Ushwankathelo lwemarike yentambo yonxibelelwano

Imarike yonxibelelwano kunye nedatha yentambo kulindeleke ukuba ikhule ukusuka kwi-19.18 yeebhiliyoni zeedola ngo-2022 ukuya kwi-45.37 yeebhiliyoni zeedola ngo-2032, ngesantya sokukhula sonyaka (CAGR) se-8.51% ngexesha loqikelelo. Ngokwenqanaba lamva nje locingo lwehlabathi kunye nabavelisi bentambo abakhutshwe ngumbutho woshishino we-APC, Amashishini aseTshayina athatha i-11 kwangama-20 aphezulu emhlabeni jikelele abavelisi bentambo kunye neentambo ngo-2021., ebonisa ukuba ukhuphiswano lwamazwe ngamazwe lwamashishini aseTshayina luye lwaphucuka.

Umzi-mveliso wengcingo kunye neentambo, ulandela ishishini leemoto, lishishini lesibini ngobukhulu e-China, kunye nesantya sokwaneliseka kwemveliso engaphezulu kwe-90%. Iyonke imveliso yocingo kunye nentambo yaseTshayina igqithile kwelo lase-United States kwihlabathi jikelele. Yiyo loo nto, iTshayina ibe lelona hlabathi livelisa iingcingo kunye neentambo. 

Njengoko ishishini lamandla laseTshayina likhula ngokuqhubekayo, imfuno yocingo kunye nentambo nayo iya kunyuka ngokukhawuleza. Oku kuthetha ukuba amandla ophuhliso lwexesha elizayo kwishishini locingo kunye nentambo likhulu.

Ukuqonda iintambo zonxibelelwano

Iintambo zonxibelelwano zidlala indima ebalulekileyo ekudluliseni idatha, kwaye ezinye iiparitha ezisisiseko ziya kuchazwa ngokweenkcukacha ngezantsi. Unokufunda ngakumbi malunga nemveliso ngokusebenzisa ezi parameters.

1. iiparamitha zokusebenza zothumelo

Ububanzi bebhendi: ibhekisa kuluhlu lwamaza ombane apho intambo inokuhambisa umqondiso ngempumelelo, ngokwesiqhelo eHertz (Hz). I-bandwidth enkulu, iphezulu inani kunye nesantya sedatha enokuthi idluliselwe.

Ukucocwa: Xa isignali ihanjiswa kwikhebula, kukho ukulahlekelwa kwamandla, kwaye ukutshatyalaliswa kubonisa iqondo lokunciphisa umqondiso ngexesha lokudluliselwa, okuqhelekileyo kulinganiswa ngama-decibels / ubude beeyunithi (dB / m okanye dB / km).

Crosstalk: Ukuphazamiseka okufanayo kwemiqondiso phakathi kwemigca ekufutshane, edla ngokubonakaliswa ngeedecibels. I-crosstalk eninzi kakhulu iya kuchaphazela umgangatho kunye nokuchaneka komqondiso.

Umqondiso ukuya kwingxolo: Umlinganiselo wamandla omqondiso kumandla wengxolo kwiidecibels. Iphezulu i-SNR, ingcono umgangatho wesignali.

2. Iiparamitha zombane

Ukuphazamiseka kophawu: Ukuchasana kweempawu zekhebula kwi-current, ngokuqhelekileyo ixabiso elimiselweyo, njenge-50 ohms, i-75 ohms, njl.

4. Ukuhlelwa ngokwendlela yokubeka

Iintambo zonxibelelwano nazo zineendlela ezahlukeneyo zokubeka ezifana ne-overhead, umngcwabo othe ngqo, umbhobho, kunye nangaphantsi kwamanzi ukuze zivumelane neemeko kunye neemfuno ezahlukeneyo.

Imingeni kushishino lweentambo zonxibelelwano

Ishishini leentambo zonxibelelwano nalo liye ladibana nothotho lweengxaki ebezifuna ukusonjululwa. 

Okokuqala, Ukuphazamiseka kwe-electromagnetic kunye neengxaki zokuthomalalisa umqondiso ayinakungahoywa. Ngexesha lokusebenza kwezixhobo zombane ezinjengeenqanawa kunye neenkqubo zamandla, ukuphazamiseka kwe-electromagnetic kuya kuchaphazela kakhulu umgangatho wokuhanjiswa komqondiso weentambo zonxibelelwano.

Ngokwedatha, phantse i-10% yokusilela kunxibelelwano lweenqanawa kubangelwa kukuphazamiseka kombane. Akunjalo kuphela oku kubangela ukunciphisa umgangatho wokuhanjiswa kwesignali, oku kunokukhokelela ekuphazamisekeni konxibelelwano okanye ukulahleka kwedatha, kodwa kwandisa iindleko zokugcinwa kwenkqubo kunye nokulungiswa kunye nokunciphisa ukusebenza ngokubanzi. 

Okwesibini, umgangatho wezinto eziphathekayo yenye ingxaki enzulu. Ukuba kusetyenziswa izinto ezikumgangatho ophantsi we-cable optical cable, oku kunokukhokelela ngokulula ekuphuhlisweni kwentambo ye-optical, ukuhanjiswa kwesignali embi, kunye nezinye iingxaki, kungekuphela nje ukunyusa izinga lokungaphumeleli kwentambo ye-optical cable kunye nokuchaphazela uzinzo kunye nokuthembeka kwenkqubo yonxibelelwano kodwa nokwandisa ukutshintshwa kunye nokugcinwa rhoqo kwentambo ye-optical, ukwandisa iindleko.

Iingcebiso zokukhetha

Le bhlog ijolise ekuncedeni ababoneleli baqonde ukubaluleka kunye nobunzima beentambo zonxibelelwano ukwenza izigqibo zokuthenga ezinolwazi.

Ukwenza oku, okokuqala, umntu kufuneka acacise iimfuno ezipheleleyo:
