The E7-20 Ethernet Service Access Platform (ESAP) represents a new generation of high capacity Ethernet access solutions. Designed for IP over glass and "an all-video world," the E7-20 seamlessly delivers existing fiber technologies (GPON, AE / point-to-point GE). At release, the E7-20 will serve up to 480 dedicated Active Ethernet subscribers or 5,120 GPON subscribers – with sufficient headroom to accommodate 20,000 subscribers through the introduction of higher density and higher capacity line cards in the future.
Key E7-20 features:
- 2 terabit backplane, 100 Gbps to each slot
- Optimized for fiber-based greenfield data center and CO deployments
- Centralized switching controllers that deliver fully redundant, carrier grade performance
- At release, will serve 480 AE or 5,120 GPON subscribers, with the capacity to serve over 20,000 in the future
- Capacity to deliver emerging fiber technologies (10G PON, 10GE aggregation, 100GE uplinks / transport)
Key Ethernet Protocols, Features & Management Functionality
- 200 Gbps switching capacity on centralized switching control processor (SCP)
