Description (English):

IEC 61754-7-2:2017 defines the standard interface dimensions for the type MPO family of connectors with two rows of fibres. This first edition of IEC 61754-7-2, along with the first edition of IEC 61754-7-1, cancels and replaces the third edition of IEC 61754-7 published in 2008. This first edition of IEC 61754-7-2 includes the two fibre row MPO variants including the addition of active device receptacles and up-angled plugs. The first edition of IEC 61754-7-1 includes the one fibre row MPO variants and related active device receptacles and up-angled plugs. Keywords: interface dimensions for the type MPO family of connectors with two rows of fibres

Abstract

Overview

IEC 61754-7-2:2017 specifies the interface dimensions for the type MPO family of connectors with two rows of fibres. This first edition defines standardized mechanical interfaces for MPO connectors carrying 16–24 fibres arranged in two rows. It updates and splits the previous IEC 61754-7 (2008) into two parts (61754-7-1 for one-row variants and 61754-7-2 for two-row variants) and adds support for active device receptacles and up-angled plugs.

Key topics and technical requirements

Standard interface dimensions for the MPO two-row family, enabling consistent mating across manufacturers.
Connector geometry: the parent MPO ferrule is typically 6.4 mm × 2.5 mm and uses two 0.7 mm alignment pins.
Fibre counts and arrangement: supports arrays of 16 to 24 fibres in a two-layer (two-row) configuration.
Connector types covered:
- MPO female plug (without pins) and MPO male plug (with fixed pins)
- Angled interfaces: down-angled and up-angled plugs
- Flat interfaces
- Adaptors with opposed or aligned keyway configurations
- Backplane and printed circuit board housings
- Active device receptacles (angled and flat interfaces)
Mechanical features and mating:
- Push–pull coupling mechanism and ferrule spring loaded toward the optical axis
- Single male key to orient and limit relative mating position
- Defined intermateability rules: which plug types and adaptor/key configurations can mate (opposed vs aligned keyways determine compatible up/down or mixed angled plugs)
Documentation includes detailed figures, gauge definitions and dimensional tables to support design and conformity assessment.
Note on intellectual property: the standard flags potential patent claims related to MPO connectors and lists known contacts; implementers should review patent information.

Practical applications and users

IEC 61754-7-2 is used by:

Connector and cable manufacturers designing compliant MPO plugs, adaptors, housings and active-device receptacles
Data center architects and system integrators specifying high-density MPO deployments for 40/100 G and parallel optics
Equipment designers creating backplane/PCB receptacles and optical transceiver modules
Test labs and quality teams verifying intermateability and dimensional conformance
Standards and procurement teams ensuring cross-vendor compatibility for multi-fibre MPO links

Adopting IEC 61754-7-2 ensures reliable mechanical mating, predictable alignment, and interoperability for two-row MPO assemblies.
