XGS-PON

Our final Interop·Labs event of 2025 was held last month at CableLabs headquarters in Louisville, Colorado. As with prior events, the week focused on interoperability aspects of the ONU Management and Control Interface (OMCI), defined via a combination of ITU-T Recommendation G.988 and the CableLabs Cable OpenOMCI specification. This event continued our approach of pairing […]

The latest CableLabs Interop·Labs CPMP XGS-PON event took place Aug. 4–7 in our Louisville, Colorado, labs and was designed to test the ONU Management and Control Interface (OMCI). The event focused on exercising a core subset of the OMCI requirements defined by a combination of the ITU-T Recommendation G.988 and CableLabs’ Cable OpenOMCI specifications. For […]

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 […]

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 […]

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. […]
