HOW DOES AN OTDR WORK?
No Commentsby Fiber-MART.COM Unlike sources and power meters, which measure the loss of the fibre optic cable plant directly, the OTDR works indirectly. The source and meter duplicate the transmitter and receiver of the fibre optic transmission link, so the measurement correlates well with actual system loss. The OTDR, however, uses [ Continue reading…]
What Is OTDR Testing?
No Commentsby Fiber-MART.COM In many of my previous articles on fiber optic testing, I have mentioned optical time-domain reflectometers (OTDRs). OTDRs are valuable fiber optic testers when used properly. Improper use, however, can be misleading and, in my experience, can contribute to expensive mistakes for the contractor. I have been personally [ Continue reading…]
Using an OTDR: How to keep it simple
No Commentsby Fiber-MART.COM Communications networks never go slower, never get simpler, and never stay the same. Likewise, certification testing for fiber-optic cabling has also changed. New test equipment and enhanced testing regiments help ensure that cabling can support the new demands placed on networks. Born from legacy test equipment for [ Continue reading…]
Why Needs Cisco GLC-LH-SM Transceiver
No Commentsby Fiber-MART.COM Fiber optic technology has proven itself as an indispensable component for network backbone and other high-demand applications as it generally offers greater bandwidth than traditional copper cable. However, fiber optic cables are made of a specialized glass-like material that costs more to manufacture than traditional copper networking cables. [ Continue reading…]

Fiber Optic Cable and Connector Selection
No Commentsby Fiber-MART.COM Proper selection of fiber optic cables and connectors for specific uses is becoming more and more important as fiber optic systems become the transmission medium for communications and aircraft applications, and even antenna links. Choices must be made in selecting fiber optic cables and connectors for high-reliability applications. This article [ Continue reading…]
Is Fibre Optic good for network speed only?
No Commentsby Fiber-MART.COM Higher Bandwidth – longer range, better network speed Fibre optic cables are made of glass threads which transmit data at the speed of light in glass (around 180,000 to 200,000 km/s…!). Because the speed of light is the fastest speed known, data is transmitted faster than via copper wires [ Continue reading…]
What Makes Optical Fibre Immune To EMI?
No Commentsby Fiber-MART.COM Optical Fibre Is Immune To EMI Fibre optic cables are non-metallic… they transmit signals using pulses of light in glass threads! As a result, they are immune to Electro-Magnetic Interference and Radio Frequency Interference. In other terms, the integrity of signals is not affected by electrical noise in the [ Continue reading…]
Everything You Need to Know About Fiber Optics Cable
No Commentsby Fiber-MART.COM In the recent years, fiber optics is steadily replacing copper wires. It is a better and apt means of transmitting communication signals. Today, fiber optics cable span across long distances between local phone systems. In addition, it also serves as the backbone for many networking systems including: [ Continue reading…]
