Fiber optic ST connector plug Corning UniCam ST E9 SuperPC polish, model 95-200-51

Corning UniCam ST plug model 95-200-51 is an ST-style fiber optic connector featuring an E9 SuperPC polished endface. Designed for use in singlemode and multimode cabling environments, this UniCam ST combines the familiar ST mechanical form factor with Corning's termination design to provide consistent mating, low insertion loss and repeatable connections. The connector is intended for field terminations, patch panels and fiber network repairs where reliable, fast terminations are required.

Advantages

The UniCam ST offers a polished E9 SuperPC endface that reduces back reflection and supports stable optical performance. Its ST-style bayonet coupling delivers secure, repeatable mating and easy alignment during installation. The termination design simplifies field assembly and supports consistent insertion loss values across multiple connections. Materials and geometry are optimized for compatibility with standard fiber jackets and common termination tools.

Suitable for

• Field termination and on-site connectorization of optical fiber
• Patch panels and fiber distribution frames
• Repair and replacement of damaged ST connectors in cabling plants
• Singlemode and multimode network segments requiring SuperPC endface polish

Key specifications

• Connector type: ST-style plug with bayonet coupling
• Endface polish: E9 SuperPC
• Supported fiber types: singlemode and multimode
• Application: field termination, patching, repair
• Optical characteristics: designed for low insertion loss and reduced return loss typical of SuperPC polish
• Compatibility: standard ST adapters and receptacles

How to use

Prepare the fiber by stripping the jacket and cleaving the fiber to the appropriate length according to the termination instructions. Assemble the UniCam ST plug following Corning's field termination procedure: insert the fiber into the connector body, ensure the fiber endface seats correctly against the ferrule, and secure the strain relief. Verify the endface quality with inspection equipment and test optical performance with an optical power meter or light source and power meter to confirm acceptable insertion loss and return loss values.

Recommendations

Use appropriate cleaning and inspection procedures before final mating to avoid contamination. When performing field terminations, follow manufacturer guidance for cleave length, polishing (if applicable), and torque on mating hardware. Store unused connectors in a clean, dry environment and protect endfaces with dust caps until installation.
