BroadLight introduced a broadband passive optical network (BPON) controller for central office (CO) equipment. The new device is based on BroadLight’s existing FPGA but adds features and functionality, including:
- Extended BPON (1.25 Gbps downstream and 622 Mbps upstream).
- Dynamic bandwidth allocation (DBA) which enables higher upstream bandwidth utilization.
- Enhanced Utopia interface (Utopia 2 or 3 in a bus mode) for higher performance, cost and footprint reduction in a multi port CO BPON line card.
The new controller also includes the following embedded functionalities: SERDES, BPON framing and media access, a TDMA controller, cell transmission, queue management, traffic security, privacy, and out-of-band management.
The BPON controller is currently sampling and will be priced at under $50 in volume quantities for the 622 Mbps downstream and 155 Mbps upstream configuration, and slightly more for the extended BPON 1.25 Gbps downstream and 622 Mbps upstream configuration. http://www.broadlight.com
