Conclusions

Setup Description

Simultaneous transmission of wireless and wireline

signals over the same optical fiber access platform

Results

•Single reconfigurable DSP enabled

coherent

receiver

supporting

heterogeneous wireless/wireline next

generation metro-access networks

•Experimental

demonstration

of

simultaneous transmission of different

types of services over deployed fiber link

•Experimental demonstration automatic

recognition of modulation formats

• Mixed modulation formats, baseband and

Radio-over-Fiber, supporting wireline and wireless services:

• Baseband 5 Gbps Intensity-Modulated VCSEL

• Baseband 20 Gbps NRZ-DQPSK

• Radio-over-Fiber 2 Gbps phase-modulated IR-UWB

• Radio-over-Fiber 5 GHz 4-QAM OFDM

• Single reconfigurable digital coherent receiver

• Linear signal demodulation

• Frequency offset compensation

• Digital phase-locked loop (DPLL)

• Digital dispersion compensation

Wired and Wireless Service Convergence in Access Network

• Next generation networks need to support diverse

broadband services

• Need

for

re-configurability

and

accomodation

of

bandwidth requirements
