Ngomphathi / 30 Jun 20 /0Amazwana Ifakwe kuphi imojuli ye-optical? Imishini ethile: i-transceiver optical, i-optical fibre transceiver, switch, ikhadi lenethiwekhi ye-optical, i-optical fibre router, i-optical fiber high-speed dome, i-base station, i-repeater, njll. Amabhodi e-optical port emishini yokudlulisa ejwayelekile afakwe amamojula ahambisanayo optical. Ukuze uthole imininingwane...

Ukunemba okuphezulu kwebhodi lesifunda kubhekisela ekusetshenzisweni kobubanzi/isikhala somugqa ocolekile, izimbobo ezincane, ububanzi bendandatho encane (noma ukungabi nobubanzi bendandatho), kanye nezimbobo ezigqitshiwe nezingaboni ukuze kuzuzwe ukuminyana okuphezulu. Ukunemba okuphezulu kubhekisela kumphumela othi "mncane, omncane, omncane, omncane" uzoletha ... Funda kabanzi Ngomphathi / 24 Jun 20 /0Amazwana Qonda ngokugcwele i-EPON, i-GPON I-PON (Passive Optical Network) iyinethiwekhi ye-passive Optical network, okusho ukuthi i-ODN (inethiwekhi yokusabalalisa optical) phakathi kwe-OLT (optical line terminal) kanye ne-ONU (optical network unit) ayinayo into esebenzayo, futhi isebenzisa kuphela imicu yokubona. kanye nezingxenye ze-passive. I-PON yamukela ikakhulukazi... Funda kabanzi Ngomphathi / 18 Jun 20 /0Amazwana Asho ukuthini ama-fiber optic transceivers TX kanye ne-RX, futhi uyini umehluko? I-Optical fiber transceiver iyiyunithi yokuguqula imidiya ye-Ethernet eshintshanisa amasiginali kagesi asontekile amabanga amafushane kanye namasiginali okubona amabanga amade. Ibizwa nangokuthi i-fiber converter ezindaweni eziningi. Umkhiqizo uvame ukusetshenziswa endaweni yangempela yenethiwekhi lapho ... Funda kabanzi Ngomphathi / 16 Jun 20 /0Amazwana Amaphutha ayishumi ajwayelekile kanye nezixazululo zama-optical fibre transceivers Ama-transceivers e-Fiber optic ngokuvamile asetshenziswa endaweni yangempela yenethiwekhi lapho izintambo ze-Ethernet zingakwazi ukumboza futhi kufanele zisebenzise ama-optical fibers ukwandisa ibanga lokudlulisela. Imvamisa atholakala endaweni yokufinyelela yamanethiwekhi ezindawo zedolobha elikhulu, futhi asetshenziswa kakhulu ezindaweni ezahlukahlukene ... Funda kabanzi Ngomlawuli / 12 Jun 20 /0Amazwana Uyihlukanisa kanjani inethiwekhi yokufinyelela optical OLT, ONU, ODN, ONT Inethiwekhi yokufinyelela optical inethiwekhi yokufinyelela esebenzisa ukukhanya njengendlela yokudlulisa, eshintsha izintambo zethusi, futhi isetshenziselwa ukufinyelela ikhaya ngalinye. Inethiwekhi yokufinyelela ebonakalayo ngokuvamile iqukethe izingxenye ezintathu: itheminali yomugqa optical OLT, iyunithi yenethiwekhi yokubona i-ONU, kanye nenethi yokusabalalisa optical...
