Fiber Optics vs. T1 Line Security

both are dedicated lines.

both are high capacity.

the t1 copper may have an rf signal than could be received or interfere with transmition.

both have the same security risks of being connections to systems outside your control.
you can get a t1 fiber, it costs more than the copper, but has no rf noise possibility.

it's no real difference security wise, but performance wise and scalability, the fiber is a better option.

Thats a good argument you make

Have you received an answer on your T1? In the beginning a T1 Line may be difficult. Let me know
