One of the advantages of fiber optic technology is that it is bidirectional, with downstream capacity and upstream capacity being essentially the same. That's not the case for networks that rely on copper for the "last mile" such as cable and DSL. Now Mediacom is starting to clamp down on customers who are using too much upload capacity - even if they aren't hitting their data caps. According to an article at Ars Technica, Mediacom has contacted customers who use a lot of upload capacity and telling them to cut back or face consequences, citing its Acceptable Use Policy that allows it to enact penalties for excess usage that, in its opinion, impacts other users. Mediacom's top tier of internet advertises download speeds of up to 1 gigabit (Gbps) per second. That's 1,000 megabits per second (Mbps). Upload speeds for that tier are capped at 50 Mbps, or just 5% of downloads. The data cap for this tier is 6 gigabits per month.

Instead of "is bidirectional" a better term would be "can have symmetric bandwidth." Not all fiber technologies have symmetric bandwidth, for example GPON has 2.5 Gbps downstream and 1.25 Gbps upstream, which is asymmetric. For several years CFU configured service tiers to have the same ratio of downstream / upstream, such as 50 Mbps DS and 25 Mbps US, or 2:1. CFU moved to symmetric service tiers a few years ago even though GPON is asymmetric. That 2 to 1 ratio was far better than actual usage, which traditionally had been 10:1. That ratio has shifted over the years, we have seen more like 8:1 because of YouTube uploads and other crowd-sourced media contributions. Due to the pandemic that ratio may have tilted even farther. If your access equipment is assuming 10:1, that is a problem, but you don't really need 1:1 or symmetric bandwidth for the vast majority of customers. Some XGS-PON implementations are not symmetric, however the one CFU has chosen is, which has positioned CFU to better handle future shifts in how customers use Internet services.
