Question: Does the MA5620/MA5626 support GE upstream transmission?
Answer: Check the type of the upstream port on the device. If the upstream port can be connected to an optical fiber only after a pluggable optical module is inserted into the port, you can insert a GE optical module to implement GE upstream transmission. If the upstream port can be directly connected to an optical fiber without an optical module, it does not support GE upstream transmission.
