Overview

SIST EN 2591-606:2004 is a European aerospace standard developed by the European Committee for Standardization (CEN) under the guidance of the European Association of Aerospace Manufacturers (AECMA). This standard specifies a precise test method for measuring crosstalk-both forward and backward-of light between multi-channel optical connection elements used in aerospace electrical and optical systems.

Designed to ensure reliable and predictable performance of optical components in aerospace applications, SIST EN 2591-606:2004 is essential for manufacturers and testers working with multi-channel optical connections in demanding aerospace environments. It should be used in conjunction with EN 2591-100, which provides general testing requirements for aerospace electrical and optical connection elements.

Key Topics

• Scope and Purpose
  The standard defines a method to measure the optical crosstalk, which is the unwanted transfer of light signals between adjacent channels in multi-channel optical connectors. It addresses measuring both forward and backward crosstalk to ensure component quality and signal integrity.

• Specimen Preparation
  Specimens must be equipped with standard accessories and fully terminated contacts, adhering to detailed product specifications that include the type and length of fiber optic cables and allowable crosstalk limits.

• Test Apparatus
  Testing requires a Light Launch System (LLS) and Light Detector System (LDS) compliant with EN 2591-100 specifications, along with temporary joints and non-reflective terminators defined by EN 2591-601 and related parts.

• Testing Procedure
  The method involves inserting the specimen mid-cable, exciting one optical fiber, and measuring the optical output power in an adjacent fiber at both ends using detectors. These values enable calculation of crosstalk in decibels (dB), quantifying the leakage of optical signals.

• Calculation of Crosstalk
  Forward crosstalk (dB) = –10 log(Pf / Po)
  Backward crosstalk (dB) = –10 log(Pb / Po)
  where Po is the input power, Pf the forward power output, and Pb the backward power output from adjacent fibers.

Applications

• Aerospace Optical Systems
  SIST EN 2591-606:2004 is critical for testing optical interconnection elements in avionics and aerospace communication systems, where optical signal integrity and minimal interference are paramount.

• Quality Assurance in Manufacturing
  Manufacturers of multi-channel optical connectors and related components use this standard to verify that their products meet strict aerospace requirements for crosstalk.

• System Integration and Maintenance
  Aerospace integrators and maintenance teams apply the testing methods to diagnose optical performance issues, prevent signal degradation, and assure compliance with aerospace operational standards.
