Introduction to SFX/C6-UTP-LSZH-D-ORG-305 — Key features at a glance
The SFX/C6-UTP-LSZH-D-ORG-305 is a 305 m reel of Category 6 (Cat6) U/UTP network cable finished in a highly visible orange Low Smoke Zero Halogen (LSZH) jacket. Built for indoor structured cabling, this cable is designed to support Gigabit Ethernet, PoE (Power over Ethernet) devices and common data, voice and CCTV installations. With solid bare copper conductors, a 250 MHz rated frequency and an installer-friendly reel format, it delivers reliable performance while addressing safety and regulatory concerns in enclosed spaces.
Detailed product description: specifications and benefits
This Cat6 cable combines construction choices that matter on real installations. The cable construction is 4 pairs U/UTP with solid bare copper conductors of 0.53 mm diameter, HDPE insulation per pair and a total outer diameter around 6.10 mm. The orange jacket is an LSZH compound (RAL 2003) with a jacket thickness of approximately 0.55 mm and includes a nylon rip-cord to make sheath removal quick and neat. The reel contains 305 m of cable, supplied on a reel-in-box for controlled pay-out during pulls and runs.
- Electrical and performance highlights:Category 6 performance — 250 MHz rating suitable for Gigabit Ethernet (1 Gbps).Solid bare copper conductors deliver low DC resistance (<95 / km @ 20C) and stable signal transmission across long patch and permanent links.Construction tailored for predictable pair performance and reliable termination in keystone jacks and patch panels.
- Safety and mechanical benefits:LSZH jacket reduces smoke density and eliminates halogenated gases during combustion, improving occupant safety and reducing corrosive residues in enclosed environments such as comms rooms, stairwells and public buildings.CPR rating Dca -s2 -a1 -d2 — suitable for many internal building installations (always confirm local requirements).Bright orange color (RAL 2003) improves visibility for identification, segregation and future troubleshooting.
- Installer-friendly format:305 m reel allows long continuous runs and fewer joins.Reel-in-box design and rip-cord speed up deployment in tight or high-volume installations.

Benefits explained: why these specs matter
Each specification of the SFX/C6 reel translates into tangible benefits during design, installation and operation. The solid bare copper conductors give better long-term electrical characteristics and lower resistance compared with stranded conductors, which is important in permanent links and for PoE where small voltage drops can matter. The Category 6 performance rating at 250 MHz ensures the cable supports 1 Gbps Ethernet with margin for typical crosstalk and attenuation encountered in real-world installations.
The LSZH jacket is frequently specified where occupant safety and equipment protection are priorities. In case of fire, LSZH materials emit less smoke and virtually no corrosive halogen gases, which helps protect sensitive electronics in server rooms and reduces health hazards in escape routes. The bright orange jacket also helps installers visually separate network runs (for example, to identify CCTV or voice circuits) and makes future maintenance easier.
Use cases and scenarios where this cable excels
The SFX/C6-UTP-LSZH-D-ORG-305 is a versatile cable suited to a wide range of indoor network applications. Typical scenarios include:
- Office structured cabling:Horizontal and backbone segments in offices and commercial buildings where Gigabit speeds and tidy, safe installations are required.
- Comms rooms and equipment racks:LSZH properties reduce corrosive by-products and smoke, helping protect expensive equipment and personnel in the event of an incident.
- CCTV and security systems:Distinctive orange cable makes routing and identification straightforward for security teams and avoids confusion with other services.
- PoE deployments:Support for PoE devices (access points, VoIP phones, cameras) at Gigabit speeds with solid conductors helps keep power loss minimal across runs.
- Events, temporary installations and internal routes in public buildings:The reel format and high visibility jacket are particularly useful in situations where fast deployment and clear segregation are priorities.
How this cable compares to similar products
Understanding how this Cat6 LSZH cable stacks up against alternatives helps select the right product for the job:
- Versus Cat5e:Cat5e supports 1 Gbps in many scenarios, but Cat6 offers improved headroom (250 MHz rating), reduced crosstalk and better support for higher cable lengths and denser installations. For future-proofing and more consistent Gigabit performance, Cat6 is the stronger choice.
- Versus Cat6a:Cat6a supports 10 Gbps at up to 100 m but typically has larger diameter, higher cost and stiffer handling. If your project requires 10 Gbps or maximum alien crosstalk suppression, Cat6a is appropriate; if you need reliable Gigabit and easier installation at lower cost, Cat6 is often the pragmatic option.
- LSZH versus PVC jackets:LSZH prioritizes safety and reduced corrosive emissions but can be slightly more expensive than PVC. PVC jackets remain common where fire safety rules permit. For enclosed public areas, stairwells or where local codes require low-smoke materials, LSZH is preferred.
- U/UTP (unshielded) versus shielded variants:U/UTP is lighter, more flexible and easier to terminate than shielded cables. In electrically noisy environments or where external interference is a known concern, shielded options (e.g., F/UTP, S/FTP) can offer benefits but require proper grounding and different terminations.
Customer feedback and installer impressions
While individual project results vary, installers and network technicians commonly report the following practical observations for this style of cable:
- Easy pay-out from the 305 m reel reduces time spent re-joining or swapping reels during long horizontal runs.
- Solid conductor construction simplifies terminations for punch-down blocks and solid-core RJ45 outlets, giving consistent performance in permanent links.
- The orange LSZH jacket improves visibility in cable trays and risers, making segregation and troubleshooting faster.
- Installer notes often highlight the importance of following termination and testing guidelines to ensure Cat6 performance is preserved (proper pair handling, controlled bending radius and suitable connectors/patch panels).
If you require formal customer testimonials for procurement or marketing purposes, request project references or datasheet-backed performance results from the supplier or distributor prior to purchase.
Installation notes and compliance
To achieve rated Cat6 performance and to meet safety expectations, installations should follow standard cabling practices: avoid tight bends, keep cable runs away from high-voltage conductors, maintain pair untwist lengths to a minimum at terminations, and use certified RJ45 jacks and patch panels designed for Cat6. Check local building regulations and project specifications for required CPR classes and confirm that the Dca rating is acceptable for the intended location. Perform post-installation testing (wiremap, NEXT, attenuation and return loss) to verify the link meets Cat6 requirements.
