Opulan introduces EOC and EPON chips

The EOC chips are designed to perform access control and real-time bandwidth assignments for up to 144 subscribers over existing coaxial cabling.

The system uses a baseband, non-modulation signalling technique.

Data is transmitted at the spectrum between 5Mhz and 65Mhz.

The design is intended to eliminate the expensive modulation mechanism adopted by other competing technologies, while transmitting data at 20Mbps to end subscribers.

Furthermore, Opulan's EPON chips are said to accommodate traffic from EOC at fibre nodes, sending aggregated traffic at 100Mbps to OLT at Telco's central offices or MSO's head-end distribution centres.

Opulan's EPON SOCs are TR156-compliant and can be used at remote DSLAM backhaul, EOC uplink in FTTC/B or in FTTH directly.

The solution consists of two chips for the EOC system, the CLT and the CNU and another two chips for the EPON, the OLT and the ONU.

Together, they form broadband access, as well as a two-way traffic and service-enabled turnkey solution for MSOs.

Dr Zheng Liu, chief executive officer of Opulan Technologies, said: 'Equipment based on our EOC ASSPs will enable MSOs to quickly provide two-way interactive data and DTV services to 150 million CATV subscribers in China, without making any change on the existing coaxial cabling system.' A live-demonstration system will be showcased at CCBN2009 in March at the China International Exhibition Center in Beijing (booth A2707).

Opulan is already working with a number of CATV equipment suppliers to begin field trials in China and is also working with Tier-1 telecom original equipment manufacturers for EPON systems.

Both EOC and EPON production is expected in the second half of 2009.
