Note: This update is based on the results of the May 2026 VITA Standards Organization (VSO) meeting, held in Tempe, Arizona. Contact VITA if you are interested in participating in any of these working groups. The full reports can be accessed at www.vita.com/StandardsUpdates. Visit the VITA website (http://www.vita.com) for details on upcoming VITA meetings.
ANSI accreditation
Accredited as an American National Standards Institute (ANSI) developer, VITA provides its members with the ability to develop and promote open technology standards.
The following standards have recently been approved via public VITA consensus ballot:
- ANSI/VITA 48.5-2026: Mechanical Standard for VPX REDI Electronic Plug-In Modules Using Air Flow Through Cooling
- ANSI/VITA 78.0-2026: SpaceVPX System Standard
- ANSI/VITA 90.0-2026: VNX+ Base Standard
- ANSI/VITA 90.1-2026: VNX+ Profile Tables
- VITA 90.2-2026 VDSTU: VNX+ Optical and RF Connector Modules – Type
- ANSI/VITA 90.3-2026: VNX+ Power Supply and Storage Modules
- ANSI/VITA 90.4-2026: VNX+ Cooling and Mounting Systems
- ANSI/VITA 90.7-2026: VNX+ Optical and RF Connector Modules – Type 7
All published standards are available for download by VITA members and are posted at the online VITA Store for purchase by nonmembers.
VSO study and working group activities
Standards within VITA may be initiated through the formation of a study group and developed by a working group. A study group requires the sponsorship of one VITA member, while a working group requires sponsorship of at least three VITA members.
Several working groups have current projects underway. Here’s a roundup of these projects:
VITA 46.32: VPX Connector Supporting 56 Gbaud Class Data Rates
Abstract: This standard defines a VPX connector that supports data rates to 56 Gbaud, for protocols such as 200GBASE-KR4 Ethernet and PCIe Gen 5. These connectors are intermateable to legacy VITA 46.X backplane connectors and follow the same form factor.
Status: Working group has developed a draft document that is ready for public review.
VITA 48.9: VPX AFT Cooling – Retractable Seals
Abstract: This standard defines an AFT module format, 3U and 6U, that uses retractable module rack seals to improve module-chassis seal durability, simplifies the design by eliminating tapered module and chassis features, and allows easy migration of existing CCA designs to an air-cooled module format.
Status: Working group is developing a draft document.
VITA 92: High Performance Cable – Ruggedized 10 Gbaud Bulkhead High Speed, D-Sub, Rectangular Connector for Copper Cables
Abstract: This standard defines a rugged standardized 10 Gbaud interconnect system with a high pin count and high-density, lightweight, rectangular connector (meets MIL-DTL-24308 physical envelope) for I/O. It can support multiple high- bandwidth protocols and power while optimizing SWaP [size, weight, and power] benefits in smaller systems with limited panel space availability.
Status: The public review phase has completed and the document is being prepared for publication.
VITA 93.1: QTM – QMC I/O Transition Module
Abstract: This standard complements the VITA 93.0 QMC standard by detailing the mechanical design of a mezzanine card installed on a carrier card or rear-transition module, enabling the transition of QMC I/O signals to industry-standard connectors accessible through the carrier card’s or rear transition module’s front panel.
Status: Working group developing draft document.
VITA 93.3: QMC – Stacking Coax
Abstract: This standard defines a small-form-factor mezzanine based on the existing QMC standard but replacing the I/O connector with blind-mate 50-ohm or 75-ohm coaxial connectors. This is intended to allow for easy integration between mezzanines and carriers using high-performance coaxial connections for RF/IF or video applications.
Status: Working group developing draft document.
VITA 94.0-2024xNew: Power Distribution Plug-In Module
Abstract: This standard provides requirements for building a power distribution plug-in module with digital controls that can be used in a VPX chassis. The plug-in module will fit within the standards envelope defined for VPX modules in the VITA 48.x standards.
Status: Working group is developing a draft document.
VITA 95.0: Circular 38999 Connector with EBO Fiber Technology
Abstract: This document defines a standard for circular connectors with Expanded Beam Optical (EBO) ferrules. Circular connector shells are compliant to MIL-STD-38999 Series III. EBO ferrules are available in multimode or single mode.
Status: Working group is developing a draft document.
VITA 96.0: Backplane Connectors with EBO Fiber Technology
Abstract: This document defines a standard for backplane connectors with EBO ferrules. EBO ferrules are available in multimode and single mode.
Status: Working group is developing a draft document.
VITA 100.x: VPX 100
Abstract: The VPX 100 suite of standards is an evolution of OpenVPX, VPX, and related mechanical standards while embracing a paradigm shift in technology and capability with at least double the pin density, speed, and power for electrical contacts.
Status: Working group is nearing release of several of the standards to VITA Trial Use and public release expected this summer.
