Resilient and redundant design
A quick recovery and round-the-clock network is vital for service providers to establish a robust network. The MES-3528 provides comprehensive features
to make sure network is well operated. The IEEE 802.3ad Link Aggregation feature reduces network downtime by providing redundant paths and
bandwidth aggregation to critical connections, while IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) and IEEE 802.1s Multiple Spanning Tree Protocol
(MSTP) allow immediate recovery from failed connections by sending packets via the backup link.
Digital Diagnostics Monitoring Interface (DDMI) SFP support
The enhanced digital interface allows real-time access to device operating parameters, and includes optional digital features such as soft control and
monitoring of SFP I/O signals. In addition, it fully incorporates the functionality needed to implement digital alarms and warnings.
The digital diagnostic monitoring interface enables users to have the capability of performing component monitoring, fault isolation and failure
prediction tasks on their transceiver-based applications.
DDMI Monitors:
• Temperature
• Supply voltage
• Transmitted bias current
• Transmitted power
• Received power
All features listed above include alarm and warning thresholds.
