Fibre optic adapter EFB Elektronik B71203.12OM3

The EFB Elektronik B71203.12OM3 fibre optic adapter provides a compact panel-mounted solution for connecting SC-terminated multimode duplex cables. Designed with uncoated contacts and an aqua/grey color scheme, the adapter supports reliable optical mating and straightforward integration into standard 19-inch equipment or custom enclosures. Its external dimensions (483 mm × 244 mm × 44.5 mm) place it in a shallow rack panel form factor suitable for installations where depth is limited.

Advantages

The adapter uses SC connector geometry with uncoated contacts to ensure stable optical alignment and low insertion loss when paired with compatible multimode connectors. The aqua and grey coloring follows common industry coding for multimode OM3 connections, aiding quick identification during installation and maintenance. Its single-unit packaging simplifies inventory handling and reduces waste for smaller projects or targeted replacements.

Suitable for

• Patch panels and rack-mount fibre distribution frames
• Data centre multimode optical links and short-range backbones
• Telecommunications closets and network equipment housings
• Environments requiring compact front-panel optical interfaces

Key specifications

• Connector type: SC
• Contact finish: uncoated contacts
• Multimode profile: compatible with OM3 multimode cabling standards
• Color scheme: aqua and grey for multimode identification
• Unit packaging: single piece
• External dimensions: 483 mm (W) × 244 mm (D) × 44.5 mm (H)

How to use

Mount the adapter into a compatible panel or rack cutout and secure it according to the enclosure manufacturer’s instructions. Insert SC-terminated multimode fibre plugs into the adapter ports until they click into place; ensure the inserted connectors are clean and undamaged to maintain optimal optical performance. For removal, depress the SC connector latch and withdraw the plug straight out to avoid stressing the fibre. Perform loss and continuity testing after installation to confirm correct connections.

Recommendations

Use appropriate fibre cleaning tools before mating fibres and follow established handling procedures for multimode OM3 cabling. Avoid bending fibres near the adapter beyond manufacturer-recommended radii and protect exposed connector endfaces with dust caps when not in use.
