Ezweni lokuxhumana, ama-switch adlala indima ebalulekile ekuxhumeni amadivayisi nasekuphatheni ithrafikhi yedatha. Njengoba ubuchwepheshe buthuthuka, izinhlobo zama-port atholakala kuma-switch ziye zahlukahluka, kanti ama-port e-fiber optic kanye ne-electrical yiwona avame kakhulu. Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili zama-port kubalulekile konjiniyela benethiwekhi kanye nochwepheshe be-IT lapho beklama futhi besebenzisa ingqalasizinda yenethiwekhi esebenza kahle.
Amachweba kagesi
Amachweba kagesi kumaswishi ngokuvamile asebenzisa izintambo zethusi, njengezintambo ezisontekile (isb., i-Cat5e, i-Cat6, i-Cat6a). Lawa machweba aklanyelwe ukudlulisa idatha kusetshenziswa izimpawu zikagesi. Ichweba kagesi elivame kakhulu isixhumi se-RJ-45, esisetshenziswa kabanzi kumanethiwekhi e-Ethernet.
Enye yezinzuzo eziyinhloko zamachweba kagesi ukuthi ayabiza kakhulu. Izintambo zethusi ngokuvamile zishibhile kunefayibha, okwenza zibe ukukhetha okuthandwayo kumanethiwekhi amancane naphakathi. Ngaphezu kwalokho, amachweba kagesi kulula ukuwafaka nokunakekela ngoba awadingi amakhono noma imishini ekhethekile ukuze aqedwe.
Kodwa-ke, amachweba kagesi anemikhawulo ngokwebanga lokudlulisa kanye nomkhawulokudonsa. Izintambo zethusi ngokuvamile zinebanga lokudlulisa eliphakeme elingamamitha ayi-100, ngemva kwalokho kwenzeka ukuwohloka kwesiginali. Ngaphezu kwalokho, amachweba kagesi asengozini enkulu yokuphazamiseka kwe-electromagnetic (EMI), okungathinta ubuqotho bedatha kanye nokusebenza kwenethiwekhi.
Imbobo ebonakalayo
Ngakolunye uhlangothi, ama-port e-fiber optic asebenzisa izintambo ze-fiber optic ukudlulisa idatha ngesimo sezimpawu zokukhanya. Lawa ma-port aklanyelwe ukudlulisa idatha ngesivinini esikhulu emabangeni amade, okwenza afaneleke kakhulu kumanethiwekhi amakhulu ebhizinisi, izikhungo zedatha, kanye nezinhlelo zokusebenza zokuxhumana. Ama-port e-fiber optic afika ngezindlela ezahlukahlukene, kufaka phakathi i-SFP (Small Form Factor Pluggable), i-SFP+, kanye ne-QSFP (Quad Small Form Factor Pluggable), ngalinye lisekela amazinga edatha ahlukene kanye namabanga okudlulisa.
Inzuzo eyinhloko yamachweba e-fiber optic yikhono lawo lokudlulisa idatha emabangeni amade (kufika kumakhilomitha amaningana) ngokulahlekelwa okuncane kwesiginali. Lokhu kuwenza abe mahle kakhulu ekuxhumeni izindawo ezikude noma ezinhlelweni zokusebenza ze-bandwidth ephezulu njengokusakaza ividiyo kanye ne-cloud computing. Ngaphezu kwalokho, izintambo ze-fiber optic azithinteki ekuphazamisekeni kwe-electromagnetic (EMI), okunikeza uxhumano oluzinzile noluthembekile.
Kodwa-ke, amachweba e-fiber optic nawo aletha izinselelo zawo. Izindleko zokuqala zezintambo ze-fiber optic kanye nehadiwe yazo ehlobene nazo zingaba phezulu kakhulu kunezixazululo zekhebula lethusi. Ngaphezu kwalokho, ukufaka nokuqeda izintambo ze-fiber optic kudinga amakhono akhethekile kanye nemishini, okwandisa isikhathi sokufakwa kanye nezindleko.
Umehluko omkhulu
I-transmission medium: I-port kagesi isebenzisa ikhebula lethusi, kanti i-optical port isebenzisa ikhebula le-fiber optic.
Ibanga: Amachweba kagesi anqunyelwe kumamitha angaba yi-100, kuyilapho amachweba optical engadlulisela idatha ngamakhilomitha amaningana.
Ububanzi Bomkhawulo: Amachweba e-fiber optic ngokuvamile asekela ububanzi bomkhawulo obuphezulu kunezichweba zikagesi, okwenza afaneleke ezinhlelweni zokusebenza ezifunwa kakhulu.
Izindleko: Amachweba kagesi ngokuvamile asebenza kahle kakhulu emabangeni amafushane, kuyilapho amachweba optical engase abize izindleko zokuqala eziphakeme kodwa anganikeza izinzuzo zesikhathi eside kumanethiwekhi amakhulu.
Ukuphazamiseka: Ama-port optical awathinteki ukuphazamiseka kwe-electromagnetic, kuyilapho ama-port kagesi ethintekile yi-EMI.
Ekuphetheni
Ngamafuphi, ukukhetha phakathi kwe-fiber kanye nama-electrical port ku-switch kuncike ezintweni ezahlukahlukene, kufaka phakathi izidingo ezithile zenethiwekhi, imikhawulo yesabelomali, kanye nokusebenza okufiselekayo. Kumanethiwekhi amancane anamabanga alinganiselwe, ama-electrical port anganela. Kodwa-ke, kumanethiwekhi amakhulu, asebenza kahle adinga ukuxhumana kwebanga elide, ama-fiber port ayisinqumo esingcono kakhulu. Ukuqonda lo mehluko kubalulekile ekwenzeni izinqumo ezinolwazi ekwakhiweni nasekusetshenzisweni kwenethiwekhi.
