Published on

DEFCOM, India’s most important Defense event covering all 3 Sister Services – Army, Navy & Airforce lived up to its expectations in 2011. Cisco participated in a major way and ensured its sessions and demos all aligned to the event's theme- “Enabling Information and Communication Technologies (ICT) for Info Age Warfare". Cisco expert Suhas Mansingh, Senior Director presented a paper on ‘Emerging Optical Transport Technologies & Architectures' and Arif Shouqi spoke on ‘Strategic Approaches to security of Defense Networks: A Practical Blueprint'. Cisco showcased two LIVE demos at our booth- WSON (Wavelength Switched Optical Network) and Security Encryption Demo supported by SRE-N

  5. 5. CP: Coherent Polarized  Leverages on Polarization Multiplexing to transmit with Lower Baud Rate (e.g. 40Gbps as 10GBaud / 100Gbps as 25GBaud)  Leverages on Coherent Detection and Electronic Post-Processing to provide high tolerance to PMD and CDDQPSK: Differential QPSK  Differential operating mode provides required system robustness against Laser Cycle Slips  Laser Cycle Slips can be caused by ASE, Laser Phase Noise and XPM (induced by 10G IM/DD channels)  Even w/o 10G channels ASE and Laser Phase Noise can cause Laser Cycle Slips© 2010 Cisco and/or its affiliates.

Direct Detection Must correct for impairments in the physical domain (insert DCU’s) Forced to live with non-correctable impairments via network design (limit distance, regenerate, adjust channel spacing) DCU DCU DCU DD DD Regen Coherent Detection Moves impairment correction from the optical domain into the digital domain Allows for digital correction of impairments (powerful DSP) vs. physical correction of impairments (DCU’s).
