Moreover, adaptive equalization, ch- nel coding or maximum likelihood detection are still considered something “exotic” in the optical world. Lemaire, Block turbo code performances for long-haul DWDM optical transmission systems. Instead, modern codes are evaluated in terms of their bit error rates. For the fiber-optic device, see optical interleaver.

If the FEC overhead values are different, the receiver defaults to the highest overhead selected by the two nodes (step 52). Picart, S. D t = 1 error corrected Increases Burst Error Correction Capability 13. Mizuochi, Automatically tracked dispersion compensation with penalty–free tunable dispersion equalizer for 40 Gbit/s systems.

Sole-Pareta, S. Humblet, M. These values are obtained by scaling the power consumption of RS and LDPC FEC devices [38], [39] as well as FFT processors in [40] to 60 GHz sampling rate and 100 P.

Disadvantages of interleaving[edit] Use of interleaving techniques increases total delay. R. Sugihara, Demonstration of PMD mitigation in long–haul WDM transmission using automatic control of input state of polarization. Generally the specific BER is not required and the order of magnitude of BER is already enough for problem analysis.
