Extend 4K@60Hz resolutions to 4 included receivers
The Lindy 70m Cat.6 4 Port HDMI® 4K60 Splitter Extender is a simple, professional solution for distribution of 4K HDMI® signals to multiple displays using standard Cat.6 network cables.
Scalable Content Distribution
This Cat.6 splitter allows for distribution to up 4 remote locations using the included receivers, at up to 70m in distance, ideal for sharing content simultaneously in sports bars or events. The local HDMI® output on the splitter allows for monitoring using a connected display, or alternatively can be combined with up to 2 additional Cat.6 splitters for even larger scale content distribution.
Immersive 4K and HDR Support
With support for resolutions up to 3840x2160@60Hz, this splitter ensures superior clarity of high-quality video, including movies, sports, games, or live monitoring. HDR support ensures a much wider colour gamut is visualised, alongside a higher peak brightness and deeper blacks for an enhanced dynamic contrast. This provides an eye-catching and engaging experience for the viewer in a variety of different applications including digital signage in retail, content delivery in lecture halls, or information broadcasting in travel hubs.
Seamless IR Control
The included IR cables allow for simple control via an IR remote from any of the receiver locations, removing the need to be situated at the source side on the setup.
Simultaneous PoC Distribution
The Cat.6 HDMI® 4K60 Splitter also support PoC (Power over cable) allowing for power to be distributed alongside audio and video over the cat.6 cabling. This allows for only one power source being required at the transmitter side, ensuring a minimalist and time-saving setup at the receiver locations.
Please Note: The quoted resolutions are possible with a direct connection between transmitter and receiver using good quality Cat.6 solid core cable. Using a different cable type, introducing wall plates, couplers or patch panels will result in a reduction of maximum distances.

Protect Critical SFP Ports from Tampering, Damage or Unauthorised Access
The Lindy SFP Port Blocker provides a fast, effective way to physically secure unused SFP (Small Form-factor Pluggable) network ports. These compact blockers are ideal for safeguarding fibre infrastructure in sensitive IT environments, AV-over-IP setups, and networked installations where access control is essential.
By preventing unauthorised connections, accidental cable insertions or foreign object intrusion, Lindy SFP Port Blockers reduce the risk of port damage and potential downtime. A robust insertion mechanism keeps each blocker firmly in place, with colour-coded keys ensuring only authorised removal. Additional keys and blocker packs are also available.
