About SFP Transceivers
SFP transceivers are high-speed modules essential for connecting network devices. They facilitate the conversion between electrical and optical signals. Known for their high data rates, long-distance transmission capabilities, strong anti-interference features, high security, and energy efficiency, SFP transceivers are integral to modern high-performance networks and communication systems. They play a crucial role in supporting large-scale data transmission and internet connectivity.
To assess the comprehensive strength of an SFP transceiver, we will evaluate a dual-port 800Gb/s SFP transceiver developed by NVIDIA for InfiniBand and Ethernet. Our evaluation will focus on three key aspects: hardware compatibility, software compatibility, and performance. The transceiver’s parameters must meet industry standards and be compatible with NVIDIA’s AI network series switches and ConnectX-7 VPI network cards.
It’s important to note that the 800G OSFP SR8 SFP transceiver module is a hot-swappable device designed for 800G SR8 Ethernet links in data centers. This module leverages the latest 100G PAM4 and VCSEL technologies, allowing for 800G data interconnections over distances of up to 100 meters.
Compatibility Testing on NVIDIA Devices
(2-1: Physical Connection)
Test Items | Test Details | |
Hardware Compatibility Testing | Plug and Unplug Test | After plugging and unplugging the equipment more than five times, the module should still fit securely in the NVIDIA switch and network card port slot, without becoming loose or stuck. |
Port Restart Test | Restart the switch or network card using device commands. The link should be restored within three minutes after the restart. | |
Power Off and Restart Test | After powering off and restarting the device, the link should be restored within five minutes. | |
Software Compatibility Testing | Connectivity Test | The module should establish a connection with devices at both ends normally, and the device port status should indicate “up.” |
Shutdown / No Shutdown Test | After manually shutting down and then reopening the switch or network card port, the link should reconnect normally. | |
Parametric Testing | The module’s part number (PN), version number (VN), serial number (SN), and other information read by the device should match the module label description. | |
Performance Testing | DDM Test | Read the module’s Digital Diagnostic Monitoring (DDM) data when the device is linked and monitor whether the five DDM parameters exceed their thresholds. |
Bit Error Rate Test | Measure the real-time bit error rate. | |
Stability Test | Conduct the test continuously for 7 days in transmission mode, ensuring that the link remains uninterrupted and there is no reduction in speed. | |

(2-3 Plug and Unplug Test – Device)
The SFP transceiver can be properly inserted into ports on both ends of the device. After insertion, the transceiver fits snugly in the device port and shows no signs of looseness. It can be smoothly removed from the port by pulling the module latch, with no notching or obstruction. After a hot or cold reboot of the switch or network card, and following a system restart, the link should recover within 1 minute.
