Questions & Answers

more+

Can this SFP+ module work at lower data rates (155Mbps) than specified?

Yes, it can work at 155Mbps.
What is the Tx power and Receiver Overload of 1G EX?

TX Power: -5 ~-0 dBm. Receiver Overload: -3 dBm
I notice that the 1G LX/LH supports both SMF and MMF. So what's the diffrence?

If you use MMF cables like OM2/OM3/OM4, the max diatance is 550m. If you use SMF cables, it can reach up to 10km. So you can choose cable type according to your application.

I purchased it to connect a TP-Link switch that only supports 10 Gigabit Ethernet to the rest of a gigabit network. It worked immediately without any problems.
