Polymer versus silica fibers

Sihca fibers are stiU unsurpassed as regards attenuation and bandwidth, but their diameter has to be kept rather small to provide for the required cable flex-ibihty. Consequently, sldUfiil hands and high precision tools are required to connect sihca fibers in a time-consuming process. Polymer fibers have a much low-
