KY-727 series are an advanced fiber optical multiplexer/modem products. A fiber optical multiplexer can provide up to 4E1 signals transmission through the fiber optical link. It is a very flexible and efficient way to use the KY-727 in your fiber optical transmission network; such as PSTN, SONET/SDH, LAN, B-ISDN, ATM, Internet and DLC. It has various network application such as voice, data, video and wireless. It is very easy to operate and monitor the local and remote system by some switches and LED.
The KY-727 series Provides two fiber links for 1+1 protection and make automatic protection switch. The E1 electrical interfaces meet the ITU-T requirements. The KY-727 also provides the local and remote loopbacks of optical interface and each E1 for maintenance. Of course, it also has alarm function.
