8 Channel AES/EBU Broadcast Audio XLR to Fiber Converter

View : 1,253
Type : XLR Audio over Fiber
Description :

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


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


The AES/EBU audio XLR to fiber converter consists of a transmitter and receiver, 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 integration and high stability;

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

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

The audio interface provides a 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. It supports dual power: 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


● Fiber                            

Wavelength: 1310nm; 1550nm

Optical fiber: SM 9/125um

Optical interface: FC, SC, ST

The distance optical fiber travels are 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.


● Power

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
