Description (English):

IEC 61755-3-10: 2016 defines certain dimensional limits of a 125 mm diameter single mode silica fibre optical interface and an alignment bore to meet specific requirements for non-angled fibre-to-fibre interconnection as defined in IEC 61755-2-1. The silica fibre materials specified in this document are suitable for use in categories C, U, E and O as defined in IEC 61753-1.

Abstract

Overview

IEC 61755-3-10:2016 specifies dimensional and material limits for non-angled, ferrule-less, bore alignment connectors used with non-dispersion shifted single‑mode physically contacting fibres (125 µm cladding). The standard defines the optical interface geometry between fibre end faces and the alignment bore to ensure reliable, low‑loss non‑angled fibre‑to‑fibre mating in accordance with the performance requirements of IEC 61755-2-1. Materials and mechanical constants for the silica fibre are also given to support predictable contact deformation and optical performance.

Key topics and technical requirements

Scope: Interfaces for 125 µm diameter single‑mode silica fibres in ferrule‑less, bore‑aligned connectors.
Critical geometric parameters (representative ranges from the standard):
- End face radius: 4–10 mm
- End face angle: 0–0.7°
- Chamfer angle: 25–65°
- Tip diameter: 0.03–0.08 mm
- Core concentricity error: 0–0.0006 mm (0–0.6 µm)
- Cladding diameter: 0.1240–0.1260 mm (124–126 µm)
- Bore diameter: 0.1260–0.1270 mm (126–127 µm)
- Bore length: ≥ 0.55 mm
Mechanical and material requirements
- Minimum contact force: 0.6 N
- Fibre material: fused silica
- Nominal physical constants: Young’s modulus 72.7 ± 7 GPa, Poisson’s ratio 0.165 ± 0.015
Alignment and loss drivers covered: lateral offset, angular offset, longitudinal offset, and end‑face deformation - all linked to the listed dimensions.
Purpose: ensure attenuation targets of IEC 61755-2-1 are met for the specified wavelength and mode field conditions.

Applications and who uses this standard

Connector designers and manufacturers developing ferrule‑less, bore alignment single‑mode connectors.
Test laboratories and quality control teams validating connector dimensions and contact performance.
System integrators and OEMs in telecommunications, datacom, and instrumentation who require standardized, low‑loss, non‑angled fibre interconnections.
Materials engineers verifying silica fibre properties and contact mechanics for connector reliability.
Useful when specifying components for environments/categories C, U, E, and O per IEC 61753‑1.
