Product information

Description

The Optical Fiber Attenuator CBO SFA23BK25 Singlemode 25 dB is a fixed inline attenuator designed for singlemode fiber networks. It provides a stable 25 dB reduction of optical power to protect receivers from saturation and to equalize link power levels. The compact, passive design requires no external power and is suitable for integration in patch panels, splice enclosures and temporary test setups where predictable attenuation is needed.

Advantages

This singlemode attenuator delivers a precise, fixed attenuation value of 25 dB with low insertion loss variance, ensuring repeatable optical performance. Its robust, compact housing simplifies deployment in confined spaces and rack-mounted environments. Being a passive device, it requires no electrical connection and contributes no additional noise to the optical path. The design supports standard singlemode connectors and is suitable for use in telecom, datacom and laboratory environments.

Suitable for

  • Reducing optical power to prevent receiver overload in singlemode links
  • Power equalization between fiber links in multi-span or multi-channel systems
  • Temporary connection for measurement and testing during installation and maintenance
  • Insertion into patch panels, splice trays or inline fiber assemblies

Key specifications

  • Attenuation: fixed 25 dB
  • Fiber type: singlemode (SM)
  • Operating principle: passive inline attenuator
  • Connector compatibility: standard singlemode connector interfaces (check connector type before installation)
  • Typical applications: telecom, datacom, laboratory testing and fiber installations

How to use

Insert the attenuator inline between two connectorized fiber cables or into the designated port on a patch panel. Ensure connector endfaces are clean and free of dust before mating to avoid additional loss or damage to connectors. Confirm the connector type and polarity match the system requirements. After installation, verify signal levels with an optical power meter or test equipment to confirm expected attenuation and proper system operation.

Usage recommendations

Store the attenuator in a clean, dry environment when not in use and avoid excessive bending of connected fibers. For reliable performance, inspect and clean connectors with appropriate fiber cleaning tools before each connection and verify attenuation with measurement equipment after installation.
