Kodi kusiyana pakati pa doko la kuwala ndi doko lamagetsi la switch ndi kotani?

Mu dziko la maukonde, ma switch amagwira ntchito yofunika kwambiri polumikiza zida ndikuwongolera kuchuluka kwa deta. Pamene ukadaulo ukusintha, mitundu ya ma doko omwe amapezeka pa ma switch yakhala ikusiyana, ndipo ma fiber optic ndi ma doko amagetsi ndi omwe amapezeka kwambiri. Kumvetsetsa kusiyana pakati pa mitundu iwiriyi ya ma doko ndikofunikira kwambiri kwa mainjiniya a maukonde ndi akatswiri a IT popanga ndikugwiritsa ntchito zomangamanga zamaukonde moyenera.

Madoko amagetsi
Madoko amagetsi pa ma switch nthawi zambiri amagwiritsa ntchito zingwe zamkuwa, monga zingwe zopindika (monga Cat5e, Cat6, Cat6a). Madoko awa adapangidwa kuti atumize deta pogwiritsa ntchito zizindikiro zamagetsi. Chingwe chodziwika kwambiri chamagetsi ndi cholumikizira cha RJ-45, chomwe chimagwiritsidwa ntchito kwambiri mu ma network a Ethernet.

Chimodzi mwa ubwino waukulu wa madoko amagetsi ndi kutsika mtengo kwawo. Zingwe zamkuwa nthawi zambiri zimakhala zotsika mtengo kuposa ulusi, zomwe zimapangitsa kuti zikhale zodziwika bwino pamaukonde ang'onoang'ono ndi apakatikati. Kuphatikiza apo, madoko amagetsi ndi osavuta kuyika ndi kusamalira chifukwa safuna luso lapadera kapena zida zapadera kuti athetsedwe.

Komabe, madoko amagetsi ali ndi zoletsa pankhani ya mtunda wotumizira uthenga ndi bandwidth. Zingwe zamkuwa nthawi zambiri zimakhala ndi mtunda wotumizira uthenga wa pafupifupi mamita 100, pambuyo pake chizindikiro chimawonongeka. Kuphatikiza apo, madoko amagetsi amakhala pachiwopsezo chachikulu cha kusokonezedwa ndi ma electromagnetic interference (EMI), zomwe zingakhudze kukhulupirika kwa deta ndi magwiridwe antchito a netiweki.

Doko lowala
Koma ma fiber optic ports, amagwiritsa ntchito zingwe za fiber optic kutumiza deta mu mawonekedwe a zizindikiro za kuwala. Ma ports awa apangidwa kuti azitha kutumiza deta mwachangu kwambiri pamtunda wautali, zomwe zimapangitsa kuti akhale abwino kwambiri pama network akuluakulu, malo osungira deta, ndi ntchito zolumikizirana. Ma fiber optic ports amabwera m'njira zosiyanasiyana, kuphatikizapo SFP (Small Form Factor Pluggable), SFP+, ndi QSFP (Quad Small Form Factor Pluggable), iliyonse imathandizira kuchuluka kwa deta ndi mtunda wotumizira deta.

Ubwino waukulu wa ma fiber optic ports ndi kuthekera kwawo kutumiza deta patali (mpaka makilomita angapo) popanda kutaya chizindikiro champhamvu. Izi zimapangitsa kuti zikhale zabwino kwambiri polumikizira malo akutali kapena kugwiritsa ntchito ma bandwidth apamwamba monga kuwonera makanema ndi cloud computing. Kuphatikiza apo, ma fiber optic cables sakhudzidwa ndi kusokonezeka kwa electromagnetic (EMI), zomwe zimapangitsa kuti kulumikizana kukhale kokhazikika komanso kodalirika.

Komabe, madoko a fiber optic nawonso ali ndi mavuto awoawo. Mtengo woyamba wa zingwe za fiber optic ndi zida zake ukhoza kukhala wokwera kwambiri kuposa mayankho a zingwe zamkuwa. Kuphatikiza apo, kukhazikitsa ndi kuthetsa zingwe za fiber optic kumafuna luso lapadera ndi zida, zomwe zimawonjezera nthawi ndi ndalama zogwiritsira ntchito.

Kusiyana kwakukulu

Cholumikizira chamagetsi: Cholumikizira chamagetsi chimagwiritsa ntchito chingwe cha mkuwa, ndipo cholumikizira chamagetsi chimagwiritsa ntchito chingwe cha fiber optic.
Kutali: Madoko amagetsi ali ndi malire a pafupifupi mamita 100, pomwe madoko owonera amatha kutumiza deta pamtunda wa makilomita angapo.
Bandwidth: Madoko a fiber optic nthawi zambiri amathandizira bandwidth yayikulu kuposa madoko amagetsi, zomwe zimapangitsa kuti akhale oyenera kugwiritsa ntchito omwe amafunidwa kwambiri.
Mtengo: Madoko amagetsi nthawi zambiri amakhala otsika mtengo kwambiri pa mtunda waufupi, pomwe madoko owonera amatha kukhala ndi mtengo wokwera poyamba koma angapereke phindu la nthawi yayitali pa maukonde akuluakulu.
Kusokoneza: Madoko owonera sakhudzidwa ndi kusokoneza kwa maginito, pomwe madoko amagetsi amakhudzidwa ndi EMI.

Pomaliza
Mwachidule, kusankha pakati pa madoko a fiber ndi magetsi pa switch kumadalira zinthu zosiyanasiyana, kuphatikizapo zofunikira zenizeni za netiweki, zoletsa bajeti, ndi magwiridwe antchito omwe mukufuna. Kwa ma netiweki ang'onoang'ono omwe ali ndi mtunda wochepa, madoko amagetsi angakhale okwanira. Komabe, kwa ma netiweki akuluakulu komanso ogwira ntchito kwambiri omwe amafunikira kulumikizana kwakutali, madoko a fiber ndiye chisankho chabwino kwambiri. Kumvetsetsa kusiyana kumeneku ndikofunikira kwambiri popanga zisankho zodziwa bwino pakupanga ndi kukhazikitsa netiweki.
