ARRIS SURFboard SB8200 DOCSIS 3.1 Modem
The SB8200 is designed for multi‑gigabit internet plans, leveraging DOCSIS 3.1 to support speeds up to 2 Gbps. It features two 1 Gbps Ethernet ports for flexible wired connections and a compact, modern chassis with LED indicators for power, upstream, downstream, and online status.

This model is well‑suited for households planning to maximize future cable offerings while minimizing rental costs from Optimum or other providers, pending provider compatibility checks.
NETGEAR Nighthawk CAX30 Modem Router Combo
The CAX30 combines a DOCSIS 3.1 modem with a Wi‑Fi 6 router, offering broad coverage for large homes and many devices. It supports plans up to 2 Gbps and can handle up to several concurrent streams with dual‑band性能 up to AX2700. Four 1 Gbps Ethernet ports enable high‑speed wired connections for gaming consoles, PCs, and streaming devices, while a USB 3.0 port adds flexible sharing options. This is a router‑included option, simplifying setup for Optimum households seeking strong wireless performance and simple management.
Arris G18 Cable Modem Router Combo
The Arris G18 integrates DOCSIS 3.1 with Wi‑Fi 6, delivering strong performance for streaming, gaming, and multi‑device households. The modem portion handles high‑speed cable plans, while the built‑in router supports modern wireless standards for improved throughput and network efficiency. It is a single device designed for households that want a simplified setup with fewer components while maintaining reliability and broad compatibility with major cable providers.
NETGEAR Nighthawk CM1200 Modem
The CM1200 is a DOCSIS 3.1 modem known for compatibility with major providers and support for plans up to 2 Gbps. It includes four 1 Gbps Ethernet ports for reliable wired connections across home devices and can be paired with a separate router for enhanced wireless coverage. This option emphasizes flexibility and future‑proofing, making it suitable for tech‑savvy households that want robust wired performance with the option to upgrade Wi‑Fi separately.
Hitron CODA56 Multi‑Gigabit Modem
The Hitron CODA56 is a DOCSIS 3.1 modem with 2.5 Gbps Ethernet and a modem‑only design, requiring a separate router for wireless connectivity. It is certified for compatibility with major cable providers and supports high‑speed plans, including those approaching multi‑gigabit levels. This model suits users who already own a high‑quality router or want to build a custom network layout with mesh or multi‑router setups to optimize coverage.
Buying Guide: Key Purchase Considerations
- DOCSIS standard and speeds: DOCSIS 3.1 devices generally offer future‑proofing for gigabit plans and beyond; DOCSIS 3.0 models target slower plans but can be cost‑effective if your service remains below 1 Gbps.
- Router needs: Modem‑only units require an external router, while modem/router combos simplify setup but limit some customization options.
- Provider compatibility: Confirm Optimum compatibility and any required firmware or activation steps with your service plan. Some devices may be recommended or restricted by ISPs.
- Home layout and device count: For larger homes or many devices, prioritize models with higher Ethernet port counts or built‑in Wi‑Fi 6 for broader coverage and reliable throughput.
- Future expansion: If you anticipate faster speeds, choose a DOCSIS 3.1 device and consider a high‑performance router or mesh system to match evolving bandwidth needs.
- Security and updates: Look for devices from brands with ongoing firmware updates and security features to protect connected devices.
When selecting a modem for Optimum, align your choice with your current plan and any anticipated upgrades. If you prefer a simplified setup, a modem/router combo may be best; if you want maximum control over Wi‑Fi performance, a modem‑only device paired with a robust router or mesh system can deliver superior coverage and customization. Always verify activation requirements and ensure the hardware is on Optimum’s approved device list or compatible with your specific plan.
