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 biggest cause of signal loss across fiber optic connectors is. contamination.
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.
How long do blue crabs live? That depends on how well they avoid predators. Typically, the life span for a female blue crab is 1-2 years and a male is 1-3 years; however, in some tagging studies, crabs aged 5 to 8 years old were caught.
