Abstract:
An optical fiber cable and a tight-buffered optical fiber which suppress an increase in transmission loss in a humid and hot environment and have good manufacturability are disclosed. The tight-buffered optical fiber of the present invention comprises a glass fiber surrounded by a first coating layer and a second coating layer, the second coating layer comprising two or more layers; wherein a pull-out force is 15 N/20 mm or less in at least one pair of layers between the first coating layer and the second coating layer, or between any two layers of the second coating layer.
