Cisco PON Switches Models:

Features and Benefits:

The passive element is stable and easy to maintain without failure.

• All-Optical has high bandwidth and great potential for bandwidth upgrade in the future, which is the development trend of bearer networks.
• Simple Network, load balancing, and end-to-end network management for easy maintenance.

High Performance

• The platform adopts an all-optical network, which has a large bandwidth capacity for carrying multiple services. It has good expansibility and network upgrade space, which is in line with the network development trend.
• Large bandwidth, the maximum bandwidth of a single user can reach 2500Mbps.
• One fiber carries multiple services, supporting voice, video, security, Internet, and other services.

High Reliability

• Support type B protection, backup, and disaster recovery protection for PON port.
• Power redundancy and dual uplink routing to avoid a single point of network failure.
• IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) provides rapid spanning-tree convergence independent of spanning-tree timers and also offers the benefit of Layer 2 load balancing and distributed processing.
• IEEE802.3AD Link Aggregation Control Protocol (LACP) provides multiple links binding to achieve uplink backup.

QoS

• The platform provides end-to-end QoS guarantees. Through the comprehensive application of congestion management, priority marking, queue scheduling, and traffic rate limiting/shaping, it can meet the user’s service quality requirements and create a high-quality network for customers.
• Service quality guarantee: Based on the IEEE 802.1p protocol, different service class CoS (Class of Service) values are set according to different service types, and differentiated priority processing methods are provided to improve the network quality index such as delay time, jitter, and packet loss rate. Different traffic classifications have different priorities, and different queues such as SP (Strict Priority) and WRR (Weighted Round Robin) are used to perform queue scheduling of data flows for improving the quality of the services.
• Bandwidth guarantee: User bandwidth is guaranteed by the application of the DBA (Dynamic Bandwidth Assignment) mechanism and the traffic rate limiting/shaping function. Generally, the VoIP service is set to a fixed bandwidth, the IPTV and video services are set to ensure bandwidth, and the high-speed Internet service is set to the maximum bandwidth. The data stream is limited and shaped by a plurality of line templates to ensure bandwidth guarantee.
