Set of 10 FC/A attenuation elements (mixed male and female FC/A connectors) with varying attenuation levels: 0 dB, 3 dB, 10 dB, 12 dB, 15 dB, 20 dB, 7 dB and 5 dB. Designed to reduce signal power in fiber optic systems to meet link loss budgets and protect receivers. Compatible with FC/A connectors for easy installation and integration into existing FC/A lanes. Fixed FM attenuator with a flange for secure mounting and reliable connection. Key benefits - Enables precise optical level control to optimize link performance - Helps protect sensitive receivers by preventing overload - Simple to specify and implement in FC/A based installations - Flange-mount design offers secure, stable attachment Typical use scenarios - Commissioning and maintenance of fiber links to trim downstream power and balance channel levels - Test and measurement setups to simulate different fiber losses for equipment testing - Field deployments where consistent attenuation is needed across multiple links or channels
