FX-I355 – HDMI 4K ULS Fibre Extender Cable: Secure 4K Signal Extension for Professional AV Installations
The FX-I355 HDMI 4K ULS fibre extender cable integrates a hybrid construction, combining optical fibre for AV signal transmission and copper for power and data pathways. This design supports stable, high-bandwidth HDMI connectivity across extended distances, while the LSZH (Low Smoke Zero Halogen) jacket minimises smoke and toxic emissions in critical environments. The cable incorporates gold-plated precision contacts and the proprietary ULS (Ultra-Lock-System), which provides enhanced mechanical security for fixed installations. Suitable for meeting rooms, control rooms, and digital signage, the FX-I355 supports plug-and-play operation, including CEC, EDID, and HDCP protocols.

  • HDMI 2.0 – 18Gbps Transmission: Supports resolutions up to 4K UltraHD at 60Hz, maintaining full bandwidth for high-definition video and audio. The cable’s hybrid design ensures reliable signal integrity over 5 metres, addressing the demands of modern AV deployments in workspaces and presentation areas.

  • Gold-Plated Precision Contacts: Features 24kt gold-plated contacts with the PureLink ULS (Ultra-Lock-System), which provides a secure and stable connection. This mechanism reduces the risk of accidental disconnection, particularly in fixed or semi-permanent AV installations.

  • HDMI-A Male to HDMI-A Male: Utilises standard HDMI-A male connectors at both ends, enabling direct compatibility with a wide range of professional AV equipment, such as displays, matrix switchers, and source devices commonly found in control rooms and conference setups.

  • Hybrid Fibre and Copper Construction: Employs optical fibre for AV signal transmission and copper conductors for power and data. This configuration supports high-speed data transfer while ensuring power delivery and control signal compatibility, all within a compact 4.5mm outer diameter for flexible routing.

  • Halogen-Free LSZH Jacket: The low smoke zero halogen (LSZH) outer sheath reduces smoke and toxic gas emissions in the event of fire, supporting safety requirements in public buildings, meeting spaces, and critical infrastructure environments.

Reliable 4K Signal Extension for Demanding AV Environments
The FX-I355 serves as a comprehensive solution for extending HDMI 4K signals in professional AV environments, combining hybrid fibre-copper construction with secure ULS locking and LSZH safety compliance. By supporting plug-and-play protocols and maintaining mechanical reliability, this unit provides dependable connectivity for control rooms, signage, and workspace integration.

FiberX - When Distance, Quality and Bandwidth are Essential
The FX-I355 HDMI Premium High Speed with Ethernet cables, included in the FiberX series from PureLink are designed for an optimal transmission of HDMI 2.0 signals over long distances. The hybrid construction of fiber and copper conductors allows significantly longer cable lengths than conventional HDMI copper cables. The AV stream is transmitted via optical fibers, completely free of electromagnetic interference and is supplemented by copper wires for the transmission of power (HDMI 5V) and data (e.g. HPD, CEC). Due to this structure, the cables are available for very long lengths between 5.00 and 100.00 meters and can be used in complex environments.
The cables are compliant with the HDMI standard "HDMI Premium High Speed with Ethernet" for HDMI 2.0 compatible devices and are capable of transmitting AV streams up to 18Gbps. They are capable of resolutions up to 4K / UltraHD with up to 60Hz including the digital audio signal and with support for HDCP up to version 2.2. The transmission is without delay (zero frame delay) and compression, supports ARC and eARC (if supported by the device) as well as transparent EDID.
The cable also features the patented Ultra-Lock-System™. This ULS™ technology has been developed specifically for the uninterrupted and secure use of HDMI connections. The innovative design locks the connector securely into the socket and is unique on the market. The safety lock can be used universally with any HDMI socket and can be easily switched between the locked and unlocked positions by using a 360° locking switch.
The small cable diameter of only 4.5mm allows an extremely tight bend radius up to 45mm (static) or 90mm (dynamic), especially for installation in tight environments, such as the back of a rack.
The HDMI-A ULS™ connectors on both sides feature gold-plated precision contacts and a connector body made of plastic. Thus, the plugs themselves are resistant to corrosion, guaranteeing long-term functional data transmission.
The HDMI AOC cables use the "Plug&Play" principle and can thus be used like a conventional HDMI cable. They are unidirectional, i.e. directionally bound and should not be connected the wrong way round the ends are distinctly marked. Adaptation to other types of signals cannot be guaranteed. The cables are also free of halogens. They therefore produce significantly less smoke in the event of fire than cables, that have been manufactured with halogens.


FiberX Series
The AV industry continues to push for greater bandwidth, faster speeds and a lossless signal quality over ever increasing distances. Traditional copper cabling is becoming less reliable or inadequate for these long ranges. The FiberX product line has long been setting standards as a leading brand for optical fiber solutions. By combining different optical transmission standards with cutting-edge technology, FiberX ensures that existing AV infrastructures continue to meet the highest standards.
In addition, the high fiber quality of FiberX products features tighter bending radiuses, enabling faster and easier installations than comparable products.
