EC8B 8 ports description:
Exchange module to achieve the convergence of EC8B 8 ports signals. Interface module to realize the mutual conversion between EPON optical signal and Ethernet message.
The clock module provides a working clock for each function module in a single board. The power supply module provides a working power supply for each function module in a single board.
Feature and application of the EC8B 8 ports:
High TM Performance:
– Support H-QOS
– 1024 queues and 356 schedulers per PON port
– Support color-sensitive RED and WRED discard algorithm
Clock / Time Function:
– Receive 1PPS+TOD signals and send them to the ONU through a PON channel
Low Power Consumption:
– Newly developed lower power EPON MAC chip
– Reduce 30% power consumption on industry average
High Density:
– 8 EPON ports per card, up to 1:128 split ratio
* EPON Function:
– Support ONU power saving management defined in G.987.3
– 1024 T-CONTs per PON port, 4096 GEM ports per PON port
