ST* Epoxy Bayonet Connector for
Multimode/Single-mode

Bayonet design

Quick interconnect

Keyed connector

Assures high repeatability

Pre-radiused PC ferrule

Assures contact of fibers; low 
reflection, consistent performance

Zirconia ceramic ferrule

Durability; stability through 
temperature change; quality 
performance

The Epoxy ST* Connector is bayonet style for quick
interconnect and high repeatability.
