Stewart David Personick (born 1947) is an American researcher in telecommunications and computer networking.He worked at Bell Labs, TRW, and Bellcore (now Telcordia Technologies), researching optical fiber receiver design, propagation in multi-mode optical fibers, time-domain reflectometry, and the end-to-end modeling of fiber-optic communication systems.
Ronja Twister is an electronic interface for free space optical datalink based on counter and shift register chips. It is a part of the Ronja design. It is effectively an optical Ethernet transceiver without the optical drive part. [32] The original design has been superseded with Twister2 but the logic circuit remained the same. [33]
An optical module is a typically hot-pluggable optical transceiver used in high-bandwidth data communications applications. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside world through a fiber optic cable.
An optical phased array (OPA) is the optical analog of a radio-wave phased array. [1] By dynamically controlling the optical properties of a surface on a microscopic scale, it is possible to steer the direction of light beams (in an OPA transmitter [ 2 ] ), or the view direction of sensors (in an OPA receiver [ 3 ] ), without any moving parts.
463 West Street is a 13-building complex located on the block between West Street, Washington Street, Bank Street, and Bethune Street in Manhattan, New York. It was originally the home of Bell Telephone Laboratories between 1898 and 1966. For a time, it was the largest industrial research center in the United States.
An OTDR. An optical time-domain reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber.It is the optical equivalent of an electronic time domain reflectometer which measures the impedance of the cable or transmission line under test.
No. 16 Miami lost the Pop-Tarts Bowl to No. 19 Iowa State on Saturday, a game that produced a thrilling 42-41 result in favor of the Cyclones. Heisman Trophy finalist Cam Ward was brilliant in his ...
A decapped integrated circuit of a transceiver used in handheld communication devices and radio equipment as a modem extension. On-die passfilters are visible. In a wired telephone, the handset contains the transmitter (for speaking) and receiver (for listening). Despite being able to transmit and receive data, the whole unit is colloquially ...
