The advantages of Passive Direct Attach Copper (DAC) cables over Fibre Optic and RJ45 cables Direct Attach Copper (DAC) cables are becoming increasingly in demand in the network industry. Our passive QSFP+ 40G DAC Twinax cable is an inexpensive alternative to RJ45 and fiber optic cables, with energy efficiency and low latency. It is an excellent choice for structured wiring over short distances between switches and routers on one side as well as servers and storage on the other, be it in Top of Rack (ToR), Adjacent Rack, 40G Stacking Switches or similar applications. No heat generation and suitable for extreme ambient temperatures - ideal for data centers QSFP+ DAC consists of twinaxial copper cable that has been placed on QSFP+ connectors at both ends and provides an electronic connection directly into the active components. Due to its thermal design, this passive cable consumes less than 0.15 W, which reduces your power consumption and thus your costs. As it does not produce heat, it is significantly more versatile, even at extreme ambient temperatures up to 70 °C, which in turn makes it particularly valuable for data centres. Cheaper and easier to use than fiber optic DAC wiring has a comparatively simple internal structure with fewer components than fiber optic cables. This cable structure allows for the lower purchase price and also saves you the purchase of separate GBIC transceivers. This in turn makes it easier to use as you need to match fewer components. When storing used cables, unlike fibreglass, you need to pay less attention to testing and cleaning before inserting them again. When you upgrade your network or replace individual parts, the cable's hot swapping capability ensures seamless transition. Just note that passive DAC cables are not suitable for long-distance use - their transmission range is limited to 7 metres. Lower latency than RJ45 twisted pair patch cable. This Direct Attach Copper Twinax cable allows data transfer up to 40 Gbps. Its unique structure and data transfer also ensures particularly low latency. Please note: this passive QSFP+ 40G DAC Twinax cable is MSA compliant and therefore designed, programmed and tested for use with switches and routers from Cisco, Intellinet Network Solutions, ZyXEL, TP-Link, Ubiquiti, D-Link, Edimax, A llllnet, all, all. ied Telesis, Digitus, KTI Networks, LevelOne, PLANET, Tenda, TRENDnet, ZTE, Avaya, Mikrotik, Enterasys, Finisar, Dell Force10, Riverstone, Fortinet and more.
