Atténuateur BlueOptics SFA21XK1 LC 1dB argent

The BlueOptics SFA21XK1 LC 1dB Silver attenuator provides a fixed 1 dB reduction of optical signal power for multimode (50/125 µm) fiber links at 850 nm. Fitted with an LC/UPC simplex connector and a zirconia ceramic ferrule, this inline attenuator is intended to control excess optical power on short links and preserve receiver performance without altering transmission characteristics. The product is designed with a silver finish and a low insertion loss construction, and is factory-tested to document input loss and return loss values.

Advantages

The attenuator offers precise 1 dB attenuation while maintaining low input loss and high return loss, helping to avoid receiver saturation. High-quality components such as branded optical fiber and ceramic ferrules ensure consistent optical performance and mechanical reliability. Each unit is tested using interferometry and OTDR and supplied with a measurement protocol, and the component is constructed to meet industry safety and durability standards.

How to use

Install the BlueOptics SFA21XK1 in-line between the transmitting and receiving devices using the LC/UPC connectors. Ensure connectors and ports are clean before mating to avoid contamination-related loss. Insert the attenuator into the patch cord or patch panel port until fully seated; the unit is designed for standard LC housings and simplex connections. After installation, verify optical power levels and confirm the receiver operates within its specified input range.

Recommendations

For reliable results, clean connector end faces with an appropriate fiber cleaning tool before each connection, keep mating cycles within the specified lifetime of the connector, and confirm attenuation with a calibrated power meter. Use LSZH-rated cabling in environments where low smoke and halogen-free properties are required.
