A tight buffered optical fiber and methods of manufacturing the same include an optical fiber and a tight buffer layer. The tight buffer layer has a predetermined wall thickness generally surrounding the optical fiber and at least one preferential tear portion generally formed along a longitudinal axis of the tight buffer layer. In one embodiment, the tight buffered optical fiber has a delta attenuation of about 0.300 dB/km or less at a temperature of about -40 C. at a reference wavelength of about 1550 nm, thereby making the tight buffered optical fiber suitable for outdoor environments. Other embodiments can include a buffer layer surrounding one or more optical fiber ribbons. In other embodiments, the buffer layer can be formed from a material having an elongation to break ratio of about 500% or less.
