What is BS EN 62077- Fibre optic circulators about?
BS EN 62077 is a safety standard on fibre optic interconnecting devices and passive components.
BS EN 62077 applies to circulators used in the field of fibre optics bearing all
the following features:
- They are non-reciprocal optical devices, in which each port is either optical fibre or fibre optic connector
- They are passive devices in accordance with the categorization and definition provided in IEC TS 62538
- They have three or more ports for directionally transmitting optical power
Who is BS EN 62077- Fibre optic circulators for?
BS EN 62077 on fibre optic circulators is relevant to:
- Manufacturers of fibre optic interconnecting devices and passive components
- Manufacturers of fibre optic circulators
- Optical fibre technicians
- Fibre optic workers
- Testing authorities
Why should you use BS EN 62077- Fibre optic circulators?
Optical circulators are classified into styles based upon fibre type(s), connector type(s), cable type(s), housing shape and dimensions, and configuration.
Fibre optic circulators are classified as follows:
- Type
- Style
- Variant
- Normative reference extensions
Circulators are divided into types according to their configuration.
- Port numbers
Circulated type:
- Completely circulated type
- Incompletely circulated type
Operational principles:
- Magneto-optic Faraday effect
- Magneto-optic Cotton-Mouton effect and Kerr effect
Operating wavelength range:
- O-band
- C-band
- L-band
- Other wavelength circulators
Overall, BS EN 62077 is useful as it assists with the generic specification of fibre optic circulators which is part of a three-level IEC specification system.
What’s changed since the last update?
