100G SFP-DD 2 x 50G PAM4 to QSFP56 2 x 50G PAM4 Passive DAC

For short reach 100Gbps links in 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) offers a factory terminated passive twinax assembly with SFP-DD to QSFP56 connectors and a length of 0.5m (2ft). As a passive cable it draws essentially no power and adds no latency to the link. The cable meets SFPDD: SFP-DD MSA, SFP-DD MIS, IEEE 802.3cdQSFP56: SFF-8661, SFF-8636, IEEE 802.3cd.

Product Highlights

The 100G SFP-DD 2 x 50G PAM4 to QSFP56 2 x 50G PAM4 Passive DAC, 0.5m (2ft) connects SFP-DD to QSFP56 ports at 100Gbps in 100G Ethernet data center and enterprise network environments. This unit is supplied 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. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing. The link runs SFP-DD-2x 50G-PAM4QSFP56-2x 50G-PAM4 modulation, which keeps it aligned with current 100G switch silicon.

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.

This model carries part number SDD-100G-QPC005. You can order this assembly in 0.5m (2ft), 1m (3ft), 2m (7ft) and 3m (10ft). Non-standard lengths can be produced on request. Wire gauge: 30AWG. Volume pricing is available for project quantities.

Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.

Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.

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.
