ETSI EN 300 386
ETSI EN 300 386 is the electromagnetic compatibility standard for telecommunication network equipment. This article explains its scope, emission and immunity requirements, and Compatible Electronics' accredited testing services. Part of the Compatible Electronics Learning Center.
What is ETSI EN 300 386?
ETSI EN 300 386 is a product family standard published by the European Telecommunications Standards Institute (ETSI) specifying electromagnetic compatibility (EMC) requirements for telecommunication network equipment. It covers both emission requirements and immunity requirements for equipment that forms part of public or private telecommunication networks.
The standard is a harmonized standard under the EU EMC Directive (2014/30/EU), meaning compliance with ETSI EN 300 386 supports the presumption of conformity with the directive's essential requirements and enables CE Marking of telecom network equipment. Compatible Electronics provides NVLAP-accredited ETSI EN 300 386 testing services.
Equipment Covered
ETSI EN 300 386 applies to equipment that forms part of, or connects to, a telecommunication network, including:
- Central office and exchange equipment (switching systems, DSLAM, OLT)
- Base transceiver stations and radio network equipment
- Network routers, switches, and access equipment in carrier-grade installations
- Optical line terminals and multiplexers
- Power systems for telecom installations
- Cable distribution equipment
Note the distinction between customer premises equipment (CPE) — which typically falls under product family standards such as CISPR 32 or the Radio Equipment Directive — and network equipment covered by EN 300 386.
Emission and Immunity Requirements
1
Emissions
EN 300 386 references CISPR 22 (now CISPR 32) emission limits for conducted and radiated disturbances. Class A limits apply for most telecom network equipment installations, reflecting the controlled nature of network equipment rooms and central offices rather than public-access environments.
2
Immunity
EN 300 386 specifies immunity test levels appropriate for telecom network environments, including ESD (IEC 61000-4-2), radiated immunity (IEC 61000-4-3), EFT/burst (IEC 61000-4-4), surge (IEC 61000-4-5), conducted RF (IEC 61000-4-6), power frequency magnetic field (IEC 61000-4-8), and voltage dips (IEC 61000-4-11).
