Optical Add-Drop Multiplexers (OADM)

GAO’s optical add-drop multiplexers (OADM) are devices used in optical fiber communication systems to selectively add (insert) or drop (remove) individual wavelengths of light signals at specific points in the network. OADMs are used in dense wavelength division multiplexing (DWDM) systems, where multiple wavelengths of light are transmitted simultaneously over a single optical fiber. Our optical add-drop multiplexers enable the efficient and flexible management of optical signals in a DWDM system. By adding or dropping specific wavelengths at different network nodes, OADMs allow for the selective routing of signals, enabling network operators to add or remove traffic at specific locations without affecting the entire system.

GAO’s optical add-drop multiplexers are composed of multiplexers, demultiplexers, control and management interfaces optical switches, optical filters, and fiber optic connectors.

The other common names of OADM are optical add-drop multiplexing, optical channel drop/add, wavelength-selective add-drop, wavelength-selective multiplexer, DWDM add-drop, selective wavelength routing, optical demultiplexer, OXC with add-drop functionality, and WSS with add-drop capability.

GAO’s optical add-drop multiplexers have the following functions:

  • Multiplexing: GAO Tek’s optical add-drop multiplexers can combine multiple wavelengths of light signals onto a single optical fiber. This allows for efficient transmission of multiple signals over a single fiber, enabling high-capacity communication.
  • Demultiplexing: Our optical add-drop multiplexers can separate the combined wavelengths at the receiving end of the optical fiber. This process enables the individual wavelengths to be directed to their respective destinations or further processing.
  • Add/Drop functionality: One of the primary functions of our optical add-drop multiplexers is the ability to add or drop specific wavelengths of light signals at specific locations in the network. This feature allows network operators to selectively add or remove signals without affecting the entire network, providing flexibility in managing network traffic.
  • Selective wavelength routing: GAO’s optical add-drop multiplexers incorporate optical switches that enable the selective routing of wavelengths to different paths or destinations within the network. This allows for dynamic provisioning and reconfiguration of network connections as per the requirements.
  • Network restoration and protection: Our optical add-drop multiplexers are used in network resilience by providing alternate routing options in the event of a fiber cut or equipment failure. The optical switches can reroute traffic to bypass the affected segment, ensuring continuity of communication.

GAO Tek’s optical add-drop multiplexers 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.

GAO’s optical add-drop multiplexers have the following applications:

  • Dense Wavelength Division Multiplexing (DWDM) Networks: GAO's optical add-drop multiplexers are used in DWDM networks, which transmit multiple wavelengths of light over a single optical fiber. OADMs allow for the selective adding or dropping of specific wavelengths at different network nodes, facilitating efficient wavelength management and flexible network configurations.
  • Network Flexibility and Scalability: Our optical add-drop multiplexers provide network operators with the ability to add or remove specific wavelengths at desired locations without affecting the entire network. This flexibility and scalability allow for dynamic provisioning of bandwidth, making it easier to accommodate changing traffic demands and optimize network resources.
  • Traffic Aggregation and Distribution: GAO Tek’s optical add-drop multiplexers are used in aggregating traffic from multiple sources onto a single fiber and distributing it to different destinations. By selectively dropping and adding wavelengths, OADMs enable the routing of specific signals to their intended endpoints, facilitating efficient traffic distribution within the network.
  • Network Restoration and Protection: GAO’s optical add-drop multiplexers contribute to network resilience by providing the ability to reroute traffic in the event of a fiber cut or equipment failure. By using optical switches, OADMs can redirect signals to alternate paths, ensuring continuity of communication and minimizing the impact of network disruptions.
  • Optical Service Provisioning: Our optical add-drop multiplexers are utilized in optical service provisioning, where specific wavelengths are assigned to individual customers or services. OADMs allow for the efficient allocation of wavelengths to different users, ensuring dedicated and reliable optical connectivity for various applications.
