1.1 Product definition This document contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements which a terminated and assembled 12 fibre multimode MPO connector set (plug adapter plug) meet in order for it to be categorized as an EN standard product. Since different variants are permitted, product marking details are given in 5.2. 1.2 Intermateability All products conforming to the requirements of this document will intermate and give the specified level of random attenuation and random return loss performance. The intention is that this will be true irrespective of the manufacturing source(s) of the product. 1.3 Operating environment The tests selected combined with the severity and duration are representative of a backplane/back panel indoor application derived from customer premises protected environment as defined in EN 50173 series and ISO/IEC 11801 series and specified as category C in EN IEC 61753 1. 1.4 Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this document does not guarantee the reliability of the product. This is expected to be predicted using a recognized reliability assessment programme. 1.5 Quality assurance Compliance with this document does not guarantee the manufacturing consistency of the product. This is expected to be maintained using a recognized quality assurance programme.

Overview

prEN 50377-15-1 is a draft CLC product specification for 12‑fibre MPO connector sets terminated with PPS ferrules on EN 60793-2 category A1a 50/125 µm multimode (macrobend‑enhanced) fibre. The document defines the initial start‑of‑life dimensional, optical, mechanical and environmental requirements that a terminated plug–adapter–plug MPO assembly must meet to be classified as an EN standard product. It is intended to ensure supplier‑independent intermateability and predictable performance in indoor backplane/back‑panel customer premises environments.

Key topics and technical requirements

• Product definition and scope
  • Terminated and assembled 12‑fibre MPO (plug / adapter / plug) with rectangular, spring‑loaded ferrule and precision pin/hole alignment.
  • Specifically for 50/125 µm macrobend‑enhanced multimode fibre (EN 60793‑2 category A1a as referenced in the draft).
• Intermateability
  • Requirements ensure all compliant products will intermate and meet specified random attenuation and return‑loss performance irrespective of manufacturer.
• Performance parameters
  • Start‑of‑life dimensional limits (outline and mating‑face geometry, ferrule end‑face parameters).
  • Optical metrics (random mated attenuation, return loss grades, end‑face polish/physical contact).
  • Mechanical tests (mating durability, vibration, impact, tensile/cable retention, torsion, strain‑relief flexing).
  • Environmental tests (temperature extremes, damp heat, change of temperature, static side load).
• Testing and qualification
  • Test methods drawn from EN 61300 series (e.g., vibration, mating durability, attenuation of random mated connectors, return loss).
  • Sample size, pass/fail criteria, and product qualification requirements for dimensional, optical, mechanical and environmental performance.
• Marking and variants
  • Rules for variant identification and product marking to accommodate permitted product variants.

Applications and who uses this standard

• Manufacturers of MPO connectors, ferrules and adapter assemblies - for product design, verification and conformity claims.
• Component suppliers and system integrators specifying high‑density multimode interconnects in indoor protected environments (backplanes, patch panels, equipment panels).
• Test laboratories and quality/qualification teams applying EN/IEC test methods to certify start‑of‑life performance and intermateability.
• Procurement and standards engineers writing technical specifications for multimode MPO assemblies where macrobend performance is required.

Each pin-hole shall accept a gauge pin as shown in Figure 8 to a depth of 5,5 mm with a maximum force of 1,7 N. In addition,
two pin-holes of a plug shall accept a gauge as shown in Figure 9 to a depth of 5,5 mm with a maximum force of 3,4 N.
b
Dimension C is defined as the distance between two pin-hole centres.
c
Dimension I is given for a fibre end face centre of a plug end when not mated. It is noticed that a ferrule is movable by a
certain axial compression force, and therefore the dimension I is variable. Ferrule compression force shall be 7,8 N to 11,8 N
when the position of the fibre end face from the datum Z is in the range of 8,2 mm to 8,4 mm.
d
Coupling sleeve shall be movable by a certain axial compression force. Dimension L is given for a coupling sleeve end when
not mated. Coupling sleeve compression force shall be 2,9 N to 6,9 N when the position of the coupling sleeve end face from
datum Z is in the range of 0 mm to 0,1 mm to the right or to the left of datum Z.
e
The plug shall be uncoupled from the adaptor when the end face of the coupling sleeve is moved by a distance greater than
2mm to the left of datum Z.

192 NOTE 1 The optical datum target diagram is shown in the figure. The optical datum targets are located on a line X
193 passing through the two pin-hole centres and located on or symmetrically about a line Y perpendicular to line X located
194 midway between the two pin-hole centres.
