  • Extends HDMI 2.0 18G signals up to 300m over a simplex LC multimode cable or up to 1000m over a simplex LC singlemode cable
  • Supports resolutions up to  4K 60Hz Ultra HD, with High Dynamic Range
  • Bi-directional IR or RS-232 for seamless, flexible control
  • HDCP 2.2 support to ensure maximum compatibility
  • 2 year warranty

The Lindy 300m/1000m Fibre Optic HDMI & IR Extender is a high performance solution for extending 4K 60Hz Ultra HD transmissions over incredible distances, which are not possible with traditional copper based systems, using a single standard LC simplex fibre optic cable.

Support for the HDMI 2.0 specification allows for the transmission of highly detailed 4K Ultra HD resolutions, using smart methods of compression, which decompresses the signal at the receiver for a visually lossless picture. Also providing support for High-Dynamic Range, video content can be seen with enhanced brightness, greater contrasts and a much wider colour gamut, perfect for creating eye-catching digital signage in retail, impressive residential installations or taking sports venue distribution to new immersive levels. HDCP 2.2 compatibility also means that protected 4K content including movies and TV shows can be viewed without issue. 

As opposed to the use of copper based extension systems, the use of fibre optic cable also ensures immunity to RF and EMI, providing a stable signal in ‘noisy’ retail or industrial environments which can have a high interference from electronics. 

With the ability to extend signals up to 1000m the extender provides huge installation flexibility, the transmitter can be easily connected to a variety of HDMI source devices such as Blu-Ray players, 4K HDR media players or PC's in a convenient location, while the receiver can be placed in a suitable viewing area along with a 4K display or projector. The included mounting brackets also allow for a neat installation under desks or discreetly hidden behind displays.  

Featuring bi-directional IR and RS-232 ports, the extender provides the capability for source equipment to be seamlessly controlled from the display side, and the display can also be controlled from the HDMI source device, great for providing simple, flexible control over the installation for the user. The support for RS-232 enables the extension of control signals as part of a larger installation.

The HDMI fibre extender you want for 4k

Most importantly you want this unit because the vast majority of HDMI extenders do not support full HDR (4:4:4) as this requires more than 10Gbps bandwidth, and AFAIK Netflix for example ONLY supports full HDR for 4k video playback!

They have the ability to use standard (cheap and available in most lengths) duplex LC-LC fibre optic patch cables, or even patch one of these into a one ultra-compact MTP breakout cable for 6 or 12 full duplex links in a single cable; and bog standard SFP+ (10Gbps, pretty cheap) optics, with multimode SR optics from FS.com supplied, but you can use singlemode LR optics for up to 10km of fibre between units!
Although the optics only work at 10Gbps for Ethernet, these boxes use a clever encoding scheme (like digital Satellite signals) that enables more than 10Gbps bandwidth with the same optics.

Unlike cables with integrated optics that can overheat, get damaged where the cable joins the optic, or damage the socket in your expensive equipment due to the weight of the cable or someone tripping on it, these units come with screw-down brackets, IR extenders and mains-noise-tolerant switch-mode international wall-wart type 12V DC PSUs in the box!

I have not tested the 4k capability, but these are flawless for 1080p, and eliminate ground loop issues or the signal degradation that usually occurs when you daisy-chain HDMI cables, which is a violation of the HDMI standard by the way (loss of sharpness, snow, momentary loss of sync, colour infidelity etc). The HDCP support worked fine with my Gen 1 HDTV.

A premium solution yes, but the combination of a rock-solid reliable design, ability to replace optics or cables if damaged, 100% elimination of interference, grounding, mains power noise and termination-related problems make this a very good bet for a sound and trouble-free investment that betters active cables.
