After entirely too long of a delay, the wait for faster consumer-grade network switches appears to be coming to an end. This week QNAP launched its QSW-1105-5T switch, one of the industry’s first unmanaged 2.5Gbps (2.5GBASE-T) switches. The 5-port switch supports 2.5GbE operation on all five of its RJ45 Ethernet ports, and along with being unmanaged it is also fanless, allowing the switch to work maintenance-free and installed virtually anywhere. The QSW-1105-5T is already on sale in Taiwan for roughly $100, meaning that we’re looking at a price-per-port of about $20.

The saga of NBASE-T has been something of a long one. First introduced in 2016, the standard added the then-new 2.5GBASE-T and 5GBASE-T modes, which were designed to offer a series of intermediate steps between the existing 1Gbps (1000BASE-T) and 10Gbps (10GBASE-T) standards. By scaling down parts of the 10GBASE-T spec, the new standards would allow more modest – but still many times faster – network transmission rates than 1Gbps Ethernet, all the while being able to reuse existing Cat5e and Cat6 cabling. Overall, 2.5GBASE-T allows for 2.5Gbps Ethernet over Cat5e at the same 100m distances as 1Gbps Ethernet, while 5GBASE-T allows for 5Gbps speeds over 100m runs of Cat6, as well as quasi-official support for shorter Cat5e runs.

Given the technology reuse, moderately-priced NBASE-T network cards were quick to hit the market. However affordable switches have been a more complex matter: while the high initial price of NBASE-T was easy enough to eat on a single controller, multiplied over several ports on a switch, it quickly drove up the price tag. As a result, the market for NBASE-T switches has largely between split between downgraded pro gear like Netgear’s $70-per-port XS505M, and mixed-port switches like Asus’s XG-U2008, which offer just two 10G/NBASE-T ports along with a slew of Gigabit Ethernet ports. So cheap NBASE-T networking options have remained elusive, at least until now.

Thankfully, in the last year we’ve finally started seeing the slower of the NBASE-T modes, 2.5GBASE-T, sprint towards wide adoption. The 2.5Gbps standard is the cheapest to implement, and with recent controller releases from the likes of RealTek and Intel, 2.5Gbps controllers have quickly become a staple on high-end motherboards. Accordingly, with the price per port coming down for 2.5Gbps controllers, it’s also bringing down the price of whole switches. And this is where QNAP’s new switch comes in.

The QSW-1105-5T is one of the first switches to be released using these new generations of cheap controllers. Aimed squarely at the home and SMB markets, the switch doesn’t offer any frills such as network management, Power over Ethernet, or SFP+ ports. Instead it focuses on the things that matter for the home market: supporting 2.5Gbps networking in a small, passively-cooled switch that’s suitable to be neglected by being tucked under a desk or in a closet.

QNAP QSW-1105-5T Switch
Speeds 100M/1G/2.5G
Ports (RJ45) 5
Managed No
Power 12 W
Dimensions 3.4 x 18 x 14.5 cm
Cooling Passive
Price ~$100

As the first of what will undoubtedly be many 2.5G switches over the coming months, the QSW-1105-5T also gives us our first real look at what we can expect from this generation of switches as far as footprints and power consumption goes. Since it’s not carved from a pro-grade switch, the 18 cm x 14.5 cm switch is significantly smaller than earlier NBASE-T switches. And with a maximum power consumption rating of 12 W, we’re looking at power consumption of just a bit over 2 Watts per port, which is also a significant improvement over admittedly far more powerful switches.

All of which sounds unremarkable, and indeed that’s exactly what makes the QSW-1105-5T so interesting. The biggest barrier to wide consumer adoption over the last few years has been the cost – both in regards to the core technology and added frills – so we’ve been waiting for quite a while to see NBASE-T technology transition from pro-grade switches to cheap, consumer-grade gear.

Otherwise, QNAP’s new switch is further evidence that the PC industry is going to coalesce around 2.5Gbps Ethernet for the time being. Besides being the fastest standard to officially and fully support Cat5e cabling – which was installed in walls en masse when home networking first took off – it’s also the cheapest and lowest-power option. This is allowing it to be widely deployed not only in new motherboards and cheap USB adapters, but finally in switches as well – and making QNAP’s new switch a good match for all of those new NICs. And while I’d like to see cheaper 5Gbps and 10Gbps gear as well, 5GBASE-T seems likely to remain a premium (if not niche) option, owing to the higher controller costs as well as its higher power consumption, both of which remain big problems for a switch.

At any rate, QNAP’s 2.5Gbps switch is on sale now in Taiwan. The company has not announced release dates elsewhere, but judging from some of their previous product releases, I’d expect it to start showing up in North America some time in the next few months.

    If you actually get anything near that - I did hit the gig Ethernet limit when they first upgraded me to gig speed, but the best I get the past few weeks is 650Mb.
    But transferring large files between my main desktop and my server - the GigE is definitely the bottleneck, if I had 2.5GbE I would definitely see faster transfers.

    If you are in one of the select areas where such speed is offered. Much of the comcast netowrk was limited to 50 Mbit downstream until 2 ish years ago, most STILL cant get the 1Gbit speed, and those that can cant maintain such speed for more then a few seconds.

    Are you one of those guys that says "go EBAY and buy 10gb switch!!" -- Wake up. Those are used, enterprise, LOUD, sometimes SFP-only devices that have no business in a home. SFP has no business in a home. Is your DSL/Cable modem SFP? Is your wireless AP SFP? Didn't think so.

    I'm happy to admit fault. But who else has a passively cooled, 4+ port (RJ45) switch for $100?
  • extide - Friday, July 17, 2020 - link

    Name one then.

    I've been searching for a long time to find an affordable switch. I was about to drop a ton of cash on the Netgear MS510TX ($650 AUD) because I couldn't find anything. This changes everything.
  • TheinsanegamerN - Monday, July 20, 2020 - link

    Ok, where? Name one. Because I cant think of any sub $100 2.5G switches that were redilly available for consumers.

    When can we start seeing 2.5Gbps Port on Routers.

    I mean you need to get Router sorted out first, otherwise the switch would be useless.
  • DanNeely - Friday, July 17, 2020 - link

    as long as all your 2.5gb items are attached to the switch, the connection from the switch to the router is irrelevant. the switch send the data from port A to port B via its internal connections.

    He's talking about >1Gb internet.
