| LIEKKI Er30-4/125 |
Erbium doped fiber
|
| Product description |
|
LIEKKI Er30-4/125 is a highly doped erbium fiber designed for C- and
L-band amplifiers and ASE sources. This fiber is available in two
versions: low cut-off and high cut-off. 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 20m.
