The SC Attenuator from Fibramérica is a high-precision mechanical solution for reducing optical signal power in fiber networks. Available in both UPC and APC polishing types, it provides stable attenuation values ranging from 1dB to 25dB in 1dB increments, making it ideal for testing, balancing, and protecting optical receivers.
Designed in compliance with IEC61754 standards and RoHS directives, this attenuator guarantees consistent performance across a broad wavelength range of 1310nm and 1550nm. It is manufactured with premium-grade materials and offers excellent return loss — ≥50dB for UPC and ≥60dB for APC — ensuring minimal signal reflection and superior transmission stability.
Fibramérica offers both male-to-female (plug-in type) and bulkhead styles to accommodate diverse application needs. Whether in labs, datacenters, or live optical networks, this SC Attenuator is a reliable tool for managing signal levels and protecting sensitive equipment.
