Ngophuhliso olukhawulezayo lwenethiwekhi, imodyuli ye-SFP ye-optical ibe yinxalenye eyimfuneko yenkqubo yenethiwekhi.Ngoko ke ungakanani ulwazi malunga neprotocol ye-SFP?Namhlanje makhe ndikunike isingeniso esifutshane kwiprotocol ye-SFP-8472.I-Sff-8472 yiprothokholi enemithombo emininzi yokubeka iliso kwidijithali...

I-WiFi6 entsha isekela i-802.11ax mode, ngoko yintoni umehluko phakathi kwe-802.11ax kunye ne-802.11ac mode?Xa kuthelekiswa ne-802.11ac, i-802.11ax iphakamisa iteknoloji entsha ye-multiplexing yendawo, enokuchonga ngokukhawuleza kwaye ibuyise iingxabano zomoya.Ngeli xesha, inokuchonga imiqondiso yokuphazamiseka ...

Zombini iimodyuli zefiber enye kunye ne-fiber optical ezimbini zinokusasaza kwaye zifumane.Kuba ezi zimbini zonxibelelwano kufuneka zikwazi ukuthumela nokufumana.Umahluko kukuba imodyuli enye yefiber optical inezibuko elinye kuphela.Itekhnoloji ye-Wavelength division multiplexing (WDM) isetyenziselwa ukudibanisa iirece ezahlukeneyo...

1. Imbonakalo eyahlukileyo: Imodyuli ye-fiber optical ephindwe kabini: Kukho iisokethi ezimbini ze-fiber optical, ngokulandelanayo, ukuthumela (TX) kunye nokufumana (RX) izibuko ze-optical.Iifiber ezimbini ze-optical kufuneka zifakwe, kwaye izibuko ezahlukeneyo ze-optical kunye ne-optical fibers zisetyenziselwa ukuhanjiswa kwedatha kunye nokwamkelwa;Xa u...

I-DDM yemodyuli ye-optical yindlela yokubeka iliso kwiiparamitha.Ayinayo kuphela i-alamu kunye nemisebenzi yesilumkiso, kodwa kunye nokubikezelwa kwempazamo kunye nemisebenzi yendawo yempazamo.Kukho iindlela ezimbini eziphambili zokujonga ulwazi lweDDM lwemodyuli ye-optical: SNMP kunye nomyalelo.1. I-SNMP, eyile Abaphathi beNethiwekhi abaLula...

1. Ukuqikelelwa kobomi bemodyuli ye-Optical Ngokubeka iliso ngexesha langempela lombane osebenzayo kunye nobushushu ngaphakathi kwimodyuli ye-transceiver, umlawuli wenkqubo unokufumana ezinye iingxaki ezinokuthi zibe khona: a.Ukuba umbane weVcc uphezulu kakhulu, uya kuzisa ukophuka kwezixhobo zeCMOS;Umbane weVcc uphantsi kakhulu, a...
