DAC cable is often used in short-distance cabling schemes in data centers. Compared with other AOC active optical cable and optical module transmission schemes, it has high performance cost ratio , but the short transmission distance is its limitation. If the equipment spacing exceeds the length of direct attach cable, it is necessary to choose AOC active optical cable and optical module scheme. T...

In this article, ETU-LINK will analyze common problems related to 40G QSFP+ optical modules, 40G QSFP+ AOC active optical cables, and 40G QSFP+ DAC high-speed cables. Q1：Can a 40G optical module be connected with a 10G optical module? A1: Not all 40G optical modules can be connected to 10G optical modules, only 4*10G parallel transmission optical modules can be connected to 10G optical modules, fo...
