Create a short 10 GbE interconnect between adjacent SFP+ interfaces with a 30 cm passive twinax direct-attach copper cable. The fixed SFP+ to SFP+ assembly carries 10GBASE-CU traffic without separate optical modules or fiber patch leads. Its short reach suits connections where ports, servers, storage, or network equipment are installed in the same rack or immediately adjacent equipment positions. AddOn Networks EX-SFP-10GE-DAC-30CM-AO is built for Juniper Networks-compatible SFP+ connections and uses the EX-SFP-10GE-DAC-30CM interface format. Direct-attach copper keeps the link path compact: the transceiver ends and copper cable are one factory-assembled component. That construction avoids selecting separate SFP+ optics, matching fiber type, and patch-cable length for a very short link. The 30 cm length is the defining choice within a direct-attach cable range. It is intended for tightly grouped equipment rather than cross-rack cabling, helping keep short interconnects contained near the ports they serve. Use it where both endpoints provide 10 GbE SFP+ connectivity and the required cable route remains within 30 cm. The cable is TAA compliant for deployments that require that designation.
