Masiku ano, m'mapulojekiti amakono olankhulirana pa intaneti, ma transceivers optical, optical fiber transceivers, ndi modem optical anganene kuti amagwiritsidwa ntchito kwambiri komanso amalemekezedwa kwambiri ndi ogwira ntchito zachitetezo. Ndiye, kodi mukudziwa kusiyana pakati pa atatuwa Omveka? Optical modem ndi mtundu wa zida ...

Optical fiber transceiver ndi Ethernet transmission media conversion unit yomwe imasinthanitsa ma siginecha amagetsi opotoka mtunda waufupi ndi ma sign atali atali. Malingana ndi zosowa zake, zimagawidwa makamaka kukhala ma transceivers opangidwa ndi fiber single-fiber optical transceivers ndi ma transceivers opangidwa ndi fiber.

Kapangidwe kake ka ulusi wa kuwala Ulusi wopanda kanthu wa ulusi wa kuwala nthawi zambiri umagawika m'magulu atatu: pachimake, chotchinga ndi zokutira. Pakatikati pa fiber ndi zotchingira zimapangidwa ndi galasi lokhala ndi ma refractive indexes osiyanasiyana, pakati ndi magalasi apamwamba a refractive index (germanium-doped silica), ndi ...

1.PON Introduction (1) Kodi teknoloji ya PON PON (passive optical network) (kuphatikizapo EPON, GPON) ndiyo teknoloji yayikulu yoyendetsera chitukuko cha FTTx (fiber kunyumba). Itha kupulumutsa zida zam'mbuyo zam'mbuyo komanso milingo yamanetiweki, ndipo imatha kupereka njira ziwiri zapamwamba za bandwidth ...

Kugwiritsiridwa ntchito kwa ma transceivers optical fiber mumapulojekiti ofooka apano ndikofala kwambiri, ndiye timasankha bwanji ma transceivers opangira ma projekiti aumisiri? Pamene fiber optic transceiver ikulephera, mungasamalire bwanji? 1.Kodi fiber optic transceiver ndi chiyani? Optical fiber transceiver amatchedwanso ph ...

Tisanamvetsetse kusintha kwa PoE, choyamba tiyenera kumvetsetsa kuti PoE ndi chiyani. PoE ndi mphamvu zamagetsi paukadaulo wa Ethernet. Ndi njira yoperekera mphamvu patali pazida zolumikizidwa pamanetiweki (monga Wireless LAN AP, IP Phone, Bluetooth AP, IP Camera, etc.) pa chingwe cha data cha Ethernet, el ...
