Can 10gb SFP Switch Port run at 1gb Switch Port ?
10G SFP+ Port on 10Gb Switch Consider 1G SFP Optics on Gigabit Switch generally in most Situations Will 1Gb SFP transceivers/modules use 10Gb SFP+ ports? The answer can be “Yes” in most cases. There are various vendors providing 10Gb switches that may consider both a 10G SFP+ and a 1G SFP in the 10Gb SFP+ slot, however, not simultaneously for apparent reasons. This program is supported by dual speed operation. So before plugging a Cisco SFP-10G-LR in to the SFP+ port on your own 10GbE switch, one must seek advice from your rep to ensure the 10Gb switch port support dual speed. To achieve link of 10Gb switch port to gigabit switch port, this is a simple guide. Use a 1Gb SFP module on the 10GbE switch SFP+ port and the gigabit switch 1Gb SFP port respectively, then connect the 10Gb switch and the gigabit switch with corresponding 1Gb SFP fiber cable or Ethernet copper cable (eg. Cat6). 1G SFP Port on Gigabit Switch Cannot Take 10Gb SFP+ Optics on 10Gb Switch in every Case...
