By Michelle Collier, RCDD. Fiber optic cable provides a low loss medium for high-speed communications. While. the continuous fiber cable itself is low loss, terminations at each access point provide a. potential Achilles heel.

The blue crab's scientific name, Callinectes sapidus, is from Latin and Greek: calli, beautiful; nectes, swimmer; and sapidus, savory-beautiful, savory swimmer. Like insects, blue crabs have stalked compound eyes and can see in almost every direction at once.
The Maryland Department of Natural Resources and Virginia Institute of Marine Science have partnered since 1990 on annual winter surveys of the blue crab in the Chesapeake Bay. In all, they estimated this year's population at 455 million, down 18 percent from 2016.
