Satellite means any satellite owned by, or leased to, the Borrower or any of its Restricted Subsidiaries and any satellite purchased pursuant to the terms of a Satellite Purchase Agreement, whether such satellite is in the process of manufacture, has been delivered for launch or is in orbit (whether or not in operational service).
Filter means material placed in the useful beam to preferentially absorb selected radiations.
Spectrum Compatibility means the capability of two (2) copper loop transmission system technologies to coexist in the same cable without service degradation and to operate satisfactorily in the presence of cross talk noise from each other. Spectrum compatibility is defined on a per twisted pair basis for specific well-defined transmission systems. For the purposes of issues regarding Spectrum Compatibility, service degradation means the failure to meet the Bit Error Ratio (BER) and Signal-to-Noise Ratio (SNR) margin requirements defined for the specific transmission system for all Loop lengths, model Loops, or loss values within the requirements for the specific transmission system.
Beam monitoring system means a system designed and installed in the radiation head to detect and measure the radiation present in the useful beam.
