Overview of the ECOB
The ECOB (EPON Convergence and Optical Exchange Board) serves as a crucial component in EPON (Ethernet Passive Optical Network) infrastructure. It facilitates the convergence and exchange of signals, ensuring seamless communication between EPON ports and Ethernet networks.
Key Components:
- Exchange Module: Enables the aggregation of 16 EPON port signals for efficient data exchange.
- Interface Module: Converts EPON optical signals into Ethernet messages and vice versa, ensuring compatibility and interoperability.
- Control Module: Manages software loading, operational control, and overall system management functions for optimized performance.
- Power Supply Module: Provides reliable power supply to ensure the uninterrupted operation of all function modules.
In essence, the ECOB plays a vital role in enhancing network connectivity, enabling efficient data transmission, and ensuring the smooth operation of EPON networks.
Product Features and Applications of the ECOB
High Density:
- Incorporates 8 EPON ports per card, supporting a remarkable split ratio of up to 1:128.
EPON Functionality:
- Implements ONU power-saving management as defined in G.987.3 standards.
- Accommodates 1024 T-CONTs per PON port and 4096 GEM ports per PON port.
High TM Performance:
- Features H-QOS support for enhanced traffic management.
- Offers extensive queue and scheduler capabilities with 1024 queues and 356 schedulers per PON port.
- Utilizes color-sensitive RED and WRED discard algorithms for efficient resource allocation.
Clock / Time Functions:
- Capable of receiving 1PPS+TOD signals and transmitting them to the ONU via a PON channel.
These features highlight the ECOB’s capabilities in delivering high-density, efficient EPON functionality with superior traffic management performance and precise clock/time functions.
