It is the first time the operator has used third-party compatible optics in a core data centre project. Before deployment, our 800G OSFP module went through a full compatibility and stress test on NVIDIA InfiniBand equipment. This article explains how it was tested and what the results showed.<\/p>\r\n\r\n<div class=\"hm-stats\">\r\n  <div class=\"hm-stat\"><b>7.5 days<\/b><span>continuous full-speed run<\/span><\/div>\r\n  <div class=\"hm-stat\"><b>0<\/b><span>link drops or speed reductions<\/span><\/div>\r\n  <div class=\"hm-stat\"><b>&lt; 1 min<\/b><span>link recovery after restart<\/span><\/div>\r\n  <div class=\"hm-stat\"><b>5 \/ 5<\/b><span>plug-and-unplug cycles passed<\/span><\/div>\r\n<\/div>\r\n\r\n<h2>The Project: Optics for a Singapore AI Data Centre<\/h2>\r\n<p>AI training clusters move huge volumes of data between GPU servers, so every link in the fabric needs high bandwidth, low error rates and long-term stability. The operator needed 800G, 400G and 100G optics for its AI computing data centre. The modules had to work with the NVIDIA switches and network adapters already chosen for the cluster.<\/p>\r\n<p>Original-brand optics are a large share of an AI cluster's cost, and they can have long lead times. Third-party compatible transceivers are a practical alternative, but only when they are proven to behave exactly like the original parts on the target hardware. That is why the operator asked for a structured test on NVIDIA equipment before approving <a href=\"\/vi\/danh-muc-san-pham\/hydra\/optical-transceiver\/\">HydraX\u2122 optical transceivers<\/a> for its core project.<\/p>\r\n\r\n<div class=\"hm-figs\">\r\n  <img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/hermesys.com\/wp-content\/uploads\/2025\/02\/800g-\u5149\u6a21\u57573.jpg\" alt=\"HydraX 800G OSFP optical transceiver\" width=\"800\" height=\"800\" \/>\r\n  <img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/hermesys.com\/wp-content\/uploads\/2025\/02\/800g-\u5149\u6a21\u57572-1.jpg\" alt=\"HydraX 800G OSFP optical transceivers, flat top and finned top\" width=\"800\" height=\"507\" \/>\r\n<\/div>\r\n<p class=\"hm-cap\">Figure 1.

It is a hot-swappable multimode module that uses 100G PAM4 signalling and VCSEL lasers, supporting 800G interconnects over distances of up to 100 metres. In this test, it was paired with a 400G OSFP SR4 module on the adapter side over a 50-metre link.<\/p>\r\n\r\n<div class=\"hm-table-wrap\">\r\n<table>\r\n  <thead>\r\n    <tr><th>Item<\/th><th>Switch side<\/th><th>Adapter side<\/th><\/tr>\r\n  <\/thead>\r\n  <tbody>\r\n    <tr><td>Test equipment<\/td><td>NVIDIA QM9700 switch<\/td><td>NVIDIA MCX75310AAS-NEAT adapter (ConnectX-7)<\/td><\/tr>\r\n    <tr><td>Module model<\/td><td>OSFP-800G-2xSR4H<\/td><td>OSFP-400G-SR4H<\/td><\/tr>\r\n    <tr><td>Module type<\/td><td>OSFP (800G 2xSR4)<\/td><td>IB NDR, 400G-SR4<\/td><\/tr>\r\n    <tr><td>B\u01b0\u1edbc S\u00f3ng<\/td><td>Not applicable<\/td><td>854 nm<\/td><\/tr>\r\n    <tr><td>Test link distance<\/td><td>50 m<\/td><td>50 m<\/td><\/tr>\r\n    <tr><td>Port and link rate<\/td><td>IB1\/17\/1, NDR 400 Gbps<\/td><td>mlx5_0, 400 Gbps<\/td><\/tr>\r\n  <\/tbody>\r\n<\/table>\r\n<\/div>\r\n\r\n<h2>How We Tested Compatibility on NVIDIA Equipment<\/h2>\r\n<p>The test plan covers three areas: hardware compatibility, software compatibility and performance.

The HydraX\u2122 800G OSFP module in this article passed hardware, software and performance tests on an NVIDIA QM9700 switch and a ConnectX-7 adapter.<\/p>\r\n  <h3>What is the difference between 800G OSFP 2xSR4 and SR8?<\/h3>\r\n  <p>Both carry 800G over multimode fibre using eight 100G PAM4 lanes. A 2xSR4 module presents the eight lanes as two independent 400G ports, so one switch port can connect to two 400G adapters. This is the twin-port design used in NVIDIA InfiniBand NDR networks.<\/p>\r\n  <h3>How long should a transceiver be stress-tested before deployment?<\/h3>\r\n  <p>For core data centre links, a multi-day continuous run at full speed is a sensible baseline. In this project, the pass criterion was 7 days without interruption, and the module ran for 7 days, 12 hours and 43 minutes without a single link drop.<\/p>\r\n<\/div>\r\n\r\n<div class=\"hm-cta\">\r\n  <h2>Need Tested Optics for Your AI Data Centre?<\/h2>\r\n  <p>Hermesys supplies HydraX\u2122 800G, 400G and 100G optical transceivers, tested for compatibility with mainstream switches and network adapters, along with the high-speed cables and fibre cabling to connect them.<\/p>\r\n  <a class=\"hm-btn\" href=\"\/vi\/contact-us\/\">Li\u00ean h\u1ec7 v\u1edbi \u0111\u1ed9i ng\u0169 c\u1ee7a ch\u00fang t\u00f4i<\/a>\r\n  <a class=\"hm-btn hm-ghost\" href=\"\/vi\/san-pham\/hydrax-800g-osfp-sr8-transceiver\/\">View 800G OSFP Transceiver<\/a>\r\n<\/div>\r\n\r\n<\/article>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>(1-1: 800G OSFP Transceiver \u2013 Flat Top &amp; Finned Top) (1-2: One of Singapore&#8217;s leading data centers is now utilizing Hermesys 800G OSFP transceivers with the latest NVIDIA SN5600 switch) About SFP Transceivers Optical transceivers are high-speed modules essential for connecting network devices.
