  1. No wonder optical networks are in such a poor state, especially if people like FOT are managing them. The language and grammar on this site is so bad you probably can’t read the instruction manuals for optical network equipment. I guess you are trying to drive customers away. 100% success with me, I will never visit your site again or recommend you to anyone.
