8 Channel AES/EBU Broadcast Audio Fiber Mux

View : 233
Type : audio fiber mux
Description :

8-channel comprehensive AES/EBU audio optical transceiver adopts digital code technology


    8-channel comprehensive AES/EBU audio optical transceiver adopts digital code technology, which of audio interface is balanced XLR interface, can realize bidirectional long-distance transmission of 8 channels of digital audio signal by one single-mode optical fiber,and the maximum transmission distance is up to 120km.


    Audio optical fiber transceivers are consist of optical transmitter and optical receive, which can be assigned 4 bidirectional or 8 unidirectional audio.


●  Full-digital optical fiber transmission platform, flexible configuration of multiple services on the same platform

●  19 inch 1Ualuminum alloy anodized shell, IP40 protection grade;

●  Use FPGA, digital decode and clock recovery technology, high integrated and high stability.

●  The audio interface is XLR balanced interface, the audio power supply is large-power Toroidal Transformer +-18V power supply, high dynamic range

●  The three standard sampling frequency are 32kHz,1kHz,48kHz, can be supported simultaneously;

●  The audio interface provide 3-level anti-lightning function,can pass the test of ITU-T K.21(10/700 μS),common mode :6KV,impedance(40 Ω)

●  single fiber transmission ,the dual fiber is optional

●  Various power supply ways are optional: AC220V、DC-48V/DC24V etc. And support dual power way :AC+AC,AC+DC,DC+DC


● AES Audio Interface

input&output interface: XLR

input&output impedance: balanced 0dBm/110Ω 

Sampling frequency: 48KHz, 44.1KHZ, 32KHz

Signal level: 2-7V(pp) 

AES transmission distance: 250m


● Optical                              

Wavelength: 1310nm、1550nm

Optical fiber: SM 9/125um

Optical interface: FC 、SC、ST

The distance optical fiber travels is limited by the loss of the optical path and additional losses due to connecting terminals, splices, and patch panels. Transmission distance may also be limited by fiber bandwidth.


● Electric and machine character

Voltage: AC165V ~ 265V;DC –48V;DC +24V

Power consumption: ≤10W


● Environmental indicator       

Working temperature: -10℃—+70℃

Storage temperature: -40℃—+85℃

Working humidity: 0%—95%(no condensation)

MTBF: >100,000 hours
