Atenuador BlueOptics SFA21XK10 LC 10 dB preto

The BlueOptics SFA21XK10 LC 10dB Black attenuator is a fixed optical attenuator designed to reduce signal power in multimode fiber links. Intended for 50/125 µm fibers at 850 nm, it uses an LC/UPC simplex connector with a zirconia ceramic ferrule and provides a defined 10 dB attenuation to protect receivers from excessive optical power and to balance power levels across links. The compact black housing and LSZH jacket suit installations in data centers, telecom racks and structured cabling where controlled attenuation and low smoke/harmful gas emissions are required.

Advantages

The attenuator delivers a stable 10 dB attenuation with low additional insertion loss and high return loss. Constructed with branded fiber and precision connectors, it is tested using interferometer and OTDR methods and supplied with a measurement protocol for input loss and return loss. The zirconia ferrule and quality connector components support long mating cycle life, while the LSZH jacket provides reduced smoke and no halogen release in fire conditions. The unit is specified to operate across a wide temperature range suitable for industrial and commercial environments.

Key specifications

How to use

Insert the LC/UPC simplex connector of the attenuator between the transmitter and the receiver or patch panel port requiring reduced optical power. Ensure connectors and ports are clean before mating to prevent contamination-related loss. The attenuator provides a fixed 10 dB reduction immediately upon insertion; no configuration is required. After installation, verify optical power levels with a power meter or OTDR to confirm that receiver input remains within safe operating range.

Recommendations

Use this attenuator in-line on multimode LC connections where measured optical power exceeds receiver specifications. Store and handle connectors with protective caps until installation, periodically inspect mating surfaces for contamination, and replace the attenuator if physical damage or abnormal loss is detected. For systems requiring different attenuation values or APC polish, select the appropriate variant to match link requirements.
