High-Performance, Low-Reflectance Low-Loss Mechanical Splices

All experience substantiates that Rotary mechanical splices are completely usable in both digital and analog optical systems. This means that the unique and desirable features of lowest loss, re-enterability and rearrangeability are possible everywhere. Insertion loss and return loss data are presented for four different AM-analog CATV installations that use Rotary splices. In the first of these, Rotary splices, that are polished with 10°-angled ends, are directly compared to fusion. OTDR traces are shown to be the same for both splice types. Furthermore, differences between the two splices for system carrier-to-noise and intermodulation values are indistinguishable.
