Abstract: A terminator for use with an optical fiber access port structure that supports an optical fiber having an optical end face exposed to communicate with a like end face of another fiber, the terminator comprising a pig-tail-free compact supporting body carrying within itself light-absorbing means and shaped to removably interfit with the access port structure to present the light-absorbing means in light transferring relationship to the exposed end of said optical fiber at the port in manner to absorb incident light from the fiber end face and prevent back-reflection.
