Ngomphathi / 05 Nov 19 /0Amazwana Ukuthuthukiswa kwemojula yokuxhumana okungenantambo, kusukela ku-2G-3G-4G-5G Ukuthuthukiswa kwemojula yokuxhumana engenantambo: inethiwekhi ye-5G, i-25G / 100G imojula ye-optical iwumkhuba. Ekuqaleni kuka-2000, amanethiwekhi e-2G kanye ne-2.5G ayesakhiwa. Uxhumano lwesiteshi sesisekelo lwaqala ukusika kusukela kukhebula lethusi kuya kukhebula le-optical. I-1.25G SFP optical module yayi...

Ibanga lokudlulisela le-fiber yemodi eyodwa: Ukudluliswa kwesiteshi esingu-64 se-40G Ethernet kungaba ubude obungamamayela angu-2,840 kukhebula yemodi eyodwa. I-fiber yemodi eyodwa ngokuyinhloko yakhiwe indikimba, isendlalelo sokugquma kanye nesendlalelo sokumboza.Umongo wenziwe ngezinto ezibonisa ngale kakhulu.I-cladding ine-r... Funda kabanzi Ngomphathi / 25 Oct 19 /0Amazwana Izinto ezimbili ezibalulekile zokusebenzisa amamojula optical Qaphela ukuthi amaphuzu amabili alandelayo angakusiza ukunciphisa ukulahlekelwa kwe-module optical futhi uthuthukise ukusebenza kwe-optical module. Qaphela 1: Kunamadivayisi e-CMOS kule chip, ngakho-ke qaphela ukuvimbela ugesi omile ngesikhathi sokuhamba nokusebenzisa. Idivayisi kufanele ibekwe phansi kahle ... Funda kabanzi Ngomphathi / 23 Oct 19 /0Amazwana Ulwazi lwe-Optical module Okokuqala, ulwazi oluyisisekelo lwemojula ye-optical 1.Incazelo: Imojula ye-Optical: okungukuthi, imodyuli ye-optical transceiver. I-2.Isakhiwo: I-module ye-transceiver optical yenziwe idivayisi ye-optoelectronic, isifunda esisebenzayo nesixhumi esibonakalayo se-optical, futhi idivayisi ye-optoelectronic ihlanganisa ama-pa... Funda kabanzi Ngomlawuli / 22 Oct 19 /0Amazwana Iyini i-GPON? Isingeniso kuzici zobuchwepheshe be-GPON. Iyini i-GPON? Ubuchwepheshe be-GPON (Gigabit-Capable PON) yisizukulwane sakamuva se-broadband passive optical integrated access standard based on ITU-TG.984.x standard. Inezinzuzo eziningi ezifana nomkhawulokudonsa ophezulu, ukusebenza kahle okuphezulu, ukumboza okukhulu, ukusebenzelana komsebenzisi okucebile, njll. Iningi lama-opharetha liyibheka njenge... Funda kabanzi Ngu-Admin / 19 Oct 19 /0Amazwana Ubuchwepheshe obunemininingwane ye-EPON Okokuqala, iyiphi inkinga i-PON esetshenziselwa ukuyixazulula? ● Ngokuvela kwezinsizakalo zomkhawulokudonsa ophezulu ezifana nevidiyo efunwayo, imidlalo ye-inthanethi ne-IPTV, abasebenzisi banesidingo esiphuthumayo sokwandisa umkhawulokudonsa wokufinyelela.Izindlela ezikhona zokufinyelela i-Broadband ezisekelwe ku-ADSL ziya ngokuya ziba nzima ukuhlangabezana nezimfuneko zabasebenzisi f...
