Fibre optic adapter EFB Elektronik 53344.3 FC/PC Blue Metallic

The EFB Elektronik 53344.3 FC/PC Blue Metallic fibre optic adapter is a single-mode inline adapter designed for reliable optical connections. With an FC/PC connector interface and compact housing measuring approximately 15 mm wide and 11 mm deep, this adapter provides a secure mechanical junction for single-mode fibres where precision alignment and low insertion loss are required. The blue metallic finish adds mechanical protection and makes the adapter easy to identify in patch panels and installation sites.

Advantages

The adapter delivers consistent single-mode performance with FC/PC geometry, supporting stable mating and reduced back-reflection. Its compact form factor saves panel space and allows installation in tight enclosures or distribution frames. The metallic body improves durability and shielding against mechanical stress, while the color coding simplifies identification during maintenance or expansion.

Suitable for

• Single-mode fibre patch panels and distribution frames
• Telecommunications equipment and optical test setups
• Laboratory and field installations requiring FC/PC connections
• Space-constrained enclosures and network cabinets

Key specifications

• Connector type: FC/PC (female inline adapter)
• Mode: Single-mode
• Housing material: Metallic finish for enhanced durability
• Color: Blue metallic
• Dimensions: Approximately 15 mm (width) × 11 mm (depth)
• Mounting style: Inline/adapter coupling for two FC/PC connectors

How to use

Align the FC/PC ferrules of the two single-mode fibre connectors and insert them into each end of the adapter until a secure mechanical fit is achieved. Ensure fibre connectors are clean and free of dust before mating to minimize insertion loss and prevent contamination. For patch panel installation, position the adapter in the designated panel slot or cutout and secure according to the panel’s mounting method. Check optical continuity and signal levels after installation to verify correct alignment and performance.

Recommendations

Regularly inspect and clean connector endfaces with appropriate fibre cleaning tools before mating. Use protective dust caps when the adapter is not in use. Avoid excessive bending or mechanical stress on connected fibres to maintain low insertion loss and long-term reliability.
