SQS Vláknová optika a.s. is producer of Vacuum Optic patchcords/jumpers suitable for High Vacuum or Ultra High Vacuum (UHV) environment. Process of assembling Vacuum patchcords needs UHV compatible process of gluing as well as UHV connectors and bare fiber protected by loose tube. For vacuum the most common connectors are FC connectors. The SMA 905 connector are alos available. All mentioned patchords can be mated in Vacuum FC adapters which are also part of our offer as well as Vacuum compatible fiber optic feedthroughs with pigtail or adapter interface.

Applications

  • Excellent optical parameters
  • UHV compatible patchcords/adapters
  • Precise optical length on request
  • UHV FO feedthrough on request
  • In SM, MM and PM version
