800G OSFP IHS/Finned Top to 2 x 400G OSFP RHS/Flat Top Passive Copper Breakout DAC Cable

The 800G OSFP IHS/Finned Top to 2 x 400G OSFP RHS/Flat Top Passive Copper Breakout DAC Cable is a passive breakout dac direct attach copper cable with OSFP (IHS/Finned Top) to 2x OSFP (RHS/Flat Top), supporting 800Gbps links over a length of 0.5~3m (2~10ft). As a passive cable it draws essentially no power and adds no latency to the link. It is a cost effective, low latency interconnect for 800G Ethernet data center and cloud network environments, and complies with OSFP MSA Rev5.0, IEEE 802.3ck, CMIS 4.0.

The 800G OSFP IHS/Finned Top to 2 x 400G OSFP RHS/Flat Top Passive Copper Breakout DAC Cable connects OSFP (IHS/Finned Top) to 2x OSFP (RHS/Flat Top) ports at 800Gbps in 800G Ethernet data center and cloud network environments. This unit is supplied at 0.5~3m (2~10ft). By fanning one port out to 2x OSFP (RHS/Flat Top), it doubles or quadruples the number of endpoints served per switch port and keeps the cabling plant simple. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs 8x 100G-PAM4 to Dual 4x 100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.

This product is designed and tested to comply with OSFP MSA Rev5.0, IEEE 802.3ck, CMIS 4.0. It plugs into any standards-based OSFP (IHS/Finned Top) to 2x OSFP (RHS/Flat Top) port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

This model is supplied at 0.5~3m (2~10ft) under part number OSFP-800G-2OFLPCxxx. Other lengths of the same assembly can be produced on request. Wire gauge: 26~30AWG. Volume pricing is available for project quantities.

Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.

Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.

Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.
