No Audio Device

Posted by 8 March, 2018 (0) Comment

The no audio device message normally appears on your computer screen when you have no audio device installed. The computer is unable to play any sounds unless it has an internal speaker then you might hear a bleeping sound. If you have connected a speaker and it still displays the message it may be because there are no drivers installed in the computer to support the hardware.

If you are using a Windows Media Player you will receive several error messages. To get rid of the sign you will have to trouble shoot checking that all the requirements are installed properly including the drivers.

In case the sign persists, there is a problem with the device and you need to return it to the vendor.

Posted by 8 March, 2018 (1) Comment

MTRJ is an abbreviation of Mechanical Transfer Registered Jack and refers to a connector used in fiber optic cables. This connector is small in size and this has made it very popular among users who have small form factor devices. It houses two fibers and joins locating pins that are found on the plug and can have about 12 fibers.

It is one of the recent connectors that are currently being used. It uses two fibers and which are incorporated into one design that is similar to the one used by the RJ45 connector. The alignment is done through the two pins that are connected to this connector. Unlike the single fiber connectors, the MTRJ has lower termination costs and more density for the cable management and electronics hardware.
