PM Erbium Doped Fiber
PM Erbium Doped Fiber combines Fibercore’s greatest areas of expertise: erbium doped fiber and Polarization Maintaining (PM) fiber. It unites the well-established core composition of IsoGain™ Erbium Doped Fiber (EDF), with options for PANDA stress rods or Bow-Tie stress applying parts. PANDA based fibers offer wider compatibility with PM splicers, better core concentricity for lower splice and connectorization losses whilst the Bow-Tie design offers higher birefringence for more robust maintenance of the polarization state across aggressive deployment states.
Advantages:
- Different absorption levels available
- PANDA and Bow-Tie designs for design optimization
- Different dispersion levels available
Typical Applications:
- PM EDFAs
- Coherent communications
- Quantum key distribution (QKD)
- Amplified spontaneous emission (ASE) light sources
- Fiber lasers
