Yes, the FS.COM 40GBASE-SR4 QSFP+ transceivers can be be used in a 4 x 10G mode for interoperability with 10GBASE-SR interfaces, making it easier re-use 10G components when developing 40G. The connectivity is achieved by using an 8 fibers OM4 MTP®-LC Type B harness cable #68047, which connects the 40GBASE-SR4 transceivers to four 10GBASE-SR optical interfaces.2017年5月13日にT***rより発表された
