AV vysielač a prijímač ATEN VE883AK1 True 4K HDMI optický extender 4K@300m 10km

The ATEN VE883A is a True 4K HDMI optical extender kit composed of a transmitter (VE883AT) and a receiver (VE883AR) designed to transmit uncompressed HDMI video up to 4096 x 2160 / 3840 x 2160 at 60 Hz (4:4:4) together with audio, USB 2.0, IR, RS-232 and Gigabit Ethernet over a single duplex fiber optic cable. Available in configurations for multimode 300 m (VE883AK1) or single‑mode 10 km (VE883AK2), the VE883A provides electrical isolation through fiber cabling, preventing RFI and EMI interference while reducing bulky copper cable runs. ATEN’s FarSmooth technology matches output and input rates to prevent lagging and freezing, ensuring stable, smooth video that remains identical to the source for long‑distance extension scenarios.

Advantages

The VE883A transmits True 4K HDMI with 4:4:4 chroma, preserves audio and multiple control channels (USB 2.0, IR, RS-232, Gigabit Ethernet) over a single fiber link, and offers two distance options (300 m multimode or 10 km single‑mode). Fiber connectivity delivers electrical isolation to eliminate ground loops and electromagnetic interference. Dual USB Type‑A ports on the units expand peripheral connectivity, and included pluggable SFP+ modules simplify optical setup. The extender is also compatible with ATEN VM7584 / VM8584 optical I/O boards for integration into modular matrix systems.

Suitable for

• Control rooms and command centers requiring long‑distance, high‑quality video
• Industrial environments and factories where electrical isolation is needed
• Medical and hospital installations demanding reliable True 4K transmission
• Professional AV systems and modular matrix switch integrations

How to use

Connect the VE883AT transmitter to the HDMI source and required control ports (USB devices, IR emitter, RS‑232, Ethernet) and connect the VE883AR receiver to the display and corresponding control endpoints. Insert the provided SFP+ optical modules into the SFP+ ports on both units and link them with the appropriate duplex fiber optic cable (multimode for 300 m VE883AK1 or single‑mode for 10 km VE883AK2). Power both units with the supplied 5 V adapters. The system automatically negotiates video and control signals; adjust source and display settings as needed for optimal 4K output.

Recommendations

Use high‑quality duplex fiber and properly rated SFP+ modules that match the kit version (multimode for VE883AK1, single‑mode for VE883AK2). Ensure both transmitter and receiver have stable 5 V power and check cable terminations and polarity. For USB peripherals requiring higher power, verify device compatibility with USB 2.0 limitations. In electrically noisy environments, rely on the fiber link to maintain signal integrity and avoid running additional copper cables in parallel with power lines.
