Manufacturer's Description

The EXFO EUI-91 is an SC-type connector adapter for use with EXFO's Universal Interface (EUI) system, fitted as standard to EXFO OTDR, OSA, and light source optical ports.

EXFO's Universal Interface (EUI) was the industry's first built-in interchangeable connector system, allowing technicians to quickly swap connector types in the field without tools. The EUI-91 provides an SC connector interface and is compatible with both UPC (non-angled) and APC/EA (angled) polished fibre ends. The adapter separates from the fixed baseplate via a simple push-and-turn action, giving immediate access to the ferrule for cleaning and maintenance.

Key Features:
Connector Type: SC
Polishing Compatibility: UPC (non-angled / EI) and APC (angled / EA)
Mounting: Twist-on EUI baseplate system
Dust Protection: Hinged protective cap
Body Material: Stainless steel
Compatible Instruments: All EXFO OTDR models, OSA ports, and light source (LS) ports including FTB-1, FTB-2, MAX-700 series, MAX-800, AXS-100, AXS-110, FiberBasix 100 Series, FiberBasix 500 Series
Available EUI Series Types: FC (EUI-89), ST (EUI-90), SC (EUI-91), DIN47256, HMS-10/AG, E-2000

The EUI system ensures repeatable optical connections and simplified maintenance, making connector type changes fast and reliable in field and lab environments.
