As we all know, the 40G SR4 QSFP+ optical module is the ideal solution for short-range interconnection in 40G networks and has many advantages, but the 40G QSFP+ AOC also has similar function of optical module and is not inferior to the 40G SR4 QSFP+ module or even can replace it to transmit signals. Since both can be 40G short-distance interconnection, then what are the differences between them? ...
