## Long description

Short 0.3 m network patch cable from DIGITUS, model 21.45.3321. This Cat6a cable features U/FTP (individually foil‑shielded twisted pairs) shielding and shielded RJ‑45 connectors on both ends with gold‑plated contacts. The thin, flexible construction and yellow jacket make the cable suitable for high‑speed Ethernet links in confined installations where space and identification are important.
Advantages
The U/FTP (STP) design with individual aluminium‑laminated foil around each pair improves rejection of electromagnetic interference compared with unshielded cables. The cable is particularly thin and flexible, which facilitates routing in crowded racks and tight cable-management paths. Molded kink protection at the connectors increases durability and reduces strain on the terminations during frequent handling or tight bends. The bright yellow jacket supports easy visual identification in patch panels and cable bundles.
Suitable for
Short patch connections between switches and patch panels in racks
Device-to-patch‑panel links in confined spaces and dense cabling environments
High‑speed Ethernet connections requiring Cat6a performance over very short runs
Organized cable management where color coding aids identification

How to use
Use this DIGITUS Cat6a patch cable for short interconnects in network racks, between switches and patch panels, or as a device connection cable where a compact, shielded link is required. Insert the RJ‑45 plugs fully into the corresponding shielded RJ‑45 ports until the latch clicks. Route the cable through cable guides or management channels to avoid sharp bends and to maintain the shielding performance. For best results, keep the run length short as intended (0.3 m) and avoid tightly compressing the cable in cable trays.
Usage recommendations
The cable is intended for use in LAN environments and confined spaces such as data centre racks. Avoid routing alongside high‑power electrical lines that could introduce interference and ensure connectors and ports are compatible with shielded RJ‑45 terminations for optimal performance.
