Keep critical fiber links visible without putting the production path at risk. This Progress Software LC tap is designed for 50/125 multi-mode fiber and uses a 70/30 split ratio, sending most of the optical signal through the main line while diverting a smaller portion to monitoring equipment. That balance matters when you need dependable packet capture, troubleshooting, or traffic analysis on active infrastructure. A 70/30 split helps maintain stronger throughput on the primary circuit than a more aggressive tap ratio, making it a practical choice for environments where link integrity comes first and visibility still has to be good enough for diagnostics. Built for LC-based multi-mode deployments, this tap fits naturally into fiber monitoring architectures where passive access is preferred over inline disruption. It is a focused hardware accessory for teams that need to observe traffic, validate performance, and isolate issues without introducing another active device into the path.
