IEC 60794-3-30:2008

Overview

IEC 60794-3-30:2008 - "Optical fibre cables - Part 3-30: Outdoor cables - Family specification for optical telecommunication cables for lakes, river crossings and coastal application" is an IEC family specification for underwater optical fibre cables used in lakes, river crossings and coastal environments. It defines minimum requirements, cable description templates (blank detail specifications), mechanical/environmental tests and fibre performance criteria for outdoor underwater deployments. This edition updates the title to explicitly include coastal applications, adds fibre Type B5, and includes an annex with additional requirements mapped to the MICE table.

Key topics and technical requirements

• Scope and exclusions
  • Covers underwater optical telecommunication cables for lakes, rivers and coastal crossings.
  • Does not cover repair methods or cable repair capability, nor cables for line amplifiers used in such crossings.
• Fibre types and optical performance
  • Defines acceptable single-mode fibre families: B1.1, B1.2, B1.3, B2, B4 and B5 (B5 newly included).
  • Specifies attenuation limits for cabled fibres (examples from the standard):
    • 1310 nm:
