This effect was first seen in networks using CSMA/CD on Ethernet. Because of this effect, the most data-intense connection dominates the multiple-access wireless channel. [12] This happens in Ethernet links because of the way nodes "back off" from the link and attempt to re-access it.
The respective contributions of the two cable systems to this blackout is unclear. Network outage graphs suggest that the two breaks occurred at 04:30 and 08:00 UTC. [23] The cause of the damage was not declared by either cable operator, but news sources speculated the damage was caused by a ship's anchor near Alexandria.
Networking cable is a piece of networking hardware used to connect one network device to other network devices or to connect two or more computers to share devices such as printers or scanners. Different types of network cables, such as coaxial cable , optical fiber cable , and twisted pair cables, are used depending on the network's topology ...
An example is the cable between Singapore and Indonesia, which was partly robbed in 2013: 31,7 km and 418 tons of cables were removed. [33] Another scenario is a criminal group threatening to harm cables if no ransom is received. Last, cables could be damaged to cover an unrelated criminal attack, as it would diminish surveillance capacities. [34]

OC-12 is a network line with transmission speeds of up to 622.08 Mbit/s (payload: 601.344 Mbit/s; overhead: 20.736 Mbit/s). OC-12 lines were commonly used by ISPs as wide area network (WAN) connections, or connecting xDSL customers to a larger internal network [ 3 ]
Fiber optic cables connect the headend or hub to the optical nodes in a point-to-point or star topology, [25] or in some cases, in a protected ring topology. Each node can be connected via its own dedicated fiber, [ 26 ] so fiber optic cables laid outdoors in the outside plant can have several [ 27 ] dozen to several hundred or even thousands ...
Large voltages were used to attempt to overcome the electrical resistance of their tremendous length but the cables' distributed capacitance and inductance combined to distort the telegraph pulses in the line, reducing the cable's bandwidth, severely limiting the data rate for telegraph operation to 10–12 words per minute.
