Erbium Doped Fiber, 4/125um, Core Absorption 40dB/m

LIEKKI TM Er30-4/125 fibers are highly doped erbium fibers designed for C- and L-band amplifiers, and ASE sources. These fibers are available as low cut-off fibers (Er30-4/125) and high cut-off fibers (Er30- 4/125HC).

The high cut-off version has demonstrated the highest power conversion efficiency available in L-band: better than 50% for a typical fiber length of 20 m.

Features
・Excellent batch consistency of erbium peak absorption and spectral shape
・Very short fiber lengths reduces non-linear effects like FWM, SRS and SBS
・Wide and flat spectrum
・Low polarization mode dispersion, typical value <25 fs/m
・Low splice loss, LIEKKI TM EasySplice software for splicing parameters
・Suitable for both 980 nm and 1480 nm pumping
・Telcordia GR–1312–CORE Generic Requirements qualified
・Dual layer UV-cured acrylate coating
