With more and more CableLabs member operators deploying or preparing to deploy ITU-T-based passive optical networking (PON) technologies such as XGS-PON, interoperability of equipment from different vendors is more important than ever. One well-known source for the lack of cross-vendor interoperability of XGS-PON equipment stems from differing implementations of the ONU Management Control Interface (OMCI) […]

There has been momentum in the broadband industry to provide fiber to the premises (FTTP) solutions as a part of an operator’s service portfolio. While optical technologies have long been a part of the cable network, FTTP is the chosen architecture for all-fiber access networks. For FTTP, the premises can be a subscriber’s home, a […]

All too often, people equate the word “cable” with “coax” (aka coaxial cable), the insulated copper cable that cable companies have historically used to connect devices around the world and deliver information and entertainment. “Cable,” however, isn’t just made of metal but also of glass: fiber-optic cable (aka fiber). The use of fiber in cable […]

In the broadband industry, network operators and vendors are continually working together to advance interoperability and streamline operations — but the puzzle pieces don’t always fall into place easily. Passive optical networks (PONs), for example, face the ongoing challenge of achieving interoperability without stifling innovation. PON standards are intentionally written to be flexible and to […]

In the world of passive optical networks (PON), achieving seamless interoperability has been a long-standing challenge, leaving operators trying to fit square pegs into round holes. This legacy is largely due to the intentional flexibility in PON standards, designed to foster innovation by avoiding overly prescriptive implementations. However, this flexibility often leaves too much room […]

Consistent with the strategy outlined in a recent blog, CableLabs has recently launched two new working groups related to fiber to the premises (FTTP). Information on one of the working groups — Optical Operations and Maintenance — can be found here. The subject is this blog is the provisioning and management of passive optical networking […]

Imagine you’re a network engineer trying to manage the capacity of your DOCSIS networks — and suddenly you’re tasked with learning a whole new set of additional tools, techniques and terminologies to manage a new type of access network: a passive optical network (PON). Now apply that complexity to the entire operations, the many involved […]

Optical communication — transmitting light waves through fiber optic cables — continues to be the foundation for providing high-speed broadband services to consumers. Whether the network solution is 100 percent fiber to the home or fiber is just an overwhelming majority, you’ll find fiber optics at the root of the solution. To acknowledge the foundational […]

The U.S. government is investing billions of dollars in broadband infrastructure. That funding will predominantly be used to deploy fiber-to-the-premises (FTTP) networks using passive optical network (PON) technology. Most U.S. broadband providers are focused on deploying a 10G variant of PON technology, and two types are widely available in the market today: 10G-EPON and XGS-PON. […]

Alongside the hustle and bustle in the cable industry to deploy DOCSIS® 4.0 technology, another 10G solution quietly plods along with pinpoint precision: fiber to the premises (FTTP). In FTTP, the premises can represent a home, business, campus, multiple-dwelling unit, etc. Despite what fiber overbuilders might want you to believe, the cable industry has always […]
