Description
The ER12-6 Er-doped single-clad fiber features a high absorption and high quantum efficiency that make this product the ideal solution for the design of optical telecom amplifiers. It is also an excellent alternative to the ER8-6 fiber, as its higher absorption would benefit the efficiency required by some telecom applications.
Features & Benefits
- Low background losses
- High doping concentration – provides highly efficient energy transfer
- Low splice loss
Applications
- Erbium-doped fiber amplifiers (EDFA)
- Telecom
