BizLink 400G QSFP-DD cables now available

BizLink, a premier provider of reliable, high-performance cabling for data centers, today announced the availability of its 400G QSFP-DD cable family. Targeting facilities needing maximum-density, high-bandwidth data traffic solutions, BizLink's new passive, direct attach cable family delivers affordable inter-rack connectivity able to meet the rising wave of global data center IP traffic, currently scaling at a compounded annual rate of 27 percent, according to Cisco. As hyperscale data centers seek feasible ways to accommodate this growth by migrating into 400 Gbit networking infrastructure, BizLink 400G QSFP-DD copper cabling can play a key role in containing costs while expanding infrastructure bandwidth.

Next-Gen Performance for Next-Gen Needs

As an increasing number of high performance computing environments and scaling data centers move to increase their network backbone bandwidth, port density remains a key concern as rack space may be constrained. Similarly, inter-rack connection costs can prove prohibitive, especially when based on fiber optics.

The QSFP-DD form factor is the industry's smallest 400G Ethernet design, enabling up to 36 400 GbE ports in a single rack unit. Concurrently, BizLink's QSFP-DD offers two passive copper cabling options: one with 16 copper wire pairs and the other with two 8-pair cable combined into a single assembly. Each product can transmit data at up to 50 Gb/s, yielding a maximum bandwidth of 400 Gb/s. Thanks in part to robust cable design and testing methodologies, combined with strict adherence to RoHS standards, BizLink cables deliver excellent functionality and durability without ballooning costs.

Each BizLink QSFP-DD cable utilizes an integrated 76-position “board-as-connector” design with zinc die-cast backshells for superior EMI performance and minimal insertion loss. The design provides eight independent data transmission channels via internal copper wiring. At the time of launch, BizLink offers three passive copper cable models for server and rack interconnects: 1, 2, and 2.5 meter lengths with gauges of 30, 28, and 28, respectively.

Quality and Compatibility

According to LightCounting market research, over 28 million 40 and 100 GbE modules will have been deployed by 2020. BizLink QSFP-DD cables are fully backward compatible with all QSFP56, QSFP28, and QSFP+ port equipment – no energy-wasting port adapters required. And again, working within this mature, high-volume market helps to keep costs low.

Every BizLink QSFP-DD cable is hot pluggable and integrates an EEPROM within the cable assembly, optionally programmable to better meet customer needs. With RoHS2 compliance, these cables are eco-friendly and efficient with heat dissipation. Their competitive pricing, high reliability, and excellent performance profile make them an idea cabling solution for communication systems, external storage systems, server racks, and similar high-bandwidth, low-latency solutions seeking to meet the needs of the coming decade.
