What are the differences between the SB7800 and SB7890 switches? Are there any differences in product selection?

The SB7800 and SB7890 switches have no differences in terms of functionality and performance. The SB7800 comes with a management port, while the SB7890 is non-managed (out-of-band management). NADDOD's products can be used on both devices, and their performance is the same. Therefore, there are no differences in product selection.

What fiber optic cable should be used for interconnecting with QSFP-100G-CWDM4H?

QSFP-100G-CWDM4H has a duplex LC interface, so it can be used with standard single-mode fiber optic cables terminated with LC connectors.

What are the differences between 100G EDR and 100G HDR100?

100G EDR is 4x25G NRZ, and 100G HDR100 is 2x50G PAM4. EDR devices are not compatible with HDR100.

Questions & Answers

Ask a Question

Where can I download FW for QM8700 IB switch?

QM8700 do not have FW file. Because managed systems do not require Firmware updating. Firmware updating is done through the MLNX-OS management software. You can download the firmware updating file in the Resources section of the QM8790 listing, or click here for other QM87XX series switches firmware updating user manual.

If hypothetically we had a problem where we don’t know if the issue is with the NADDOD cables or with the Mellanox switches, or maybe Mellanox switch failure due to cable's problem, would you provide us technical support？

Of course. No matter what problem you have, you can just contact us directly. NADDOD will provide technical support: including switch and network configuration services to help you find out and solve problems.And please make sure: AOC/DAC cables or transceivers are networking interconnection accessories, which essentially are just a connection of signal transmission and don't cause any hardware or software problems to the original devices. NADDOD Test Center recreates a 100% original environment for testing all parts of our IB products to provide customers the highest quality and performance.

Whether the InfiniBand cables can be used on Ethernet switches？

Yes, InfiniBand cables can be used for both IB and Ethernet, but Ethernet cables can only be used for Ethernet.
