NOTE
1. The optical power calculation is based on the OMA value.
2. If the module needs to reach the nominal data, the board FEC function must be enabled.
3. When this type of optical module is used to interconnect with a WDM device, the 1+1
protection switching duration on the client side of the WDM device is longer than 50 ms.
