In another annoucement to coincide with the Fibre to the Home conference in the United States, Calix has released its latest access innovation, a first to market Extended Reach GPON technology based on ITU-T standards.

New amendments to the GPON standards enable service providers to dramatically increase their serving areas when deploying GPON FibertothePremises (FTTP) technology. The Calix Extended Reach GPON solution delivers this new functionality as a pluggable optical interface module (OIM) inserted into the existing optical line terminal (OLT) line cards on the Calix C7 Multiservice Access Platform (MSAP). The solution is supported by all Calix 700, 700G, and 700GX optical network terminals (ONT), the industry's broadest portfolio of residential, business, and multidwellingunit ONTs, including those already deployed in the field.

While it might be new and a first to market for a GPON vendor, like the recent Alcatel annoucements this functionality has been available for some years in the GePON space. Alloptic has been delivering extended reach GePON ONTs for a number of years with a range of up to 70kms, abet at a lower spit ratio.
