Overview

Ideal for C and L Band amplifiers

The amplification of optical transmission signals is enabled through our high efficiency Erbium doped fibers. Our wide range of Erbium doped optical fibers allows for tailored optical amplifiers (EDFAs) performance based on your requirements.
iXblue’s Erbium Doped Fibers (EDF) products have been optimized to fulfill the exigency of high efficiency and low noise EDFAs in the C & L bands.

For hundreds watt operation, iXblue offers double clad Erbium fibers with 30 to 100 µm core diameter.

Custom versions, from single clad up to triple clad or even multicore Erbium doped fiber are also available.

    ICSO – SEPTEMBER 2022

    A radiation tolerant Erbium fiber based optical frequency comb has been developed and environmentally tested. The system remained operable after an accumulated dose of 1 kGy. The underlying femtosecond fiber oscillator and Erbium fiber amplifiers have been manufactured from speciality doped fibers. The fiber optic system has been assembled and packaged using low outgassing components in a flight representative package before it was irradiated under active operation in two stages a 500 kGy. The accelerated ageing with dose rates of 10 mGy/s in water was tested using the calibrated Cobalt 60 source of the ESA-ESTEC facilities. The comb laser remained fully functional while the oscillator lost up to 30% of output power after the full exposure to the accumulated dose of 1 kGy. The fiber amplifiers lost 5-7% of output power.
