Gulu la ochita kafukufuku ochokera ku yunivesite ya Tsinghua (China) lapanga njira yomvera zokambirana m'chipinda chokhala ndi chingwe cha kuwala, monga chomwe chimagwiritsidwa ntchito kugwirizanitsa ndi intaneti. Kugwedezeka kwa mawu kumapangitsa kusiyana kwa kuthamanga kwa mpweya, komwe kumayambitsa ma microvibrations mu chingwe cha kuwala, chosinthidwa ndi mafunde a kuwala omwe amafalitsidwa kudzera pa chingwe. Zopotoka zomwe zimachitika zimatha kusanthula patali kwambiri pogwiritsa ntchito laser interferometer ya Mach-Zehnder.
Pa kuyesera, zinali zotheka kuzindikira bwino zolankhulidwa pamene panali atatu mita lotseguka chidutswa cha kuwala chingwe (FTTH) mu chipinda kutsogolo kwa modemu. Miyezoyo idapangidwa pamtunda wa 1.1 km kuchokera kumapeto kwa chingwe chomwe chili mchipinda chochezera. Mtundu womvera komanso kuthekera kosefera kusokoneza kumagwirizana ndi kutalika kwa chingwe mu chipinda, i.e. Pamene kutalika kwa chingwe m'chipindacho kumachepa, mtunda wautali umene kumvetsera kumatheka kumachepanso.
Zimawonetsedwa kuti kuzindikira ndi kubwezeretsedwa kwa chizindikiro cha audio mu optical communication networks akhoza kukhazikitsidwa mobisa, osadziwika ndi chinthu chomvetsera komanso popanda kusokoneza ntchito zoyankhulirana zomwe zimagwiritsidwa ntchito. Kuti alowe mu njira yolankhulirana mosadziwika bwino, ofufuzawo adagwiritsa ntchito njira yolumikizira yavelength (WDM, Wavelength Division Multiplexer). Kuchepetsa kwina kwa phokoso lakumbuyo kumatheka mwa kugwirizanitsa mikono ya interferometer.
Njira zopewera kutchera khutu kumaphatikizapo kuchepetsa utali wa chingwe chowonekera mchipindacho ndikuyika chingwecho munjira zolimba. Kuti muchepetse kumvetsera bwino, mutha kugwiritsanso ntchito zolumikizira zamagetsi za APC (Angled Physical Connect) m'malo mwa zolumikizira zam'mphepete (PC) polumikiza. Ndibwino kuti opanga zingwe zowunikira agwiritse ntchito zida zokhala ndi zotanuka modulus, monga chitsulo ndi galasi, monga zokutira za fiber.
