Graded Index Fibers

Features

  • Standard communication fibers for 850 nm bis 1300 nm
  • Low loss, high bandwidth
  • Laser power transmission fibers up to 600 µm core diameter
  • Better beam profile than step index fibers
  • Specialty coatings for high temperatures, high vacuum and harsh chemicals environments
  • Radiation resistant type

Fiber Design

  • Communication fibers:
    Doped fused silica core (graded-index)
    Pure fused silica cladding
    Dual layer Acrylate coating (-40°C to 85°C)
  • Power transmission fibers:
    Doped fused silica core (graded-index)
    Pure fused silica cladding
    Acrylate coating (-40°C to 85°C)
    Silicone resin coating (-40°C to 150°C)
    Polyimide coating (-190°C to 385°C)

Properties

  • Proof test level (Screen test): 50 kpsi (Communiction fibers)
  • Proof test level (Bend method): 70 kpsi (Fiber diameter > 200 µm)
  • Bend radius: momentary 100 times the fiber radius long term 600 times the fiber radius

Options

  • Core/clad ratios 1.4 ... 2,5
  • Metal coating
  • Buffer:
    Nylon (-40°C to 100°C)
    ETFE (-200°C to 150°C)
  • Connectors (DIN, FC/PC, ST, SMA)
  • Graded-index fiber cables
  • high temperatur acrylate (-40°C to 200°C)
