Kusiyana pakati pa ma switch a fiber optic ndi ma transceivers a fiber optic!

Ma transceiver a kuwala ndi ma switch onse ndi ofunikira kwambiri pa kutumiza kwa Ethernet, koma amasiyana mu ntchito ndi kagwiritsidwe ntchito. Ndiye, kodi kusiyana pakati pa ma transceiver a fiber optic ndi ma switch ndi kotani?

Kodi kusiyana pakati pa ma transceivers a fiber optic ndi ma switch ndi kotani?

Chosinthira ulusi wa kuwala ndi chipangizo chotsika mtengo kwambiri komanso chosinthasintha. Chogwiritsidwa ntchito kwambiri ndikusintha ma siginecha amagetsi m'magawo awiriawiri kukhala ma siginecha a kuwala. Nthawi zambiri chimagwiritsidwa ntchito mu zingwe zamkuwa za Ethernet zomwe sizingaphimbidwe ndipo ziyenera kugwiritsa ntchito ulusi wa kuwala kuti ziwonjezere mtunda wotumizira. Mu netiweki yeniyeni, imagwiranso ntchito yayikulu pothandiza kulumikiza mtunda womaliza wa mizere ya fiber optic ku netiweki ya m'dera la mzinda ndi netiweki yakunja. Chosinthira ndi chipangizo cha netiweki chomwe chimagwiritsidwa ntchito potumiza ma siginecha amagetsi (optical). Chimagwira ntchito yofunika kwambiri pakulankhulana pakati pa zida za netiweki zama waya (monga makompyuta, osindikiza, makompyuta, ndi zina zotero). Amphaka amalowa pa intaneti.

Kuchuluka kwa kutumiza

Pakadali pano, ma transceiver a fiber optic amatha kugawidwa m'ma transceiver a fiber optic a 100M, ma transceiver a fiber optic a gigabit ndi ma transceiver a fiber optic a 10G. Odziwika kwambiri mwa awa ndi ma transceiver a Fast ndi Gigabit, omwe ndi njira zotsika mtengo komanso zogwira mtima m'mabizinesi apakhomo ndi ang'onoang'ono. Ma switch a network akuphatikizapo ma switch a 1G, 10G, 25G, 100G ndi 400G. Mwachitsanzo, ma switch a 1G/10G/25G amagwiritsidwa ntchito makamaka pa access layer kapena ngati ma switch a ToR, pomwe ma switch a 40G/100G/400G amagwiritsidwa ntchito kwambiri ngati core kapena Backbone switch.

Kuvuta kwa kukhazikitsa

Ma transceiver a kuwala ndi zida zosavuta kugwiritsa ntchito pa netiweki zomwe zili ndi ma interface ochepa kuposa ma switch, kotero mawaya awo ndi maulumikizidwe awo ndi osavuta. Angagwiritsidwe ntchito okha kapena kuyikidwa pa raki. Popeza transceiver ya kuwala ndi chipangizo cholumikizira ndi kusewera, njira zake zoyikira nazonso ndizosavuta: ingolowetsani chingwe chogwirizana cha mkuwa ndi jumper ya ulusi wowala mu doko lamagetsi logwirizana ndi doko la kuwala, kenako lumikizani chingwe cha mkuwa ndi ulusi wowala ku zida za netiweki. Malekezero onse awiri adzagwira ntchito.

Chosinthira cha netiweki chingagwiritsidwe ntchito chokha pa netiweki yapakhomo kapena ofesi yaying'ono, kapena chikhoza kuyikidwa pa raki mu netiweki yayikulu ya data center. Nthawi zambiri, ndikofunikira kuyika module mu doko loyenera, kenako kugwiritsa ntchito chingwe cholumikizira cha netiweki kapena jumper ya fiber yowunikira kuti mulumikizane ndi kompyuta kapena zida zina za netiweki. Mu malo okhala ndi ma waya ambiri, mapanelo a patch, mabokosi a fiber ndi zida zowongolera ma waya ndizofunikira kuti muyang'anire ma waya ndikupangitsa kuti ma waya akhale osavuta. Pa ma switch a netiweki oyendetsedwa, amafunika kukhala ndi ntchito zina zapamwamba, monga SNMP, VLAN, IGMP ndi ntchito zina.
