40 km HDMI fibre extender

This Lenkeng LKV378A-V4.0 transmits 1080p@60Hz video up to 40 km over single-mode fibre. The transmitter includes an HDMI loop-out for local monitoring and the system supports IR passback for remote control. It is built for professional AV installations such as security monitoring, medical imaging and commercial displays.

Installers needing long-range 1080p distribution

The extender suits integrators who must bridge tens of kilometres with a single fibre strand and a bidirectional SFP module. Buyers who require 4K resolution, HDR metadata or multicast distribution over IP networks should look elsewhere.

40 km single-mode fibre reach

The decisive specification is the 40 km transmission distance over single-mode fibre using the supplied SFP-GE-BIDI module. If the installation path is shorter or multimode fibre is already in place, a different extender will be more appropriate.

Questions about this item

What type of fiber and connector does the 40km link require?

The extender uses a single-mode SFP module with LC connectors operating at 1550nm transmit and 1310nm receive wavelengths.

Which power supply must be used for the transmitter and receiver units?

Each unit needs a DC 5V adapter; verify any third-party supply matches this voltage exactly before connecting.

Is the optical SFP module a part that may need replacement over time?

The SFP transceiver is a field-replaceable component; keep a spare 1.25G single-mode module on hand for quick swap if the link degrades.
