Optical-fiber cable connectivity in the horizontal has been deterred due to the excessive cost associated with the optical interface at the computer desktop.
Optical-fiber cable offers the greatest bandwidth, as well as robust mechanical and environmental performance.
The inherent advantages of optical-fiber cable still exist, even in spite of the introduction of CAT 6 copper cables.
We describe the results of a comparison of reference standards between the National Institute of Standards and Technology (NIST-USA) and Physikalisch-Technische Bundesanstalt (PTB-Germany) at nominal wavelengths of 1300 nm and 1550 nm using an optical-fiber cable. Both laboratories used thermal detectors as reference standards.
The same lasers, operating at 1302 nm and 1546 nm, and optical-fiber cable were used at both sites.
2 consists of fiber-pigtailed laser sources at wavelengths of 1302 nm and 1546 nm, a reference optical-fiber cable, and a positioning stage for comparing the NIST reference and transfer standards.
But a broken optical-fiber cable forced researchers atop the 3,790-meter Antarctic peak to abandon their efforts late last week after Dante had barely crept over the rim of the volcano's outer crater.
The robot has two spools at its rear that play out an optical-fiber cable linking Dante's onboard sensors and motors with its "brain," the computers that provide its depth perception and ability to self-navigate.
To rectify the problem, communications engineers install "repeaters" along the optical-fiber cable to clean up and amplify the degraded signal.
Because solitons furnish an extremely clean signal that remains virtually unchanged over tens of kilometers, optical-fiber cables carrying them convey a much larger volume of data and require fewer repeaters than systems now in use.
The fuse phenomenon may have implications for the designs of optical-fiber cables
needed for communication and data transfer among spacecraft instruments.
