The 100G SFP-DD 2 x 50G PAM4 to 2 x SFP56 50G PAM4 Passive DAC, 0.5m (2ft) is a passive twinax direct attach copper cable with SFP-DD to 2x SFP56, 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 802.3cdSFP56: SFF-8432, SFF-8402, SFF-8472, IEEE 802.3cd.

Applications
The 100G SFP-DD 2 x 50G PAM4 to 2 x SFP56 50G PAM4 Passive DAC, 0.5m (2ft) connects SFP-DD to 2x SFP56 ports at 100Gbps in 100G Ethernet data center and enterprise network environments. This unit is produced in 4 standard lengths from 0.5m (2ft) to 3m (10ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs SFP-DD-2x 50G-PAM4SFP56-1x 50G-PAM4 modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
Compliance: SFPDD: SFP-DD MSA, SFP-DD MIS, IEEE 802.3cdSFP56: SFF-8432, SFF-8402, SFF-8472, 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 factory part number is SDD-100G-2SPC005. This cable is available in 0.5m (2ft), 1m (3ft), 2m (7ft) and 3m (10ft). Lengths outside the standard range are made to order in our factory. Wire gauge: 30AWG.
OEM and Custom Orders
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.
Worldwide Delivery
We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
Reliability Control
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
Packaging Options
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.
