Optical Fiber Bending Loss
2007-04-20 07:13:00
Optical fibers suffer from micro-bending loss at bends or curves on their paths. This is due to the energy in the evanescent field at the bend exceeding the velocity of light in the cladding and hence the guidance mechanism is inhibited, which causes light energy to be radiated from the fiber. This is shown in the ...

How do I calculate fiber optic link budget?
2007-04-13 07:47:00
In order to accurately calculate fiber optic link budget, you should know two concepts: installation loss and AC losses. What are installation losses? Installation loss is also called DC loss. It refers to optical losses caused by fiber optic cabling plant. This includes fiber transmission loss, attenuation versus wavelength and connector and splicing loss. Transmission Loss Transmission loss is ...

Advantages of VCSEL Lasers
2007-04-10 06:54:00
VCSEL lasers have the economic advantage over any other diode lasers. This short explanation tells you why. A typical VCSEL consists of two oppositely-doped Distributed Bragg Reflectors (DBR) with a cavity layer between. In the center of the cavity layer resides an active region, consisting of multiple quantum wells. Current is injected into the active region ...

How do I make a perfect fusion splice?
2007-04-04 07:02:00
Fusion splice process is to literally weld two prepared fiber ends together, thereby creating a permanent joint with the minimum possible insertion loss. The fusion splice process is illustrated as follows. So what factors in the fusion splice process determine the insertion loss achieved? The loss mechanism in fusion splice joint may be summarized as follows: Core ...

Types of Fibers
2007-03-30 06:57:00
Glass Fiber Glass fiber is the most common type of fiber available, with companies such as Corning and Siecor producing billions of meters per year. Common industry-standard glass fibers are differentiated by the diameter of the core: larger cores allow more modes to propagate; smaller cores allow fewer. Glass fiber is available in three common sizes: ...

Is multimode fiber a better choice than single mode fiber?
2007-03-19 22:57:00
Well, the short answer is YES for premises and local area networks. Sing le mode and multimode fibers have different network applications, because they have very different optical-performance attributes. In the design of premises and local area networks the decisive factor is the overall cost of all components. The large core of multimode fibers (50um or 62.5um) has distinct advantages: ...
