Support PCIe Gen 5/6 with CDFP

The data centers are carrying a significant amount of the workload, stressing existing infrastructures and accelerating the need for upgrades. These drive the development of disaggregated and composable architectures that leverage pooled resources of compute, memory, storage and hardware acceleration. Our CDFP technology enables a x16 link width within a single port and will be scalable to support x8 and x4 channels. As the industry upgrades from PCIe Gen 5 to PCIe Gen 6, the connector footprint migrates from press-fit to surface mount technology (SMT). We also offer the passive copper cable which is typically used for current hyperscale / cloud applications.

  1. CDFP Connector & Cage Assembly: 400 Gbps Pluggable I/O (English)

To help meet today’s growing demand for pluggable I/O solutions ’s to deliver greater bandwidth and space efficiency, TE Connectivity introduces the CDFP connector & cage assembly, a 400 Gigabit per second Pluggable I/O for high speed applications such as data centers, high performance computing, as well as storage and networking equipment.

One of the Highest Port and Bandwidth Densities
  • With 11 CDFP ports, a 1U switch can deliver 4.4 Terabits per second of bandwidth or more.
  • 16 x 25 Gbps electrical interface = 400 Gbps per port
  • 0.75mm pitch, 120 contacts, dual row paddle card interface
Supporting Current and Next Generation Designs
  • Fully compliant with the multi-source agreement (MSA), which specifies a 400 Gbps module, connector and cage that integrate 16 TX/RX channels.
  • MSA specifies CDFP connectors and cage assembly which support active optical cables, optical transceivers and copper cables.
  • The low power (8-10W) and very low power (4-5W) form factors defined use a common interface.
  • CDFP modules for data center interconnects support five-meter direct attach cables, 100-meter multimode fiber, 500-meter parallel single-mode fiber, and two kilometers of duplex, single-mode fiber.
  • TE provides CDFP Style 2 30AWG cable with 7.9mm OD for up to 2.0M cable reach
