Ezweni lanamuhla elixhunyiwe, ingqalasizinda yenethiwekhi ethembekile nesebenzayo ibalulekile kumabhizinisi nakubaqhubi. I-POE switch ingenye yezingxenye ezibalulekile ezidlala indima ebalulekile ekuxhumaneni kwenethiwekhi. Ama-PoE switch asebenzisa ubuchwepheshe obuthuthukisiwe futhi alandela amazinga embonini ukuhlinzeka abaqhubi nge-EPON OLT ehlanganisiwe kakhulu, enomthamo ophakathi, okwenza kube ukukhetha okuhle kwamanethiwekhi okufinyelela kanye namanethiwekhi ekhampasi yebhizinisi. Kule bhulogi, sizohlola ukuthi ama-POE switch angakhulisa kanjani ukusebenza kahle kwenethiwekhi, izidingo zawo zobuchwepheshe, kanye nezinzuzo eziletha emabhizinisini.
Incazelo kanye nomsebenzi weswishi ye-POE:
I-POE switchisifinyezo se-Power over Ethernet switch, okuyidivayisi ehlanganisa imisebenzi yokudlulisa idatha kanye nokunikezwa kwamandla ibe yiyunithi eyodwa. Zenzelwe njenge-EPON OLTs yohlobo lwebhokisi oluhlanganisiwe oluphezulu, olunomthamo ophakathi, ezihambisana nezindinganiso zobuchwepheshe ze-IEEE802.3 ah futhi zihlangabezana nezidingo zemishini ye-YD/T 1945-2006 EPON OLT. Lezi zishintshi zinikeza ubulula kanye nokulula ngokuqeda isidingo sentambo kagesi ehlukile, okwandisa ukusebenza kahle kanye nokunciphisa izindleko.
Izidingo zobuchwepheshe kanye nokuvuleleka:
Ukuthuthukiswa kwamaswishi e-POE kunaka kakhulu izidingo zobuchwepheshe. Alandela indinganiso ye-Ethernet Passive Optical Network (EPON), aqinisekisa ukuhlanganiswa okungenamthungo nezinhlelo zenethiwekhi ezikhona. Ngaphezu kwalokho, aklanyelwe ukuhlangabezana nezidingo zobuchwepheshe ze-EPON 3.0 ezibekwe yi-China Telecom. Amaswishi e-POE alandela lezi zindinganiso, anokuvuleka okuhle, futhi angahlanganiswa kalula futhi ahambisane namadivayisi ahlukahlukene enethiwekhi.
Umthamo omkhulu, ukuthembeka okuphezulu:
Isici esivelele samaswishi e-POE umthamo wawo omkhulu, okwandisa ukusabalala njengoba inethiwekhi ikhula. Amabhizinisi angandisa ingqalasizinda yawo yenethiwekhi ngaphandle kokukhathazeka ngomthamo olinganiselwe. Ngaphezu kwalokho, amaswishi e-POE anokwethenjelwa okuphezulu ukuqinisekisa ukuxhumana okungaphazamiseki kwezinhlelo zokusebenza ezibalulekile nokunciphisa isikhathi sokungasebenzi. Lokhu kuzinza kubalulekile kumabhizinisi athembele kakhulu ekuxhumekeni kwenethiwekhi emisebenzini yansuku zonke.
Isofthiwe inemisebenzi ephelele kanye nokusetshenziswa kwe-bandwidth ephezulu:
Ama-switch e-POE ahlonyiswe ngemisebenzi yesofthiwe ephelele, okwenza opharetha bakwazi ukuphatha nokuthuthukisa amanethiwekhi abo ngempumelelo. Izici ezifana nokusekelwa kwe-VLAN, ikhwalithi yesevisi (i-QoS), kanye nokulawulwa kwethrafikhi kwenza amabhizinisi akwazi ukubeka phambili izinhlelo zokusebenza ezibalulekile futhi aqinisekise ukusetshenziswa kahle kwe-bandwidth. Lesi sici sinikeza ukulawula okuphezulu kanye nokuguquguquka phezu kwethrafikhi yenethiwekhi, okuthuthukisa ukusebenza kwenethiwekhi iyonke.
Izinzuzo zebhizinisi:
UkuhlanganisaAmaswishi e-POEUkufaka ingqalasizinda yenethiwekhi kungaletha izinzuzo eziningi emabhizinisini. Okokuqala, inqubo yokufaka elula inciphisa ubunzima kanye nezindleko ezihambisana nezintambo zikagesi ezihlukene. Okwesibili, ukusabalala okuphezulu kanye nokuthembeka kwamaswishi e-POE kwenza inethiwekhi ivikeleke esikhathini esizayo futhi izivumelanise nokukhula ngaphandle kokuphazamiseka. Ngaphezu kwalokho, izici zesofthiwe ziqinisekisa ukusetshenziswa kwe-bandwidth okuphumelelayo, kwandise umkhiqizo futhi kunikeze ulwazi lomsebenzisi olubushelelezi. Okokugcina, ukwamukela amaswishi e-POE kuvumela amabhizinisi ukuthi ahlale ehambisana nezindinganiso zemboni, okwenza kube lula ukuhlanganiswa nezinye izinhlelo namadivayisi.
Ekuphetheni:
Ukuhlanganiswa kwama-POE switch engqalasizinda yenethiwekhi kulethe izinzuzo ezinkulu kubasebenzi kanye namabhizinisi. Lawa ma-switch anikeza izici eziningi ezifana nomthamo ophezulu, ukuthembeka okuphezulu, ukusebenza okugcwele kwesofthiwe kanye nokusetshenziswa kwe-bandwidth okuphumelelayo, okwandisa ukusebenza kahle kwenethiwekhi kanye nokwenza lula inqubo yokufaka ngenkathi kulandelwa amazinga embonini. Ngokutshala imali kuma-POE switch, amabhizinisi angakha indawo yenethiwekhi eqinile nekhuliswayo esekela ukukhula kwawo futhi iqinisekise ukuxhumana okungaphazanyiswa endaweni yanamuhla yedijithali eshintsha ngokushesha.
