Dhata uye Network

Isu tinokupa iwe pane-saiti kuongororwa pamwe pazasi bvunzo chero mupi wako wekutengesa aine akakwana uye akasarudzika akaedzwa testers anowanikwa kuyedza akakosha mhando mapoinzi:
   
Pinout / Kuenderera mberi: Kuedzwa kwekuenderera kana kuramba kuenderera kunoreva iyo inoenderera nzira yekuyerera kwazvino mudunhu yakavharwa. Kuenderera kwekuyedza kuchakubvumidza iwe kuyedza kana magetsi emagetsi achigona kuyerera pakati pemapoinzi maviri.

Kuramba Tester: Uku ndiko kuyerwa kwekushora kwa conductor kune elektrononi yazvino, ino kuyerwa mu ohms. Kana paine kuramba kuripo, ikozvino kugona kuchaderera sezvo hurefu hwetambo huchiwedzera. Izvi zvinoreva kuti iyo yakareba tambo, iko kushomeka kwazvino kugona kwainayo. Mazhinji maongorori ehunyanzvi anokwanisa kuyera ohms uye anogona kuverenga kuramba.

Kuisa Kurasikirwa: Izvi zvinowanzozivikanwa sekurasikirwa kwesimba muchiratidzo chekudzoka kana mudziyo ukaiswa pasi iine fiber fiber mutsetse. Kana chiratidzo chinotapuriranwa chikaoneswa nechinhu chinobatanidza, izvi zvinokonzeresa kurasikirwa.

NEXT: Ichi chirevo chinomiririra "padhuze-kuguma crosstalk", kunova kukundikana kana kupindira pakati pewaya mbiri mukati mekambo. Izvi zvinogona kuitika kana tambo dzakapetwa peya tambo dzinoyambuka. Kuvhiringidzika ndiko kuyerwa kwekukanganisa kunokonzerwa nekaviri kakamonyaniswa kana vaviri vane wired vayambuka. Kuedzwa kweINOTEVERA kunogona kudonha kana vamwe vaviri vari mukati mekambo vachipfuura, uye vamwe vanokundikana, zvichikonzera kuti iwe uedze imwe neimwe waya zvakasiyana.

PS INOTEVERA: "Power-sum padhuze nekumucheto crosstalk chiyero uye kuwedzerwa kweINOTEVERA sezvo ichishanda kumagumo kwetambo ina dzakakombama tambo mbiri.

ACR-F: "Kugadziriswa kune crosstalk ratio - kure kumagumo" Inoona kuti yakakomberedzwa peya tambo inogamuchira chiratidzo kumagumo ekugashira tambo, kuve nechokwadi kuti hapana kumwe kupindirana kubva kune imwe tambo tambo mbiri. ACR-F inoyerwa neve network testers muma decibel. Weti network tester inokwanisa kuverenga simba remasaini rakafambiswa mugumo rimwe rekubatanidza kwevakamonyanisa vaviri.

PS ACR-F: "Power Sum Attenuation-to-Crosstalk-Far End": Musiyano uripo pakati pePSNEXT nekudzikisira pamagumo ekupedzisira etambo. PS ACR-F inoverenga huwandu hwemagetsi hwevamwe vaviri ACR-F.

ACR-N: "Kugadziriswa kuCrosstalk Ratio -Near End": Ichi ndicho chiyero chinotaurira kana kufambiswa kwemasaini kwakasimba kudarika kupindira kunokonzerwa necrosstalk panoperera tambo.

PS ACR-N: Izvi zvinomiririra Power Sum Attenuation-to Crosstalk-Near End uye inotsanangura huwandu hwesimba ndiko kuunganidzwa kwekuderedzwa mukati memawaya mana.

Dzorera Kurasikirwa: Izvi zvinoitika kana tambo ikawana zvidiki zvemukati mamakiji anokonzerwa nemafungidziro anotumirwa kumashure kune anotepfenyura achiri munzira kune anogamuchira. Kudzoka kurasikirwa kunowanzoitika mumataipi ane subpar terminations nekuda kwe shoddy crimping. Pamusoro pekukonzeresa kutapudza kwemasaini, kana huwandu hwekurasikirwa netambo hwanyanya, izvi zvinogona kukonzera kuti tambo igamuchire giredhi rinotadza kana yaedzwa. Dzosera kurasikirwa bvunzo dzinoyerwa muma decibel. Iyo equation yekudzoka kurasikirwa kweKati 5e tambo chiteshi ndeye: RL = 10 log10 (Pout / Pin) Iyo frequency (muMHz) 1 <f <20 yakaenzana chikamu 5e (dB) 17. 20

Packet Kurasikirwa / Crosstalk
Paunogamuchira kupindira uye chiratidzo chisingadiwe mukati mekambo yako, iwe une izvo zvinonzi secrosstalk. Zvirwere izvi zvinofambidzana neizvo zvinozivikanwa sekurasikirwa kwepaketi, izvo zvinogona kudzikisira data uye kuputsa simba rechiratidzo. Idzi nyaya mbiri dzinogona kukanganisa netiweki yako, asi nerombo rakanaka inogona kuyedzwa neineti tester iyo ine bvunzo manejimendi software yakaiswa.

Kuenderera mberi uye Vanoongorora Vazvino
Kana iwe uchida kuyedza voltage, yazvino kana kuenderera, iwe unogona kuzviita neye muyedzo wemagetsi. Rudzi urwu rwemuedzo runokutendera kuti uedze tambo uchishandisa volts, yazvino, kana ohms uchiongorora mabudura edunhu mukati mekambo. MaTesters anogona otomatiki kuyera AC / DC volts uye zvazvino manhamba, kazhinji mukati menyaya masekondi.

Tone jenareta Vanoedza
Tone jenareta kazhinji anouya neaplaya yekuwedzera uye anogona kuyedza kuenderera kwetambo achishandisa odhiyo nekutumira toni pasi paboka rewaya apo gudzazwi rinogamuchira toni iyoyo uye inosarudzira waya dzakakanganisika mukati memaviri akapoteredzwa. Tone jenareta anogona kutarisa mashandiro emachiteshi, tarisa nyaya pamagumo etambo uye anogona kunyange kuisazve nzvimbo dzisina kushandiswa.
