  1. 1. Teleste Proprietary. All rights reserved. Company confidentialTeleste Proprietary. All rights reserved. Company confidential Teleste’s power-saving innovation - Reduce operational costs and save nature Customer Seminar April 5, 2019, Maastricht Rami Kimari VP, HFC business
  2. 2. Teleste Proprietary. All rights reserved. Company confidential Agenda • Introduction • Power save study • Implementation status
  3. 3. Teleste Proprietary. All rights reserved. Company confidential Introduction
  4. 4. Teleste Proprietary. All rights reserved. Company confidential Capabilities vs utilisation
  5. 5. Teleste Proprietary. All rights reserved. Company confidential Saving potential RF amplifier components consume 70% of all power in outside plants Our solution saves up to 30% of power used by the RF amplifier components  Save up to 20% of your cable network power consumption
  6. 6. Teleste Proprietary. All rights reserved. Company confidential The core idea of Teleste solution Many optical nodes and amplifiers are optimised for a speculative situation: • Full RF load • Maximum signal levels In practice: • Highest frequencies are not used • Required RF levels are lower than maximum
  7. 7. Teleste Proprietary. All rights reserved. Company confidential Three novel options to save power in practice #1 Remotely adjusted performance levels #2 Autonomous performance adjustment #3 Load-based performance adjustment
  8. 8. Teleste Proprietary. All rights reserved. Company confidential #1 Remotely adjusted performance levels • Power save modes are used to set optimal amplifier bias current based on the total RF load • Modes are enabled by operators, locally or remotely
  9. 9. Teleste Proprietary. All rights reserved. Company confidential #2 Autonomous performance adjustment • Power save modes are used to set optimal amplifier bias current based on total RF load • Linear and dynamic power save modes are enabled automatically • No need for local or remote access
  10. 10. Teleste Proprietary. All rights reserved. Company confidential #3 Load-based performance adjustment • RPD analyses total RF load • Analysis is used to set right amplifier bias current, leading to optimal power consumption • Operation is autonomous

  18. 18. Teleste Proprietary. All rights reserved. Company confidential #1 Remotely adjusted performance levels • Teleste’s all classical HFC node and amplifier platforms include 2 step based (enabled/disabled) power save function • Remote control is available with transponders (DOCSIS/HMS) and coming with unidirectional RIS control • Compact line extender amplifier (E3) is the first design that supports power save control with RIS receiver
  19. 19. Teleste Proprietary. All rights reserved. Company confidential #2 Autonomous performance adjustment • Power save trigger level is defined for compact line extender amplifier (E3) • Broadband RF load power meter module (E62) has a release candidate • RIS module (E62) supports remote control and software update • Further platform implementations are under discussions
  20. 20. Teleste Proprietary. All rights reserved. Company confidential #3 Load-based performance adjustment • RPD node platforms support adjustable power save function • RPD module will report load content information in Q2/2019 • Knowledge of load information and adjustable power save function will be implemented to 4 active output strand mounted node platform (ICON9000) during Q2/2019 • Further platform implementations are under discussions (DAN300, AC9100 NEO)
