BS EN 62077:2016

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? 

BS EN 62077:2016 supersedes BS EN 62077:2010 which is withdrawn. 

BS EN 62077:2016 replaces the second edition published in 2010. BS EN 62077:2016 constitutes a technical revision. 

BS EN 62077:2016 includes the following significant technical changes with respect to the previous edition: 

• Harmonization of some terms and definitions with other generic specifications 
• Deletion of assessment level
