With a latency of 58.95ms, the cable currently provides the lowest latency fiber optic route between the NY4 data center in Secaucus, New Jersey and London. [3] The cable was considered operational on September 15, 2015. [4] EXA Express spans 4,600 km between its landing stations in Halifax, Nova Scotia; Brean, UK; and Cork, Ireland. The cable ...
A cable locator or cable avoidance tool (CAT) is an instrument used for detecting the presence and approximate location of buried services in advance of undertaking excavation works. It aims to avoid accidents while excavating. [ 1 ]
The conventionally used aid in cable fault testing and location is the cable test van. The van is installed with conventional cable measuring systems for quickly reaching the location of any cable fault. In 20 years that followed, over 2000 fault location vehicles were manufactured, more than half of which were intended for the former USSR.
A brittle grout surrounds the cable to translate earth movement into an abrupt cable deformation that shows up as a detectable peak in the reflectance trace. Until recently, the technique was relatively insensitive to small slope movements and could not be automated because it relied on human detection of changes in the reflectance trace over time.
Layer Four Traceroute (LFT) is a fast, multi-protocol traceroute engine, that also implements numerous other features including AS number lookups through regional Internet registries and other reliable sources, Loose Source Routing, firewall and load balancer detection, etc. LFT is best known for its use by network security practitioners to trace a route to a destination host through many ...
A time-domain reflectometer; an instrument used to locate the position of faults on lines from the time taken for a reflected wave to return from the discontinuity.. A signal travelling along an electrical transmission line will be partly, or wholly, reflected back in the opposite direction when the travelling signal encounters a discontinuity in the characteristic impedance of the line, or if ...
A Utility Search, also known as a C2 Utility Search or PAS128 (D) utility search, is the initial step in identifying utility asset owners and locating their buried and overhead assets and apparatus. A Utility Search is essential for development projects as it provides valuable insight into the presence and location of underground and overhead ...
HAW-1 (Hawaii No. 1) was the first submarine telephone cable laid between Hawaii and the mainland United States. HAW-1 was laid in 1957, and consisted of two cables, each transmitting in one direction over 36 channels, with an individual length of 2,625 Nmi (4,862 km). The cable spans between Hanauma Bay, Oahu, Hawaii and Point Arena, California.
