Abstract
An optical fiber coating comprising a thermoplastic rubber block copolymer reduces microbending losses over a wide service temperature range, typically down to at least -40 degrees Celsius, while obtaining an upper temperature limit of typically at least 90 degrees Celsius. The processing properties, including shelf life, cure rate, and toughness, are superior to typical prior art materials, such as silicones. The inventive coating can be used as the inner coating of a dual-layer coated fiber or as an outer or single coating layer.
