5 Best Optimum Compatible Modems in 2023 [Compatibility Confirmed]

The official Optimum certified modem list includes underpowered bad modems. And the worst part is, you can’t actually find a list of devices supported by them. However, to experience higher speeds and throughput, you need a highly efficient modem compatible with Optimum. Here are my top 5 picks for 2023:

• Best For Optimum 1 Gig: Arris SB8200
• Best For Gaming & Streaming: Netgear CM1100
• Best Modem-Router Combo: Motorola MG8702
• Best For 500 Mbps: Netgear CM700
• Best For 300 Mbps: Arris SB6190

While getting a cable modem for Optimum, it is advisable to align your requirements beforehand and pick the device based on your needs and budget.

Many of my readers have contacted me that they went through some unverified lists and ended up getting a modem that doesn’t work with Optimum. To confirm that my list actually includes devices that work, I’m adding a screenshot of my conversation with Optimum chat support.

As for the features, it should feature the latest DOCSIS technology i.e DOCSIS 3.1 or 3.0 (as DOCSIS 4.0 modems are not out yet), higher speed limits, and stability. Also, it should suit the internet plan you’ve subscribed to. There’s no point in buying a gigabit modem if you’ve subscribed to an Optimum 300 or vice versa.

5 Best Optimum Compatible Modems in 2023

The market is flooded with many options, yet finding the best modem for Optimum can be a stretch if you do not know where to look. In the following discussion, I shall review the top 5 Optimum-approved modems to use in 2023.

I would also like to add that each device has been tested thoroughly for at least 4 weeks across speeds, throughput, consistency, usability, and other parameters. That said, I’ve tried to cover models that serve different purposes. Let’s go!

1. Best Optimum 1 Gig Modem: Arris Surfboard SB8200

Arris SB8200 is the best all-around modem for Optimum 1 Gig Internet. Read on to know how it secured the 1st position on my list.

If you’d like to invest in a reliable, reliable, top-of-the-line modem that works without frequent restarts and lasts longer than usual, I recommend the Arris SB8200. While the future-proof DOCSIS tech makes it a standout performer, it fits right into the list due to its aesthetic layout.

And if you compare SB8200 with the older SB6190, you would love to know how faster (200 Mbps at least) and, more importantly, consistent it is.

Why is it suited for Optimum?

What gets this modem in is the DOCSIS 3.1 networking technology — a feature that renders the device future-proof. In case Optimum comes with multi-gig internet plans, you can rely on this modem to get the job done, courtesy of the 2 x 2 OFDM/OFDMA channels that also stand for additional transmission width.

Despite being a DOCSIS 3.1 modem, the SB8200 is more than capable of working with DOCSIS 3.0 devices, known as backward compatible in networking terms. And while the DOCSIS 3.1 is relatively futuristic, the 32 x 8 channel bonding makes the SB8200 good enough for a high-speed 1Gig internet connection from Optimum. 

There are 2 Gig ethernet ports in play, allowing you to connect the modem to at least two bandwidth-intensive devices directly. I tested the device with Optimum’s 1Gig plan, only to see it reach max wired download speeds of up to 900Mbps, and upload speeds of 60Mbps. The mentioned speed thresholds are good enough for high-speed gaming and 4K streaming.

Design & Build

Trust me, if you are in it for the aesthetics, the SB8200 won’t disappoint. It assumes a vertical layout primed in black and features four LEDs for a better status indication. The side-adhering heat vents work well, allowing standard heat dissipation. Made of plastic, the device weighs close to 2 pounds and measures 5 x 2 x 5 inches, to be exact.

Hardware & Other Features

The SB8200 has a competent processing setup, led by a multi-core ARM-powered chipset and 512MB of RAM. This arrangement allows the device to cut through any form of congestion. Link aggregation is missing, though. Still, Arris makes up for the same by including OAM support for better diagnostics and a full spectrum bandwidth tuner for better network prioritization.

Conclusion

Finally, if you are looking for a reliable Optimum 1 Gig modem, the Arris SB8200 is the one you should pick, owing to its advanced DOCSIS setup. Also, if you compare it with every other product on the list, Ethernet ports’ processing setup and quality stand out.

2. Best for Gaming & Streaming: Netgear CM1100

Need a modem that doesn’t heat up while gaming or streaming? Here it is!

There aren’t many good-looking standard modems that support Optimum. Well, that changes today with the Netgear CM1100 in play, as it comes as a market leader in terms of the well-ventilated design. And guess what, it is an excellent upgrade to the older CM1000, owing to the better DOCSIS technology that focuses on the future.

Why is it suited for Optimum?

The DOCSIS 3.1 technology makes it special, allowing you to take advantage of the 32 x 8 channel bonding support (associated initially with DOCSIS 3.0). And just so you know, the channel bonding support allows you to get the best possible speeds even during peak hours. The device is backward compatible and can even work with the legacy DOCSIS 2.0 products that you might have around.

There are 2 ethernet ports, allowing you to reach 1Gbps speed on each. What makes it worthwhile is that you can deploy the link aggregation (provided two IPs are assigned) to achieve multi-gig speeds over each port. And that makes it an excellent choice for connecting to 4K streaming and gaming consoles.

Anything less than Optimum 1Gig wouldn’t justify the price you’d shell out for this Optimum internet modem. Also, the practical download and upload speeds of 850Mbps and 55Mbps make a compelling case for data-intensive needs.

And as seen in my review of the Netgear CM1100, it doesn’t lag or throttle while gaming or streaming.

Design & Build

The CM1100 is one of the better-looking devices, boasting a plastic-clad chassis in grey, a 10-LED rose gold stripe in the front, a robust base stand, and a vertical layout. The heat-dissipating vents on the sides are pronounced enough to keep the device cool and throttle-free. The device feels sleek as it measures 8.8 x 3.4 x 5.9 inches and weighs 1-pound.

Hardware & Other Features

There is a multi-core chipset at the helm, coupled with 256MB of RAM, making it easier for the device to cut through any interference. The 128MB flash memory is worth the splurge, allowing you to store the firmware details without breaking a sweat.

On top of that, it offers several user-ready features like IPv6 support for better configuration, OFDM/OFDMA support for future-proofing the modem-specific offerings, and not to forget easy installation.

Conclusion

If you want to replace the Optimum modem with your own, Netgear CM1100 is arguably one of the best options. And this product makes perfect sense to someone whose work may heat up the device. And if you want to compare it with other products, consider the ultra-fast processing setup and congestion-cutting abilities to take center stage.

Yes, I love modem-router combos, especially ones that work with high-speed plans. The Motorola MG8702 is one such device with a USB port and app support that make management more effortless. And if you have been eying the older Motorola MG7700, the MG8702 is a better bet, owing to the better networking technology, which is both futuristic and faster.

Why is it suited for Optimum?

The DOCSIS 3.1 technology takes center stage, owing to the ultra-fast data transmission speeds. There are 32 x 8 channels, enabling much usable bandwidth for multiple devices. This DOCSIS 3.1 modem for Optimum is duly backward compatible and works with DOCSIS 3.0 and legacy devices.

As it is also a wireless router compatible with Optimum, 4 Gig ethernet ports are in action. Using each, you can connect to dependable, smart devices. And while Motorola doesn’t declare link aggregation support, each port can help you reach max data speeds of 950Mbps and 70Mbps (download and upload) over a wired connection. This means it is more than enough for streaming, gaming, and conferencing.

I tested the MG8702 with Optimum’s 1Gig plan, only to find it achieves wireless speeds of 700Mbps and 45Mbps, respectively, over the 5GHz band. For the far band, 100Mbps and 15Mbps speed limits were reached, which is more than acceptable. Adding to the same is the overall LAN wireless throughput of up to 3.7Gbps, independent of the internet plan you seek.

Design & Build

The MG8702 comes in grey, has the right alignment of heat-dissipating vents (just like the Netgear model) to keep the device cool, features a steady base, and makes room for 9 indicative front-facing LEDs and 8 rear-facing LEDs for reporting the status. The combo feels slightly beefy at 9.5 x 2.8 x 9.75 inches and 2.15 pounds.

And to make things more exciting and support LAN-based media transfers, there is a standard USB 3.0 port, sitting pretty with the Ethernet ports.

Hardware & Other Features

Optimum Approved Modems [Official List]

A Beginner’s Guide To Buying a Modem

After you have gone through the Optimum compatible modem list, selecting one might not get any easier. Right now, you should be hitting the drawing board and getting a feel of the preferences, features, and other factors that might affect your choice.

Optimum Internet Plans

Plans	Max Download Speed	Max Upload Speed	Price
Optimum 300	Up to 300 Mbps	Up to 35 Mbps	$40/mo
Optimum 500	Up to 500 Mbps	Up to 35 Mbps	$60/mo
Optimum 1 Gig	Up to 940 Mbps	Up to 50 Mbps	$80/mo

Keeping the plans restricted to cable internet connections, you can opt for Optimum 300 as a standard gaming and internet pack or the 1 Gig internet plan for office connections.

Your Requirements

It all comes down to the why. Like why do you even need the modem for Optimum in the first place? For instance, a powerhouse is preferred if you plan to set up a multi-device home or office setup. Something that lets you reach multi-gig speeds, with more than one Gig port and link aggregation support. Remember the CM1100 from Netgear?

Yet, if you are a value buyer who wouldn’t want to spend time shopping for a new router, a combo like the MG8702 might be a better option. And while you are at it, you might want to weigh your voice-over-IP requirements or bundled TV plan requirements, if any. And depending on the choice, you might want to pick a suitable modem.

Speeds & Channel Bonding

Regarding the speeds, you might want to choose the right internet plan and then look for the Optimum online modem. If you are a typical gamer with a few devices at home, the Internet 300 plan might make sense.

However, if you have multiple devices at home and prefer the best-in-class Gig internet plan with 940Mbps as the peak offering, your choice of Optimum internet modem might need to get a bit more premium. Depending on the speed needs, you can either go for a DOCSIS 3.0 or a DOCSIS 3.1 modem. (Check the differences)

You can even double down on the port arrangement here. If there aren’t many bandwidth-intensive devices at home and you do not want to connect to a WiFi router, as yet, one Gig ethernet port might be enough. If you stick to a combo, there might be more than two ports in play, making it easier for you to set up high-gain wired connections.

For gaming and streaming, anything adobe 200Mbps works, and therefore, every Optimum connection might be good enough.

Hardware & Design

You might not give much thought to a modem’s processing setup but trust me, it surely plays an important role. First, a multi-core processor followed by 256MB of RAM is a must, as only then will you be able to wade through interference and congestion.

Also, the design matters because you would not want the device too bulky. It is advisable to pick something light, comes with functional heat vents, has a steady base or stand for stability, and is loaded with at least four LEDs to indicate any network status or glitch beforehand.
