Attenuator EFB Elektronik 533680.10, 45 dB, SC connector, -20–75 °C, 6.3×28.6×10.5 mm

EFB Elektronik 533680.10 attenuator is a compact optical attenuator designed for controlled signal attenuation in fiber optic links. It provides a fixed attenuation value and is suited for insertion in fiber patching or cabling systems that use SC connectors. The unit is built to operate across a wide temperature range and fits into standard cable management setups.

Advantages

The attenuator offers a high attenuation of 45 dB in a small form factor, compatible with SC connectors. Its robust mechanical dimensions (6.3 mm width, 28.6 mm depth, 10.5 mm height) and broad operating temperature range from -20 °C to 75 °C support reliable performance in varied installation environments. Being from EFB Elektronik, it follows established manufacturing quality for fiber optic components.

Suitable for

• Reducing optical power in SC-terminated fiber links
• Laboratory testing and measurement setups requiring precise attenuation
• Integrating into patch panels or inline fiber cabling
• Protecting receivers from receiver overload in high-power links

Key specifications

• Attenuation: 45 dB (fixed)
• Connector type: SC
• Operating temperature range: -20 °C to 75 °C
• Dimensions (W × D × H): 6.3 mm × 28.6 mm × 10.5 mm

How to use

Insert the SC connector of the attenuator into the corresponding SC receptacle of the fiber link or patch panel. Ensure clean connector endfaces before connection to avoid additional insertion loss. The device provides a fixed 45 dB reduction of optical power; no adjustment is required. Secure the attenuator to prevent strain on the fiber and connector during operation.

Recommendations

Clean fiber connectors with suitable cleaning tools before installation and avoid exposing the attenuator to mechanical shock. Select the attenuator only when a fixed 45 dB attenuation is appropriate for the link budget and receiver protection.
