{"product_id":"3m-10ft_3109","title":"3m (10ft) 400G OSFP 8 x 50G PAM4 Flat Top to 400G QSFP-DD 8 x 50G PAM4 Passive Direct Attach Copper Twinax Cable for FS Switches","description":"\u003cstrong\u003eDescription\u003c\/strong\u003e\u003cbr\u003eThe 400G OSFP to 400G QSFP-DD DAC provides a 400G copper direct-attach solution with a Flat-top (OSFP-RHS) form factor, suitable for very short links and offers a cost-effective way to establish a 400-Gigabit link between 400G ports of switches\/routers within racks and across adjacent racks. It is compliant with OSFP MSA, QSFP-DD MSA and IEEE 802.3bs standards.\nThis DAC is designed with ultra-low loss materials, square rings, twisted pair cable 8 wires and shell extension construction for superior mechanical properties and bending performance. It supports 8x50G PAM4 modulation on both ends, and is primarily used to connect a 400G QSFP-DD switch to OSFP-based 400G network adapter cards. It is tested in actual switching systems to ensure optimal signal integrity and the best end-to-end performance, ideal for SDN, ML, and Cloud Computing.\nNote：When the 400G OSFP Flat Top to QSFP-DD DAC is used with NVIDIA ConnectX-7 OSFP NICs, ensure the NIC firmware version is between 28.42.1000 and 28.44.1206 to guarantee stable 400G 8x 50G PAM4 link performance.","brand":"Refurb Squared","offers":[{"title":"3m (10ft) \/ Cisco","offer_id":51425421230368,"sku":"RefurbCisco24142","price":840.43,"currency_code":"AED","in_stock":true},{"title":"3m (10ft) \/ Juniper","offer_id":51425421263136,"sku":"RefurbJuniper24143","price":840.43,"currency_code":"AED","in_stock":true},{"title":"3m (10ft) \/ Arista","offer_id":51425421295904,"sku":"RefurbArista24144","price":840.43,"currency_code":"AED","in_stock":true},{"title":"3m (10ft) \/ NVIDIA (ETH)","offer_id":51425421328672,"sku":"RefurbNVIDIA (ETH)24145","price":840.43,"currency_code":"AED","in_stock":true},{"title":"3m (10ft) \/ Dell","offer_id":51425421361440,"sku":"RefurbDell24146","price":840.43,"currency_code":"AED","in_stock":true},{"title":"3m (10ft) \/ Broadcom","offer_id":51425421394208,"sku":"RefurbBroadcom24147","price":840.43,"currency_code":"AED","in_stock":true},{"title":"3m (10ft) \/ Generic","offer_id":51425421426976,"sku":"RefurbGeneric24148","price":840.43,"currency_code":"AED","in_stock":true},{"title":"3m (10ft) \/ FS","offer_id":51425421459744,"sku":"RefurbFS24149","price":840.43,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/3157\/9936\/files\/202509061806142dar7o_jpg_7a0b60ab-0dc3-4967-ba00-b2198efb15c9.webp?v=1775374164","url":"https:\/\/www.refurb2.com\/products\/3m-10ft_3109","provider":"Refurb Squared","version":"1.0","type":"link"}
