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

M'dziko lamaneti, ma switch amatenga gawo lofunikira pakulumikiza zida ndikuwongolera kuchuluka kwa data. Pamene ukadaulo ukupita, mitundu ya madoko yomwe imapezeka pa ma switch yakhala yosiyana, madoko a fiber optic ndi magetsi ndi omwe amapezeka kwambiri. Kumvetsetsa kusiyana pakati pa mitundu iwiriyi ya madoko ndikofunikira kwa akatswiri opanga maukonde ndi akatswiri a IT popanga ndi kukhazikitsa zida zogwirira ntchito zama network.

Madoko amagetsi
Madoko amagetsi pa ma switch nthawi zambiri amagwiritsa ntchito chingwe chamkuwa, monga zingwe zopotoka (monga, Cat5e, Cat6, Cat6a). Madokowa adapangidwa kuti azitumiza deta pogwiritsa ntchito ma siginecha amagetsi. Doko lodziwika bwino lamagetsi ndi cholumikizira cha RJ-45, chomwe chimagwiritsidwa ntchito kwambiri pamanetiweki a Efaneti.

Chimodzi mwazabwino zazikulu zamadoko amagetsi ndizovuta zake. Zingwe zamkuwa nthawi zambiri zimakhala zotsika mtengo kuposa ulusi, zomwe zimapangitsa kuti zikhale zodziwika bwino pama network ang'onoang'ono ndi apakatikati. Kuphatikiza apo, madoko amagetsi ndi osavuta kukhazikitsa ndi kukonza chifukwa safuna luso lapadera kapena zida kuti athetse.

Komabe, madoko amagetsi ali ndi malire potengera mtunda wotumizira ndi bandwidth. Zingwe zamkuwa nthawi zambiri zimakhala ndi mtunda wopitilira pafupifupi mamita 100, pambuyo pake kuwonongeka kwa chizindikiro kumachitika. Kuphatikiza apo, madoko amagetsi amatha kusokonezedwa ndi electromagnetic interference (EMI), zomwe zimatha kukhudza kukhulupirika kwa data komanso magwiridwe antchito a netiweki.

Doko la Optical
Komano, madoko a Fiber optic amagwiritsa ntchito zingwe za fiber optic kutumiza deta m'njira yowunikira. Madokowa adapangidwa kuti azitumiza mwachangu kwambiri pamayendedwe ataliatali, kuwapangitsa kukhala abwino kwa mabizinesi akuluakulu, malo opangira data, ndi kugwiritsa ntchito matelefoni. Madoko a Fiber optic amabwera m'njira zosiyanasiyana, kuphatikiza SFP (Small Form Factor Pluggable), SFP+, ndi QSFP (Quad Small Form Factor Pluggable), iliyonse imathandizira mitundu yosiyanasiyana ya data ndi mtunda wotumizira.

Ubwino waukulu wa madoko a fiber optic ndikutha kutumiza deta mtunda wautali (mpaka makilomita angapo) ndikutayika pang'ono. Izi zimawapangitsa kukhala abwino kulumikiza malo akutali kapena mapulogalamu apamwamba a bandwidth monga kutsatsa mavidiyo ndi cloud computing. Kuphatikiza apo, zingwe za fiber optic sizingasokonezedwe ndi electromagnetic interference (EMI), zomwe zimapereka kulumikizana kokhazikika komanso kodalirika.

Komabe, madoko a fiber optic amakhalanso ndi zovuta zawo. Mtengo woyamba wa zingwe za fiber optic ndi zida zomwe zimagwirizanitsidwa nazo ukhoza kukhala wokwera kwambiri kuposa njira zamkuwa. Kuphatikiza apo, kukhazikitsa ndi kuyimitsa zingwe za fiber optic kumafuna luso lapadera ndi zida, zomwe zimawonjezera nthawi ndi ndalama zotumizira.

Kusiyana kwakukulu

Sing'anga yotumizira: Doko lamagetsi limagwiritsa ntchito chingwe chamkuwa, ndipo doko la kuwala limagwiritsa ntchito chingwe cha fiber optic.
Kutalitali: Madoko amagetsi amangokhala pafupifupi 100 metres, pomwe madoko owoneka bwino amatha kutumiza deta pamtunda wamakilomita angapo.
Bandwidth: Fiber optic ports nthawi zambiri imathandizira ma bandwidth apamwamba kuposa madoko amagetsi, kuwapangitsa kukhala oyenera kugwiritsa ntchito zomwe zimafunidwa kwambiri.
Mtengo: Madoko amagetsi nthawi zambiri amakhala otsika mtengo pamayendedwe afupiafupi, pomwe madoko owonera amatha kuwononga mtengo woyambira koma atha kupereka phindu lanthawi yayitali pama network akulu.
Kusokoneza: Madoko owoneka sakhudzidwa ndi kusokonezedwa ndi ma elekitiroma, pomwe madoko amagetsi amakhudzidwa ndi EMI.

Pomaliza
Mwachidule, kusankha pakati pa ma fiber ndi madoko amagetsi pa switch kumatengera zinthu zosiyanasiyana, kuphatikiza zofunikira za netiweki, zovuta za bajeti, ndi magwiridwe antchito omwe mukufuna. Kwa maukonde ang'onoang'ono okhala ndi mtunda wochepera, madoko amagetsi angakhale okwanira. Komabe, kwa maukonde okulirapo, ochita bwino kwambiri omwe amafunikira kulumikizana kwakutali, ma doko a fiber ndiye chisankho chabwino kwambiri. Kumvetsetsa kusiyana kumeneku ndikofunikira kuti mupange zisankho zodziwitsidwa pakupanga ndi kukhazikitsa maukonde.
