Abstract: A compression-expandable plug provides lateral expansion of an elastomeric gasket to seal around mini-tubes within an optical fiber duct, the mini-tubes containing optical fibers. The compression-expandable plug includes an elastomeric gasket having longitudinal passages configured to be positioned around optical-fiber-containing mini-tubes in an optical fiber duct and means for longitudinally compressing the gasket thereby laterally expanding it to exert sealing pressure around the mini-tubes and between the mini-tubes and the duct. A means for limiting the longitudinal compression applied to the gasket to limit the sealing pressure to a level selected to limit damage to the optical fibers may be provided.

Abstract: A sealant-filled connector assembly for use with a connector plug includes a connector housing including a unitary body portion defining a body cavity and at least one conductor passage extending through the unitary body portion and communicating with the body cavity. The connector housing defines a connector opening communicating with the body cavity. The connector opening is adapted to receive the connector plug. An electrical conductor extends through the at least one conductor passage and has a contact portion disposed in the body cavity. An environmental sealant is disposed in the body cavity up to a sealant fill level and at least partially covering each the contact portion. The unitary body portion is devoid of openings other than the at least one conductor passage up to at least the sealant fill level.
