Fibre Optic Connector ST Qoltec 54435 Multi-mode Silver 200 pcs

The Qoltec 54435 ST fibre optic connector in silver is designed for multi-mode fibre applications and is supplied in a pack of 200 pieces. These connectors provide a bayonet-style ST coupling with a spring retention that secures the fibre and ensures stable mechanical contact. The compact packaging dimensions (20 mm width, 100 mm depth) make the set convenient for storage and distribution when preparing multiple terminations for LANs and other short-distance optical networks.

Advantages

The ST Qoltec 54435 offers consistent mechanical alignment with a ceramic ferrule that reduces insertion loss and maintains low attenuation in multi-mode systems. The bayonet coupling allows quick insertion and reliable retention, which speeds up installation and repeatable connections. Supplied in bulk (200 pcs), the pack is suitable for installers and integrators who need multiple identical connectors for parallel terminations or replacement stock.

Suitable for

• Multi-mode fibre patching in local area networks (LAN)
• Spare parts for fibre optic panels and wall outlets
• Mass termination projects and cabling deployments
• Field installation and maintenance where ST interfaces are required

Key specifications

• Connector type: ST (bayonet)
• Fibre type: Multi-mode
• Material: metal housing with ceramic ferrule
• Colour/finish: silver
• Pack quantity: 200 pieces
• Typical use: simplex terminations for patch panels and patch cords
• Package dimensions: approximately 20 mm width × 100 mm depth

How to use

Prepare the multi-mode fibre by stripping, cleaning, and cleaving the fibre end according to standard termination procedures. Slide the ST connector parts onto the prepared fibre, insert the fibre into the ceramic ferrule until it seats firmly, then secure the connector following the manufacturer's assembly steps for crimp or adhesive types as applicable. After assembly, inspect the endface and use appropriate cleaning methods and a visual fault locator or optical power meter to verify low loss and correct alignment before deploying the cable in the network.

Recommendations

Store connectors in their original packaging until use to avoid contamination. Use lint-free wipes and isopropyl alcohol for cleaning ferrules and endfaces. For repeatable performance in multi-mode networks, ensure polish quality and ferrule cleanliness; when replacing connectors on existing links, test insertion loss to confirm performance meets system requirements.
