Product Description

Product Description

Typical Applications

Product Features

The SC/APC Singlemode Fixed Fiber Optic Attenuator is a plug-in type passive component designed to precisely reduce optical signal power without distorting the signal waveform. With an angled polish connector (APC), it offers low reflection and excellent return loss performance, making it suitable for high-density telecom and data systems.

Available in a full range of attenuation values from 1dB to 25dB, this attenuator is ideal for signal tuning, testing, and system balancing across a wide range of optical platforms.

• Telecommunication switching systems
• CATV optical networks
• FTTH and FTTx signal tuning
• DWDM and CWDM transmission
• Optical test instruments
• Data centers and server rooms
• Patch panels and ODFs
• Network simulation or calibration

• Fixed attenuation range from 1dB to 25dB
• SC/APC male to female plug-in design
• Angled polish for low reflectance
• High return loss ≥60dB
• Compact, durable construction
• Compatible with standard SC interfaces
