Just bought one to test with both Mikrotik RB4011 and CRS309. The other endpoint was a Verizon CR1000A which supports 1/2.5/5/10G.
The module supports NBaseT even if the SFP+ port doesn't. Eg RB4011.
Some changes I needed to make to the SFP+ settings:
1. To establish 1G connection, I had to set the SFP+ interface to a fixed 1G rate.
2. For 2.5/5/10G, I could leave auto-negotiation on. SFP+ interface still reports 10G rate, but CR1000A confirmed the NBaseT rate was used.
There's no DDM reporting with this module.
I also saw a
thread about issues with the module expecting the port to be enabled during startup, else it would appear offline unless reinserted due to TX_disable pin being connected to PHY directly. However, I saw no such issues despite restarting and/or unplugging power to the RB4011.
Overall, this seems like a good successor to both the Fibermall 80m variant (which doesn't support NBaseT) and S+RJ10 (which supports NBase-T but runs too hot). The major advantage over the S+RJ10 and AQS107 is the ability to support 10G over relatively short runs of Cat5E. Only downside is no DDM reporting.
