4 PCM Voice Telephone Media Converter Over Fiber with Ethernet

What Is 4 PCM Voice Telephone Media Converter Over Fiber with Ethernet?

Description:

4 PCM Voice Telephone Media Converter Over Fiber with Ethernet The PCM Voice Telephone system over one Fiber Optic S/M up to 20Km (12.4miles) and M/M up to 500m. with one 10/100Mbps Ethernet for network extending, also can use for IP camera with RJ45 connector,SC fiber interface(FC/ST/LC optional). , S/M 40Km/60Km/80Km optional.

A PCM Voice Telephone Media Converter Over Fiber with Ethernet is a device that allows for the transmission of voice signals over fiber optic cables. PCM stands for Pulse Code Modulation, which is a digital representation of analog signals. In the case of telephone signals, PCM is used to convert the analog voice signals into digital signals that can be transmitted over a digital network.

The media converter takes the digital PCM signals and converts them into an optical signal that can be transmitted over a fiber optic cable. At the other end of the fiber optic cable, another media converter converts the optical signal back into a digital PCM signal that can then be decoded and played back as an analog voice signal.

The Ethernet port on the media converter provides a means of connecting the device to a network. This allows for the transmission of the voice signals over an IP network, which can be useful in situations where it is necessary to connect remote locations or where traditional telephone lines are not available.

Overall, a PCM Voice Telephone Media Converter Over Fiber with Ethernet can be a useful tool for transmitting voice signals over long distances or for connecting remote locations. It can also be used in situations where traditional telephone lines are not available or where the cost of installing and maintaining traditional telephone lines is prohibitive.
