Technology Consulting

We provide technology consulting service in following two fields:

• Optical Fiber Networks (Optical Layer) Design and Analysis
• Microwave Photonics

Optical Fiber Networks Design

Our expertise includes:

• Theoretical analysis on full range of photonics issues in long haul/metro/access DWDM/CWDM transmission
• Metro DWDM ring networks topology design - protection mechanism (UPSR, BLSR), wavelength reuse, node structure, traffic pattern, dynamic provisioning, etc
• Amplified or passive metro DWDM optical system architecture and optical layer design - power management, signal-to-noise ratio, power budget, amplification schemes, dispersion budget, etc
• 10Gbps transmission - dispersion compensation, non-linear effects, transmitters and receivers, optical fibres, etc.
• System transmission/sub-system/component testing and performance measurement - amplified optical link bit-error rate (BER) test, WDM wide-band EDFA testing and evaluation, DWDM/CWDM component performance tests, etc.

Microwave Photonics

Our expertise includes:

• Phased array antennas, beam forming networks and its applications in radars and RF communications
• Microwave (RF signal) optical signal processing theory and experiments
• Novel Photonics RF signal processing techniques
• RF over optical fibre
• Non-linear effects of the optical fibre and their applications in RF signal processing, including SRS, FWM, etc.
• System transmission/sub-system/component testing and performance measurement - amplified optical link bit-error rate (BER) test, WDM wide-band EDFA testing and evaluation, DWDM/CWDM component performance tests, etc.
• Semiconductor optical amplifiers, wavelength conversion in microwave photonics
