Maitiro ekuwana nekudzora akasiyana komputa zvishandiso kuburikidza ne media muLAN inofanonzwisiswa sezvinotevera. Kare kare, Ethernet yaishandiswa kubatanidza mitsara yese yemakomputa epamba kubhazi kuona kutaurirana kwemakomputa. Paunenge uchishandisa nzira iyi kutumira data, unofanirwa...

1、 Kushanda tembiricha Kushanda tembiricha ye optical module. Pano, tembiricha inoreva tembiricha yedzimba. Kune matatu ekushanda tembiricha ye optical module, tembiricha yekutengesa: 0-70 ℃; Kupisa kwemaindasitiri: -40 ℃ - 85 ℃; Kune zvakare exp ...

Iyo Diode inoumbwa nePN junction, uye iyo photodiode inogona kushandura chiratidzo che optical muchiratidzo chemagetsi, sezvinoratidzwa pasi apa: Kazhinji, covalent bond inoiswa ionized apo PN junction inovhenekera nechiedza. Izvi zvinogadzira maburi uye ma electron pairs. Iyo photocurrent inogadzirwa nekuda kwe ...

LAN ndiyo inonyanya kufarirwa yatinoshandisa nhasi. Chii chinonzi LAN? A Local Area Network (LAN) inoreva boka remakomputa akabatanidzwa nemakomputa akawanda mune imwe nzvimbo achishandisa chiteshi chenhepfenyuro. Iyo yakawanda iripo munzvimbo ino, iyo yakawanda michina inogona kutaurirana kune mumwe nemumwe. Uye chete ...

Nekukurumidza kusimukira kwemakomputa uye tekinoroji yavo yekubatanidza (inozivikanwawo se "network tekinoroji"), Ethernet yave iyo pfupi-yakapetwa maviri-layer komputa network ine yakanyanya kupinza mwero kusvika parizvino. Iyo yakakosha chikamu cheEthernet ndiyo Ethernet switch. Manual uye...

VCSEL, iyo inonzi Vertical Cavity Surface Emitting Laser yakazara, imhando ye semiconductor laser. Parizvino, maVCSEL mazhinji akavakirwa paGaAs semiconductors, uye emission wavelength inonyanya muinfrared wave band. Muna 1977, Muzvinafundo Ika Kenichi weTokyo University of Technology fir...
