12core MTP® APC Single Mode OS2 Loopback Green connector with 15DB maximum

Product Overview

The 12-core MPO/APC loopback module is engineered for high-performance optical network testing and simulation. Designed for single-mode applications, this loopback features angled physical contact (APC) polishing and offers a fixed maximum attenuation level of 15 dB, simulating real-world signal loss in data center, telecom, and equipment testing environments.
