Product Description

1 Scope

This specification defines the optical, mechanical, environmental, and geometrical requirements for simplex single‑mode fiber optic pigtails with SC/APC connectors and 5.0 mm LSZH outer sheath. The pigtail is pre‑terminated with a connector on one end and bare fiber on the other, intended for fusion splicing to optical fiber trunks to enable low‑loss, low‑return‑loss optical signal transmission in high‑speed Ethernet and optical communication systems.
