Yini okufanele ngiyenze uma izinga lokushisa lemojula ye-optical liphezulu kakhulu? Indlela yokuxazulula?
Imojuli ye-optical idivayisi yokubona ebucayi kakhulu. Uma izinga lokushisa lokusebenza lemojula ye-optical liphezulu kakhulu, lizodala izinkinga ezifana namandla okudlulisa amehlo amaningi, iphutha lesignali elitholiwe, ukulahlekelwa kwephakethe, njll., futhi kushise imodyuli ye-optical ngokuqondile ezimweni ezinzima.

Izibani ezimbalwa zemodemu yefayibha ye-Optical zivamile futhi isimo sesignali yokukhanya yemodemu ye-Optical sijwayelekile kanye nokuhlaziywa kokwehluleka.
Kunamalambu amaningi esignali kumodemu ye-fiber optic, futhi singahlulela ukuthi okokusebenza nenethiwekhi kuyiphutha yini ngokukhanya kwenkomba. Nazi ezinye izinkomba ezijwayelekile zemodemu nezincazelo zazo, sicela ubheke isingeniso esinemininingwane ngezansi. 1. Ukuze kube lula indawo...Funda kabanzi - Ngu-Admin / 28 Jul 20 /0Amazwana
Ayini amanethiwekhi okubona asebenzayo (AON) kanye ne-passive (PON)?
Yini i-AON? I-AON iyinethiwekhi ye-optical esebenzayo, ikakhulukazi yamukela ukwakhiwa kwenethiwekhi ye-point-to-point (PTP), futhi umsebenzisi ngamunye angaba nomugqa we-fiber optical ozinikele. Inethiwekhi yokubona esebenzayo isho ukuthunyelwa kwama-router, ama-switching aggregator, okokusebenza okubonakalayo okusebenzayo nezinye izisetshenziswa ezishintshayo...Funda kabanzi - Ngomphathi / 26 Jun 20 /0Amazwana
Ungayithola kanjani i-PCB enembayo ephezulu?Ungayithola kanjani i-PCB enembayo ephezulu?
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 / 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 / 09 Jun 20 /0Amazwana
Ungahlulela kanjani ukuthi kunenkinga nge-fiber optic transceiver?
Ngokuvamile, amandla akhanyayo we-fiber optical transceiver noma i-optical module kanje: i-multimode iphakathi kwe-10db ne--18db; imodi eyodwa ingu-20km phakathi kuka -8db no -15db; futhi imodi eyodwa ingu-60km iphakathi kuka -5db no -12db phakathi. Kodwa uma amandla akhanyayo ohlelo lokusebenza lwe-fiber optic transceiver...Funda kabanzi
