100G SFP-DD 2 x 50G PAM4 to QSFP56 2 x 50G PAM4 Passive DAC, 0.5m (2ft)

The 100G SFP-DD 2 x 50G PAM4 to QSFP56 2 x 50G PAM4 Passive DAC, 0.5m (2ft) provides a 100Gbps copper connection between SFP-DD to QSFP56 ports with a cable length of 0.5m (2ft). As a passive cable it draws essentially no power and adds no latency to the link. Direct attach copper keeps both latency and power consumption to a minimum, which makes it the economical choice for 100G Ethernet data center and enterprise network environments.

Applications
Designed for 100G Ethernet data center and enterprise network environments, the 100G SFP-DD 2 x 50G PAM4 to QSFP56 2 x 50G PAM4 Passive DAC, 0.5m (2ft) carries 100Gbps between SFP-DD to QSFP56 interfaces. This unit is made in 4 standard lengths from 0.5m (2ft) to 3m (10ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs SFP-DD-2x 50G-PAM4QSFP56-2x 50G-PAM4 modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
Compliance: SFPDD: SFP-DD MSA, SFP-DD MIS, IEEE 802.3cdQSFP56: SFF-8661, SFF-8636, IEEE 802.3cd. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
Ordering Information
The part number for this assembly is SDD-100G-QPC005. We offer this cable in 0.5m (2ft), 1m (3ft), 2m (7ft) and 3m (10ft). Other lengths can be custom manufactured on request. Wire gauge: 30AWG. Samples for testing can be arranged before bulk orders.
Factory Custom Capability
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
How We Ship
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.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
