Do switches need to have optical ports Why
To meet these growing bandwidth requirements, access switches must have optical downlink ports. An all-optical Ethernet switch is a network switch whose service ports are entirely optical, meaning every interface uses fiber rather than copper. This design enables end-to-end optical signal transmission, avoiding the conversion between electrical and optical signals at the switch port level. So you get a full SFP switch then buy a bunch of copper/rj45 tranceivers? Just be careful with SFP+.
