Abstract

Disclosed is a buffer tube that possesses a higher buffer-tube filling coefficient. Optical fibers enclosed within the buffer tube demonstrate improved attenuation performance when subjected to temperature variations between about −40° C. and 70° C. The buffer tube is suitable for deployments requiring mid-span access.
