Patchbox Plus Cat. 6A Cassette. Retractable patch cables for perfect patching. Replaceable modular cassette system. RJ-45 - RJ-45, Cat 6A. STP shielding, cable jacket: PVC. Length: 2.5 m, Black, Flat, Retractable. Retractable patch cables for the perfect length. Replaceable modular cassette system with integrated cassette labeling. Cable stopper for precise cable length adjustment, compatible with PBXFRAME. The patchbox is a modern cabling system for network cabinets, replacing conventional cable management and patch cables. Through an innovative mechanism, the patchbox provides patch cables in the correct length. This has elevated the industry standard to a new level: a completely new type of cable management in network cabinets that drastically speeds up all workflows. Shielded Twisted Pair (STP). This STP cable is a symmetrical cable with twisted and shielded pairs. Shielded cables exhibit minimal impedance or reactance deviations compared to unshielded ones. The transmission parameters remain relatively constant and better than those of UTP cables, even at high frequencies. Category 6A. Category 6 augmented (Cat 6A) is a standard that arises from the increased bandwidth requirements of 10-Gigabit Ethernet (10 GBASE-T). Cat 6A cables are designed for transmission frequencies up to 500 MHz and distances up to 100 m, and are backward compatible with existing categories.
