Ngokuthuthuka kwemboni yezokuxhumana kanye nokwaziswa komnotho wezwe, imakethe yokushintshashintsha kwenethiwekhi yendandatho ephethwe ikhule kancane kancane. Ibiza kakhulu, iguquguquka kakhulu, ilula futhi kulula ukuyisebenzisa. Ubuchwepheshe be-Ethernet h...

Umsebenzi we-fiber optic transceivers ukuguqula phakathi kwamasignali optical kanye namasignali kagesi. Isignali yokubona okokufaka okuvela ku-optical port, futhi isignali kagesi iphuma embobeni kagesi, futhi ngokuphambene nalokho. Inqubo icishe ifane ne...

Iyini i-IEEE 802.3? I-IEEE 802.3 iyiqembu elisebenzayo elabhala isethi evamile ye-Institute of Electrical and Electronics Engineers (IEEE), echaza isilawuli sokufinyelela okumaphakathi (MAC) kuzo zombili izendlalelo zesixhumanisi esibonakalayo nedatha ye-Ethernet enezintambo. Lokhu kuvame uku...

I-Optical fiber transceiver iyithuluzi elibiza kakhulu futhi elivumelana nezimo. Ukusetshenziswa okuvamile ukuguqula amasignali kagesi ngamapheya asontekile abe amasignali okubona. Ngokuvamile isetshenziswa ezintambo zethusi ze-Ethernet ezingakwazi ukumbozwa futhi kufanele zisebenzise imicu yokubona ukuze ...

Kuyini ukudayiswa kwenethiwekhi ye-Ring? Inethiwekhi yokukhala isebenzisa indandatho eqhubekayo ukuxhuma idivayisi ngayinye ndawonye. Iqinisekisa ukuthi isignali ethunyelwe idivayisi eyodwa ingabonwa yiwo wonke amanye amadivaysi eringini. Ukungadingeki kwenethiwekhi yeringi kubhekise ekutheni ingabe iwindi lisekela...

Iyini i-Network Topology Network topology ibhekisela ezicini zesakhiwo esibonakalayo njengokuxhumeka okungokoqobo kwemidiya ehlukahlukene yokudlulisa, izintambo zenethiwekhi, futhi idingida abstract ngokusebenzisana kwamaphoyinti ahlukahlukene ohlelweni lwenethiwekhi ngokuboleka ...

Iyini i-STP? I-STP (I-Spanning Tree Protocol ) iphrothokholi yokuxhumana esebenza kungqimba lwesibili (ungqimba lwesixhumanisi sedatha) kumodeli yenethiwekhi ye-OSI. Ukusetshenziswa kwayo okuyisisekelo ukuvimbela izihibe ezibangelwa izixhumanisi ezingasasebenzi kumaswishi. Isetshenziselwa ukuqinisekisa ukuthi kukhona ...

Siyini isiphepho sokusakaza? Isiphepho sokusakaza sisho nje ukuthi lapho idatha yokusakaza ikhukhula inethiwekhi futhi ayikwazi ukucutshungulwa, ithatha inani elikhulu lomkhawulokudonsa wenethiwekhi, okuholela ekungakwazini kwezinsizakalo ezijwayelekile ukusebenza, noma ngisho nokukhubazeka okuphelele ...

I-Optical fibre transceiver iyiyunithi yokuguqula imidiya ye-Ethernet eshintshanisa amasiginali kagesi asontekile amabanga amade kanye namasiginali okubona amabanga amade. Ibizwa nangokuthi i-fiber converter ezindaweni eziningi. Umkhiqizo ngokuvamile usetshenziswa ku...

(1) Umkhawulokudonsa ophezulu ongakaze ubonwe. Izinga le-GPON liphezulu njenge-2.5 Gbps, elingahlinzeka ngomkhawulokudonsa omkhulu ngokwanele ukuhlangabezana nesidingo esikhulayo somkhawulokudonsa ophezulu kumanethiwekhi azayo, futhi izici zayo ze-asymmetric zingavumelana kangcono nedatha ye-broadband se...
