Hi Colton, For what it sounds like you’re really looking for, a remote MAC-PHY (or pre remote MAC-PHY, ala mini CMTS) would probably be the good fit for your application. This is certainly not an endorsement, as we haven’t used any remote MAC-PHY devices today.
There are a couple players pouring money into products that haven’t really been mentioned yet... 1) Huawei - which initially brought a mini CMTS to market (D3.0, 16x4.) Some C-DOCSIS stuff, so may be feature poor but it doesn’t sound like you really need the boatload of features that are in a classic full-size CMTS anyway. Not sure what’s going on with their D3.1 remote MAC-PHY general availability is either. 2) Gainspeed - D3.0/D3.1 product (not sure about where the generally availability of their product lines are) but if you happen to be a Juniper customer, they partner with Gainspeed so it can be easy to get engaged with them.
