N'afọ 1976-1986, ebumnuche nyocha bụ imeziwanye ọnụego nnyefe na ịbawanye anya nnyefe, na ịkwalite nkwalite mmepe nke ngwa nke sistemu fiber optical. N'oge a, eriri sitere na multimode gaa n'otu ọnọdụ, yana arụ ọrụ wavelength nwekwara mepụtara site 850nm mkpụmkpụ wavelength ka 1310nm / 1550nm ogologo wavelength, ọbọ a otu mode eriri nkwurịta okwu usoro na a nnyefe ọnụego nke 140 ~ 565 Mb / s. N'ihe gbasara ihe nkwuputa, ebe nnyefe nwere ike iru 100km.
Ọgbọ nke atọ ngwa anya eriri nkwurịta okwu usoro

Fiber na-eji usoro ngbanwe nke mpụga (electro-optical device) nwere ọnụego nnyefe ruru 10 Gb / s yana ebe nnyefe ruru 150 km na-enweghị ihe nrịbama relay.
Ọgbọ nke anọ ngwa anya eriri nkwurịta okwu usoro
1996-2009 bụ oge nke synchronous dijitalụ usoro ngwa anya eriri nnyefe netwọk. Usoro nkwurịta okwu fiber optic na-ewebata ngwa ngwa anya iji belata ọchịchọ nke ndị na-emegharị ihe.
