7 Best Optimum Compatible Modem Reviews and Guide


Even when the market is crowded with options, finding the best optimum compatible modem might be difficult. You will not have to choose their monthly renting package if you have a decent optimal modem. Simply install the best compatible modem and enjoy the fastest download speed. However, in a market with so many options, choosing one that truly delivers on its promises can be difficult. So, conducting extensive research is required in order to have fantastic service with the best modem. When selecting the best ideal-suited mountains, we keep the three primary characteristics in mind.

Maximum Speed:

Different types are built to support a specific range of speeds. However, modems designed to provide the highest possible speed will undoubtedly be costly. Unless you intend to upgrade to the fastest Optimum services, you can select modems that offer speeds comparable to the internet plan. However, you should not get a modem with a lower maximum speed than their internet subscription. You will be unable to receive the service for which you have paid. So look into the plan you want and find out what the manufacturer’s maximum recommended speed is for maximum download speeds.

DOCSIS Technology:

DOCSIS, or data over cable service interface specification, is a standard for transmitting internet data over coaxial cables. Many cities employ DOCSIS 3.1; nevertheless, the majority of the best lines use 3.0. As a result, you must confirm the modem technology once more. If you are unsure whether your area is utilizing 3.1 or 3.0, contact customer support. To ensure uninterrupted data transmission, select a suitable and comparable DOCSIS technology.

Build and Design:

Now, when selecting the most optimal compatible modem, you must consider not only technology and internet speed but also the build and design of these items. Always search for modems with solid bases and well-proportioned vents. Heat dissipation necessitates the use of these vents. Plastic construction is a good choice since it reduces overheating. Furthermore, the inclusion of LEDs aids in understanding the network condition. Consider the design and construction for convenience.

While these are the top three most crucial characteristics to never overlook, there are plenty of other important items to consider. These characteristics will be discussed more in the “Buying Guide” section. But first, we’ll take a look at some of the top optimal compatible modems on the market. Remember to thoroughly research the specs before purchasing a compatible modem. Only by comprehending the requirements will you be able to make an informed decision.
So, without further ado, let’s look at the best compatible modems.

ARRIS SURFboard SB8200 Cable Modem

The Arris Surfboard SB8200 is an excellent choice for any Optimum client wishing to upgrade their modem.

First and foremost, the SB8200 is compatible with any Optimum cable internet service.

This is owing to the fact that it is DOCSIS 3.1 with a maximum speed of 2000 Mbps.
This is also what makes it long-lasting.

Because you won’t need to buy a new modem when Optimum improves your internet to DOCSIS 3.1.

Furthermore, because DOCSIS 3.1 is backward compatible, it will operate with DOCSIS 3.0.
Ethernet aggregation is also available on the SB8200.

This enables you to merge two Ethernet ports into a single one with a maximum speed of roughly 2000 Mbps rather than 1000 Mbps.

This isn’t particularly useful right now.
Because Optimum does not provide any plans that exceed 1000 Mbps.

However, it is very likely that it will be in the future.

However, if you anticipate switching to fiber in the near future, I do not recommend the SB8200.

Because the modem is a long-term investment.
Assume you’ll get Fiber in a year or so.

In such a scenario, purchase a modem that meets the minimal criteria for your current internet subscription (see table later in the article).

Overall, the Arris Surfboard SB8200 is a modem that you can buy and then forget about.

Because it is a value package that will last for years.


  • Future-proof
  • Works for plans up to 2000 Mbps
  • 2-year warranty


  • Ethernet aggregation is a bit hard to use

Netgear CM500 Optimum Compatible Modem

The Netgear CM500 is an excellent choice for anyone on the Optimum 300 Mbps plan or lower who wants to save money.

This modem is frequently mentioned in online evaluations, and for good reason.

It’s a good value package that will suffice for most people’s internet needs.

However, when ISPs like Optimum migrate to DOCSIS 3.1, it’s unclear how long this modem will suffice.

As a result, if you purchase this modem, you should be aware that you may need to replace it sooner than intended.

However, if you have a slower internet connection and are on a tight budget, it is a viable option.


  • Cheaper


  • Not future-proof
  • Slow

Netgear CAX80 Optimum Compatible Modem

The Netgear CAX80 is one of the fastest modem/router combinations I’ve tested and is compatible with any internet plan up to Optimum 1000.

Unfortunately, I was unable to test its maximum speed during testing because the internet plan I had access to only reached 800 Mbps.

However, it did attain 800+ Mbps from a distance of 5 feet and 583.15 Mbps from a distance of 25 feet.
Both use the 5GHz frequency band.

These are some of the best results I’ve ever gotten with a modem/router combination.

And will be plenty for a family of 7 or more to utilize the internet without difficulty.

The main disadvantage of the CAX80 is the same as that of the C7800: it lacks functionalities.

Because it lacks Parental Controls and QoS, which allow you to limit your child’s internet activities and priorities network applications.

These are the characteristics I would anticipate from a modem/router combo at this price.

Furthermore, the CAX80 is a little pricey for anyone who isn’t on the Optimum 500 Mbps plan.

Overall, the Netgear CAX80 is ideal for those looking for a modem/router combo and a high-speed internet connection.


  • Future-proof
  • Extremely fast
  • Good range


  • Lacks features (such as QoS and Parental Controls)
  • Pricey

It’s also DOCSIS 3.1 compatible, so it’ll work with any Optimum internet subscription.

The TM3402 has the disadvantage of being difficult to get.

It is in high demand because it is one of the few voice modems compatible with Optimum that isn’t ancient and slow.

Buying Guide for the Best optimum Compatible Modem

It will be easy for you to make your own pick from all of the names of the greatest optimal compatible cable modems accessible on the market. If you have already decided to purchase one that is not on the list, you must review the specifications and features.

Aside from that, you must understand how the requirements will benefit you. So, in this buying guide, we’ll look at some of the key qualities that must be present in a cable modem to ensure optimal speed and latency reduction. Check all of these criteria before making a decision to experience the best performance.

Maximum Speed

The first and most important feature that any manufacturer will say is the maximum speed that the modem can give. You must select an internet speed that will fulfill your needs based on your requirements. While there are numerous internet service providers offering various plans, you can choose any one based on your needs.

However, when selecting a package, you must also ensure that you get a modem capable of providing the same internet speed as your service provider. Only when the internet service provider and modem are both at the same speed can you enjoy fantastic speeds.

DOCSIS Technology

Every cable modem mentions DOCSIS as a technology. It is a standard for transmitting internet data through coaxial cables. Many cities are served by 3.1, while other Optimum cable networks are served by 3.0. So, depending on your region, you must select DOCSIS technology.

However, if you choose 3.1 technology, you can be confident that it will operate with DOCSIS 3.0. However, it is best to consider your local requirements when selecting technology. Because 3.1 is the most recent technology with an updated feature, it may be more expensive.

Design and Built

The second item you should look at is the modem’s design and construction. By design, we mean that you should inspect the number of vents in the modem. More airflow means less heat buildup and better heat dissipation. This will have less of an impact on your modem’s speed range. Aside from that, you should look into the material used in its construction, as this will affect its durability.

Ethernet Ports

Ethernet ports are required when using an internet service provider. Check the amount of Ethernet ports when shopping for the best compatible cable modem. Check the speed range listed in the Ethernet ports as well to ensure that you are choosing a compatible decision with your internet service provider. With extra Ethernet ports, you will be able to use multiple Ethernet cables for different purposes at the same time.


Last but not least, the modem’s compatibility. When selecting the most compatible modem, make sure it is compatible with different internet service providers. You can go to the manufacturer’s information to find out which providers the gadget is compatible with. You may quickly select the modem for the best experience if you use services from the list of compatible providers.

Rent Vs. Buy Devices From Optimum

Renting a modem from Optimum costs between $10.00 and $20.00 per month.

This cost amounts to approximately $120-$240 per year. This is sufficient to purchase a high-quality modem every year.

As a result, I propose that most individuals purchase a third-party modem. Because it is simply less expensive in the long term.

Nonetheless, there are certain advantages to renting. If you’re going to transition to fiber soon, it can be cheaper to rent for a few months rather than buy.

Because fiber optic internet does not rely on cable modems. However, for most people, buying will be far less expensive in the long term.


Can I buy my own modem for Optimum?

You certainly can. In fact, purchasing an Optimum-compatible modem is significantly less expensive than renting one. You will save roughly 120 USD on average within the first year of your purchase, which is the cost of a quality modem. So, without a doubt, I would advise you to purchase one.

What modems are compatible with Optimum Online?

This article contains the answer to this question. I finally came up with a list of the five best options after testing dozens of modems with Optimum ISP. They are not only ISP-compatible but also offer superb wireless connectivity at an affordable price.

Do I need any additional ports if I do not have a PC?

If you don’t already have a gaming console or a PC, I recommend purchasing a modem with at least two Ethernet connections because you never know what the future holds. As a result, it is prudent to purchase a product that is future-proof.


Because I’ve previously eliminated numerous terrible alternatives, all of the Optimum compatible modems mentioned here are suitable. Feel free to select any of them; they will all do the job.

If you’re still undecided, here’s what I’d choose depending on a different budget, service package, and special requirements:

Nothing matches the Arris Surfboard SB8200 for the best overall modem with the latest features like DOCSIS 3.1. You may use it with any Optimum service package, including the Gig Internet plan, and it should function perfectly.

If you prefer a simple modem/router combo to a strong stand-alone modem, the Motorola MG8702 is a solid option. My experiments show that it works best with the Gig internet plan.

If you’re a student or a professional who doesn’t indulge in data-intensive activities, the affordable Netgear CM700 is a great buy for you. It can be paired with the 300Mbps internet plan and should give you consistent speeds without any issues.
