It is primarily used to connect Quantum-X800 QM3x00 switches to dual-800Gb\/s ConnectX-8 mezzanine adapters in liquid-cooled systems and ConnectX-8 PCIe adapters. The OSFP cages are located on the front panel of the compute tray for direct high-density connectivity. The module operates with 4 lanes of 200G-PAM4 electrical signaling, enabling two bits per clock cycle. On the optical side, it implements a single 4-channel DR4 interface over one MPO-12\/APC connector, supporting a datacenter reach of up to 500 meters over SMF. One MPO-12\/APC optical connector is used per transceiver.","brand":"SFPS","offers":[{"title":"MMS4A20-XM800","offer_id":47934115971293,"sku":"808-SFPS-MMS4A20-XM800","price":2249.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/7539\/1197\/files\/Product6034-1.png?v=1779069816","url":"https:\/\/www.sfps.qa\/products\/808-sfps-mms4a20-xm800","provider":"SFPS.QA","version":"1.0","type":"link"}
