Inethiwekhi ye-EPON isebenzisa indlela ye-FTTB ukuze yakhe inethiwekhi, futhi amayunithi ayo enethiwekhi ayisisekelo yi-OLT ne-ONU. I-OLT ihlinzeka ngamachweba amaningi e-PON ukuze imishini yehhovisi emaphakathi ixhumeke kumishini ye-ONU; I-ONU iyithuluzi lomsebenzisi elihlinzeka ngedatha ehambisanayo nezindawo zokusebenzelana zezwi ukuze kutholakale isevisi yomsebenzisi...

I-ONU (iyunithi yenethiwekhi yokubona) inodi yokubona. I-ONU ihlukaniswe yaba iyunithi yenethiwekhi yokukhanya esebenzayo kanye neyunithi yenethiwekhi yelabhulali ye-passive optical network.Ngokujwayelekile, okokusebenza okufakwe ukuqapha kwenethiwekhi okuhlanganisa isitholi sokubonwayo, isidluliseli esikhanyayo esiphezulu kanye nezikhulisi zebhuloho eziningi zibizwa ngokuthi i-optical node....

Ngokuthuthuka kobuchwepheshe bedijithali, ubuchwepheshe bokuxhumana obubonakalayo kanye nobuchwepheshe besoftware kanye nokusetshenziswa okubanzi kwephrothokholi ye-TCP/IP, inethiwekhi yezokuxhumana, inethiwekhi yekhompiyutha kanye nenethiwekhi yethelevishini izohlangana futhi ibe munye ngaphansi kwe-IP ekwazi ukuhlinzeka ngezwi, da...

I-FTTH Fiber Circuit Classification Isendlalelo sokudlulisa se-FTTH sihlukaniswe izigaba ezintathu: iluphu ye-Duplex (dual fiber bidirectional), iluphu ye-Simplex (i-fiber eyodwa bidirectional) kanye ne-Triplex (i-fiber eyodwa ngendlela emithathu) iluphu. phakathi kokuphela kwe-OLT kanye ne-ON...

I-optical fibre transceiver iyiyunithi yokuguqula imidiya ye-Ethernet eshintshanisa amasiginali kagesi asontekile amabanga amafushane kanye namasiginali okubona amabanga amade. Ibizwa nangokuthi i-fiber converter ezindaweni eziningi. Imikhiqizo ivamise ukusetshenziswa ezindaweni zangempela zenethiwekhi lapho i-Eth...

Ukusetshenziswa kwe-EPON Technology ku-FTTx Access Network Ubuchwepheshe be-FTTx obusekelwe ku-EPON bunobuhle bomkhawulokudonsa ophezulu, ukwethembeka okuphezulu, izindleko zokulungisa eziphansi, kanye nobuchwepheshe obuvuthiwe. Okwesibili, yethula imodeli yohlelo lokusebenza ejwayelekile ye-EPON ku-FTTx, bese ihlaziya izici ezibalulekile ze-EPO...
