Umehluko phakathi kwe-optical transceiver, optical fibre transceiver kanye nemodemu yokubona
Namuhla, kumaphrojekthi wokuxhumana wenethiwekhi yamanje, ama-transceivers optical, ama-transceivers optical fiber, namamodemu optical angathiwa asetshenziswa kabanzi futhi ahlonishwa kakhulu ngabasebenzi bezokuphepha. Ngakho-ke, ingabe uyawazi umehluko phakathi kwalezi zintathu Ezicacile? Imodemu ye-Optical iwuhlobo lwezisetshenziswa...Funda kabanzi - Ngomphathi / 12 Oct 20 /0Amazwana
Uyini umehluko phakathi kwama-transceivers optical wemodi eyodwa yemodi eyodwa kanye nemodi eyodwa?
I-Optical fiber transceiver iyiyunithi yokuguqula imidiya ye-Ethernet eshintshanisa amasiginali kagesi asontekile amabanga amafushane kanye namasiginali okubona amabanga amade. Ngokwezidingo zayo, ihlukaniswe kakhulu ngama-transceiver optical we-fiber eyodwa kanye nama-transceiver optical we-dual-fiber.Okulandelayo...Funda kabanzi - Ngomlawuli / 29 Sep 20 /0Amazwana
Funda ngefayibha, i-fiber yemodi eyodwa, kanye nefayibha yemodi eminingi ngomzuzu owodwa
Isakhiwo esiyisisekelo se-fiber optical I-fiber engenalutho ye-fiber optical ivame ukuhlukaniswa zibe izingqimba ezintathu: i-core, i-cladding ne-coating. I-fiber core kanye ne-cladding yakhiwe ngengilazi enezinkomba ezihlukile ze-refractive, isikhungo siwumgogodla wengilazi we-refractive high (silica ye-germanium-doped), a...Funda kabanzi - Ngomlawuli / 23 Sep 20 /0Amazwana
Isicelo kanye nomehluko phakathi kwe-EPON ne-GPON
1.I-PON Isingeniso (1) Iyini ubuchwepheshe be-PON PON (inethiwekhi ye-passive optical) (okuhlanganisa i-EPON, i-GPON) ubuchwepheshe obuyinhloko bokuqalisa bokuthuthukiswa kwe-FTTx (i-fiber eya ekhaya). Ingagcina izinsiza ze-fiber yomgogodla kanye namazinga enethiwekhi, futhi ingahlinzeka ngamakhono omkhawulokudonsa wezindlela ezimbili ...Funda kabanzi - Ngomlawuli / 19 Sep 20 /0Amazwana
Isifinyezo sesu lokuthenga i-fiber optical transceiver kanye nendlela yokulungisa iphutha
Ukusetshenziswa kwama-transceiver fiber optical kumaphrojekthi amanje abuthakathaka kuvame kakhulu, ngakho-ke sikhetha kanjani ama-transceiver optical fiber kumaphrojekthi wobunjiniyela? Uma i-fiber optic transceiver yehluleka, ungayigcina kanjani? 1.Iyini i-fiber optic transceiver? I-optical fiber transceiver ibizwa nangokuthi i-ph...Funda kabanzi - Ngomlawuli / 15 Sep 20 /0Amazwana
Iyini iswishi ye-PoE enikwe amandla yinethiwekhi?
Ngaphambi kokuqonda ukushintshwa kwe-PoE, kufanele siqale siqonde ukuthi iyini i-PoE. I-PoE iwumthombo wamandla ngaphezu kobuchwepheshe be-Ethernet. Kuyindlela yokunikeza amandla ukude kumadivayisi enethiwekhi axhunyiwe (njenge-Wireless LAN AP, Ucingo lwe-IP, i-Bluetooth AP, Ikhamera ye-IP, njll.) kukhebuli yedatha ye-Ethernet ejwayelekile, i-el...Funda kabanzi
