We experimentally demonstrate the compatibility of wavelength multiplexed active polarization stabilization for quantum communication in an optical fiber carrying telecom traffic. One of the feedback control channels contains a 9.953 Gb/s datastream generated from a BER meter. We verify the ability to transmit single‐photons in the two opposite directions of a 23‐km optical fiber spool, while maintaining their state of polarization stable and a classical BER in the feedback channel error‐free, during 6 h of continuous operation. © 2011 Wiley Periodicals, Inc.
