PoE hloov yog hloov pauv uas txhawb nqa lub zog rau lub network cable. Piv nrog rau qhov hloov pauv zoo tib yam, lub tshuab txais hluav taws xob tau txais hluav taws xob (xws li AP, lub koob yees duab digital, thiab lwm yam) tsis tas yuav tsum tau xaim hluav taws xob, thiab kev ntseeg siab ntawm tag nrho cov network yog siab dua. Qhov txawv ntawm Po...

Raws li ib feem tseem ceeb ntawm kev sib txuas lus kho qhov muag, optical fiber module ua haujlwm li photoelectric hloov dua siab tshiab, kom cov teeb liab kis tau rau hauv optical fibers. Yog li, koj puas paub yuav ua li cas paub qhov txawv ntawm qhov optical fiber module yog ib hom lossis ntau hom? Nov yog ob peb txoj hauv kev kom paub qhov txawv ...

Optical modules tuaj yeem muab faib ua ib leeg-fiber thiab dual-fiber raws li tus naj npawb ntawm cov interfaces. Dual-fiber optical modules muaj ob qhov kho qhov muag fiber ntau interfaces, thiab ib leeg-fiber optical modules tsuas muaj ib qho kev sib txuas ntawm fiber ntau. Ntxiv nrog rau qhov sib txawv ntawm fiber ntau optical interfaces ...

Lub optical fiber transceiver tseem ceeb tsuas yog ua tiav cov ntaub ntawv hloov dua siab tshiab ntawm cov xov xwm sib txawv, uas tuaj yeem paub txog kev sib txuas ntawm cov khoos phis tawj lossis cov keyboards ntawm ob qho kawg hauv 0-100KM, tab sis muaj ntau qhov txuas ntxiv hauv cov ntawv thov siv tau. Tom qab ntawd, dab tsi yog cov ntawv thov tshwj xeeb o ...

Dab tsi yog lub network qauv ntawm Optical Access Network (OAN) Optical access network (OAN) yog hais txog kev siv cov fiber ntau optical ua qhov nruab nrab kis tau tus mob kom paub txog cov ntaub ntawv kis tau tus mob ntawm kev nkag network. Nws txuas nrog rau qhov kev pabcuam ntawm cov kab kho qhov muag te ...

Nrog rau kev txhim kho txuas ntxiv ntawm kev tsim kho kev sib txuas ceev ceev thiab xav tau los tsim lub neej ntse digital raws li "peb gigabit" network muaj peev xwm, cov neeg ua haujlwm xav tau kev sib kis ntev dua, bandwidths siab dua, muaj kev ntseeg siab dua thiab kev lag luam qis dua ...
