Izinga eliphezulu lamamojula wesigaba VI yi-eia/tia 568b 2-1. Amapharamitha abaluleke kakhulu ukulahlekelwa kokufaka, ukulahlekelwa kokubuyisela, i-crosstalk eseduze, njll.

Faka ukulahlekelwa: ngenxa yokuba khona kwe-impedance yesiteshi sokudlulisela, kuzokwandisa ukuncishiswa kwezingxenye ze-high-frequency yesiginali njengoba imvamisa yesignali ikhula. I-attenuation ayihlobene kuphela nemvamisa yesignali, kodwa futhi ihlobene nebanga lokudlulisela. Njengoba ubude bukhula, incwadi
Ukuncishiswa kwesignali nakho kuyanda. Ikalwa ngenani lokulahlekelwa kwesignali eduze kwesiteshi sokudlulisela ngobude beyunithi, futhi imele isilinganiso samandla esignali ukusuka kusithumeli somthombo kuya kumamukeli.

Ukulahlekelwa kokubuyisela: ngenxa yoshintsho lwe-impedance kumkhiqizo, i-oscillation yendawo izokwenzeka, okuholela ekubonakalisweni kwesignali. Ingxenye yamandla eboniswa kusidlulisi izodala umsindo, okuholela ekuhlanekezelekeni kwesignali kanye nokuncipha kokusebenza kokudlulisela. Okufana ne-duplex kilo egcwele
I-Megagrid izophutha isignali ebonisiwe yesiginali eyamukelwe, ibangele ukushintshashintsha kwamasignali awusizo futhi ibangele ukudideka. Amandla angabonisiwe kancane asho ukuthi ukungaguquguquki kwemigqa esetshenziswe esiteshini kungcono, isignali yokudlulisela iphelele kakhulu, futhi umsindo omncane usesiteshini. enanela
Ifomula yokubala yokulahlekelwa RL: ukulahlekelwa kokubuyisela = isignali edlulisiwe ÷ isignali ebonisiwe.
Eklanyweni, indlela yokuxazulula ukwehluleka kwepharamitha yokulahlekelwa ukubuyisela ukuqinisekisa ukuhambisana okuphelele komugqa we-impedance kanye nokubambisana nezinhlobo eziyisithupha zezintambo ezine-impedance engu-100 ohm.
Isibonelo, ibanga le-interlayer elingalingani le-PCB, ukuguqulwa kwesigaba esiphambanayo solayini wethusi wokudlulisa, nokungafani phakathi kwamakhondatha kumojuli nezinhlobo eziyisithupha zamakhondatha ekhebula kuzobangela ukuthi imingcele yokulahlekelwa kokubuyisela ishintshe.

I- Near end crosstalk (okulandelayo): okulandelayo ibhekisela ekuhlanganisweni kwesignali phakathi kwepheya eyodwa yemigqa nenye ipheya yemigqa kupheya yemigqa yokudlulisela, okungukuthi, lapho ipheya eyodwa yolayini ithumela isignali, isignali etholwe kwenye ipheya yolayini eseduze. Lesi siginali ye-crosstalk ikakhulukazi ingenxa yokuba seduze
Kuhlanganiswe amandla noma inductance.
