Monga tonse tikudziwa, ma switch a Gigabit Ethernet nthawi zambiri amakhala ndi mitundu iwiri yamadoko: madoko a RJ45 ndi madoko a SFP. Mitundu yonse iwiri yamadoko imatha kunyamula kutumiza kwa Gigabit Efaneti, ndiye pali kusiyana kotani pakati pawo? Ndi mtundu wanji wa doko la Gigabit Ethernet switch yomwe iyenera kugwiritsidwa ntchito kuzindikira kulumikizana kwa Gigabit Ethernet?

Kodi doko la RJ45 pa switch ya Gigabit Ethernet ndi chiyani?
Doko la RJ45 la switch ya Gigabit Ethernet ndi doko lomangidwa. Doko lamtunduwu litha kugwiritsidwa ntchito pofikira seva mu data center, LAN, ndi uplink wa masiwichi apakompyuta kapena Gigabit to desktop bandwidth application. Ma switch awiri a Gigabit Ethernet akalumikizidwa, zingwe zopotoka nthawi zambiri zimagwiritsidwa ntchito, monga CAT-5, CAT-5, CAT-6, ndi CAT-6 network jumpers.

Kodi doko la SFP pa switch ya Gigabit Ethernet ndi chiyani?

Doko la SFP (mawonekedwe ang'onoang'ono otentha osinthika) amatchedwanso doko la mini-GBIC, kuchuluka kwa kufalikira ndi 1G, ndipo imatha kuthandizira ulalo wamkuwa kapena ulalo wa kuwala (mu Ethernet, SFP port rate ndi 1Gbit/s, mu fiber channel system In, doko la SFP limatha kufikira 4Gbit / s). Mukayika gawo lamagetsi lamagetsi padoko la SFP, nthawi zambiri limalumikizidwa ndi chingwe cha netiweki (Cat5/Cat5e/Cat6) potumiza deta. Pamene gawo la optical port likulowetsedwa mu doko la SFP, muyenera kugwiritsa ntchito LC jumper kuti mutumize kuti mukwaniritse kufalikira kwautali. Kuphatikiza apo, pamapulogalamu monga malo opangira ma data ndi ma network amderali (LAN), doko la SFP losinthira lilinso ndi 100/1000Mbps yosinthira.

RJ45 doko VS SFP doko

Kuchokera pamalingaliro apamwambawa, machitidwe a doko la RJ45 ndi doko la SFP ndizofanana; koma kuchokera pakuwona mtengo, mtengo wa waya wa doko la SFP ndi wapamwamba. Komabe, doko la SFP ndilofunikabe chifukwa limatha kuthandizira mitundu iwiri ya ma module amagetsi a SFP ndi ma module a SFP optical port. Mukamagwiritsa ntchito ma SFP optical port optical modules, mtunda wotumizira umakhalanso wautali kuposa wa madoko a RJ45. M'magwiritsidwe ntchito, imakhala ndi kusinthasintha Kwapamwamba, ndipo scalability imakhalanso yokwera kwambiri.
