Abstract

The present disclosure provides an optical fiber cable (100). The optical fiber cable (100) includes a first layer (108) and a second layer (110). The second layer (110) surrounds the first layer (108). The first layer (108) includes a first plurality of buffer tubes (122). The second layer (110) comprises a second plurality of buffer tubes (124). Each buffer tube of the first plurality of buffer tubes (122) and the second plurality of buffer tubes (124) has a thickness of at most 0.15 millimeter. Each buffer tube of the first plurality of buffer tubes (122) and the second plurality of buffer tubes (124) includes a first material layer (126) and a second material layer (128). The second material layer (128) surrounds the first material layer (126). The first material layer (126) is made of polybutylene terephthalate. The second material layer (128) is made of polycarbonate.
