Submarine Cable Networks

>Throughout the life cycle of a submarine cable network, it is critical to use the best test and monitoring tools available to maximize transmission capacity and network availability.

• Fiber Inspection

  Fiber end face inspection remains the essential test tool to ensure connector cleanliness and detect dirt particles or other defects whose impact can be magnified over potentially thousands of km.

  • FiberChek Probe Microscope
• Optical Time Domain Reflectometry (OTDR)

  OTDR test tools validate the physical integrity and losses of the fiber links, as-well-as accurately mapping out the distances to any faults. The 8100D OTDR, the industries only true 50dB dynamic range OTDR, allows certification and troubleshooting of unprecedented sub-sea distances, while the FiberComplete® automated bi-directional Insertion Loss (IL), Optical Return Loss (ORL) and OTDR solution offers the tool of choice to qualify unrepeated links and first wet segment.

  • OTDR Modules – 8100-Series for T-BERD/MTS-6000A, -8000 Platforms
  • FiberComplete Integrated Loss, ORL and OTDR Modules – 8100-Series for T-BERD/6000A, -8000 Platforms
• Fiber Characterization

  Optical network characterization test tools with Chromatic Dispersion (CD) and Polarization Mode Dispersion (PMD), as well as Attenuation Profile, provides the base line information to guarantee the physical performance of the fibers in the cables.

  • Optical Dispersion Measurement Modules for T-BERD/MTS-6000A, -8000 Platforms
• Optical Spectrum Analysis

  Service activation with modern DWDM transmission formats like Polarization-Multiplexed, requires state of the art spectrum analyzers with In-Service an In-Band OSNR testing capability combined with high resolution.

  • High performance OSA-500 Series for T-BERD/MTS-8000 Platforms
  • In-service Pol-Mux OSCA-710 for T-BERD/MTS-8000 Platforms
• Network Service Test

  The large variety of transmission speeds and formats carried along submarine cables demand flexible multiservice test solutions for SONET/SDH or Ethernet (up to 100Gb/s) and OTN (OTU3) qualification and validation. Portable or rack-mounted solutions will provide automation and remote testing capabilities.

  • T-BERD/MTS-5800 100G
  • MAP-2100
• Monitoring & Maintenance

  Monitoring and maintenance are the keys to ensuring the on-going health of both the dry and “non-amplified” wet plants as well as offering a solution to watch the first critical segment of any amplified link.To protect the fiber physical link an effective optical network monitoring system, such as ONMSi or SmartOTU, provides real time information about faults, degradation, and any security related issues.

  Pushing and maximizing the capacity of a submarine network also requires considering new parameters such as fluctuations in strain or temperature of the fibers in the links. Fiber optic sensing tools play a critical role in such a qualification.
