QSA Adapters Get Even Better at 25Gb/s

QSA solves problems linking different port sizes and speeds equipment together Problems: You have a 4-channel QSFP port on a switch or network adapter but you’ve got a single-channel subsystem that uses SFP and you want to connect older equipment, storage or a 10G device. Or you have a new shiny 25Gb/s-based Spectrum switch or […]

DesignCon Trade Show – Connecting All the Signaling Dots

Stop by Booth #120 to see Mellanox 25G and 100Gb/s DAC, AOCs, SR4, PSM4 Cables and Transceivers DesignCon at the Santa Clara Convention Center, to be held Jan. 31-Feb. 2, is the “chippie geek” trade show of the year and you better know how to speak PAM4 fluently this year if you attend. Electronic signaling […]

Short Reach Optics in Modern Data Centers

Spanning Across the Data Center or Breakouts Within the Rack Short Reach (SR) multi-mode optics are the lowest priced optical interconnects available today that use optical connectors to separate the transceiver from the optical fibers. Although both support 100m reach, AOCs are much less expensive that SR optics but the former functions as a complete […]

AOCs – Active Optical Cables Why are 2 transceivers and fibers priced less than one connectorized transceiver?

This blog is Part 2 in a 3-part series on Mellanox’s high-speed interconnect products. My first blog covered Direct Attach Copper (DAC) cables which are the least expensive way to create a high-speed 25G/50G/100Gb/s interconnect, but have a maximum reach of about 3-5 meters. Active Optical Cables (AOCs) pick it up from there and can reach up to 100-200 meters and are the least expensive, optical links available. Widely used in HPCs and more recently became popular in hyperscale. enterprise and storage systems.

Mellanox Launches 200Gb/s HDR InfiniBand AOC and DAC LinkX® Cables

Just when you started to get familiar with 100Gb/s EDR–along comes 200Gb/s HDR doubling the bandwidth Quick Summary Last week at the HPC supercomputer conference SC’16 in Salt Lake City Utah, Mellanox announced its 40-port, 200Gb/s HDR InfiniBand line of Quantum-based switches and dual-port ConnectX®-6 host bus adapters. To link them all together, we also […]

16 Ways LinkX DAC Cables are “Breaking Out” All Over Servers and Storage

Part I of Three Part Blog Series on Cables & Transceivers CAT-5e cabling and 1GBASE-T have dominated the data center interconnect scene for 15 plus years. However, the transition to 10G Ethernet proved to be a significant hindrance in both power consumption and cost. That’s when Direct Attach Copper (DAC) cabling, aka Twinax, snuck in […]
