Attenuator EFB Elektronik 533680.2, 45 dB, SC connector, -20–75°C, 6.3×28.6×10.5 mm

EFB Elektronik 533680.2 attenuator is a factory-made optical component designed to reduce signal power in fiber optic links. The attenuator provides a specified attenuation of 45 dB and is built with an SC connector interface. It is intended for insertion into fiber links where controlled signal reduction is required and is rated for operation in the temperature range -20 °C to 75 °C. The compact mechanical dimensions are width 6.3 mm, depth 28.6 mm and height 10.5 mm.

Advantages

The attenuator offers a precise fixed attenuation value (45 dB) and uses a standard SC connector for compatibility with common fiber optic equipment. Its small form factor and wide operating temperature range make it suitable for a variety of installation environments. The product is manufactured by EFB Elektronik with consistent production quality.

Suitable for

• Reducing optical power in singlemode or multimode fiber links where an SC connector is used
• Laboratory measurements and field testing that require a fixed 45 dB attenuation
• Inline insertion in patch panels, distribution frames or test adapters

How to use

Insert the SC connector of the attenuator into the corresponding SC receptacle or adapter in the optical path. Ensure connectors and ports are clean before mating to prevent contamination. Check link power levels before and after insertion to verify the 45 dB attenuation. Secure the attenuator and surrounding cables to avoid strain on the connector during operation.

Recommendations

Use appropriate fiber cleaning tools on connectors before installation, avoid bending the fiber beyond recommended radii near the connection, and store the attenuator in a dry, dust-free environment when not in use. Verify compatibility with the fiber type and system link budget before permanent installation.
