Hordhaca Teknolojiyadda PAM4
Kahor intaadan fahmin tignoolajiyada PAM4, waa maxay tignoolajiyada wax-ka-beddelka? Tiknoolajiyada wax-ka-beddelka waa farsamada loogu beddelo calaamadaha baasaaska (calaamadaha korantada ee ceeriin) ee calaamadaha gudbinta. Si loo hubiyo waxtarka isgaadhsiinta loogana gudbo dhibaatooyinka gudbinta ishaarada fog, waxaa lagama maarmaan ah in lagu wareejiyo spectrum spectrum kanaalka soo noqnoqda sare iyada oo loo marayo qaabaynta...Sii akhri -
Qalab badan oo shaqeynaya oo loogu talagalay isgaarsiinta fiber optic: qaabeynta iyo maareynta transceivers fiber optic
Dhinaca isgaarsiinta fiber optic-ga, transceivers fiber optic ma aha oo kaliya aaladaha muhiimka ah ee beddelka calaamadaha korantada iyo indhaha, laakiin sidoo kale aaladaha kala duwan ee aan looga maarmin dhismaha shabakadda. Maqaalkani wuxuu sahamin doonaa qaabeynta iyo maaraynta transceivers fiber optic, si loo bixiyo hagitaan wax ku ool ah maamulayaasha shabakadaha iyo injineerada. Muhiimadda o...Sii akhri -
Shanlada inta jeer ee indhaha iyo gudbinta indhaha?
Waxaan ognahay in tan iyo 1990-meeyadii, tignoolajiyada isku dhufashada ee qaybinta mawjadda dhererka WDM loo isticmaalay isku xirka fiber optic-ka fog ee boqollaal ama xitaa kumanaan kiiloomitir. Waddamada iyo gobollada intooda badan, kaabayaasha fiber optic-ga ayaa ah hantidooda ugu qaalisan, halka qiimaha agabka gudbinta uu yahay mid aad u hooseeya. Si kastaba ha ahaatee, iyadoo kororka qarxa ee heerka gudbinta xogta shabakada...Sii akhri -
EPON, GPON network broadband iyo OLT, ODN, iyo ONU tijaabada is dhexgalka shabakada saddex-geesoodka ah

Tignoolajiyada EPON waxaa habeeyey kooxda shaqada ee IEEE802.3 EFM. Bishii Juun 2004, kooxda shaqada ee IEEE802.3EFM waxay sii daayeen EPON stan...Sii akhri -
Falanqaynta faa'iidooyinka WiMAX ee gelitaanka IPTV
Tan iyo markii IPTV ay soo gashay suuqa 1999, heerka kobaca ayaa si tartiib tartiib ah u kordhay. Waxa la filayaa in isticmaaleyaasha IPTV-ga caalamiga ahi ay gaadhaan in ka badan 26 milyan marka la gaadho 2008, iyo kobaca sannadlaha ah ee isticmaaleyaasha IPTV ee Shiinaha laga bilaabo 2003 ilaa 2008 waxa uu gaadhi doonaa 245%. Marka loo eego sahanka, kiiloomitirka ugu dambeeya ee gelitaanka IPTV waxaa caadi ahaan loo isticmaalaa habka gelitaanka fiilada DSL, iyada oo la mamnuucay ...Sii akhri -
DCI-ga Caadiga ah ee Dhismaha iyo Silsiladda Warshadaha
Dhowaan, oo ay dhaqaajisay horumarinta tignoolajiyada AI ee Waqooyiga Ameerika, baahida loo qabo isku xirka shabakadaha xisaabaadka ayaa si weyn u kordhay, tignoolajiyada isku xidhan ee DCI iyo alaabada la xidhiidha ayaa soo jiidatay indhaha suuqa, gaar ahaan suuqa caasimada.

Shanlooyinka soo noqnoqda indhaha iyo gudbinta indhaha?
Sida aan ognahay, laga soo bilaabo 1990-meeyadii, tignoolajiyada WDM WDM waxaa loo istcimaali jiray xiriirinta fibre-optic-ga dheer ee boqollaal ama xitaa kumanaan kiiloomitir. Inta badan gobolada dalka, kaabayaasha fiber-ka ayaa ah hantida ugu qaalisan, halka qiimaha agabka wareejinta uu yahay mid aad u hooseeya. Si kastaba ha ahaatee, iyadoo qaraxa heerka xogta ee shabakadaha sida 5G, tignoolajiyada WDM ayaa noqonaysa mid sii kordheysa oo muhiim ah...Sii akhri -
Waa maxay shuruudaha gaarka ah ee fiilooyinka Profinet?
Profinet waa hab-raaca isgaadhsiinta warshadaha ee ku salaysan Ethernet, oo si weyn loogu isticmaalo nidaamyada xakamaynta otomaatiga, Sharuudaha gaarka ah ee fiilada Profinet ayaa inta badan diirada lagu saaraa sifooyinka jireed, waxqabadka korantada, la qabsiga deegaanka iyo shuruudaha rakibaadda.
