5.0 out of 5 stars Works for 1GB Unifi USW-24-PoE switch to UDM-Pro
Reviewed in the United States on July 15, 2021
Number of Items: 1Verified Purchase
I used two of these devices to connect an Unifi USW-24-PoE switch to UDM-Pro, also using a [0.5 Meter (1.6FT) Multimode Duplex Fiber Optic Cable (62.5/125) - LC to LC - Orange, Brand: Ultra Spec Cables]. The UDM-Pro can handle 10 GB or 1 GB, but the USW-24-PoE gen. 1 only has a 1GB port. The 10 GB devices will not work in the USW, and the same device needs to be at each end of the optic cable to work. Using this setup freed up two additional RJ45 ports at my Network rack. Also, since my internet is about 920 GB download, I don't need the 10GB devices anyhow, as only internet traffic is coming to a from the UDM (UNVR-4 does Protect video, not the UDM). It is all working great with this setup, nothing special had to be done, plug and play...
