BNMUX Integrates Entropic Communications' C.LINK Chipset in New FTTH Modems

Posted on: Tuesday, 31 January 2006, 15:07 CST

Broad Net Mux Corporation (BNMUX) of Japan has integrated Entropic Communications' c.LINK(TM) Network Access chipset in its new high speed cable modem for fiber-to-the-home (FTTH) service, the BCL-100 Receiver and BCL-110 Network Controller. These new modems are specifically designed for the delivery of high-speed Internet and entertainment to and around multiple dwelling units (MDUs).

The BCL-100 uses Entropic's c.LINK EN3030 Access chip and the BCL-110 uses the c.LINK EN3010 Access Network Controller. c.LINK was originally designed for whole-home networking of digital entertainment over coax (the LAN), but applications outside the home (WAN) have emerged that require the conversion of fiber-to-the-home (FTTH) content and sending it to multiple coax outlets in MDUs. Entropic has taken the same technology and with modifications to the PHY and MAC, have reapplied c.LINK to the transportation of bandwidth intensive video and multimedia, including high-definition, streams, from outside the home to an access point in the home. Entropic is the only chip vendor able to address the distribution of entertainment via the LAN and the WAN using existing coaxial cabling.

The BCL-110 Network Controller is the interface between the optical fiber network termination (ONT) and the coax infrastructure in the MDU. The BCL-100 Receiver is the client modem connected to the existing coaxial wiring within individual tenant units. The BCL-110 Network Controller receives data from the optical fiber ONT and passes it onto the coax network in the MDU, while the BCL-100 receives signals from the coaxial wiring within individual tenant units.

"Our c.LINK modem can deliver rich contents of FTTH service. Coax is the only delivery medium that is robust to delivery uninterrupted video and entertainment. Using the existing cabling means ease of installation and use by the consumer, and Entropic's chipset helps us do that," said BNMUX Executive, Mr. Miyamoto. Japan's largest MSO, Jupiter Telecommunications has been deploying BNMUX's modems in their 100Mbps high-speed data service.

One BCL-110 can connect as many as thirty-one different receivers, allowing MDUs such as apartments and condominiums to use existing coax wiring for delivery of high-speed, broadband access services.

c.LINK Network Access Chipset

Entropic's c.LINK(TM) Network Access chipset leverages existing coaxial cable, enabling an easy, cost effective system for service providers to bring high speed data and video networking services to residents within MDUs. There are no new wires or changes to the existing wiring. The technology enables reverse communication through coax splitters and allows selection of broadcast frequencies from 850 MHz to 1500 MHz, with cascading of multiple network controllers to expand unit coverage and coexist with cable, terrestrial and satellite signals.

The c.LINK Network Access chipset is comprised of the EN1010 Coax Network Interface, the EN3030 Access Client and the EN3010 Access Network Controller in a 3.3V/1.8V power supply with 3.3V I/O PCI interface. The EN3010, in combination with the EN1010, is used in devices at the building point-of-entry providing more than 100 Mbps of broadband data to up to 31 units from a single network controller.

The EN3030 is also used in combination with the EN1010 in customer premise equipment (CPEs), such as a gateway or router. SNMP support, rate adaptation, system upstream and downstream management and support of IEEE 802.1p priorities, are all standard. Network security consists of both hardware DES encryption and network coordinator access control nodes.
