SC Singlemode UPC Fixed Type 7dB Fiber Optic Attenuator with 1-30dB Attenuate

 

Specification

 

1. Fiber optic attenuator, is a device used to reduce the power level of an optical signal, either in free space or in anoptical fiber.

 

2. The basic types of optical attenuators are fixed, step-wise variable, and continuously variable.

 

Advantages

 

1. Environmentally stable

2. Easy Installation

3. Custom Designed Specifications

4. Low Return Loss

5. Readily Panel Mountable

6. Compact Packaging

 

1. Fixed optical attenuators used in fiber optic systems may use a variety of principles for their functioning.

 

2. Preferred attenuators use either doped fibers, or mis-aligned splices,or total power since both of these are reliable and inexpensive.

 

3. Inline style attenuators are incorporated into patch cables.

 

4.The alternative build outstyle attenuator is a small male-female adapter that can be added onto other cables.

 

5. Non-preferred attenuators often use gap loss or reflective principles. Such devices can be sensitive to: modal distribution, wavelength, contamination, vibration, temperature, damage due to power bursts, may cause back reflections, may cause signal dispersion etc.
