Ngowe-1970 kwaqala ukwakhiwa imigca fibre-optic inkampani Corning, zibonakaliswa ekuqaleni ishishini elitsha. Namhlanje, uphuhliso lobuchwepheshe fibre-optic ngaphambi amanye amacandelo koqoqosho lwehlabathi, ukwanda komthamo woyekelelo ifayibha nge-40% ngonyaka ngamnye! umbhekisi phambili Main kunye welayisensi ubuchwepheshe - United States - kwiminyaka yakutshanje, yavelisa million 10 eekhilomitha ifayibha enombala, nto leyo ilingana 250 enesiqu umhlaba kwi-ikhweyitha. imigca unxibelelwano fibre-optic - ndlela ifanelekileyo ulwazi lonaniso. nempahla yabo - kokwaba umqondiso kwizigidi abathengi - ayikho enye indlela. Bafana imithambo idlulisela imiyalezo phakathi amazwekazi, emazweni, zamisa kulo, phakathi komzi, inkampani, ngokwakha ubuhlobo fibre optic (abazo).
iiseli zabo esebenzayo ukuguqula, uhlobo, ikhulise uphawu ukukhanya ngesondo. Nantsi ke. Umthombo radiation inonamathelwano monochromatic i laser. Modulators ukudala iliza ukukhanya, ngokulandelelana, isakhiwo ezahlukeneyo uphawu lukagesi igalelo. Multiplexers uwahlule sihlanganise nemiqondiso. Regenerators kuncitshiswa Ipharamitha ukubetha optical. Le photodetector uvelisa inguqu ngokubaxwa: light - umbane. imigca unxibelelwano fibre-optic banamalungelo ezibalulekileyo: lula ukufaka ngokusebenzisa yemiqadi yokuhlanganisa, akwazi ukuba adlulisele uphawu ukukhanya phantse akukho ilahleko, ngokuthembekileyo ukukhusela ulwazi.
Phakathi imigca zehlabathi unxibelelwano fibre-optic ezi Intambo kakhulu ezininzi. Bona uxhumane Europe kunye eUnited States naseKhanada. Le inkulu ngobude - Transpacific, bazisa kunye ne-United States kunye iJapan, China, South Korea, Hong Kong, Hawaii. Ukubeka imigca fibre-optic ikhutshwa phandle ziinkundla ezikhethekileyo. Russia ibandakanyeka kwiiprojekthi efanayo. Kunyaka ophelileyo waqala ukwakhiwa kumgca wokujoyina ena, Sakhalin kunye Magadan. Qaphela ukuba kusetyenziswa ubungakanani ifayibha core / esingxotyeni for buti fibre optic - 1,3-1,55 mm.
State ebalulekileyo yengingqi fibre optic unxibelelwano phakathi embindini kunye nakwimimandla ngaphakathi mizi. Baya kwenza ifayibha ithambeka - 50/125 microns. amashishini ezinkulu basebenzisa imigca fibre-optic unxibelelwano ukuba ukuphuculwa kolawulo phezu umfuziselo "ofisi yekhompyutha", kwakunye - kuba matshini kwimveliso. Akumangalisi ukuba kumazwe aphuhlileyo (phakathi kwabo - Japan, eNgilani, Italy, France) ekwakhiweni kukho ifayibha enombala isetyenziswa kuphela. kwinqanaba lommandla uhambelana kwisantya kokuba ezincinane ilahleko factor, monomode intambo. Isisombululo Enterprise Akubizi kakhulu kwaye kulula entabeni multimode USB. ifayibha Optical sisetyenziswe zincwadi Womenzi lobushushu, uxinzelelo kunye ombane. Yena zisetyenziswa hydrophones, sonar, ngezakhi, navigation. Used in iinkqubo zokhuseleko, alarm.
Ngamafuphi, simele senze uxinzelelo ubhalo kwinto yokuba obu bugcisa nangoku kude ediniwe ngokwawo, ukuba kwi yee-point yophuhliso lwayo. Ukukhokela inkampani mveliso Sisco, 3COM, D-LINK, uDell, Allied TELESYN uphuculo ngamandla iimveliso optoelectronic. multimode ezintsha (iteknoloji ezitshiphu) ifayibha enombala ngcono iimpawu. Lo Endliwa izihlanganisi okubonakalayo kunye nemigangatho yokuvelisa lula (izenzo ziquka ngqo phantsi micron). Ukuze kangcono nokudlulisela signal liphuhlise ezintsha Planar ode laser, babonelelwa resonator nkqo. Ukuqhuba uphando entsimini kweenkqubo iingcingo ezihamab phantsi wakhiwe.
