Optimum Approved Modems

Below you will find the Optimum approved modems list. There are several options for one to purchase their own modem for Optimum’s internet service.

Read the Cable Modem Buying Guide to help you choose a modem. Do not forget to purchase your modem accessories.

Internet providers have begun removing some DOCSIS 3.0 modems from their networks. To maximize the years of use from a modem, it is strongly recommended to purchase a DOCSIS 3.1 device (the latest standard).
