SM-ESF-7/125, Er-Doped Select Cutoff SM, Optical Fiber
High performance erbium-doped fiber capabilities are demonstrated in a unique erbium fiber product, SM-ESF-7/125. This fiber features a high erbium concentration (peak absorption 55 dB/m) and high pump conversion efficiency achieved with proprietary technology that delivers industry leading tolerances on the key spectroscopic parameters. The polarization maintaining version of this fiber, PM-ESF-7/125, is also available for applications that require a polarized signal.
Features
- High Er dopant concentration-Enables short length devices
- High efficiency-Good conversion of pump to signal power
- RoHS compliant
Applications
- PM amplifiers
- Polarized lasers
- Ultra-short pulse laser
