文摘
- •
TDFA covers about 30 THz (1700–2100 nm) of amplification bandwidth.
- •
Add or drop channels in WDM networks causes the dynamic gain variation of TDFA.
- •
TDFA gain variation leads problematic transients and bit errors at the receiver.
- •
Optical gain clamping is a simple and robust technique to control the power transient.
