CARLSBAD, Calif. and PARIS -- France's Teamly Digital selected the MoCA 2.5 networking integrated circuits (ICs) developed by MaxLinear -- which develops radio frequency (RF), analog and mixed-signal integrated circuits for the connected home, wired and wireless infrastructure, as well as industrial and multimarket applications -- for its new FiberCableStream cable micro-node.
FiberCableStream addresses a key dilemma of every cable MSO, justifying the extremely high cost of last meter hybrid fiber-coaxial (HFC) network upgrades to enable fiber to the building (FTTB) or fiber to the home (FTTH), according to Teamly Digital.
These last meter network upgrades are extremely difficult to cost-justify as the expense of construction and installation is not distributed across hundreds or thousands of users but rather a single user or, best case low tens of customers, the vendor said. Designed specifically to deliver ultra-broadband services by using the existing HFC plant, FiberCableStream enables new multi-gigabit capacity while co-existing with legacy cable, satellite and terrestrial networks on the same coaxial cable.
FiberCableStream uses a micronode that combines a passive fiber optic architecture serving as the transition point from the passive optical network (PON) to the last meter coaxial network. Up to eight MxL371x MoCA 2.5 networking ICs are integrated into a FiberCableStream and serve individual client devices or coax network units (CNUs) that leverage MaxLinear MxL371x networking ICs to deliver multi-gigabit speed services to the individual subscriber.
The FiberCableStream micronode allows cable operators to leverage current DOCSIS technology while offering competitive high-speed data services as they transition to DOCSIS Full Duplex technology. These micronodes deliver power savings compared with alternative solutions, allowing them to be reverse powered over coax by the CNU installed at each customer premise, the vendor said.
FiberCableStream systems are designed to comply with DOCSIS provisioning, ensuring simple installation and maintenance very similar to existing DOCSIS solutions. Fiber-deep termination eliminates ingress funneling, laser clipping, CTB, CSO, CPD, micro reflections or any upstream RF network impairments. FiberCableStream is based on standardized technologies, including PON, MoCA 2.5, DOCSIS/CCAP and RF overlay.
"Cable operators will benefit from a cost competitive, flexible and operationally transparent gigabit broadband delivery system that can be deployed quickly over existing networks without any impact to legacy DOCSIS and QAM video services. Our implementation can be provisioned as a standard DOCSIS device and enables scalable, selective network upgrades," said Olivier Papy, general Manager and chief technology officer at Teamly Digital.
Added Vincent Pirson, senior vice president New Access Technology of Teamly Digital: "MaxLinear’s MoCA 2.5 technology is key to solving a crucial part of the challenge, which is getting gigabit bandwidth from the existing coax infrastructure."
MxL3710 and MxL3711 Technical Features
Both the MxL3710 and MxL3711 use MaxLinear's Full-Spectrum Capture (FSC) technology that can simultaneously digitize up to 1.4GHz of spectrum (between 400MHz and 1700MHz), eliminating discrete components required for frequency conversion. Each product includes fully digital channel selection and signal processing chain, as well as MoCA network processor and three-port, layer-two switch between its interfaces.
The MxL3710 features two SGMII high-speed interfaces while MxL3711 supports one SGMII and one PCIe. Both products exceed strict performance requirements defined by the MoCA 2.5 standard.
MaxLinear MoCA 2.5 ICs includes a suite of diagnostic software functions for visibility into RF and networking specific parameters. The spectrum analyzer feature, for example, enables installation and remote diagnostic tools, reducing truck rolls, improving installation quality and enhancing overall network performance with proactive network management tools.
The industry organization's major initiatives will address broadband differentiation based on quality of experience, global test labs for services, 5G, multi-access strategies and more, say CEO Robin Mersh and CMO Geoff Burke in an interview with BBWN.
After NTIA asked for public comments on map improvements in October 2018, the FCC decommissioned the agency's broadband map in early December but did not say whether it will use any of the public's great ideas on its own (largely panned) map.
Mike Zeto, GM of AT&T's Smart Cities division, expects metro areas to adopt platforms to manage multi-departmental IoT solutions once internal processes are aligned and more agencies are involved in smart city applications.
Consumers are buying millions of IoT devices, from smart thermostats and security systems to intelligent entertainment setups and furniture. Yet many of these devices remain isolated because home users are uncomfortable connecting them to each other – or even their WiFi. After all, their WiFi network was probably designed only to handle a few laptops, a gaming system and a couple of smartphones. Now, demand on the network is surging and even though you're delivering 100 Mbps to 1 Gbps, that doesn't necessarily mean the broadband power is in the right place or reaches every corner of a home.
Even if WiFi coverage is sufficient, typing is not on trend. Voice is far more natural, easier and faster. Using a TV keyboard is archaic when more and more households have access to cloud-based voice services, like Amazon Alexa. This webinar will explore how service providers can create a comfortable, truly smart home for consumers – simultaneously driving up margin and loyalty.
