Ama-transceiver e-optical kanye nama-switch womabili abalulekile ekudlulisweni kwe-Ethernet, kodwa ahlukile ngokusebenza kanye nokusetshenziswa. Ngakho-ke, uyini umehluko phakathi kwama-transceiver e-fiber optic kanye nama-switch?
Uyini umehluko phakathi kwama-transceivers e-fiber optic nama-switch?
I-transceiver yefayibha ye-optical iyithuluzi elingabizi kakhulu futhi eliguquguqukayo. Ukusetshenziswa okuvamile ukuguqula izimpawu zikagesi ngamabili asontekile zibe izimpawu ezibonakalayo. Ngokuvamile isetshenziswa ezintanjeni zethusi ze-Ethernet ezingenakumbozwa futhi kumele zisebenzise imicu ye-optical ukuze kwandiswe ibanga lokudlulisela. Endaweni yangempela yenethiwekhi, idlala indima enkulu ekusizeni ukuxhuma imayela lokugcina lemigqa ye-fiber optic kunethiwekhi yendawo yedolobha kanye nenethiwekhi yangaphandle. Iswishi iyidivayisi yenethiwekhi esetshenziselwa ukudlulisa isignali kagesi (optical). Idlala indima ebalulekile ekuxhumaneni okuhlangene phakathi kwamadivayisi enethiwekhi anezintambo (njengamakhompyutha, amaphrinta, amakhompyutha, njll.) Amakati afinyelela kuwebhu.
Izinga lokudlulisa
Njengamanje, ama-transceiver e-fiber optic angahlukaniswa abe ama-transceiver e-fiber optic angu-100M, ama-transceiver e-fiber optic e-gigabit kanye nama-transceiver e-fiber optic angu-10G. Avame kakhulu kulawa ama-transceiver e-Fast and Gigabit, ayizixazululo ezingabizi kakhulu nezisebenzayo kumanethiwekhi asekhaya namabhizinisi amancane naphakathi. Ama-switch enethiwekhi afaka ama-switch angu-1G, 10G, 25G, 100G kanye no-400G. Uma sibheka amanethiwekhi amakhulu esikhungo sedatha njengesibonelo, ama-switch angu-1G/10G/25G asetshenziswa kakhulu kungqimba lokufinyelela noma njenge-switch ye-ToR, kuyilapho ama-switch angu-40G/100G/400G esetshenziswa kakhulu njenge-core noma i-Backbone switch.
Ubunzima bokufaka
Ama-transceiver e-optical ayimishini yehadiwe yenethiwekhi elula kakhulu enezixhumi ezimbalwa kunezishintshi, ngakho-ke izintambo zawo kanye nokuxhumeka kulula kakhulu. Angasetshenziswa ewodwa noma afakwe ku-rack. Njengoba i-transceiver ye-optical iyidivayisi ye-plug-and-play, izinyathelo zayo zokufaka nazo zilula kakhulu: vele ufake ikhebula lethusi elihambisanayo kanye ne-jumper ye-optical fiber echwebeni likagesi elihambisanayo kanye nechwebeni le-optical, bese uxhuma ikhebula lethusi kanye ne-optical fiber emishinini yenethiwekhi. Zombili iziphetho zizokwenza.
Iswishi yenethiwekhi ingasetshenziswa yodwa kunethiwekhi yasekhaya noma ehhovisi elincane, noma ingafakwa erekhini kunethiwekhi enkulu yesikhungo sedatha. Ngaphansi kwezimo ezivamile, kuyadingeka ukufaka imojula echwebeni elifanele, bese usebenzisa ikhebula lenethiwekhi elifanele noma i-jumper ye-optical fiber ukuze uxhumeke kukhompyutha noma eminye imishini yenethiwekhi. Endaweni yokuxhuma izintambo ezixinene kakhulu, amaphaneli okuhlanganisa, amabhokisi ezintambo kanye namathuluzi okuphatha izintambo ayadingeka ukuphatha izintambo nokwenza kube lula ukuxhuma izintambo. Kumaswishi enethiwekhi aphethwe, kudingeka afakwe eminye imisebenzi ethuthukisiwe, njenge-SNMP, i-VLAN, i-IGMP neminye imisebenzi.
