Indlela yokufikelela kunye nokulawula izixhobo ezahlukeneyo zekhompyuter ngokusebenzisa imidiya kwi-LAN iqondwa ngolu hlobo lulandelayo. Kwakudala, i-Ethernet yayisetyenziselwa ukudibanisa yonke imigca yeekhompyuter zekhaya kwibhasi ukuqonda unxibelelwano oludibeneyo lweekhompyuter. Xa usebenzisa le ndlela yokuthumela idatha, kufuneka...

1、 Ubushushu bokusebenza Ubushushu bokusebenza bemodyuli yokubona. Apha, iqondo lobushushu libhekisa kubushushu bendlu. Kukho amaqondo okushisa amathathu okusebenza kwemodyuli ye-optical, ukushisa kwezorhwebo: 0-70 ℃; Ubushushu bemizi-mveliso: – 40 ℃ – 85 ℃; Kukho kwakhona i-exp ...

I-Diode yenziwe nge-PN junction, kwaye i-photodiode inokuguqula isignali ye-optical ibe ngumqondiso wombane, njengoko kuboniswe ngezantsi: Ngokuqhelekileyo, i-covalent bond i-ionized xa i-PN junction ikhanya ngokukhanya. Oku kudala imingxunya kunye neeperi electron. Ifotocurrent yenziwe ngenxa...

I-LAN yeyona nto idumileyo siyisebenzisa namhlanje. Yintoni iLAN? Inethiwekhi yeNdawo yeNgingqi (LAN) ibhekisa kwiqela leekhompyuter ezidityaniswe ziikhompyuter ezininzi kwindawo ethile zisebenzisa ijelo losasazo. Okukhona kukho kule ndawo, kokukhona izixhobo ezikwaziyo ukunxibelelana omnye komnye. Kwaye kuphela ...

Ngophuhliso olukhawulezayo lweekhompyuter kunye nethekhnoloji yokunxibelelana kwabo (eyaziwa nangokuthi "iteknoloji yenethiwekhi"), i-Ethernet ibe yinethiwekhi yekhompyuter enemigangatho emibini enenqanaba eliphezulu lokungena ukuza kuthi ga ngoku. Inxalenye ephambili ye-Ethernet sisitshixo se-Ethernet. Incwadi kunye...

I-VCSEL, ebizwa ngokuba yi-Vertical Cavity Surface Emitting Laser ngokupheleleyo, luhlobo lwe-laser semiconductor. Okwangoku, uninzi lwe-VCSEL lusekwe kwii-semiconductors ze-GaAs, kwaye i-wavelength ekhutshwayo ikakhulu kwi-infrared wave band. Ngo-1977, uNjingalwazi u-Ika Kenichi weYunivesithi yaseTokyo yeTekhnoloji ufir...
