Optical Add / Drop Multiplexer Cable

Optical Add / Drop Multiplexer Cable

Extending the capabilities of Fiber Driver WDM systems, the Fiber Driver OADM (Optical Add/Drop Multiplexer) cables create a network topology in which a wavelength can be added or dropped on demand. The cable itself covers the functionality of one single fiber, thus two of these cables are required in order to implement a dual fiber OADM, one providing the add function, while the second implementing the drop one. The technology enables flexible and intelligent planning and provisioning of optical services while at the same time simplifying the deployment and maintenance of the optical network." to: "CWDM and DWDM Optical Add/Drop Multiplexers (OADM) provide data access for intermediate network devices along a shared optical media network path. Regardless of the network topology, OADM access points allow design flexibility to communicate to locations along the fiber path.

Applications

    Theory of Operations

  • An Add/Drop module located on a WDM link allows access to individual grid wavelengths without disrupting the other signals. One or more wavelengths may be dropped from the multiplexed signal to receiving devices, and these wavelengths are returned from the same location and multiplexed back into the common trunk. An Epress port passes the wavelengths that were not dropped downstream for access at another location.

  • The signal downstream from an Add/Drop module no longer includes the accessed wavelengths, so there is unused bandwidth on these fibers. An identical Add/Drop module may be installed “back-to-back” with the first to use these wavelengths, or a two-sided module may be used that combines this configuration into a single module for high-density and high-usage applications.
  • Passive optical technology is not directional, so light signals may pass in either direction. While an Add module may perform the Drop function simply by sending the signal in the opposite direction, each module is designed to minimize insertion loss to the transmission. Multiple-port Add/Drop modules are therefore designed with matched pairs to balance the insertion loss across the virtual link ports. Balanced insertion losses by wavelength are important when budgeting optical transmission power for a WDM network.

  • A bi-directional link may be created with either a pair of one-way\"uni-directional\" fibers or a single two-way “bi-directional” fiber, each channel using a different wavelength for data in the two directions. Since a data light source may appear at either end of a link, a WDM link may carry a set of wavelengths in each direction to establish multiple bi-directional links over a single fiber."
