Extend HDMI® resolutions up to 70m via HDBaseT
The Lindy 70m Cat.6 HDMI® & IR HDBaseT Extender with PoC is an end to end solution for extending HDMI signals over long distances via Cat.6 network cable.
The following distance and resolution combinations are possible when using high quality Cat.6 U/UTP or F/UTP cable:
70m: 1920x1080@60Hz 4:4:4 8bit
40m: 3840x2160@30Hz 4:4:4 8bit
Supporting resolutions up to 4K Ultra HD, video can be viewed in stunning clarity, providing a reliable solution for creating eye-catching digital signage in retail, immersive displays at events or engaging setups in larger conference rooms or lectures halls.
PoC (Power over Cable) functionality provides additional flexibility. This allows power to be supplied alongside data through Cat.6 network cable in a point to point connection between the transmitter and receiver, meaning only a single power supply is required at the transmitter unit. Ideal when power outlets are limited at the receiver end of the installation.
Featuring bi-directional IR ports at both sides of the setup, the source equipment can be easily controlled from the display side, and the display can also be controlled from the HDMI® source side. Combined with CEC control, which allows commands from one main remote, this extension system allows for complete and simple control for the user. RS-232 pass-through also allows for integration into larger control systems.
In addition, the power supply is connected via a screw type DC jack, providing a more secure and reliable connection, perfect for professional installations where accidental disconnections could create a major issue.
HDBaset is a globally recognised standard for high quality distribution of AV content and other technologies, including power and control, over longer distances via low cost Cat.6 or above cable.

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.
