Optical Amplifiers

GAO’s optical amplifiers are devices used in optical communication systems to boost the power and quality of optical signals. They operate by amplifying the optical signal without the need for converting it into an electrical signal and then back into an optical signal.

GAO’s optical amplifiers are composed of a gain medium, pump source, pump coupling system, isolators, filters, housing, and connectors.

The other common names of optical amplifiers are optical boosters, optical repeaters, light amplifiers, fiber amplifiers, signal regenerators, amplifying glasses, laser amplifiers, optical gain mediums, optical Doppler amplifiers, and erbium-doped fiber amplifiers (EDFAs).

GAO Tek’s optical amplifiers have the following functions:

  • Signal Amplification: Our optical amplifiers increase the power level of optical signals without the need for electrical conversion. They directly amplify the optical signal, which allows for efficient and high-quality transmission over long distances.
  • Erbium-Doped Fiber Amplifiers (EDFAs): Erbium-doped fiber amplifiers (EDFA) use erbium-doped optical fibers as the amplification medium. When pumped with an external light source, such as a laser, the erbium ions in the fiber become excited and can amplify incoming optical signals.
  • Amplification Bandwidth: Our optical amplifiers have a specific amplification bandwidth, typically in the range of hundreds of nanometers, which corresponds to the wavelengths of light that they can amplify effectively.
  • Inline Amplification: GAO optical amplifiers can be placed at specific intervals along the fiber optic transmission line to compensate for signal loss due to fiber attenuation. This allows for the transmission of signals over longer distances without significant degradation.
  • Wavelength Transparency: GAO’s optical amplifiers are wavelength-transparent, which means they can amplify signals at different wavelengths simultaneously. This makes them suitable for wavelength division multiplexing (WDM) systems.
  • Regenerative Amplification: Our optical amplifiers can also perform regenerative amplification. Regeneration involves reshaping and cleaning up degraded optical signals by converting them into electrical signals, performing signal processing or regeneration, and converting them back into optical signals using optical amplifiers.

GAO Tek’s optical amplifiers are rugged, versatile, and precision measurement instruments. They comply with applicable industry standards such as ITU-T G.694.1, ITU-T G.694.2, ITU-T G.692, ITU-T G.709, Telcordia GR-253, and MSA (Multi-Source Agreement) Standards.

Our optical amplifiers help our customers comply with relevant U.S. government regulations such as:

  • Occupational Safety and Health Administration (OSHA)
  • National Institute of Standards and Technology (NIST)
  • Department of Defense (DoD)

Our optical amplifiers help our clients in complying with relevant Canadian government regulations such as:

  • Innovation, Science and Economic Development Canada (ISED)
  • Canadian Radio-television and Telecommunications Commission (CRTC)
  • Measurement Canada Requirements
  • Canadian Standards Association (CSA)

Our optical amplifiers have the following applications:

  • Long-Haul Optical Communication: In long-haul optical communication systems, our optical amplifiers are for compensating for signal losses that occur as the optical signals travel over long distances.
  • Dense Wavelength Division Multiplexing (DWDM) Systems: GAO’s optical amplifiers are used in DWDM systems, which allow for the simultaneous transmission of multiple optical signals at different wavelengths over a single fiber.
  • Fiber-to-the-Home (FTTH) Networks: Our optical amplifiers are used in FTTH networks, which bring high-speed fiber optic connectivity to residential and business premises. The amplifiers help compensate for the signal losses that occur as the optical signals travel from the central office to the end users, ensuring reliable and efficient signal delivery.
  • Submarine Fiber Optic Systems: In submarine communications systems, where fiber optic cables are laid across vast distances under the ocean, our optical amplifiers are used to overcome the signal attenuation caused by the long cable lengths.
  • Optical Networks with Multiple Splitters: GAO optical amplifiers are employed in optical networks that feature multiple optical splitters or branching points. These networks require amplification to compensate for the signal splitting and to maintain adequate signal strength across the network, enabling efficient and reliable communication.
