Optical fiber ndi njira yamawaya yotumizira ma siginecha a kuwala.
Timatcha zizindikiro zosafunikira zamagetsi mumsewu "phokoso Phokoso mu njira yolankhulirana limayikidwa pamwamba pa chizindikirocho.Pamene palibe chizindikiro chotumizira, palinso phokoso mu njira yolumikizirana.“Phokosonthawi zonse imakhalapo mu njira yolumikizirana.Phokoso limatha kuwonedwa ngati kusokoneza kwa tchanelo, komwe kumadziwikanso kuti kusokoneza kowonjezera chifukwa kumayikidwa pamwamba pa siginecha.Phokoso ndi loopsa potumiza uthenga.Ikhoza kusokoneza chizindikiro cha analogi, kusokoneza chizindikiro cha digito, ndi kuchepetsa mlingo umene chidziwitso chingatumizidwe.
Malinga ndigwero gulu, phokoso likhoza kugawidwamagulu awiri: phokoso lopangidwa ndi anthu komanso phokoso lachilengedwe.Phokoso lochita kupanga limapangidwa ndi zochitika za anthu, monga zoyaka zamagetsi zomwe zimayambitsidwa ndi kubowola kwamagetsi ndi kusintha kwamagetsi, zoyaka zamagetsi zopangidwa ndi makina oyatsira magalimoto, kusokonezedwa ndi nyali za fulorosenti, ndi ma radiation a electromagnetic wave opangidwa ndi ma wayilesi ena ndi zida zapakhomo.Phokoso lachilengedwe ndi mitundu yosiyanasiyana ya ma radiation a electromagnetic wave m'chilengedwe, monga mphezi, phokoso lamlengalenga, ndi phokoso la cosmic kuchokera kudzuwa ndi mlalang'amba Kuphatikiza apo, pali phokoso lofunika kwambiri lachilengedwe, lomwe ndi, phokoso lotentha Phokoso la kutentha limachokera kumayendedwe otentha. ma elekitironi mu zigawo zonse resistive.Mwachitsanzo, mawaya, resistors, ndi zida za semiconductor zonse zimapanga phokoso lotentha.
Chifukwa chake, phokoso lamafuta limapezeka paliponse ndipo limakhalapo pazida zonse zamagetsi pokhapokha ngati zida zili pamagetsi.kutentha kwa thermodynamicya OK M'zigawo zodzitetezera, ma electron aulere amayenda nthawi zonse chifukwa cha mphamvu zotentha ndipo amasuntha mwachisawawa mumsewu wosweka chifukwa cha kugunda ndi tinthu tating'onoting'ono tomwe tikuyenda, mwachitsanzo, kusuntha kwa Brownian Popanda mphamvu yakunja, mtengo wapakati wamakono opangidwa. ndi kayendedwe ka Brownian kwa ma elekitironi ndi ofanana ndi ziro, koma gawo la AC lidzapangidwa.Chigawo cha AC ichi chimatchedwa phokoso la kutentha.Phokoso la kutentha kumakhala ndi ma frequency osiyanasiyana, kuchokera pa 0 Hz mpaka 102 Hz, ndipo onse amayalidwa mofanana.
Iyi ndi nkhani ya "phokoso mu njira" yomwe idabweretsa kwa inu ndi Shenzhen HDV phoelectron Technology Co., Ltd. ndikuyembekeza kuti nkhaniyi ingakuthandizeni kukulitsa chidziwitso chanu.Kupatula nkhaniyi ngati mukuyang'ana kampani yabwino yopanga zida zoyankhulirana zama fiber zomwe mungaganizirezambiri zaife.
Malingaliro a kampani Shenzhen HDV phoelectron Technology Co., Ltd., Ltd. makamaka amapanga zinthu zoyankhulirana.Pakadali pano, zida zomwe zimapangidwa zimakwiriraZithunzi za ONU, Optical module mndandanda, Zithunzi za OLT,nditransceiver mndandanda.Titha kupereka ntchito makonda pazochitika zosiyanasiyana.Mwalandiridwafunsani.
