Calix CAF Phase II Auction Resources


Connect America Fund (CAF) Phase II Auction Winners!

The CAF Phase II Auction represents a great opportunity for aggressive service providers to find new growth opportunities in serving broadband starved communities. By definition, the communities targeted by this program were either underserved or unserved – on the wrong side of the digital divide – and their incumbent service providers were either unable, or unwilling, to commit to bringing these communities up to minimum national standards.

The auction awarded $1.5B of support over 10 years to bring broadband service to unserved census blocks in price cap carrier territories.  Auction winners have plenty of work to do and Calix is here to help!

FCC requires 60% homes passed within 3 years. Calix can help.


Chances Are You’re Not New To Delivering Broadband To Unserved Communities. Neither Is Calix.

CAF Phase II award winners have unique technical and geographic challenges to meeting the needs of unserved census blocks.  Whether you’re a wireline telco, WISP, municipality or electric cooperative, Calix has vast experience helping Communications Service Providers (CSPs) deliver broadband to unserved and underserved communities across America.

Are you ready for FCC CAF Testing?

In July 2018, the FCC released DA 18-710 describing its new rules for CAF Testing. This educational webinar is targeted to any service provider that is a recipient of Connect America Fund (CAF) high-cost universal service support. This webinar provides a snapshot to what tests are needed, when the tests are needed, how many test locations are required, and a solution set that will meet the FCC requirement.

All Calix fiber access solutions are gigabit speed capable

A Customer Advisory Bulletin “Throughput of Calix GPON and Active Ethernet Access Systems” which uses RFC 2544 test procedures to characterize the data rates of Calix solutions at different frame sizes can be accessed here:    

Calix solutions have industry leading latency characteristics

Latency in a PON network is measured in the upstream and downstream direction.  As a point to multipoint technology, it is important to understand the different factors to planning for latency. Some of these variables include packet size, traffic type (TCP or UDP), traffic load, uplink capacity (1GE vs 10GE) and ONT types. 

Calix leverages industry standard testing based on RFC2544 to measure throughput and latency across various configurations for our GPON and 10G PON solutions.  Due to the asymmetric nature of GPON (2.5Gbps downstream / 1.25 Gbps upstream), we have observed increased latency in the upstream direction versus the downstream direction.  Factoring in consideration for variables previously mentioned, Calix solutions typically maintain a latency of ~26 microseconds in the downstream direction and 750 microseconds in the upstream direction while supporting 1 Gbps services in a typical PON with 64 subscribers.    

Calix measures MOS scores for all of its solutions

The average MOS score for Calix fiber solutions is 4.13. The average MOS score for Calix copper solutions is 4.15.
