Mellanox LinkX™ Cables and Transceivers
Transition to Optics
After 10+ years of 1G/10GBase-T, and coupled with the advent of hyperscale computing, the data center is undergoing rapid changes. Architectures are changing, line rates and aggregate data rates are dramatically increasing, low bit error rates and low latency requirements have spiked.
As the number of links in a data center increases and at increasing data rates, the reach of 25G-based copper DAC has maintained 3-5-meter reach and 100 meter 10GBASE-T is taking a long time to jump to 25GBASE-T. DAC took over the server uplinks when 10GBASE-T stalled in the market and optical transceivers and AOCs became the way to span greater than 3-5 meters upwards in the switching infrastructure.
Two years ago, the average optical fiber reach in enterprise data centers was <30 meters. Today, it is over 50 meters and climbing. In hyperscale data centers, the average reach is now 150 meter and climbing. Most leaf-spine links are near 300 meters long and 2Km single-mode transceivers such as PSM4, LR4-lite and CWDM4 types are becoming very popular.
While enterprise data centers are now moving up to 10G/40G line rates, many jumping straight to 25G/100G realizing benefits of a small price premium over 10G but 2.5 times the bandwidth. Moving even faster are hyperscale companies already deploying 25G/100G and preparing to jump to 200G/400G in both front panel pluggable and embedded form-factors.
As the number of links and data rates increase and link reaches become longer, low-power consumption, low Bit Error Ratio (BER), and low latency are becoming very important.
Mellanox LinkX 100G Interconnect Product Line
Mellanox designs end-to-end systems including switches and network adapter as well as a complete line of cables and transceivers in copper and optical SFP and QSFP form factors and at data rates form 10, 25 40, 50, 100Gb/s and soon 200Gb/s, all specifically designed for modern data centers. Transceivers and AOCs are available in both multi-mode and single-mode fiber types and Ethernet, InfiniBand and 24G CPRI protocols.
Mellanox designs its own transceivers and transceiver control ICs, hence can optimize the interface between electronics and optics in ways others who buy generalized off-the-shelf ICs and build transceivers cannot. Mellanox also designs, manufactures and builds its own Silicon Photonics ICs for building single-mode 2km, PSM4 transceivers and use Mellanox transceiver control ICs as well.
This vertically integrated approach brings customer benefits of low-power, low-latency and low-bit error ratios, and enables the links to achieve full performance and a better data center ROI.
Low power, latency and bit error ratio enables higher performing cables and transceivers to maximizes server and switch uplink performance, nearly eliminating retransmission from data error.
