AV transmitter LevelOne 4-Channel BNC over Fiber Optic Extender Kit 20km

The LevelOne AV transmitter 4-Channel BNC over Fiber Optic Extender Kit 20km (AVF-1401) transmits analogue composite video signals over optical fibre for distances up to 20 km. Video signals are digitized at the transmitter, converted to optical signals and sent over the fibre link to the receiver, which converts them back to analogue for display on monitors. The compact unit (116.5 x 48 x 157.1 mm, 1.38 kg) supports fibre wavelengths 1470–1610 nm and 1310 nm and is powered by 5 V (3 A input), making it suitable for extending analogue surveillance, signage and video wall systems while integrating with existing BNC infrastructures.

Advantages

This kit enables long-distance, low-loss transmission of analogue video using optical fibre, preserving image quality compared with traditional coaxial links. The transmitter supports four BNC channels, fits standard BNC-based installations and reduces the need to replace existing analogue cameras or displays. Its compact, black enclosure and modest power requirement simplify installation in professional AV and surveillance deployments.

Suitable for

• Analogue CCTV and surveillance systems requiring long-distance transmission
• Digital signage and video wall installations using BNC inputs
• Upgrading legacy analogue AV installations without replacing cameras or monitors

How to use

Connect each analogue composite video source to the transmitter’s BNC inputs. Link the transmitter and receiver with a compatible single-mode fibre cable using the specified wavelength range. Power the unit with a 5 V, 3 A supply. At the receiver end, connect the BNC outputs to monitors or recording devices. Verify signal integrity and adjust cable routing and connectors to maintain clean optical connections.

Recommendations

Install and terminate fibre connections following industry best practices to avoid signal loss. Use single-mode fibre for distances approaching 20 km and ensure compatible transceiver wavelengths. Ground and mount units in dry, ventilated locations and verify power supply compatibility with the 5 V/3 A requirement.
