In this paper, we discussed the mechanism of optical fiber break in time division multiplexing passive optical network (TDM-PON) and the upwardly or downwardly monitoring issues with conventional fiber fault localization technique by using optical time domain reflectometer (OTDR). We also studied the previous fault localization technology that had been recommended. Finally, we proposed a centralized inline monitoring and network testing system named as Centralized Failure Detection System (CFDS). CFDS will be installed with optical line terminal (OLT) at
the central office (CO) or network operation center to centrally monitoring each optical fiber line's status and detecting the failure location that occurs in the multi-line drop region of fiber-to-the-home (FTTH) access network downwardly from towards the customer premises to improve the service reliability and reduce the restoration time and maintenance cost.

This research was conducted to develop a 1×12 optical splitter based on polymer optical fiber (POF) made from polymethyl methacrylate (PMMA) material as a high efficiency optical signal transmission medium. Basically, the optical device has 1 POF input port and 12 POF output ports in a bundled fiber form. There are several system available in the market which are able to split or couple optical signals transmitted into some different channels, which are all afflicted with certain constrains. However, these systems are too expensive for most applications. The goal of this research was to develop an economical splitter for multi-purpose application over PMMA-POF. Red LED with 650 nm wavelength was injected into the splitter with the aim to analyze the power efficiency of the splitter. A coupling efficiency of 80% was demonstrated. The performance of these hand-made splitters can be improved gradually through experience and practice.

Optical Communication Systems is a major course which offered in high-speed communication systems
module in communication engineering program. To ensure the qualities of good teaching and learning, some
activities need to be organized such as embedded laboratory in course. In this laboratory students are required
to make a mini-group project to design an optical communication system of the new millennium. This study
reported a plastic-based communication system in which students are involved with the development of its own
components transmitter, receiver and Plastic Optical Fiber (POF) devices. The Network is developed by using
LED sources which modulated with data at different transmission rates. The proposed system can be classified
as Green Technology because the fabrication process of devices (optical splitter) is done without involving
chemicals and gasses. The outcomes of this study enable the students develop their own communication system
using LED POF communication with high capacity, inexpensive and safe, and practice in their daily lives and
with the environmental friendly awareness.

In this paper, a polymer optical fiber (POF) is applied for temperature measuring of water solution using a light source of 650nm. The aim is to analyse the impact of temperature variations on the output of POF sensor device in terms of output power and sensitivity. From the study, the POF sensor shows a linear trend when the temperature is increased from 30°C to 80°C with the sensitivity of the polymer optical fiber for output power to the temperature are 0.00973 dBm/°C or 0.14797 nW/°C, for optical characterization and 0.0011 V/°C for electrical characterization. The integration of the Internet of Things to the system helps the user to monitor the temperature of various spaces anywhere at any time. The sensed values are controlled by Arduino Uno R3 and then sent to Blynk to provide wireless monitoring by the user.

The requirements of bandwidth are increasing very fast in communication systems and therefore the effective solution is to use the Wavelength Division Multiplexing (WDM) technology, whereby several different wavelengths can carry information over one Polymer Optical Fiber (POF). Wavelength Division Multiplexer is an essential component to combine several different wavelengths before all wavelengths are carried together over single POF. In most instances, the conventional multiplexers are afflicted with certain disadvantages and one major disadvantage is that they are costly for most of the POF applications. Thus, the goal of this study is to develop self-fabricated 1x4 POF coupler as an economical optical multiplexer for WDM transmission over POF. The POF coupler has been fabricated by homemade fusion technique. Red LED with a 650 nm wavelength has been injected into the coupler for the purpose of characterization testing to analyze the level of power efficiency of the splitter. The characterization of POF coupler reveals that the maximum power efficiency could be reached up to 90%. The result exhibits that self-fabricated 1x4 POF coupler has great potential to be applied as optical multiplexer for WDM fiber technology due to the character of high-efficiency and low-cost.

Optical Fiber made by plastic or polymer, can be and is being used in various fields of application.
Two of the main fields are the automotive and the home networking. polymer optical fiber (POF) here can be seen
as one of the best solutions for small world communication, especially in home networking application. In this
paper, optical 13 fused-taper-twisted POF splitters has been fabricated by a distinguished technique and proposed
to be applied on small world communication application. There several systems available on the market, which can
be split a coupled signal to be transmitted into some different channels, which are all afflicted with certain
disadvantages. But all these solutions have one main constraint; very expensive for most of the applications as
mentioned above. So the goal of this study is to fabricate an economical splitter for small world communication over
POF. Characterization of the splitter was reported. Reach up until 668 nm wavelengths Light Emitting Diode (LED)
has been injected into the splitter to determine and analyze the level of efficiency of the splitter. Final analysis
shows that efficiency of splitter output able to reach up to 80%. The device performance can be improved gradually
through experience and practice. Main point here is the fabrication process is simple, easy and suitable to be used for
household.

This study presents second generation low-cost fused tapered (LFT) 1 × 3 splitter (G2) as novel, low-cost and low-losssplitting device made from PMMA-based polymer optical fiber (POF). G2 (short taper, 0.5 - 2.0 cm) was fabricated byreformulated handwork fusion method using candle and metal tube. A new process, twisting-effect removal, is addeed to refineripple surface in fused input fiber. LED fiber source (wavelength 650) was injected into input fiber while optical power in outputfibers was measured by optical power meter. Insertion loss (7 dB) and excess loss (0.53 dB) for G2 are extremely low. G2 arehomogenous splitters since their splitting ratio are very close to 33:33:33% with ± 5% of tolerance.

The main idea is to separate the chromatic light in its monochromatic components with the help of a prism with low reciprocal dispersive power. The prism and the other assemblies, which are needed to adjust the optical path, should be manufactured in injection molding technique. This manufacturing technique is a very simple and economical way to produce a mass production applicable Demultiplexer for POF.

The infrastructure that was developed in the village of indigenous people over the utility just like water,
electricity, cooking materials. However, communications with the outside world system is not developed
properly. Telephone, Internet and online entertainment cannot be owned by them. This is due to consideration
of the maintenance work is difficult and cannot be done by the party offering the service. Therefore, this study
proposes a method of development of communication systems can be developed by the user without the use
of complex systems and solutions. This means that the devices and the communication system platform is
developed their own and additionally can be repaired by the users themselves without outside help.
Communications of the proposed green is safe, large capacity data transmission and solutions are
environmentally friendly. Completion of the offer are suitable for facilities in rural population, especially
indigenous people in Malaysia.
