Menara tunable XFPs (http://www.menaranet.com/products_tunable_xfp.htm)
work quite well in Juniper MX routers, and they have FEC integrated on
the XFP. We did a test this summer on a 500 km (approx) DWDM system with
optical amplifiers only, no electronic regeneration, and are very happy
with the results. Wavelength configured by CLI. Rerouting based on BER
is *not* integrated with JunOS, though.
