SICSOLINK SFP-J06Q-HG2-US Management

As you would expect from such a basic, cheap switch, it is an unmanaged switch. So there is no management interface or other frills to show. It is plug-and-play.

SICSOLINK SFP-J06Q-HG2-US Performance

For this, we are using a Keysight XGS2 chassis with the NOVUS10/1GE16DP card. We are using an RFC2544 Quick Test for throughput with a few changes. For example, we increased the per-iteration run time to 30 seconds and started at 10% of the full line rate, searching for frame loss up to 100% of the line rate. We also test the RFC2544 64, 128, 256, 512, 1024, 1280, and 1518 byte frame sizes, and then add the standard IMIX, the Cisco IMIX, and an IPSec IMIX, which introduces mixed frame sizes into the testing. Let us start with 64B frame sizes.

The above may seem strange to some, so let us start with some of the key numbers. First, we observed no frame loss. We see almost 61Gbps of throughput, but at L1 it is almost 80Gbps. The delta is the overhead for the link, including headers and such. Still, we are showing line rate 8 ports of 10GbE even at 64B frame sizes.

Moving up to the 1518B frame sizes, these are in many ways much easier on hardware, and we can see closer to 79Gbps while the L1 rate is at 80Gbps. Again, bigger packets mean less relative overhead traffic in the pipe.

We add various IMIX tests, including the standard IMIX and Cisco IMIX profiles from Keysight. This sends packets of different sizes through the switch.

Those are maximum figures, but that is an insight that is very hard to generate unless you are using these high-end FPGA-based traffic generators.

We also have the IPSec IMIX test, which uses slightly larger average frame sizes in the mix. One item to note is that the green bar is all the way to the right on these charts on the ninth test iteration. That means that all ten test profiles hit 100% line rate during testing. Our gear and test methodology look for any frame loss during the testing, and we did not see any here.

SICSOLINK SFP-J06Q-HG2-US Power Consumption and Noise

The SICSLOINK is able to idle at 10 Watts as measured from the wall.

Powering up a single port adds just under two Watts in total, bringing it to 11.6 Watts.

Adding one 10Gbps SFP+ port adds 1.3 Watts from idle, bringing it to 11.3 Watts in total.

Often, when we test switches, the SFP+ to 10Gbase-T adds more power incremental consumption than lighting a 10Gbase-T port. In this case, it was reversed.

As noted earlier, this has a fan that generates some noise. It is in the 39-41dba range in our 34dba noise floor studio.

Final Words

This is certainly not a fancy switch. On the other hand, if you just need connectivity, a cheap unmanaged switch might be useful. Many of our readers might enjoy having all 10Gbase-T ports, but having a few SFP+ ports is nice just to tie into other types of switches or gear. While we did not get the heatsink off, it performed exactly how we would expect a Realtek RTL9303 to perform.

There is no way I would pay $500 for this switch. For under $200, it might be worth looking at. Also, from a brand like this, many prefer unmanaged switches. The big negative really is that it was far from a silent switch. On the other hand, from a deal perspective, I think many will like this type of switch over an 8-port 5Gbase-T switch since those are in the same price range.
