Belden Inc. AX105210-S1 Universal St Fiber Optic Connector OM1

Product Description

The BELDEN INC. AX105210-S1 is a universal ST-style fiber optic connector designed for termination on OM1 multimode fiber. ST connectors use a bayonet-style coupling mechanism that locks securely with a quarter-turn, making them a long-standing standard in multimode fiber installations. This connector is sold individually as a single-pack and is appropriate for field termination work performed by low-voltage technicians, network cabling professionals, and experienced electricians working on structured cabling systems. It falls within the fiber modular connectors and inserts product category.

ST fiber optic connectors are commonly used in multimode fiber runs found in commercial buildings, data centers, campus networks, and industrial control environments. OM1 fiber operates at 62.5-micron core diameter and supports shorter-distance Ethernet and network backbone applications. This connector suits new installations as well as repair and re-termination work where an existing ST port is already in service at a patch panel, switch, or wall outlet.

Key Features

• Universal ST-style bayonet coupling for secure, repeatable mating
• Rated for OM1 multimode fiber at 62.5-micron core diameter
• Single-piece pack suitable for individual terminations or small repairs
• Fits the fiber modular connectors and inserts product family for structured cabling applications
• Sold as one unit, allowing precise quantity purchasing for field kits

Compatibility

Designed as an OEM-style field-termination connector for OM1 multimode fiber cabling systems using ST-style ports.

Installation Notes

Installation should be performed by a qualified low-voltage or fiber optic technician following applicable structured cabling standards such as ANSI/TIA-568. Ensure the fiber end-face is properly cleaved and polished before seating the connector to avoid excess insertion loss. Always clean fiber end-faces and mating adapters with approved fiber cleaning tools before making connections. De-energize any active fiber transceivers and follow laser safety precautions before handling open fiber ends.
