Attenuator EFB Elektronik 533680.1, 45 dB, SC connector, -20–75 °C, 6.3×28.6×10.5 mm

EFB Elektronik 533680.1 attenuator is a compact optical attenuator designed to reduce signal power in fiber optic links. Manufactured by EFB Elektronik, this inline attenuator provides 45 dB attenuation with an SC connector and is suitable for use across a wide temperature range from -20 °C to 75 °C. Its small dimensions (6.3 mm width, 28.6 mm depth, 10.5 mm height) make it suitable for installation in confined spaces and standard fiber optic assemblies.

Advantages

The EFB Elektronik 533680.1 offers a high, precise attenuation level of 45 dB in a compact form factor and uses an industry-standard SC connector. It is specified to operate reliably over a broad temperature range (-20 °C to 75 °C) and is produced by a manufacturer with experience in fiber optic assemblies, ensuring consistent build quality.

Suitable for

• Reducing optical signal power in single-mode links
• Integration into patch panels and fiber distribution frames using SC interfaces
• Laboratory measurements and testing where fixed high attenuation is required
• Environments with moderate temperature variation within the specified range

How to use

Install the attenuator inline between two SC-terminated fiber connectors or in an adapter panel that accepts SC connectors. Ensure connectors are clean before mating to avoid contamination and insertion loss unrelated to attenuation. Verify the required 45 dB attenuation for your application and confirm link performance with appropriate test equipment after installation.

Recommendations

Handle the attenuator with care to avoid damaging the connector ferrule. Keep protective caps on unused connectors when the device is not installed. For reliable operation, use within the specified temperature range and verify end-to-end loss with an optical power meter or OTDR as appropriate.
