Application of Optical Light Sources

  • While some fall under the multipurpose category, for example, automated features, optimized for specific tasks such as detecting faults, breaks and microbends in the fiber.
  • Light source working on FTTH/PON area.
  • A straightforward instruments let you accurately measure signal attenuation during fiber-optic cable deployment in FTTx/PON access networks and LAN/WAN links, certify premises networks, and perform any other task related to general outside plant installations.
