Performance assessments in analog video transport and distribution will be compared and analyzed, based on existing commercial optical and electronic equipment used with a variety of standardized optical fiber types. Particular emphasis is placed on comparison of capabilities with standard single-mode fiber to improve SBS thresholds on the order of 2dB, with associated increases in CNR, as well as improvements in CSO on the order of 8-9dB. Experimental and simulated results will be presented, in addition to recent field data collected from actual physical links deployed by a major MSO. This is the first known commercial deployment of an alternate optical fiber type (i.e., not standard singlemode) expressly for the purposes of improving analog video transport capability.
