Triplexer was one of the key components in FTTH systems, which employed an analog
overlay channel for video broadcasting in addition to bidirectional digital transmission. To …

With rapid development of Internet and broadband access network, the technologies of
xDSL, FTTx+ LAN, WLAN have more applications, new network service emerges in endless …

In order to detect the defects of TFT LCD screens automatically, an optical system based on
multi-camera imaging was established. The structure of TFT-LCD module and the causes of …

In this paper, the mechanism of failure (breakdown) detection in an optical fiber line will be
studied. The objectives of this paper are to understand in detail the mechanism of faulty fiber …

In this paper, we analyzed and measured the electrical crosstalk characteristics of a 1.25
Gbps triplexer module for Ethernet passive optical networks to realize fiber‐to‐the‐home …

A new technique for detecting any faulty fiber and identifying the failure location occurring in
tree-based structured fiber-to-the-home (FTTH) access network with centralized failure …

We proposed and developed a fully passive device prototype, named Passive In-line
Monitoring (PIM) device, which used to tap out a small ratio of triple-play (data, voice, and …

The FTTH business needs new network maintenance technologies that can, economically
and effectively, cope with the massive FTTH fiber plants that are yet to come. Based on the …

Aiming at the characteristics of the self-designed and developed Fiber Tree Bus (FTB)
terminal, such as more terminals, more interactive data and various node communication …

To plan a rapid response and minimize operational costs, passive optical network operators
require to automatically detect and identify faults that may occur in the optical distribution …
