ʻO Ethernet kahi ʻenehana ʻenehana kūloko kūloko, kahi i hoʻohana nui ʻia no ka hoʻopili ʻana i nā ʻōnaehana pūnaewele lehulehu e hoʻokō ai i kahi pūnaewele wahi kūloko (LAN). Nui nā ʻano Ethernet ma ka mākeke, ʻo ia ka Ethernet wikiwiki a me Gigabit Ethernet ka mea maʻamau. Hāʻawi ʻo Fast Ethernet (FS) iā ʻoe i kahi hoʻohālikelike kikoʻī o ka Ethernet wikiwiki a me Gigabit Ethernet e ʻike ai i ka ʻokoʻa ma waena o nā mea ʻelua.
He aha ka Ethernet wikiwiki?
ʻO Fast Ethernet (FE) ka huaʻōlelo no Ethernet ma ka ʻupena kamepiula, e hāʻawi ana i ka helu hoʻololi o 100Mbps. ʻO ka IEEE 802.3u 100BASE-T Fast Ethernet maʻamau i hoʻolauna mua ʻia e ka IEEE i ka makahiki 1995, a ʻo ka wikiwiki o ka hoʻouna ʻana o ka Ethernet wikiwiki ma mua he 10Mbps. ʻO ka maʻamau ʻo Fast Ethernet ʻekolu mau ʻāpana: 100BASE-FX, 100BASE-TX, a me 100BASE-T4. Hōʻike ka 100 i ka wikiwiki o ka hoʻouna ʻana o 100Mbit/s. "BASE" 'o ia ho'i ka ho'ouna 'ana i ka band base; ʻO ka leka ma hope o ka pākuʻi e pili ana i ka mea hoʻouna e lawe ana i ka hōʻailona, ʻo "T" ke kū nei no ka hui wili (keleawe), ʻo "F" ke ʻano o ka fiber optical; ʻO ke ʻano hope loa (huakaʻi "X", helu "4", a me nā mea ʻē aʻe) e pili ana i ke ʻano code laina i hoʻohana ʻia. Hōʻike ka papa ma lalo i nā ʻano Ethernet wikiwiki maʻamau.
He aha ka Gigabit Ethernet?
Hoʻohālikelike ʻia me ka Ethernet wikiwiki, hiki i ka Gigabit Ethernet (GE) ke hāʻawi i ka helu hoʻololi o 1000Mbps ma kahi pūnaewele kamepiula. ʻO ka maʻamau Gigabit Ethernet (i ʻike ʻia ʻo ka IEEE 802.3ab standard) ua paʻi ʻia e IEEE ma 1999, he mau makahiki wale nō ma hope o ka hiki ʻana mai o ka maʻamau Fast Ethernet, akā ʻaʻole i hoʻohana nui ʻia a hiki i ka makahiki 2010. o IEEE 803.2 Ethernet a me ka CSMA/CD media access control method, hiki ke hana i ka hapalua duplex a me ka piha duplex mode. Loaʻa iā Gigabit Ethernet nā kaula like a me nā mea hana me Fast Ethernet, akā ʻoi aku ka maʻalahi a me ka waiwai. Me ka hoʻomau mau ʻana o Gigabit Ethernet, ua ʻike ʻia nā mana hou aʻe, e like me 40G Ethernet a me 100G Ethernet. Loaʻa i ka Gigabit Ethernet nā kūlana papa kino like ʻole, e like me 1000BASE-X, 1000BASE-T, a me 1000BASE-CX.
ʻO ka mea i lunaka ka hoʻolauna pōkole o Gigabit Ethernet a me ka Ethernet wikiwiki i lawe ʻia iā ʻoe e ShenzhenHDV Kiʻi uilaon ʻenehana LTD a me SShenzhenHDV Kiʻi uilaon ʻO Technology LTD kahi hui kūikawā i ka kamaʻilio optical e like me ka mea hana nui, ka hana ponoʻī o ka hui:ONU moʻo, moʻo module optical,OLT moʻo, moʻo transceiver he moʻo wela o nā huahana.

ʻO ka hapa nui o nā fiber optical a mākou e ʻike maʻamau ai he mau mea lele fiber optical, ʻo ia hoʻi, loaʻa i nā ʻaoʻao ʻelua nā mea hoʻohui, hiki ke hoʻokomo pololei ʻia a wehe ʻia me ka ʻole o ka hoʻohana ʻana i nā mea hana ʻē aʻe, ʻo ka mea i kapa ʻia ʻo ka mea hoʻohui e pili ana iā SC, FC, LC a me nā ʻano hoʻohālikelike ʻē aʻe. .
A he aha ke kumu, e like me ka manaʻo o ka inoa e hiki ke hoʻokomo ʻia a huki ʻia i waho o ke kumu, hana maʻamau me ka ceramic, ʻo ke kumu maʻamau i ka manawa like me ka mea hoʻohui, a i ʻole ka ʻōlelo ākea, ua like ke kumu me kahi mea hoʻohui. , he aha ka mea kiko'ī? E haʻi mālie wau iā ʻoe.
ʻO ke kumu i loko o ka pulupulu ʻole he lahilahi loa a maʻalahi loa e haki, no laila pono kekahi mea e pale iā ia. No ka waena o ka fiber, e hoʻonoho mākou i ka pale e uhi i ke kumu e pāʻani ai i kahi hana pale, a laila no ka huelo o ka fiber hoʻohana mākou i ka core ceramic. Aia kekahi puka liʻiliʻi loa i waenakonu o ke kumu, ua hou ʻia ke kumu i loko o kēia puka ma ka ʻāpana metala a laila ma waho o ka ʻāpana seramika, ʻoki ʻia ka ʻāpana ʻē aʻe mai ka ʻaoʻao seramika, a laila lawe i ka mea hana e wili ai. ʻO ka ʻāpana ʻē aʻe i palahalaha, a e makaʻala i ka wā e wili ai, ʻo ka nui o ka ikaika e uhaʻi i ke kumu i loko o ke kumu. (Hoʻomanaʻo ʻo Xibian ua hoʻopau ʻia ke kumu o loko e ka lima i ka wā o ka hoʻokolohua o ke kulanui. Ke hoʻouna ʻia ke kukui, ʻike ʻia ua hoʻopuka ke poʻo plug i kahi kukui ʻulaʻula maopopo, akā ʻaʻole kiʻekiʻe ka mana hoʻāʻo, no ka mea, ʻaʻole ke kukui. hoʻolaha ʻia ma kahi laina pololei, akā ua hoʻopuehu ʻia, e hopena i kahi kukui haʻahaʻa i ana ʻia ma ka helu ʻana ʻO ka hopena metala ka waena o ka fiber optical, i pale ʻia e ka pale a me ka uhi ʻana hui pū, ʻaʻole wale no ka pilina paʻa, akā no ka pale ʻana i ke kahe ʻana o ka māmā ʻOiaʻiʻo, ʻaʻole pili pono ka metala kumu i ka fiber optical, hiki ke hoʻohana ʻia no ka hana BOSA.
ShenzhenHDV Kiʻi uilaon ʻenehanaLTD. lawe mai iā ʻoe i ka wehewehe ʻana o ka "optical fiber plug", a ʻo kā mākou hui he mea hana ʻoihana kamaʻilio optical, ʻoi aku ka nui o nā huahana nui. ma mua oONU moʻo,OLT series, optical module series, transceiver series a pela aku. Loaʻa i nā mea hana ma luna aʻe nā ʻano kikoʻī a me nā hiʻohiʻona e hāʻawi i nā lawelawe i kuhikuhi ʻia no nā hiʻohiʻona noi pūnaewele like ʻole, e hoʻokipa i kou hōʻea ʻana.
