Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili zama-port kubalulekile konjiniyela benethiwekhi kanye nochwepheshe be-IT lapho beklama futhi besebenzisa ukusebenza kahle...Funda kabanzi -
'Iphalethi yombala' ezweni le-fiber optic: kungani ibanga lokudlulisela lamamojula optical lihluka kakhulu
Ezweni lokuxhumana kwe-fiber optic, ukukhethwa kobubanzi bokukhanya kufana nokulungiswa kwemvamisa yomsakazo kanye nokukhetha iziteshi. Kuphela ngokukhetha "isiteshi" esifanele lapho isignali ingadluliselwa khona ngokucacile nangokuzinzile. Kungani amanye amamojula okukhanya enebanga lokudlulisela elingamamitha angu-500 kuphela, kanti amanye angadlula amakhulu amakhilomitha? Imfihlakalo ilele 'embala'.Funda kabanzi -
Indlela Ama-Fiber Optic Reflectors Asetshenziswa Ngayo Ekuqapheni Izixhumanisi Zenethiwekhi ye-PON
Kumanethiwekhi e-PON (Passive Optical Network), ikakhulukazi ngaphakathi kwe-topology eyinkimbinkimbi ye-PON ODN (Optical Distribution Network), ukuqapha okusheshayo kanye nokuxilongwa kwamaphutha e-fiber kuletha izinselele ezinkulu. Nakuba ama-reflectometer e-optical time domain (OTDRs) angamathuluzi asetshenziswa kabanzi, ngezinye izikhathi awanakho ukuzwela okwanele kokuthola ukuncishiswa kwesignali kuma-fiber egatsha le-ODN noma...Funda kabanzi -
Ukuhlaziywa Kokuklama Nokwenza Kahle I-FTTH Network Splitter
Ekwakhiweni kwenethiwekhi ye-fiber-to-the-home (FTTH), ama-optical splitter, njengezingxenye eziyinhloko zamanethiwekhi e-optical angasebenzi (ama-PON), avumela ukwabelana ngabasebenzisi abaningi kwe-fiber eyodwa ngokusatshalaliswa kwamandla e-optical, okuthinta ngqo ukusebenza kwenethiwekhi kanye nokuhlangenwe nakho komsebenzisi. Lesi sihloko sihlaziya ngokuhlelekile ubuchwepheshe obubalulekile ekuhleleni kwe-FTTH kusuka emibonweni emine: i-optical splitter...Funda kabanzi -
Ukuvela Kobuchwepheshe Kwe-Optical Cross-Connect (OXC)
I-OXC (optical cross-connect) inguqulo ethuthukisiwe ye-ROADM (Reconfigurable Optical Add-Drop Multiplexer).
