Kapangidwe ka zipangizo kuwala kulankhulana

Kapangidwe kazipangizo zoyankhulirana za kuwala

Njira yolankhulirana yokhala ndi mafunde a kuwala monga chizindikiro ndi Chingwe cha Optical monga njira yotumizira imatchedwa Optical fiber communications system. Ubwino wa kuyankhulana kwa fiber optical poyerekeza ndi kulankhulana kwachikhalidwe ndi kuyankhulana opanda zingwe ndi: kulankhulana kwakukulu, kutayika kochepa, mphamvu zotsutsana ndi magetsi, chinsinsi champhamvu, ndi zopangira za optical fiber transmission sing'anga ndi silicon dioxide yokhala ndi zosungira zambiri. Kuphatikiza apo, CHIKWANGWANI chowoneka bwino chimakhala ndi zabwino zazing'ono, zopepuka komanso zotsika mtengo poyerekeza ndi chingwe.
Chithunzi chotsatirachi chikuwonetsa zigawo za gawo losavuta la Photonic Integrated:laser, kugwiritsanso ntchito kuwala ndi demultiplexing chipangizo,Photodetectorndimodulita.

Kapangidwe kake ka mawonekedwe a optical fiber bidirectional communication system akuphatikiza: chopatsira magetsi, chotumizira magetsi, ma transmitter, fiber, cholandila ndi cholandila magetsi.
Chizindikiro chamagetsi chothamanga kwambiri chimasungidwa ndi cholumikizira chamagetsi kupita ku transmitter yamagetsi, kusinthidwa kukhala ma siginecha owoneka ndi zida za electro-optical monga chipangizo cha Laser (LD), kenako ndikuphatikizidwa ndi fiber transmission.
Pambuyo pa kufalikira kwa mtunda wautali kwa chizindikiro cha kuwala kudzera muzitsulo zamtundu umodzi, erbium-doped fiber amplifier ingagwiritsidwe ntchito kukulitsa chizindikiro cha kuwala ndikupitiriza kufalitsa. Pambuyo pa mapeto olandira optical, chizindikiro cha kuwala chimasinthidwa kukhala chizindikiro cha magetsi ndi PD ndi zipangizo zina, ndipo chizindikirocho chimalandiridwa ndi wolandira magetsi kupyolera muzitsulo zotsatila zamagetsi. Njira yotumizira ndi kulandira zizindikiro kumbali ina ndi yofanana.
Kuti akwaniritse kuyimitsidwa kwa zida mu ulalo, transmitter optical ndi optical receiver m'malo omwewo akuphatikizidwa pang'onopang'ono mu Transceiver optical.
Liwiro lalitaliOptical transceiver moduleimapangidwa ndi Receiver Optical Subassembly (ROSA; Transmitter Optical Subassembly (TOSA) yoimiridwa ndi zida zogwira ntchito, zida zogwira ntchito, zozungulira zogwirira ntchito ndi zigawo za mawonekedwe azithunzi zimayikidwa. tchipisi cha kuwala.

Poyang'anizana ndi zovuta zakuthupi ndi zovuta zaukadaulo zomwe anakumana nazo pakupanga ukadaulo wa ma microelectronics, anthu adayamba kugwiritsa ntchito mafotoni ngati zonyamulira zidziwitso kuti akwaniritse bandwidth yayikulu, kuthamanga kwambiri, kugwiritsa ntchito mphamvu pang'ono, ndikuchepetsa kuchedwa kwa photonic inteated circuit (PIC). Cholinga chofunikira cha photonic Integrated loop ndikuzindikira kusakanikirana kwa ntchito za kuwala kwa kuwala, kugwirizanitsa, kusinthasintha, kusefa, kufalitsa, kuzindikira ndi zina zotero. Mphamvu yoyamba yoyendetsa ma photonic integrated circuits imachokera ku kuyankhulana kwa deta, ndiyeno yapangidwa kwambiri mu microwave photonics, quantum information processing, nonlinear optics, masensa, lidar ndi zina.
