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. [2] Thus, the speed of optical-carrier-classified lines labeled as OC-n is n × 51.84 Mbit/s.
Synchronous Optical Networking ( SONET) and Synchronous Digital Hierarchy ( SDH) are standardized protocols that transfer multiple digital bit streams synchronously over optical fiber using lasers or highly coherent light from light-emitting diodes (LEDs). At low transmission rates data can also be transferred via an electrical interface.
USS Macon (ZRS-5) was a rigid airship built and operated by the United States Navy for scouting and served as a "flying aircraft carrier", carrying up to five single-seat Curtiss F9C Sparrowhawk parasite biplanes for scouting or two-seat Fleet N2Y-1s for training. In service for less than two years, the Macon was damaged in a storm and lost off ...
An optical transport network ( OTN) is a digital wrapper that encapsulates frames of data, to allow multiple data sources to be sent on the same channel. This creates an optical virtual private network for each client signal. ITU-T defines an optical transport network as a set of optical network elements (ONE) connected by optical fiber links ...
Optical coherence tomography. A high-resolution spectral-domain OCT scan (3×3 mm) of a dry age-related macular degeneration eye showing geographic atrophy and drusen in macula on both cross-sectional and en face fly-through. Optical coherence tomography ( OCT) is an imaging technique that uses interferometry with short- coherence-length light ...
The U.S. Navy has also used escort aircraft carriers (CVE, previously AVG and ACV) and airship aircraft carriers (ZRS). In addition, various amphibious warfare ships (LHA, LHD, LPH, and to a lesser degree LPD and LSD classes) can operate as carriers; two of these were converted to mine countermeasures support ships (MCS) , one of which carried ...
