The passive MUX/DEMUX unit, CWDM, allows to combine 8 fiber links into one, saving costs. Its high-power wireless cards in miniPCI-e format feature LED indicators, TX and RX activity, and more. Its concentrator Gateway cards support 8 different channels. The network interface cards have 2x SFP28 cages for 25G networking. MikroTik’s 40Gbps optical QSFP+ module provides connection over 100m on OM3 MMF and 150m on OM4 MMF. You can connect two of these switches to QSFP+ to QSFP+ direct attach cables. Or connect them to 4 other 10G SFP+ devices with QSFP+ to SFP+ cables. Besides, we have SFP+ to SFP+ cables and cables supporting SFP 1G, SFP+ 10G, and 25G SFP28 standard.
