Kodi OLT imodzi ingalumikizane ndi ma ONU angati?

64, nthawi zambiri zosakwana 10.

1. Mwachidziwitso, 64 ikhoza kulumikizidwa, koma poganizira kuchepetsedwa kwa kuwala ndi kukhudzidwa kwa onu ku kuwala, mwazochita zogwiritsidwa ntchito, chiwerengero cha kugwirizana pa doko ndi osachepera 10. Chiwerengero chachikulu cha ogwiritsa ntchito olt ndi makamaka zochepa ndi zikhalidwe zitatu, zomwe ndi, kuchuluka kwa bandwidth yautumiki ndi ma adilesi a MAC omwe ogwiritsa ntchito angapeze.

2.olt (optical line terminal) optical line terminal.Pogwiritsa ntchito ukadaulo wa pon, zida za olt ndizofunikira kwambiri muofesi.Ntchito yomwe imazindikira ndikulumikiza chosinthira chakutsogolo ndi chingwe cha netiweki, ndikuchisintha kukhala chizindikiro cha kuwala, ndikugwiritsa ntchito chingwe cholumikizira kuti chilumikizane ndi chogawa chamagetsi pamapeto ogwiritsira ntchito.Zindikirani kuwongolera, kasamalidwe ndi ntchito zosiyanasiyana za onu ya zida zogwiritsira ntchito.Monga chipangizo cha onu, chipangizo cha olt ndi chipangizo chophatikizika cha optoelectronic.

3.onu (optical network unit) optical node.onu imagawidwa kukhala gawo logwira ntchito la optical network ndi passive optical network unit.Nthawi zambiri, zida zomwe zimakhala ndi kuwunika kwa netiweki kuphatikiza cholandila chowoneka bwino, ma transmitter oplink optical, ndi ma amplifiers angapo a mlatho amatchedwa optical node.
