DELOCK fiber optic coupling HFBR 4505Z simplex blue to blue, plastic housing, model 91041

DELOCK fiber optic coupling HFBR 4505Z simplex blue to blue in a plastic housing (model 91041) is a compact inline adapter designed to join two simplex HFBR-style fiber terminations. The coupling provides a simple feed-through connection for single-fiber links, enabling extension or repair of fiber runs in communication and data environments. Its plastic housing and straightforward mating interface make it suitable for panel installation or use as a small-space splice point where two HFBR connectors must be connected reliably.

Advantages

This HFBR 4505Z simplex coupling offers a compact form factor and tool-free mating for quick inline connections between two HFBR simplex terminations. The plastic housing reduces weight while providing a defined alignment for the blue-to-blue connection, helping to maintain optical continuity for single-fiber links. The adapter is suitable for use in confined spaces and for simple installation on panels or into feed-through positions.

Suitable for

• Joining or extending two HFBR simplex fiber terminations
• Panel-mounted feed-through connections for single-fiber links
• Inline repairs or temporary fiber connections in communication equipment
• Applications where a compact, lightweight plastic coupling is required

When it may not be suitable

This coupling is intended for simplex HFBR-style connectors and is not suitable for multimode connectors with different ferrule types or for duplex fiber systems that require two-fiber alignment in a single body. It does not provide enhanced environmental sealing or ruggedized mechanical protection, so it may not be appropriate for harsh outdoor installations or where IP-rated enclosures are required.

Key specifications

• Type: simplex fiber optic coupling
• Connector interface: HFBR-style female to female (blue to blue)
• Housing material: plastic
• Color: blue-to-blue mating (housing noted as grey in manufacturer materials)
• Mounting: suitable for panel/feed-through installation
• Quantity: single unit

How to use

Align the HFBR simplex connectors from each fiber cable with the female ports of the coupling and push them in until they seat securely. If mounting to a panel, position the adapter in the feed-through cutout and secure it according to the panel or chassis design. Verify optical continuity after installation with appropriate test equipment. For inline repairs, ensure connector endfaces are clean and free of debris before mating to maintain low insertion loss.

What to consider before purchase

• Compatibility with the specific HFBR-style simplex connectors used in your system
• Requirement for simplex (single-fiber) versus duplex connections
• Environmental conditions and whether a sealed or ruggedized coupling is needed
• Panel or chassis cutout dimensions if you plan to mount the coupling

Usage recommendations

Use fiber cleaning tools to remove dust and contaminants from connector endfaces before mating and perform a continuity or insertion loss test after connection. Store unused couplings in a clean, dry environment and avoid excessive bending of fibers at the coupling to preserve optical performance.
