L-band Erbium-doped Fiber
Product Description
Product Detail
1. Introduction of L-band Erbium-doped Fiber
The L-band erbium-doped fiber is doped and optimized for L-band single-channel and multi-channel fiber amplifiers, ASE light sources, metropolitan area networks, CATV, and EDFA for DWDM. High doping can reduce the length of the erbium fiber, thereby reducing the nonlinear effect of the fiber. The fiber can be pumped at 980 nm or 1480 nm, and has low loss and good consistency with communication fiber connections.
2. Feature of L-band Erbium-doped Fiber
High consistency and stable performance;
It is suitable for different types of fiber optical amplifiers.
3. Application of L-band Erbium-doped Fiber
Single/Multi-Channel fiber optical amplifier;
ASE source.
