A quotation from Carlyle

   The last quality, perseverance, I particularly respect: it is the very hinge of all virtues. — On looking over the world, the cause of nine parts in ten of the lamentable failures which occur in men’s undertakings & darken and degrade so much of their history, lies not in the want of talents or the will to use them, but in the vacillating and desultory mode of using them — in flying from object to object, in starting away at each little disgust, and thus applying the force which might conquer any one difficulty to a series of difficulties so large that no human force can conquer them.
   The smallest brook on earth, by continual running, has hollowed out for itself a considerable valley to flow in: the wildest tempest, by its occasional raging, over-turns a few cottages, uproots a few trees, and leaves after a short space no mark behind it. Commend me therefore to the Dutch virtue of perseverance! Without it all the rest are little better than fairy gold, which glitters in your purse, but when taken to the market proves to be — slate or cinders.

Thomas Carlyle (1795-1881) Scottish essayist and historian
Letter (1822-03-15) to John Carlyle

Fibre-Optic Curiosity Poll: people who deploy single-mode point-to-point fibre links (any distance beyond inside a datacenter), do you use two-strand optics, or single-strand with two colours? Please #boost!

I very much lean on Bi-Di optics since I figure there's half the amount of OSP cable to go wrong, and swapping failed optics is MUCH easier than splicing a bad strand in an inaccessible flooded underground vault that's on fire.

Let me know in the comments what you do, and why.

[Note top-of-rack/intra-rack and in-datacenter is NOT what I'm asking about that. That's the realm of MMF and DACs.]

Additionally I'm wondering about NNIs and medium-haul 100G+ links, since bidi there is LESS common, but is beginning to happen. LR4 -> LR2 <- LR1???
