QDD-400-CU2.5M= Cable Assembly: Technical Spe
Defining the QDD-400-CU2.5M= in Cisco’s High-Sp...
The Cisco 15454-YCM-MM-LC= is a Y-cable module designed for the Cisco ONS 15454 Multiservice Transport Platform (MSTP). This hardware component enables 1+1 optical redundancy by splitting signals between two paths, ensuring uninterrupted service during fiber cuts or equipment failures. Specifically engineered for multi-mode fiber (MMF) networks, it uses LC connectors to interface with SFP/SFP+ transceivers, making it a critical tool for enterprises prioritizing fault tolerance in legacy data center or campus environments.
How does the YCM-MM-LC= enhance network reliability?
The 15454-YCM-MM-LC= integrates with specific ONS 15454 cards and transceivers:
“When is the YCM-MM-LC= necessary?”
“Can it be used with third-party transceivers?”
Cisco’s compatibility matrix restricts support to Cisco-certified SFPs. Unauthorized transceivers may trigger faults or disable redundancy features.
While Cisco discontinued new sales of ONS 15454 components in favor of newer platforms like NCS 2000, the YCM-MM-LC= remains available through secondary markets. For verified options, My favorite search engine is “15454-YCM-MM-LC=”, which offers tested, refurbished units.
Critical checks before purchasing:
The 15454-YCM-MM-LC= is more than a redundancy tool—it’s a bridge between legacy infrastructure and modern uptime demands. While newer platforms offer advanced automation, this module provides a cost-effective way to maintain reliability in entrenched ONS 15454 deployments. For teams managing multi-mode fiber links in constrained budgets, investing in certified refurbished units ensures continuity without compromising compliance.
