Product information

Description

EFB Elektronik 533680.5 attenuator is a compact inline optical attenuator with SC connector designed to reduce optical signal power by 45 dB. The device is intended for fiber-optic applications where controlled attenuation is required and is suitable for use across a temperature range from -20 °C to 75 °C. Its small dimensions (6.3 mm × 28.6 mm × 10.5 mm) make it suitable for installation in confined spaces and standard fiber-optic assemblies.

Advantages

The attenuator provides a precise 45 dB attenuation level with SC connectivity, compatible with common single-mode and multimode setups where SC connectors are used. Its metal housing and compact size ensure straightforward integration into inline fiber runs or patch panels. Rated for operation between -20 °C and 75 °C, it is suitable for a wide range of indoor telecom and datacom environments.

Suitable for

  • Reducing optical power in fiber links with SC connectors
  • Laboratory and test setups requiring fixed 45 dB attenuation
  • Inline installation in patch panels and fiber assemblies
  • Environments operating within -20 °C to 75 °C temperature range

How to use

Install the EFB Elektronik 533680.5 attenuator inline by connecting the SC male/female fiber connector to the corresponding SC port in the fiber run or patch panel. Ensure connectors are clean before mating to avoid increased insertion loss or contamination. Once connected, the attenuator provides a fixed 45 dB reduction of optical power; no adjustment or power is required. Secure the inline connection to prevent strain on the connector and avoid bending the fiber beyond its minimum bend radius.

Usage recommendations

Use fiber-cleaning tools to clean SC connectors before installation, store the attenuator in a dry, dust-free environment when not in use, and avoid exposing the device to mechanical shock. Verify system optical power levels after installation to confirm required attenuation and proper link operation.
