NOTE

All numerical values are in metric units [with U.S. customary units in brackets]. Dimensions are in millimeters. Unless

otherwise specified, dimensions have a tolerance of ±0.13 and angles have a tolerance of ±2°. Figures and illustrations are

1. INTRODUCTION

This specification covers the requirements for the VMEbus International Trade Association (VITA) 66.4 Fiber-

Optic Connectors with use with Multi-Mode MT Ferrules. This connector system has been designed for use as

independent or stand-alone connectors in ANSI/VITA 48.1 (air-cooling applications) and ANSI/VITA 48.2

(conduction-cooling applications) applied to printed wiring boards (PWBs)/plug-in units defined in ANSI/VITA

46.0 VPX systems. Typical applications are in the aerospace and defense industry and include use in adverse

environments for Embedded Computing, Processing, Avionics and Vetronics, Radar, Secure Communications

and Imaging/Targeting.

The connector system provides a high-density, blind-mate optical interconnect in a backplane/card

configuration. The fiber-optic (ribbon) cable interconnect is fed through the backplane to removable systems

modules using standard-grade Multi-Mode MT ferrules. The connector system consists of the backplane

connector and the mating module connector which interconnects a single ferrule, accommodating up to twelve

fiber paths.

When corresponding with TE Connectivity Personnel, use the terminology provided in this specification to

facilitate inquiries for information. Basic terms and features of this product are provided in Figure 1.

2.6. Standards and Publications

ANSI/VITA 46.0, “VPX Baseline Standard”, developed by the VMEbus International Trade Association (VITA)

describes the VITA 46 VPX family of standards for VMEbus systems for the provision of high-speed

interconnects in harsh-environment applications.

ANSI/VITA 47, “American National Standard for Environments, Design and Construction, Safety and Quality for

Plug-In Units Standard”, developed by VITA, defines environmental, safety, and quality requirements for

commercial-off-the-shelf (COTS) plug-in units (cards, modules, etc.) intended for mobile applications.

ANSI/VITA 48.1, “Mechanical Specification for Microcomputers Using REDI Air Cooling”, developed by VITA,

defines the mechanical requirements that are needed to ensure the mechanical interchangeability of air-cooled

3U and 6U plug-in units and define the features required to achieve two level maintenance compatibility.

ANSI/VITA 48.2, “Mechanical Specification for Microcomputers Using REDI Conduction Cooling Applied to

VITA VPX”, developed by VITA, defines the mechanical requirements that are needed to ensure the

mechanical interchangeability of air-cooled 3U and 6U plug-in units and define the features required to achieve

two level maintenance compatibility.

ANSI/VITA 66.0, “Optical Interconnect on VPX - Base Standard”, developed by VITA, defines a family of blind-

mate fiber-optic interconnects for use with VPX backplanes and plug-in modules.

ANSI/VITA 66.4, “Optical Interconnect on VPX – Half Width MT Variant”, developed by VITA, defines the half-

size fiber-optic interconnect variant for the MT style contact.

IEC 61755-3-31, “Fiber-Optic Connector Optical Interfaces - Part 3-31”, which defines the MT ferrule end face

geometry requirements.
