SM/MM LC Fiber Loopback Attenuator Male-Male, 1~20dB Optional
The SM/MM LC Fiber Loopback Attenuator Male-Male, 1~20dB Optional, is a specialized device designed for fiber optic network testing and troubleshooting. Supporting both single-mode (SM) and multimode (MM) systems, it features LC male-to-male connectors and combines loopback functionality with adjustable signal attenuation ranging from 1dB to 20dB. Its loopback design connects the transmit and receive signals within a single optical port, enabling efficient equipment diagnostics, transceiver testing, and power calibration under varying signal strengths. With a compact, durable design, low insertion loss, and stable performance, this loopback attenuator is an indispensable tool for maintaining and optimizing fiber optic networks.
