This work addresses security risks in a gigabit passive optical network. The completely
passive infrastructure enables active monitoring of the distribution network in parallel with …

The newly proposed digital-signal-processing (DSP)-enabled reconfigurable optical
add/drop multiplexer (ROADM) without incorporating optical–electrical–optical conversions …

With the rapid growth of new broadband services and traffic flows, Passive Optical Network
(PON) is facing the challenge of bandwidth crunch and energy consumption. There are a …

The convergence of multiple service demands and different user types on a single physical
layer can be enabled by dynamically reconfigurable time-division multiplexing (TDM) dense …

摘要宽带通信网包括高速光纤传输骨干网和宽带接入网(BAN), 但两者发展极不平衡.
尤其是BAN 在保密性与私有性, 成本与能耗, 融合兼容性及速率与带宽等方面亟待突破 …

This paper proposes a Hadoop system that considers both slave server's processing
capacity and network delay for wide area networks to reduce the job processing time. The …

Nowadays, the Internet plays a vital role in our lives. It is currently one of the most effective
media that is shifting to reach into all areas in today's society. While we move into the next …

The integration of Software Defined Networking (SDN) technologies in Passive Optical
Networks (PONs) would provide great advantages to Internet Service Providers (ISPs) and …

Newly proposed DSP-enabled ROADMs free from O− E− O conversions offer an excellent
opportunity of utilising advanced DSP techniques to greatly simplify complicated …

Utilizing Hilbert-pair-based digital filtering, intensity modulation and passive optical
coupling, DSP-enabled optical filter-and OEO conversion-free ROADMs have been reported …
