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.

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

7
Next Generation Networks

• Current networks - opaque and static
• Next generation networks - agile (flexible) and
  transparent
• Agile dynamically reconfigurable

8
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

9
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 multi-channel 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)

10
Scope of Dynamic Modules Standards Group

• Development of new standards for dynamic modules
• Some anticipated projects
• Control functions for signalling, telemetry,
  management, etc.
• Devices where states/paths are reconfigurable
• Optical Cross Connects
• Optical Add-Drop Multiplexers
• Dynamic Channel Equalisers
• Dynamic Gain Equalisers
• Dynamic Dispersion Compensators (polarization and
  chromatic)

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

13
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

14
Looking Forward

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

15
Summary

• Optical switching forms an important part of
  IECs 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
