Recently, there are several Tap devices in the market and they are servicing instead of copy ports in traffic monitoring. Many famous company such as NetOptics and ..... have variety of products suit for single mode, Multimode and .... fibers. It is not a new topic to discuss.
...seems to be the only answer at the moment to secure any high speed data stream.
Let's all hope that Quantum key distribution like Alice and Bob will do, what they promise!

For many reasons Quantum Cryptography is not the solution to the problem in question (when properly implemented QC is realy only applicable to crypto key distrubution etc due to it's many inherant limitations).
One problem with practical Quantum Crytpo systems is that to get it to work over any sizable distance at a reasonable bit rate you end up sending more than a single photon per bit...
So this tap may well work against Quantum Crypto if it is put close to the emitter (there is also one hell of a lot of other things you would have to do as well but hey it's enough to hang your hat on and get down to work).
Also very slowly bending the QC cable in a tight cure to increase the "line loss" is a way by which you can get somebody to change their threshold on quantum crypto systems.
Although quantum crypto is a nice idea real world implementations have to take into account a whole host of other issues (not least the same laws of physics by which it works,) that for practical purposes make QC (effectivly) a theoretical system only.

Tom,
Nice post, simple but full of information. I work for a company that secures the access points that you talked about. It baffles me how many companies are overlooking this security hole. Almost as if they think it won't happen to them.

On the copper side, there is at least one product that has security built-in. Siemon introduced a shielded copper cabling system named "TERA" back in 1999 that has more recently been validated for TEMPEST high-security government applications.
While it does not use the typical RJ-45 form factor, the TERA interface and cable are standards approved for ISO/IEC category 7/class FA specifications. The standards at this level call for 1,000 MHz frequency bandwidth - ideal for 10GBASE-T and broadband CATV applications.

This is possible for a single fiber. But what if data to be tapped is transmitted in the fiber which is in the middle of an OFC bundle. Then this method fails, isn't?
