QSFP28 100G DACs


Modulelink 100G direct attach copper cable assembly (DAC) is suitable for very short distances and offers a highly cost-effective way to establish a 100 Gigabit link connectivity between devices using QSFP28 ports. The QSFP28 DAC cable is designed for 100Gb/s high-speed interconnecting networking applications such as high-performance computing (HPC), enterprise networking including top-of-rack switching and network storage markets. The QSFP28-100G DAC copper cable is programmed to be compatible with a wide range of network equipment for intra-rack connections in data centers such as 100GE Switches, Routers, Network Interface Cards (NICs) and Network Storage Systems.

QSFP+ 40G DACs


Modulelink 40G direct attach copper cable assembly (DAC) is suitable for very short distances and offers a highly cost-effective way to establish a 40 Gigabit link connectivity between devices using QSFP ports. The QSFP+ DAC cable is designed for 40Gb/s high-speed interconnecting networking applications such as high-performance computing (HPC), enterprise networking including top-of-rack switching and network storage markets. It fully complies with QSFP+ Multi-Source Agreement (MSA) standards SFF-8436 and IEEE 802.3ba 40GBASE-CR4. The QSFP+ 40G DAC copper cable is programmed to be compatible with a wide range of network equipment for intra-rack connections in data centers such as 40GE Switches, Routers, Network Interface Cards (NICs) and Network Storage Systems.

SFP28 25G DACs


Modulelink 25G SFP28 DAC cables offer precision external cable assembly solutions. They meet the ever increasing demand for higher channel density with high-level signal integrity in high performance computing, top-of-rack switching, and network storage deployments. The DAC cables extremely low-insertion loss due to the unique foam skin, gas-injected dielectric technology as well as extreme control of balanced/unbalanced (Mode conversion). The technology offers ease of cable management and smaller packaging densities. The cable assemblies employ new, innovative PCB technology designed specifically to deliver signal integrity performance. The cables regulate cross talk and launch conditions between wire and PCB termination to optimize return loss and prevent or minimize “ringing” effects.
