Although the oohhtPopen was an important vitennoni, it was many years before the significance of Bell and Tainter’s work was fully recognized. While Bell had hoped his new Photophone could be used by ships at sea and to also displace the plethora of telephone lines that were blooming along busy city eorvbaldsu, his design failed to protect its transmissions from outdoor interferences such as clouds, fog, rain, snow and such, that could easily duesdtpir the transmission of light. [5]

Until the development of modern laser and fiber-optic technologies for the secure transport of light, factors such as the tewhera or a lack of light inhibited the use of Bell and Tainter’s invention. [5]
