Reminds me of a data center that said they had a backup connection and I pointed out that only one fiber was coming into the data center. They said, "Oh its on a different lambda[1]" :-) [1] Wave division multiplexing sends multiple signals over the same fiber by using different wavelengths for different channels. Each wavelength is sometimes referred to as a lambda.
