BS EN IEC 62149-5:2020

What is BS EN IEC 62149‑5 about?  

BS EN IEC 62149‑5 is part five of the multi-series standard which is on ATM-PON transceivers with LD driver and CDR ICs. 

BS EN IEC 62149‑5 specifies performance on the transceiver modules for asynchronous transfer-mode passive optical network (ATM-PON) systems recommended by the International 

Telecommunication Union (ITU) in ITU-T Recommendation G.983.1. 

Who is BS EN IEC 62149‑5 for? 

BS EN IEC 62149‑5 on ATM-PON transceivers with LD driver and CDR ICs is useful for: 

• Fibre optic cables manufacturers  
• ATM-PON transceivers and manufacturers  

Why should you use BS EN IEC 62149‑5?  

Fibre optic transceivers are used to convert electrical signals into optical signals and vice versa. 

The optical performance criteria are generally well specified for a number of internationally agreed applications areas such as ITU-T Recommendation G.983.1 and IEEE Std 802.3.  

BS EN IEC 62149‑5 aims to assure inter-changeability in performance between fibre optic transceivers for ATM-PON (ATM-based broadband passive optical network) systems supplied by different manufacturers but does not guarantee operation between fibre optic transceivers. 

Performance testing is undertaken to assure reliability of products when characterization testing is complete. BS EN IEC 62149‑5 gives the procedure for performance testing. 

BS EN IEC 62149‑5 provides description of the transceiver module and provides environmental specifications for the ATM-PON transceiver. 

What’s changed since the last update?  

BS EN IEC 62149‑5 is the third edition that replaces the second edition published in 2009 and constitutes a technical revision. 

BS EN IEC 62149‑5 includes the following significant technical changes with respect to the previous edition: 

• Description of types in Clause 4 has been removed 
• Titles of reference documents have been updated
