Buying Guide for the Best Optimum Online Compatible Modems

Choosing the right modem for your Optimum Online service is crucial for ensuring a stable and fast internet connection. The modem you select should be compatible with Optimum's network and meet your internet usage needs. Here are some key specifications to consider when picking the best modem for you.
CompatibilityCompatibility refers to whether the modem can work with Optimum Online's network. This is important because not all modems are designed to work with every internet service provider. To ensure compatibility, check Optimum's list of approved modems. If a modem is on this list, it means it has been tested and certified to work with their service.
DOCSIS StandardDOCSIS (Data Over Cable Service Interface Specification) is a standard used to transfer data over cable TV systems. The most common standards are DOCSIS 3.0 and DOCSIS 3.1. DOCSIS 3.0 is sufficient for most users and supports speeds up to 1 Gbps, while DOCSIS 3.1 is newer and supports speeds up to 10 Gbps. If you have a high-speed internet plan or want to future-proof your setup, go for DOCSIS 3.1. Otherwise, DOCSIS 3.0 should be adequate.
Channel BondingChannel bonding refers to the number of downstream and upstream channels a modem can use simultaneously. More channels can mean better performance and higher speeds. For example, a 16x4 modem has 16 downstream and 4 upstream channels. For basic internet usage, a 16x4 modem is usually sufficient. For heavy internet usage, such as streaming in 4K or online gaming, consider a 24x8 or 32x8 modem.
SpeedThe speed of a modem is the maximum rate at which it can transfer data. This is important because it determines how fast your internet connection can be. Match the modem's speed capabilities with your internet plan. If you have a 200 Mbps plan, a modem that supports up to 300 Mbps will be sufficient. If you have a gigabit plan, you'll need a modem that supports higher speeds, like 1 Gbps or more.
Ethernet PortsEthernet ports are used to connect your modem to other devices, such as a router or computer. The number of ports can vary, but most modems have at least one. If you plan to connect multiple devices directly to the modem, look for one with multiple Ethernet ports. For most users, one or two ports are sufficient, especially if you use a separate router.
Built-in RouterSome modems come with a built-in router, which can be convenient as it combines two devices into one. This is important if you want to save space and reduce the number of devices you need to manage. However, built-in routers may not offer the same performance or features as standalone routers. If you have specific needs, such as advanced security features or better Wi-Fi coverage, you might prefer a separate modem and router.
ISP SupportISP support refers to the level of customer service and technical support you can expect from your internet service provider when using a particular modem. This is important because if you encounter issues, you want to ensure that your ISP can help you troubleshoot. Using a modem from the approved list ensures that Optimum Online will provide support if needed.
