AMERICAS-II
AMERICAS-II is a fiber optic submarine communications cable that carries telecommunications between Florida, the U.S. Virgin Islands, Puerto Rico, Martinique, Curaçao, Trinidad and Tobago, Venezuela, French Guiana, Suriname and Guyana (both through Cayenne), and Brazil. It has been in service since August 2000 and is operated on a common carrier basis. AMERICAS-II consists of three interconnected rings (North, South, and West Systems), each operating at 2.5 gigabits per second ( Gbit/s), initially in separate collapsed ring configurations, and a dedicated link between Curaçao and Venezuela not operating in a collapsed ring configuration. Each fiber pair in each of the three systems will have a capacity of thirty-two 155 megabits per second ( Mbit/s) OC-3 Basic System Modules (BSM), with each BSM containing 63 Minimum Investment Units (MIUs) and equipped at the outset for a capacity of 1008 MIUs. Its initial total rate of 40 Gbit/s increased in 2009 to 160 Gbit/s and again 2010 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiber Optic
An optical fiber, or optical fibre in Commonwealth English, is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair. Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables. Fibers are used instead of metal wires because signals travel along them with less loss; in addition, fibers are immune to electromagnetic interference, a problem from which metal wires suffer. Fibers are also used for illumination and imaging, and are often wrapped in bundles so they may be used to carry light into, or images out of confined spaces, as in the case of a fiberscope. Specially designed fibers are also used for a variety of other applications, some of them being fiber optic sensors and fiber lasers. Op ...

OC-3
Optical Carrier transmission rates are a standardized set of specifications of transmission bandwidth for digital signals that can be carried on Synchronous Optical Networking (SONET) fiber optic networks. Transmission rates are defined by rate of the bitstream of the digital signal and are designated by hyphenation of the acronym OC and an integer value of the multiple of the basic unit of rate, e.g., OC-48. The base unit is 51.84 Mbit/s. Thus, the speed of optical-carrier-classified lines labeled as OC-n is ''n'' × 51.84 Mbit/s. Optical Carrier specifications Optical Carrier classifications are based on the abbreviation ''OC'' followed by a number specifying a multiple of 51.84 Mbit/s: ''n'' × 51.84 Mbit/s => OC-''n''. For example, an OC-3 transmission medium has 3 times the transmission capacity of OC-1. OC-1 OC-1 is a SONET line with transmission speeds of up to 51.84 Mbit/s (payload: 50.112 Mbit/s; overhead: 1.728 Mbit/s) using optical fib ...

Miramar, Puerto Rico
Miramar is one of the forty subbarrios of Santurce, San Juan, Puerto Rico. It has many Spanish-style homes with patios and gardens. History The neighborhood is under the legal jurisdiction of Santurce in the municipality of San Juan, Puerto Rico. It first appears in the 16th century as a spring that fed water to the Spanish outpost of Old San Juan. In the 17th century a wide public street, the Central Highway, (today Ponce de León Avenue) was built that ran through the spring. Commerce flourished since goods that arrived at the port of San Juan had to pass Miramar on their way to the rest of the island. Today two set of bridges known as San Antonio and Dos Hermanos connects the adjoining areas of Old San Juan and Condado. Its land area measures 0.24 sq. miles (0.62 km²), and has a resident population of 5,440 according to the 2000 United States Census. Miramar, since its beginnings had large wooden plantation-style homes with expansive land lots. In the 1950s well ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chaguaramas, Trinidad
Chaguaramas (pronounced, in the local English dialect, "shag-gah-rah-muss") lies in the Northwest Peninsula of Trinidad west of Port of Spain; the name is often applied to the entire peninsula, but is sometimes used to refer to its most developed area. The developed area in Chaguaramas starts at ALCOA and ends at the Army and Coast Guard camps on the mainland.
