Characteristics of PM Fiber Patch Cords

 If the polarization of the input light is not aligned with the stress direction in the fiber, the output light will vary between linear and circular polarization (and generally will be elliptically polarized). And the exact polarization will also be sensitive to variations in temperature and stress in the fiber. [ Continue reading…]

WHAT IS OPTICAL CIRCULATOR AND ITS APPLICATIONS?

 An optical circulator is a multi-port (minimum three ports) nonreciprocal passive component.   The function of an optical circulator is similar to that of a microwave circulator—to transmit a lightwave from one port to the next sequential port with a maximum intensity, but at the same time to block any [ Continue reading…]

What is the real difference between CAT6 and CAT6A?

The history of data communications The history of data communications is closely linked to the developments in cabling and the connecting hardware. High-performance data networks and local area networks (LANs) cannot perform well without appropriate cables and connectors. When we take a look at high-speed data networks like Gigabit and [ Continue reading…]

5 THINGS TO KNOW BEFORE WORKING WITH MULTI-FIBER MPO CONNECTORS

  Fiber technicians are constantly challenged to keep up with new, innovative technologies that can disrupt normal long-standing test and certification practices. Whether you are an installation contractor, an IT manager, or somewhere in between, understanding the key concepts and practices of any new technology (such as MPO) is critical [ Continue reading…]

Why A Good Fiber Optic Cleaver Helps Cut Out Costly Mistakes?

  What Is Fiber Optic Cleaver? A cleave in an optical fiber is a deliberate, controlled break, intended to create a perfectly flat end face, perpendicular to the longitudinal axis of the fiber. A fiber optic cleaver is a tool that holds the fiber under low tension, scores the surface [ Continue reading…]

What you should know before buy fiber polishing machine?

  THE POLISHING MACHINE   When it is time to purchase a mechanical polishing machine there are a number of questions that should be asked:   1. Are the operating functions simple to use? 2. Does the unit offer easy connector interchangeability? 3. Are the polishing platens easy to access? [ Continue reading…]

How effective is Polarization Maintaining (PM) Isolator?

Polarization Maintaining Isolator is also known as Fiber Optic Isolator which allows light to travel only in one direction. For any state of polarization, it minimizes the back reflection and back scattering in the reverse direction. It is a two port micro-optic device built with PM panda fiber. Polarization Maintaining [ Continue reading…]

How Do Different Fiber Optic Couplers Work?

What Is Fiber Optic Coupler? Fiber optic coupler is one type of fiber optic component that allows for the redistribution of optical signals. It covers a wide range of fiber optic devices such as optical splitters, optical combiners, and optical couplers. A fiber optic coupler is a device that can [ Continue reading…]

What Is Fiber Optic Pigtail and How to Splice It?

  In fiber optic cable installation, how cables are attached to the system is vital to the success of network. If done properly, optical signals would pass through the link with low attenuation and little return loss. Fiber optic pigtail offers an optimal way to joint optical fiber, which is [ Continue reading…]
