The Optical Fiber Attenuator CBO SFA23BK10 10 dB Singlemode ST Simplex is a passive inline device designed to provide a fixed 10 dB signal reduction in singlemode fiber links. It uses an ST simplex connector interface and is intended to balance optical power levels between transceivers and receivers, preventing receiver saturation and ensuring stable link performance in laboratory, testing and installation environments.

Advantages

This fixed 10 dB attenuator offers a simple, reliable method to lower optical power without power source or configuration. Its ST simplex form factor is compatible with equipment using ST connectors and enables quick insertion into existing singlemode fiber links. The passive design delivers predictable attenuation across standard singlemode wavelengths and reduces the need for electronic gain control when connecting high-power optics to sensitive receivers.

Suitable for

  • Laboratory testing and measurement of singlemode fiber systems
  • Field installations where optical power must be reduced to meet receiver input limits
  • Temporary link adjustments during commissioning or troubleshooting
  • Protecting receivers from saturation when connecting high-power transceivers

Key specifications

  • Attenuation: fixed 10 dB
  • Fiber type: singlemode
  • Connector type: ST simplex
  • Operation: passive inline attenuator
  • Typical insertion loss tolerance: defined for fixed attenuators at specified wavelength ranges

How to use

Insert the attenuator inline between the transmitting device and the receiver using compatible ST simplex connectors. Ensure connectors are clean before mating to avoid contamination and increased loss. After insertion, verify optical power levels at the receiver to confirm the expected 10 dB reduction and adjust cabling or additional attenuation as required. The device requires no power or configuration and can remain installed as part of a permanent or temporary link.

Recommendations

Inspect and clean ST connector endfaces with appropriate fiber cleaning tools before use; avoid bending the fiber sharply at the connector interface. Use this attenuator for singlemode wavelengths and check power budgets after installation to ensure sufficient margin at the receiver.
