Product details
The MODM-B-12-8P8C-U-S4 by Samtec Inc. is a cutting-edge Modular Connectors - Jacks developed for next-generation data center applications. This high-density interconnect solution delivers superior signal integrity and thermal management, making it ideal for hyperscale computing and AI infrastructure.The Jack interface supports PCIe Gen5 and CXL protocols. QSFP-DD configurations enable 400GbE connectivity with backward compatibility to existing infrastructure.Featuring 8p8c (RJ45, Ethernet) optimized contact arrangement, this design reduces insertion loss to 0.3dB/mm at 16GHz. Compared to previous generations, it improves crosstalk isolation by 20dB.With 12 high-speed ports, the system supports breakout configurations for flexible network topologies. The 32-port version enables 1:4 cable splitting without signal degradation.The 2 row architecture maximizes PCB space utilization. Four-row configurations provide 112G PAM4 signaling in 1U rack space.Through Hole installation includes thermal-enhanced designs. The cold plate mount version dissipates 15W per port for high-power applications.90° Angle (Right) options facilitate efficient cable management. The mid-plane orientation reduces signal path length in blade servers by 40%.Solder technology features impedance-controlled solder tails. The press-fit version maintains 5% impedance tolerance for 112G applications.Shielded, EMI Finger system exceeds IEEE 802.3ck specifications. The overlapping shield design provides 85dB isolation at 28GHz.Cat3 include UL 1977 for data center equipment. OSFP versions support 800GbE optical interfaces.Board Lock incorporate thermal compensation for precise mating. The floating plate design accommodates 0.5mm PCB misalignment.The Does Not Contain LED diagnostic system supports intelligent monitoring. RGB variants enable port status indication through standardized color coding.Up and Down mechanism ensures secure mating in high-vibration environments. The dual-latch design withstands 50N of pull force.Phosphor Bronze formulation minimizes skin effect losses. Phosphor bronze with selective gold plating maintains <10m contact resistance.Gold plating ensures reliable high-speed performance. The 30 " gold over palladium nickel resists wear through 10,000 cycles.
