The Optical Fiber Conference was in San Diego Mar 4-7th with 16,000+ attendees and 700 booths. OFC is LinkX’s biggest show of the year as it focuses on future products and was all about 200G/400G using with 50G PAM4 modulation.
The Mellanox LinkX team showed an incredible 6 live demonstrations!
Also shown was our complete line of 25G/50G/100G DAC and AOC cables and optical transceivers with our 25/100G-based network adapters, and network switches (underneath in picture below). Mellanox designs and build its own InfiniBand and Ethernet switches and adapter ICs and manufactures the adapter boards and switch chassis as well. In addition, Mellanox’s LinkX team designs multi-mode and single-mode transceiver ICs and builds its own DAC, AOC and transceiver products. Unlike many other suppliers, Mellanox designs and manufactures the entire switch-cable/transceiver-adapter link. This enables us to provide outstanding product performance by matching circuit internals to optimize the signal integrity and guarantee optimal performance. One of our key selling points is a BER rating for cables and transceivers of 1E-15 pre-FEC compared to competitors post-FEC.
Keysight/Ixia was kind enough to lend us one of their new QSFP-DD test chassis where together we demonstrated:
The screen shot below shows amazing Pre-FEC Bit Error Ratio numbers that most cables and transceiver suppliers achieve Post-FEC processing in the switch! This demonstrates the high manufacturing quality of the parts – one of Mellanox’s key value-add.
This is a carry over from our cables and transceiver manufacturing for the InfiniBand market where FEC introduces way too much latency delay in the sytem to be used. InfiniBand EDR switches have an 80-ns port-to-port latency and FEC needs about 120ns to compute. We apply these high-quality manufacturing techniques to the Ethernet product line to offer the best BER ratings in the industry – important when you are computing at 100G and any errors can jamb up the system and induce retrnsmission delays.
100G cables and transceivers are in full swing in the market and rapidly being adopted in hyperscale, HPC, enterprise and storage. Mellanox offers a complete line of switches, PCIe and OCP form-factor network adapters including cables and transceivers for 100G and now 200G that are shipping. Two times the bandwidth at only a slight premium in price above 100G systems and links. In spite of all the conference and market noise, 400G complete end-to-end systems are still a way off and will see more of the pieces come together in late 2020 and 2021.
