To reduce costs and lower power consumption, the CS8120 OLT integrates all traffic management and switching functionality to be able to connect to a backplane directly. To manage the increase in bandwidth, the CS8120 OLT has advance traffic management implementing hierarchy schedulers, multi-level shaping, policing, rate limiting, and subscriber/service-based bandwidth management. The CS8120 OLT is compliant with the latest carrier specifications (for example, CTC v2.1). Unlike programmable FPGA solutions for prototyping, the CS8120 OLT is a production-worthy integrated ASIC device.
