An optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire) is a type of cable that is used in overhead power lines. Such cable combines the functions of grounding and communications .
Wireless backhaul is easy to deploy, cost efficient and can provide high capacity connectivity, e.g., multiple gigabits per second, and even tens of Gbps. Wireline fiber backhaul, on the other hand, can provide practically endless capacity, but requires investment in deploying fiber as well as in optical equipment.
EPON is a "short haul" network using Ethernet packets, fiber optic cables, and single protocol layer. [1] EPON also uses standard 802.3 Ethernet frames with symmetric 1 gigabit per second upstream and downstream rates. EPON is applicable for data-centric networks, as well as full-service voice, data and video networks.

Loss = dB loss per connector × number of connectors + dB loss per splice × number of splices + dB loss per kilometer × kilometers of fiber, where the dB loss per kilometer is a function of the type of fiber and can be found in the manufacturer's specifications. For example, a typical 1550 nm single-mode fiber has a loss of 0.3 dB per kilometer.
The CFO said the journey cost $293,000 for two travelers in the ship's owner's suite and included $13,000 in shipboard credits, as well as a $25,000 Costco Shop card.
