Kuituadapteri BlueOptics SFA21BK1 LC-pistoke sininen

The BlueOptics SFA21BK1 LC Connector Blue is a single-mode fibre optic attenuator with an LC/PC simplex connector and a blue housing. Designed for single-mode 9/125 µm fibres (G.652.D) and specified for wavelengths from 1270 nm to 1610 nm, this attenuator provides a fixed 1 dB attenuation to reduce optical power where required. The product uses a zirconia ceramic ferrule for reliable mating and is RoHS compliant. It is suitable for short-distance links and installations where excessive input power must be lowered to avoid receiver overload. Each unit is tested after production and shipped with a measurement protocol documenting input loss and return loss.

Advantages

The BlueOptics SFA21BK1 offers a stable and predictable 1 dB attenuation with low input loss and high return loss. Its LC/PC connector and high-quality ceramic ferrule ensure consistent mating durability and low back-reflection. Manufacturing uses branded optical fibre and connectors, and finished units are verified with interferometer and OTDR testing. The attenuator is rated for wide operating temperatures and features an LSZH jacket for reduced smoke and no halogen release in case of fire.

Suitable for

• Reducing optical signal power in single-mode fibre links
• Preventing receiver saturation on short-distance connections
• Laboratory testing and optical power management
• Telecommunications and data centre patch panels using LC connectors

How to use

Insert the LC/PC connector into an LC adapter or port, ensuring correct alignment and a clean connector end-face before mating. Use this fixed 1 dB attenuator inline between the transmitting fibre and the receiver or patch panel to reduce optical power. Avoid excessive dust and contamination by keeping protective caps on when the attenuator is not in use and clean connectors with appropriate fibre cleaning tools if needed. Do not exceed the specified operating temperature range and avoid mechanical stress on the fibre and connector.

Recommendations

Confirm the required attenuation level for your installation before fitting the attenuator; for higher attenuation needs, select the appropriate staged attenuator. Regularly inspect and clean connector end-faces to maintain low insertion loss and high return loss. Store unused attenuators in protective packaging to preserve the ferrule and connector integrity.
