No nā ʻenehana pūnaewele, ʻaʻole paha he malihiniSFPawa, mākou pinepine i loko o ke kuapo, optical module, router, media converter network lako i ike i ke ola o ia mea, akā, aia nō kekahi mau mea hoʻohana 'aʻole maopopo leʻa i kaSFPawa, a waiho i mua i kekahi mau pilikia, e like me, he aha ka hoʻohana oSFPawa,
ʻO kaSFPawa he awa fiber optical, hikiSFPport turn RJ 45, etc. E kālele ana kēia pepa i ka pane ʻana i kekahi mau nīnau i hopohopo nui ʻia e nā mea hoʻohana.
He aha kaSFPawa?ʻO kahi puka fiber?He aha ka hana o?
SFPʻO ke awa kahi kikowaena e hoʻokō ai i ka hoʻololi ʻana i ka hōʻailona photoelectric gigabit, ʻo kāna hana nui no ka hoʻololi ʻana i ka hōʻailona a me ka lawe ʻana i ka ʻikepili, ʻo kona mau awa e kū i nā kūlana IEEE 802.3ab (e like me 1000 BASE-T), ka nui o ka hoʻouna ʻana a hiki i 1000 Mbps (kekahi hoʻololi.SFPKākoʻo nā awa i ka 100 / 1000Mbps adaptive), no laila ua kapa ʻia ʻo ia ka gigabit fiber port.
He aha nā pōmaikaʻi o kaSFPnā awa?ʻO wai nā pūnaewele pūnaewele i hoʻohana mauʻia?
SFPAia ke awa i ka hot-plug I / O interface (e pili ana i ka input / output interface), me ka maʻalahi ikaika, kūpono no nā ʻenehana pūnaewele like ʻole, e like meSFPmodule optical, Gigabit switch, etc., hiki ke hoʻololi me 1000 BASE-SX, 1000 BASE-LX / LH, 1000 BASE-ZX a i ʻole 1000 BASE-BX 10-D / U awa.Eia hou, kaSFPʻO ke awa kūpono i lalo a kākoʻo iā 10 / 100 / 1000Mbps.I ka pōkole, kaSFPʻEhā mau pono nui ke awa:
● Kākoʻo i ka plug wela, hiki ke hōʻemi i ka hoʻonohonoho ʻana a me ka mālama mālama manawa;
● Hiki ke maʻalahi ke awa;
● Hoʻonui ka hoʻolālā paʻa i ka hilinaʻi;
● kūpono me 10 / 100 / 1000Mbps.
1. KaSFPawa o kaSFPʻōpona ʻōpika
SFPʻO ka module optical kahi mea hoʻopili e hoʻololi i nā hōʻailona uila gigabit i nā hōʻailona opi.ʻO ia ka maʻamau o ka ʻoihana liʻiliʻi a me ka pluggable gigabit optical transceiver integrated module.ʻElua wēlau oSFPmodule optical: ʻo kekahi hopenaSFPawa, hoʻokomo nui ʻia i loko o ke kuapo, router, media converter a me nā ʻenehana pūnaewele ʻē aʻe e hoʻololi i nā hōʻailona uila i nā hōʻailona optical no ka lawe ʻana;ʻO ka hopena ʻē aʻe ʻo LC interface a i ʻole RJ 45 interface, ka mea i hoʻohana nui ʻia e hoʻopili i ka fiber optical a i ʻole ke kelepona pūnaewele no ka lawe ʻana i ka ʻikepili.
2. KaSFPawa o ke kuapo gigabit
Hoʻololi GigabitSFPHiki ke hoʻopili ʻia ke awa i nā ʻano fiber like ʻole (e like me ka mode hoʻokahi a me ka fiber multimode) a me ka jumper pūnaewele (e like me Cat5e a me Cat6) e hoʻonui i ka hana hoʻololi o ka pūnaewele holoʻokoʻa, akā hoʻololi gigabitSFPpono e hoʻokomo mua ʻia ke awa ma mua o ka hoʻohana ʻanaSFPmodule optical, a laila e hoʻohana i ka fiber jumper a me ka lele pūnaewele no ka lawe ʻana i ka ʻikepili.Loaʻa nā hoʻololi ʻoihana āpau ma ka mākeke i kēia lā ma kahi o ʻeluaSFPnā awa i hiki ke kūkulu i nā topologies pūnaewele annular a i ʻole hōkū ma waena o nā hale like ʻole, nā papahele a i ʻole nā wahi ma o nā kaula e like me nā fibers optical a me nā lele lele.
He aha ka ʻokoʻa ma waenaSFPawa a me RJ 45 awa?
ʻOiai kaSFPʻO ke awa a me ka awa RJ 45 he 1000Mbps ka nui, aia kekahi mau ʻokoʻa ma waena o lākou.
1. Nā noi like ʻole
No ka laʻana, kaSFPPono e hoʻohālikelike ʻia ke awa ma ke kuapoSFPmodule optical a me ka hoʻohana ʻana i ka fiber jumper e ʻike i ka lawe ʻana i ka ʻikepili;a hiki i ka RJ 45 awa ma ke kuapo ke hoʻomaopopo pololei i ka hoʻouna ʻana i ka ʻikepili ma o ke kelepona pūnaewele.
2. He okoa ka mamao o ka lawe
ʻO ke awa ʻo RJ 45 ke alakaʻi nui nei i ka lawe ʻana i ka ʻikepili ma o ke kelepona pūnaewele, ʻo ka mamao loa o ka lawe ʻana o ke kelepona pūnaewele ʻo 100 m, ʻoiai kaSFPpono ke awa e hoohana i kaSFPʻO ka module optical e hoʻopili ai i ka jumper fiber optical no ka hoʻouna ʻana, a ʻo kona mamao hoʻouna kiʻekiʻe loa ʻo ia ka mamao hoʻouna kiʻekiʻe o kaSFPmodule optical, ʻo ia hoʻi, 160 mika.
SFPhiki ke hoohana ia na awaOLTa hoʻololi i nā mea hana.ʻO Shenzhen HDV Phoelectron Technology Co., Ltd. he mea hana ʻoihana pūnaewele meOLTmoʻo a me ka moʻo hoʻololi.I ka manawa like, loaʻa iā ia kahi pūʻulu ikaika a me nā lako polokalamu a me ka hui mua o ke kūʻai aku a ma hope o ke kūʻai aku, hiki ke hāʻawi i ka lawelawe maikaʻi loa no nā mea kūʻai.
