Also check Whether the Fiber Type is Correct.

Most of the time we do not ensure if the port it is completely turned on, also we do not check the "Port Mode". Recommend to check first those kind of configurations if someone wants to configure SFP module.

Thanks for sharing, this may seem simple but sometimes we forget to check such basic things.
