Wavelength routing of 40 Gbit/s packets with 2.5 Gbit/s header erasure/rewriting using all-fibre wavelength converter

40 Gbit/s packet wavelength routing and 2.5 Gbit/s header replacement is demonstrated using an ultra-high-speed wavelength converter. Burst-mode bit error rate measurements are performed on both the header and payload before and after wavelength routing, with <4 dB penalty in the payload and <2.5 dB penalty in the header.
