WAVELENGTH Clause Samples
The 'Wavelength' clause defines the specific frequency range or band within the electromagnetic spectrum that is covered or regulated by the agreement. In practical terms, this clause may specify which wavelengths are permitted for use, transmission, or allocation, such as in telecommunications, broadcasting, or scientific research contexts. By clearly delineating the applicable wavelength, the clause helps prevent interference, ensures compliance with regulatory standards, and allocates usage rights, thereby reducing disputes and promoting efficient spectrum management.
WAVELENGTH. A. Exodus acknowledges that (i) the circuits used for the Wavelength Services are not protected by a restoration protocol within or external to the SONET frame structure, (ii) Global Crossing will not provide Wavelength Services using conventional SONET TDM add/drop multiplexers using a BLSR or UPSR or linear restoration protocol within or external to the SONET frame structure, and (iii) the interoperability of the individual circuits is dependent upon the joint interconnection of the interface between Global Crossing’s WDM system and Exodus’s source systems and facilities. Exodus’s source systems will operate within the conventional 1310nm and 1550nm passbands, using Short Reach, Intermediate Reach, or Long Reach optic, as defined in Telcordia GR-253-CORE. Except with Exodus’s prior written consent, Global Crossing will provide the Wavelength Services solely over Global Crossing’s facilities-based TDM / WDM network and fiber, equipment or other WDM service(s) owned or controlled by Global Crossing and its Affiliates.
B. The Wavelength Services will be configured as follows:
WAVELENGTH. The refractive index detector must feature a LED with the same wavelength as the laser in the light scat-tering detector. Additionally, the wavelength of the dRI instrument must be changeable by the user; LEDsor other light sources must be available in order to change the wavelength of measurements in a matterof minutes to 660 nm, 690 nm, 633 nm, 488 nm and other standard values.
