CASE STUDY OF OPTICAL FIBER LOSS AND POWER

By niveksuhail
CASE STUDY OF OPTICAL FIBER LOSS AND POWER ANALYSIS WITH THE LINK BUDGET METHOD IN THE STO AHMAD YANI OPTICAL FIBER NETWORK
This study analyzes the losses of optical fiber to optical fiber communication systems at PT. Telkom ARNET 1 East Bandung, using multimode fiber optic cable type G 655 C and G 652 D. Based on the measurement results using OTDR, the maximum total loss that exceeds the standardization of 0.5 dB / km, occurs in the Ahmad Yani-Tegalega segment, 24 core cable with fiber number 1,2,5,6,7,9,11 and Ahmad Yani-Tegalega segment, 48 core cable with fiber number 35,37,38. Section Ahmad Yani-Dago total lossthe maximum that exceeds the standardization of 0.5 dB / km is the fiber number 18. The minimum standard acceptability is - 4 dBm for laser light sources. From the measurement results, the minimum received power for the Ahmad Yani-Lembong segment is 1.4 dBm, Ahmad Yani Tegalega - 2,893 dBm, Ahmad Yani-Ujungberung 0,932 dBm, Ahmad Yani-Turangga 1,4 dBm, and Ahmad Yani-Rancaekek -0,702 dBm.

ABSTRACT
fiber splicing contractor jobs

This reseach analyzing loss optical fiber to the optical fiber communication systems in PT. Telkom Arnet 1 Bandung Timur, using the multimode optical fiber cables, type G 655 C and G 652 D. Based OTDR measurement results, it was obtained the total loss exceeded the maximum standarization of 0.5 dB/ km that occurred on a segment Ahmad Yani-Tegalega, 24 core cable with fiber numbers 1,2,5,6,7,9,11. The segment of Ahmad Yani-Tegalega, 48 core cable with fiber numbers 35,37,38 and Ahmad Yani-Dago total loss exceeded the maximum standarization of 0.5 dB/km was the number of fiber 18. The minimum received power standarization was - 4 dBm for the laser light source. The obtained measurement results for the minimum received power segment Ahmad Yani-Lembong, Ahmad Yani-Tegalega, Ahmad Yani-Ujungberung, Ahmad Yani-Turangga and Ahmad Yani - Rancaekek were 1.4 dBm, -2.893 dBm, 0.932 dBm, 1.4 dBm and -0.702 dBm respectively.

What Are Backlinks?

By
    Backlinks (also known as “inbound links”, “incoming links” or “one way links”) are links from one website to a page on another website. Google and other major search engines consider backlinks “votes” for a specific page. Pages with a high number of backlinks tend to have high organic search engine rankings. https://plus.google.com/url?q=https%3A%2F%2Fhoneywebsolutions.com%2F https://plus.google.com/url?q=https%3A%2F%2Fwww.honeywebsolutions.com%2F https://plus.google.com/url?q=http%3A%2F%2Fhoneywebsolutions.com%2F https://www.google.com/url?q=https%3A%2F%2Fhoneywebsolutions.com%2F https://www.google.com/url?sa=t&url=http%3A%2F%2Fhoneywebsolutions.com https://www.google.com/url?sa=t&url=https%3A%2F%2Fhoneywebsolutions.com%2F https://maps.google.com/url?q=https%3A%2F%2Fhoneywebsolutions.com%2F https://maps.google.com/url?sa=t&url=http%3A%2F%2Fhoneywebsolutions.com https://images.google.de/url?q=https%3A%2F%2Fhoneywebsolutions.com%2F https://maps.google.de/url?q=h...

One strand of optical fiber is about the diameter of a human hair

By niveksuhail
As the saying goes, one strand of optical fiber is about the diameter of a human hair.CORNING It’s an amazing idea. Now, copper wires—sometimes called “twisted pair” because they are made of pairs of strands of copper twisted around one another—also carry data and telephone signals to homes and farms in much of rural America. But because of the characteristics of copper as a transmission medium, signals that travel over copper doesn’t have the extraordinary frequency range that light signals do, are subject to interference from other signals, and in general, degrade very quickly over more than a short distance. That’s why if you have a copper-wire DSL (digital subscriber line) subscription, you have to be very close to the phone company’s “central office” to get a download signal into your house. A DSL house is connected to a copper wire, not a fiber-optic cable. fiber optic installer salary Not only can light travel over fiber for hundreds of miles with little attenuation (im...

Fiber Optic Light Source

By niveksuhail
Fiber optic light source is a fiber optic test equipment to measure the fiber optic loss for both single mode fiber cable and multimode fiber cables; usually the fiber optic light source is used with the fiber optic power meters. This fiber optical light source can provide wavelength output according to the specific requirements including the 650nm red source, 1310nm/1550nm wavelength for the single mode fiber and 850nm/1300nm wavelength for the multimode fiber. Used together with our fiber optic power meter, they act as an economic and efficient solution for the fiber optic network works. fiber optic light source Fiber Optic Light Source Catalogue in PDFpdf catalogue (76.2KB) This fiber optic light source features compact size and decent appearance, it is small size and light in weight, with high stable output power, large LCD display window and easy operation. fiber optic installation jobs Wavelengths (nm) 650 1310/1550 850/1300 (more wavelengths can be optional; the maximum...
