How to choose an optical attenuator. First, I want to check my application. This attenuator where and how to use it for? You must consider the factors in the test lab, I need a different attenuation, in my experiment? Variable attenuator,In most cases you will end up needed to use a Fiber Optic Attenuator and then will be a good choice. You must also consider the type and mode of the fiber. You must also decide what you need, the end result.
We use the attenuator is the path of the attenuation of light along glass or plastic fiber optic cable. The cable is often the jacket, in order to protect the fragile material. The sheath is often Kevlar, to add strength, but the decay does not require sheath or aramid, because of the small molded housing. The molded housing is usually made of metal or plastic.
Fixed optical attenuator – the use of the case, you know, you need the dB value of attenuation.
For example, you may need to reduce by 5dB of optical signals, so you will get a 5 dB attenuation. You should see your connection, so you can order the correct type of fiber-optic attenuator. On the site, if you choose to select your attenuation certainly, and select the appropriate connector type site should contain the type of information on the connector and the decibel value. The connector type is very typical of the Legislative Council LC / APC, SC / UPC, SC / APC / UPC bar code, Mu, FCs, FC / APC and ST.
Like some websites britecom.net – just Google,he GE In-line Coupler easily adds a telephone at a different location without installing a new jack. Great for connecting 2 line cords to create a longer cord they say, good quality and reasonable price. They also said that good customer service. All you have to decide what is the best place to find your fiber optical attenuator, of course, is your choice. We have a free and great to know.
