The 100G SFP-DD 2 x 50G PAM4 to QSFP56 2 x 50G PAM4 Passive DAC, 0.5m (2ft) is a passive twinax direct attach copper cable with SFP-DD to QSFP56, supporting 100Gbps links over a length of 0.5m (2ft). 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 100G Ethernet data center and enterprise network environments, and complies with SFPDD: SFP-DD MSA, SFP-DD MIS, IEEE 802.3cdQSFP56: SFF-8661, SFF-8636, IEEE 802.3cd.

The 100G SFP-DD 2 x 50G PAM4 to QSFP56 2 x 50G PAM4 Passive DAC, 0.5m (2ft) is a 100Gbps direct attach copper cable for SFP-DD to QSFP56 connections in 100G Ethernet data center and enterprise network environments. This unit is available in 4 standard lengths from 0.5m (2ft) to 3m (10ft). Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.

This product is designed and tested to comply with SFPDD: SFP-DD MSA, SFP-DD MIS, IEEE 802.3cdQSFP56: SFF-8661, SFF-8636, IEEE 802.3cd. It plugs into any standards-based SFP-DD to QSFP56 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

The standard part number of this assembly is SDD-100G-QPC005. We supply this cable in 0.5m (2ft), 1m (3ft), 2m (7ft) and 3m (10ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 30AWG. Samples for testing can be arranged before bulk orders.

As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.

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.

Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.

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.
