4. RECOMMENDED EDFA VALUES
The following recommended values are to be considered while using the maximum Fiber length of your
network. Booster values may need to be adjusted if a shorter Fiber length is used.
The following values are based on a 10G SFP+ s1dBm of light power for the 10G 140km and 10G
200km EDFA-MUX models, and a 100G QSFP sending -6.5dB of light power for the 100G EDFA-MUX models.
The Fiber attenuation values in this table are assuming a Fiber without splices, and a loss of 0.2dB/km.
