Abstract
Optical fibers are coated under pressure to reduce the amount of bubbles entrapped in the coating and provide good coating concentricities. The fiber is drawn axially thru a thin-walled, cylindrical flow distribution sleeve which is located between a guide die and a sizing die. The sleeve contains a plurality of evenly distributed holes the number and size of which is such that radial flow of liquid toward the fiber is maintained over the entire length of the sleeve which is less than 1.27 cm.
