o ka ʻenehana GPON ma mua o ka EPON ma ke ʻano o ka hoʻohana ʻana i ka bandwidth, ke kumukūʻai, ke kākoʻo lawelawe lehulehu, nā hana OAM a me nā mea ʻē aʻe. Hoʻohana ʻo GPON i ka code scrambling e like me ke code line, hoʻololi wale i ke code me ka hoʻonui ʻole i ke code, no laila ʻaʻohe poho o ka bandwidth. Ma keʻano o ke kumukūʻai hoʻokahi, haʻahaʻa ke kumukūʻai me ka wikiwiki wikiwiki o Gigabit. Ma muli o kāna ʻano hoʻopihapiha kū hoʻokahi, hiki iā ia ke kākoʻo maikaʻi i nā lawelawe ATM a me nā lawelawe IP. He waiwai nui ka OAM i ka ʻike, e like me ka hoʻokaʻawale ʻana i ka bandwidth, ka hoʻokaʻawale ʻana i ka bandwidth (DBA), ka nānā ʻana i ka loulou, ka hoʻololi ʻana i ka pale, ka hoʻololi kī, a me nā hana hoʻāla like ʻole.

    Hoʻokaʻawale ʻia ka GPON system optical module i ʻekolu mau pae: A, B, a me C. He ʻokoʻa nā mea hōʻailona optical o kēlā me kēia pae. I kēia manawa, ua māhele nui ʻia i nā papa b+ a me c+. ʻO ka laulā mana loaʻa o kaONUʻO ka ʻaoʻao ma kahi o 1-2dBm ka liʻiliʻi ma mua o kaOLTʻaoʻao. ʻO nā ʻokoʻa penei:

    Ka ʻike kumu e pili ana i ka module optical GPON, ka ʻike kumu e pili ana i ka GPON SFP Transceivers, He aha ka module GPON, He aha ka GPON a pehea e hana ai, sfp gpon module

    ʻO ka hana nui o kaGPON ONU  ʻO ka module optical e loaʻa a hoʻokuʻu i ka mālamalama, i ʻike ʻia e ka laser, e hoʻololi i ka hōʻailona uila modulated i kahi hōʻailona optical a hoʻokomo i loko o ka ʻoihana fiber optical no ka lawe ʻana. Loaʻa i ka mea hoʻokipa ke kukui, hoʻonui i ke kukui i loaʻa a hoʻololi iā ia i hōʻailona uila i ka ʻōnaehana no ka hana hōʻailona e loaʻa ai ka ʻike pono. hiki i 20km. ʻO 1310nm ka lōʻihi o ka hawewe a ʻo 1490nm ka lōʻihi o ka hawewe. Kākoʻo ʻia ka hana hōʻoia kikohoʻe DDM, a ʻo ka mahana hana o ka papa pāʻoihana (0 °C - 70 °C) a me ka papa hana ʻenehana (-40 °C - +85 °C) he koho.

    ʻO ka GPON OLT Hoʻopili ʻia ka module optical me SFP, SC interface, 2.5g / 1.25g transmission rate, 20km transmission distance, 1490nm transmission wavelength, 1310nm loaʻa ka nalu, a me ke kākoʻo no ka DDM digital diagnostic function, e kūpono ia no nā laina laina optical.

     

    ʻO ka mea i luna nei ka wehewehe ʻike o GPON optical module i lawe ʻia e Shenzhen HDV photoelectric Technology Co., 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, 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 ʻoe kāhea iā mā˚ou no kēlā me kēia ʻano nīnau.
