GAOTek Optical Muxponder

GAOTek optical muxponder is mainly used in metro area nodes, and it solves the following shortage of fiber resources below the metro area network, completes a unified load and flat networking for multiple services in industries.

GAO Tek’s muxponders have the following functions,

  • Multiplexing: The primary function of our muxponders is to combine multiple signals from different sources into a single composite signal. It takes input signals, which can be in different formats and protocols such as Ethernet, SONET/SDH, or Fiber Channel, and multiplexes them together. This enables efficient utilization of the available bandwidth and capacity of the fiber optic link.
  • Trans-ponding: Our muxponders perform the transponder function, which involves converting the multiplexed electrical signals into an optical format suitable for transmission over a fiber optic link. It performs modulation, encoding, and other necessary operations to prepare the data for optical transmission.
  • Wavelength Assignment: In dense wavelength division multiplexing (DWDM) systems, where multiple wavelengths of light are used to transmit data over the same fiber, our muxponders assign the multiplexed signal to a specific wavelength. It ensures that each wavelength carries the appropriate combination of signals.
  • Protocol Conversion: GAO’s muxponders can also perform protocol conversion, allowing signals of different protocols and speeds to be combined and transmitted over a common wavelength. For example, it can convert Ethernet signals to SONET/SDH or Fiber Channel signals, and vice versa.
  • Optical Power Management: GAO’s muxponders incorporate optical power management features to monitor and control the optical power levels of the transmitted signals. This ensures that the optical signals are within the acceptable power range for proper transmission and avoids signal degradation or damage to the network components.

GAO Tek’s muxponders are rugged, versatile, and precision measurement instruments. they comply with applicable industry standards such as optical transport network (OTN) standards, ethernet standards, synchronous optical networking (SONET) and synchronous digital hierarchy (SDH) standards, fiber channel standards, dense wavelength division multiplexing (DWDM) standards, management, and control standards.
