Anyone remember the jingle for Jolt® Cola? All the sugar and twice the caffeine! Perhaps the phrase dates me, but I still hear it in my head—although I now have new words to set to it: All the distance and twice the capacity! OK, maybe it doesn’t have quite the same ring to it. But […]

This past June, CableLabs publicly released the first issued version of the Coherent Termination Device (CTD) Requirements Specification. The same month, the Institute of Electrical and Electronics Engineers (IEEE) Standards Association (SA) approved amendment 802.3ct-2021, which defines 100G Ethernet using coherent optics. Combined with previous point-to-point (P2P) coherent optics specifications released by CableLabs, these two […]

CableLabs is pleased to announce that, for the first time, a DOCSIS® 3.1 specification–compliant cable modem that includes the Low Latency DOCSIS (LLD) set of features has become CableLabs Certified. This announcement represents a major milestone on the path toward 10G because LLD support is key to improving latency on DOCSIS networks, and improving latency […]

Light Reading recently posted an article titled “Operators need to prepare for the game-streaming tsunami” which talks about a new wave of game streaming services (aka cloud gaming services) that are on the way. The article points out that the network demands these services require are completely different from anything cable operators have had to […]

Those of you who’ve heard me speak on the topic of Point-to-Point (P2P) Coherent Optics have probably noticed that I’ve placed this technology in the context of the cable industry’s move to Distributed Access Architectures, and as a result, the dramatic change in the way networks are architected. It’s a change that I would argue […]

Not every time can be the first time:  there can only be one first interop, or first spec release, or first technology demo. Saying you’ve done something for the second time doesn’t carry the same excitement or cachet as saying you did it for the first. And yet, the first time at anything is rarely […]

0.0000026 seconds. For the more technically inclined, that’s 2.6 microseconds. Which is how long it would take light to travel a third of a mile through fiber optic cable. It was also the length of the show floor at OFC: The Optical Networking and Communications Conference and Exhibition, held in March in San Diego, California. […]

Today, CableLabs is announcing another addition to our family of Point-to-Point Coherent Optics specifications:  The Physical Layer 2.0 (PHYv2.0) specification. This new specification defines interoperable point-to-point (P2P) coherent optics links running at 200 Gbps (200G) on a single wavelength. Just 9 months ago, in July of 2018, CableLabs announced the release of the P2P Coherent […]
