Check it out again. Crane super computer builds their computer system. The last time they upgraded the released the system specs of their old computer and it was the most powerful computer even seen. There computers were linked together by coax cables witch was unheard of at the time. Some computer experts believe the old reason for them to have upgraded is because they have a new system linked fir fiber optics. Most private computer manufactures are still trying to make a fiber optic computer that is viable.
The backdoors are placed there intentionally
If you did read my full post you would of seen the comment that the telecommunications switches have built in ports for just that type of connections.

NSA has inserted code that permits them to extract the crypto key and decrypt data using an ordinary level of computing power. The crypto is not being broken by means of massive, brute force techniques.
Just because a computer employs fiber optic connections does not mean it is a "fiber optic" computer. Fiber optics are often used for classified interconnections because they do not radiate signals. I've installed fiber optic connections between Tempest workstations and remote classified computers at SHAPE in Belgium.
It is no surprise that agencies can extract a DS0 stream from a DACS switch in the central office to tap a conversation undetected. That is 1980 technology.
