The present invention discloses a method for locating the reference frames of the reference lane on the transmitting data bus. The present invention addresses this object by disclosing a method whereby the relationship between the size of the reference frame transmitted over the reference lane and the width of the data bus is such that the reference frame is bit-shifted automatically until it is aligned with the data bus.

A filter and a method of filtering a high frequency electrical signal using photonic components is disclosed. The filter has a serially fiber-coupled laser source, a modulator, a filter, and a photodetector. The electrical signal is applied to the modulator. The modulated light propagates through the filter which is constructed to pass not only a modulated sideband, but also at least a fraction of light at the carrier frequency of the laser. The photodetector detects a signal at the beat frequency between the carrier and sideband signals, after both signals have propagated through the filter. As a result, a separate optical branch for light at the carrier frequency is not required, which considerably simplifies the filter construction and makes it more stable and reliable.
