Fibre Optic Standards Activities in the IEC
• International Electrotechnical Commission fibre optic
standards activities centre around TC86
• IEC TC86 scope: ‘To prepare standards for fibre optic
systems, modules, devices and components intended
primarily for use with communications equipment.’

Standards Engineering
Passive Components
• Most of the work to date on optical switching standards,
focussed in IEC SC86B WG7, Passive Components
• IEC SC86B WG7 have developed standards on:
–
–
–
–
–

Spatial switches
Wavelength switches
Medium scale (16-128 channel) MxN switches
WWDM devices
DWDM devices
Standards Engineering
Next Generation Networks
• Current networks - opaque and static
• Next generation networks - agile (flexible) and transparent
• Agile = dynamically reconfigurable
7
Standards Engineering
Enabling Agile Transparency
• Products needed to enable agile transparency:
– Optical transport technology that extends the distance
between optical to electronic conversions
– Optical switching technology that adds little cost or signal
degradation to through traffic
• Many companies working on such products

Standards Engineering
Dynamic Modules
• An important class of products are not currently being
addressed in IEC TC86
• Differentiating features:
– alter and control the inter-relationship of channels in a multichannel device.
– provide flexible connectivity or conditioning, rather than being
fixed (i.e. dynamic not static).
• Some elements span across subgroups in IEC TC86
• Agreed to form a new group under TC86 called “Dynamic
Modules” (TC86 WG8)

Standards Development
• Dynamic Module performance standard proposals multifaceted:
–
–
–
–
–
Module performance standard
Component performance standards
Electrical interface
Embedded software
Physical objective [longer term]
• Draw on existing IEC standards wherever possible:
– Components (e.g. IEC SC86B WG7)
– Test methods (e.g. IEC SC86B WG4)
• Ensure effective harmonization with ITU standards through
liaison with SG15 Q17
12
Standards Engineering
Current Activities
• Request for participation of interested experts - Feb 2002
• Prioritise projects taking into account availability of experts
– Performance Standard for Dynamic Channel Equalizer
– Reliability Qualification Standard for Dynamic Modules
– Performance Standard for Dynamic Polarization Mode
Dispersion Compensators
– Performance Standard for Dynamic Chromatic Dispersion
Compensators
– Software/Hardware Interface Standard
– General and Guidance for Dynamic Modules

Standards Engineering
Looking Forward
• Continue development of existing standards proposals
• Review and address new submissions
• Next IEC TC86 WG8 meeting - 28th October 2002, Beijing,
PRC

Summary
• Optical switching forms an important part of IEC’s standards
activities
• IEC TC86 WG8 established to address market need for
standards to support dynamically reconfigurable networks
• Recognition that internal and external liaison is important to
ensure harmonization and avoid duplication
