Swizzle FEC for 40G and 100G Optical Transmission

Abstract
The introduction of OTU3 at 40G and OTU4 at 100G has put a great deal of pressure on SNR budgets. A strong FEC is the most economical way of regaining some of the link budget.

The "Swizzle" Spiral Interleaved Turbo Forward Error Correction code is PMC-Sierra's third-generation FEC designed to meet the needs of 40G and 100G DWDM systems.

It offers 9.45dB of net coding gain with the standard 6.7% OTN overhead, 1.35dB better than the second-generation FECs captured in G.975.1.
