Does the GE optical LPU of the S7700&S9700 support 100M optical module

The S7700&S9700's GE optical LPU supports both 100M optical modules and 1000M optical modules.
When a 100M optical module is used, you must run the speed 100 command on the interface to set the interface rate to 100 Mbit/s.
When using a GE optical module, an interface works at 1000 Mbit/s by default. If auto-negotiation is enabled on the interface, the interface speed cannot be set to 100 Mbit/s. If auto-negotiation is disabled, you can run the speed 100 command to set the interface speed to 100 Mbit/s.
The 100M optical interface can only use the 100M optical module, and the default interface rate is 100M.
When two optical interfaces are interconnected, they must use the same type of optical module.
