Extend DisplayPort 1.2 and USB KM device signals up to 300m
KVM Extenders are devices which allow users to work on a computer from a distance by extending the connection between a computer and keyboard, monitor and mouse.
The Fibre Optic DisplayPort 1.2 KVM Extender is an effective, reliable solution for extending high quality 4K DisplayPort signals over distances up to 300m with standard LC fibre cable. Support for DisplayPort 1.2 allows for the transmission of highly detailed 3840x2160@60Hz resolutions, perfect for eye catching digital signage or detailed content in medical setups.
This extender also supports lossless audio formats including Dolby TrueHD and DTS-HD to add powerful multi-channel sound to video content, providing an enhanced experience and sense of immersion for the viewer. USB KM connectivity via 3 USB HID ports allow for a keyboard and mouse at the receiver to control a DP equipped PC from a remote PC setup, which can be stored in a secure or controlled temperature environment, while seamlessly providing consistent video content from the display. The use of LC fibre between the transmitter and receiver provides a reliable, lower cost connection for much longer distances that what is possible over copper cabling, great for use in electronically _noisy_ environments such as factory shop floors or medical installations.
With the ability to extend signals up to 300m using the two included units, the transmitter can be easily connected to a variety of DisplayPort source devices such as PCs and laptops in a more convenient location, while the receiver can be placed in a suitable viewing area with a LFD (large format display), monitor or projector, ensuring there is no distraction from the display from bulky source devices. This versatility provides a suitable system for use in various scenarios such as educational presentations, CAD facilities or remote server administration.
The extenders built-in EDID function ensures maximum compatibility with the display or projector at the receiver, further enhancing this system focus on providing high quality 4K DP content over distances easily and with minimum hassle for the user.
Please note: Lindy_s 10GBase-LR/LW SFP+ LC Single Mode (25039) Fibre Modules can be used as an alternative to the Included Mini GBIC multi-mode LC modules, increasing the maximum range of the extender to 500m (1640.4ft).

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.
