RT2 High-Speed Backplane Connectors for VPX (VITA 46)
VITA 46 · 6.25 Gbps (to 10 Gbps) · press-fit
VPX Rugged Hybrid Backplane Connectors (VITA 46 / 66 / 67)
6.25 Gbps · RF to 40 GHz · MT fiber · 3U and 6U
VPX connectors build a standard VITA module interface from separate modules: press-fit 100 Ω differential modules for 6.25 Gbps, VITA 67 RF modules to 18 or 40 GHz, VITA 66 fiber modules with high-density MT ferrules, single-ended and power modules. One connector carries RF, optical, differential, single-ended and power signals for 3U and 6U boards.

Frequently asked questions
Can one VPX connector carry RF and fiber?
Yes. VITA 67 RF and VITA 66 fiber modules can sit in the same connector as differential and power modules.
Do you supply 3U and 6U versions?
Yes, plus rear-transition versions. Tell us the module layout by position (P0–P6).
