5 Best Fiber Optic Modems in 2023 [WiFi Gateways]

Fiber Optic connections don’t require a modem. They work with ONT (Optical Network Terminal). Internet providers usually provide the ONT device during installation, and all you need is a high-speed router that can handle fiber internet.

However, if you don’t want to invest in a high-end router, you can opt for a fiber modem/router, which is an easy-to-use gateway. Keep in mind that it won’t be as powerful as a traditional router. Anyway, which one should you choose?

Well, finding the right device can be challenging due to limited options, technical jargon, and ISP compatibility issues. To help with this, I tested 9 gateways that support fiber internet and finalized my top 5 picks.

5 Best Fiber Optic Modem/Routers of 2023 [WiFi Gateways]

An ideal fiber modem includes multiple networking modes, good speeds, a handful of Ethernet slots, and capable hardware. Considering these factors, this list is handpicked to suit diverse user requirements and internet providers.

1. Best Overall: Verizon FiOS CR1000A

Making its place at the top, Verizon FiOS CR1000A is one of the best gateways available. It brings WiFi 6E and Tri-Band frequency – a solid combination for high-speed internet. The high-end antennas, alongside two 10G and two 2.5 Ethernet ports, each to support top-tier performance. But it’s only compatible with Verizon FiOS.

Besides, compared to its predecessor, it brings multiple upgrades, and many were a surprise for me.

Speeds & Performance

The CR1000A brings the new 6 GHz band and tri-band setup in routing. Although its theoretical throughput cap isn’t revealed yet, it’s said to support Gigabit+ speeds. This is why I got the Verizon 1 Gbps plan to test it out, and here are the results:

To start with, I placed my test device, or Dell XPS laptop, stationed 20 feet away from the gateway and managed speeds of up to 861 Mbps and 664 Mbps, respectively, for downloads and uploads.

Meanwhile, 40 feet away, I got respective speeds of up to 427 Mbps and 265 Mbps.

The speed drops were a bit concerning, but I could stream any movies, videos, or other content in 4K and attend HD Zoom video calls without a bit faltering in quality. 

WiFi Coverage & Devices Capacity

The FiOS CR1000A, with its highly amplified antennas, claims to cover up a space of up to 2,000 Sq Ft, which is great compared to other fiber-optic gateways available.

To put its penetration ability to a test, I installed it at my grandpa’s 100-year-old house with thick walls. And it managed to encase the entire 1,500 Sq Ft space with signals.

The antennas further work in tandem with MU-MIMO tech to handle up to 30 devices, and the numbers maxed out at 24 in my test. These are inclusive of my bandwidth-hogging devices like laptops, computers, smartphones, and others.

Ports & Design

You’ll find two 10G LAN/WANs and two 2.5 LANs alongside a MoCA 2.5G port to support multi-gig plans. I got a 2 Gbps plan, established a wired connection with the 10G port, and got a maximum download speed of 1.96 Gbps and upload speed of 1.74 Gbps.

Besides, the best part is the gaming performance it delivers, as I could play Overwatch at a faster 5ms ping and 103 FPS with video streams running in the background.

Verizon upgraded the design from G3100, as you see a clean rectangular build with dimensions of 10 x 6 x 6 inches. Less footprint means your desk has space to accommodate other things.

Hardware

The manufacturer hasn’t revealed much about its processing setup but telling by the performance, it’s indeed beastly. The processor with 2GB RAM and 4GB flash memory never stops you from installing firmware or compromising your gaming performance.

The latency is appropriately low, courtesy of the interference-immune hardware.

Conclusion

Verizon FiOS CR1000A has everything one expects from a high-end fiber-supported modem. Its speeds are impressive, it can cover a lot of space with signals, and its multi-gig ports are there for your high-end gaming or streaming connections. But its premium cost is what makes it untouchable for many users.

2. Best Runner-Up: Verizon FiOS G3100

The G3100 is yet another fiber gateway from Verizon FiOS. It brings the Wi-Fi 6 and Tri-Band for a fast and reliable wireless connection. Next is FTTP technology, allowing you to maximize internet speeds without losing packets.

The G3100 entails a tri-band Wi-Fi 6 setup for you to pair up speeds over 1 Gbps. I got the FiOS 1 Gbps plan and my MacBook Pro 16″ to record speeds at various distances.

The gateway clocked download speeds of 709 Mbps and upload speeds of 554 Mbps at 20 feet.

Farther away at 40 feet, the speeds are still very good, measuring 378 Mbps and 271 Mbps, respectively, for downloads and uploads.

The speeds, however, are a bit lower than my previous pick, but the performance it delivers ensures you and your family have no issues playing online games, streaming 4K content, and doing some heavy browsing.

WiFi Coverage & Devices Capacity

A big part of any router or gateway’s performance is its range, which measures how a connection is affected by distance or objects. With a stipulated range of 2,000 Sq Ft, the G3100 stays just identical to my top recommendation, which is good. The maximum distance I could access the signal was around 1,500-1,600 Sq Ft.

But, it disappoints a tad when it comes to the connection handling capacity. Despite entailing MU-MIMO, the gateway only allows 20-30 devices to connect at a time. That’s still decent for any family of four to five people residing in a mid-sized house.

Ports & Design

The G3100 is replete with 4 Gig LAN to connect to more bandwidth-intensive devices like gaming consoles, smart TVs, and more. And there is a standard WAN port. Next is the MoCA cable, allowing you to make the most of the multimedia plans.

As far as design is concerned, G3100 is a good-looking, dome-shaped device with white-colored, hardened plastic. Not to mention the solitary LED indicator in the front, followed by a heat-dissipating matter panel. The rear panel is all about the ports.

Hardware Setup

A multi-core processor is at the helm, supported by 512 MB of RAM. The featured chipset adds a lot to the performance of this fiber internet modem router, especially when it comes to streaming.

Conclusion

The FiOS G3100 is one of the go-to devices for Verizon FiOS. If you want to prioritize speed, coverage, and throughput over anything else. For more specific details, check out the full review of the gateway model G3100.

Things To Consider When Getting Fiber Internet Equipment

Now that you know which fiber optic modem or gateway to pick, here is a detailed guide to analyzing the attributes better:

Understand Your Requirements

The first question that comes to mind while picking a fiber-ready modem setup is the need for it. For instance, are you planning to pick one for your standard home use or for intensive loads like gaming?

Or, are you looking to get one for the office or to establish a network in any commercial space? Depending on user requirements, you purchase the networking device.

Like if you want something for your small home, the Arris NVG468MQ might be a good bet. However, the C4000XG from Greenwave is one of the top modems for gamers, courtesy of the QoS support.

Compatibility with your ISP

ISP compatibility is the most important aspect to look at before spending your hard-earned money on modems that work with fiber connections.

Most gateway devices aren’t compatible with every ISP in the market. For instance, the powerful C4000XG works with CenturyLink, whereas the Arris NVG468MQ complements Frontier and Verizon FiOS.

Therefore, before investing, check out the ISP compatibility and pick only the one that makes sense to the area-specific service provider. And it is always better to pick one that covers most of the ISPs so you can move around and the device stays relevant.

Relevant Ports & Connectivity

If you have multiple bandwidth-hungry devices at home or office, including the Smart TV, PS4 or PS5, and more, I would recommend considering a device like the C4000XG, which offers multiple Ethernet ports, 5 to be exact.

However, if you want to pair an extender to the modem-router combo or standardize the usage, it is better to go for a device with one to two ports. That way, you can save some money as well.

Hardware & Design

A multi-core processor is a nice addition to any networking setup. Yet, you must keep your eyes open for at least 256MB of RAM. Networking devices as powerful as those used for large offices might even have a multi-core processor with 512MB of RAM.

Next, you have the design, which might be an important parameter to consider while investing in a new fiber-supported modem. If you often change your workplace, it is advisable to get something light.

However, if you plan on keeping the device fixed at home or office, you might need to prioritize heat dissipation and durable aesthetics over anything else.

Special Features

If you are into additional features and more detailed evaluations, check for QoS functionality, USB ports for sharing data over the network, antennas relevant to the modem-router setup, etc. Depending on the availability of these specifications or lack thereof, the final price of the fiber-supported gateway device is determined.

Frequently Asked Questions
