To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I have edgerouter4 and gs110tp, i bought two of those in the hope of connecting the router to the switch via sfp.
Upon connection, nothing happened, no green light, nothing. I left them in their boxes thinking that i didn't do enough research to ensure compatability.
As a last resort, i decided to contact 10gtek and ask for advice. I got a response within few hours stating some troubleshooting steps trying to pin down the problem.
The first suggestion was to try another fiber cable which i didn't have and i had to buy it, once arrived, i connected it and the green lights came up on both the router and the switch, so far so good!
Thanks a lot Freya from 10gtek for the quick response and the helpful suggestions.
These work pretty great. I wish my switches supported 10Gb SFP+ ports, but the switches I have will only support the 1.25Gbps SFP switches. These are not only a great price, they work flawlessly with cisco switches. I have a catalyst 3950 (an older model from 2k6) and I have a SG-220 26p switch for small/medium business and they will xfer the full bandwitdth at low latency to one another.
The ASF85-24-X2-Cisco2 model worked perfectly in both my EnGenius Neutron EWS1200-52T and Amcrest AGPS9E8P-AT-96 (a.k.a. BV-Tech POE-SW802-DIN) switches. Now that I have changed from copper to fiber for the switch-to-switch connection, I have better electrical isolation between the PoE switch running my exterior IP cameras and my main switch in case of power spikes. As a bonus, I've had no heat issues with these SFPs like others have mentioned. They run nice and cool for me and I've had 0 dropped packets.
