FUTURE TRANSPORT CONNECTIVITY

INTRODUCTION

Transport networks are becoming more connected, more data-driven, and more demanding. Expectations for communications continue to rise as rail and road infrastructure needs to support growing mission-critical and commercial applications.

The Challenge This challenge is compounded as operators navigate a shift in communication standards. Rail networks are transitioning from GSM-R to FRMCS, while 5G-based applications are being deployed more widely across transport environments, and 6G developments are on the horizon.

The result is that transport operators need a communications backbone that can support current operational needs while providing a clear path to future standards. At the same time, they must navigate the physical realities of rail and road deployments, including difficult underground and tunnel environments, performance in harsh conditions, and achieving maximum capacity and performance over long distances.

The Solution RFS supports these requirements with optical fiber and radiating cable solutions engineered for exceptional performance, network evolution, and long service life across rail and road deployments.

GYFZS53+33 Designed for metropolitan access network and trunk network deployments requiring fire resistance and enhanced mechanical protection. GYFZS53+33 is suitable for heavy-duty installations where high tensile strength and crush resistance are needed.

Single-mode or multimode fibers are housed in loose tubes made from high-modulus plastic. The tubes are stranded around a central strength member to form the cable core, which is filled with a compound and surrounded by an inner PE sheath. This is wrapped in fire-resistant tape, a layer of corrugated steel tape, and a LSZH middle sheath. This is then wrapped with steel wire and a PE outer sheath.

Features • Precise manufacturing for superior mechanical and temperature performances • Strong hydrolysis-resistant loose tubes • Fire-resistant layer combined with LSZH sheaths for enhanced fire performance • Excellent crush resistance • Complies with IEC6033l{no cooling), IEC60754-1&2, IEC61034 and IEC60332-2-24

SAFETY IS KEY

RFS BURN CHAMBER

ROBUST JACKET CONSTRUCTION ENABLES THE HIGHEST CPR CLASSIFICATIONS RFS CPR-compliant coax, fiber, power and radiating cables feature a specially developed jacket that allows them to achieve best-in-class ratings for burning droplets (d0), low smoke emission (s1) and corrosivity (a1), the most important criteria for fire safety in cables that are installed indoors and underground.

All RFS cables are tested and certified by an external notified body according to EN 50575. In addition, RFS’ manufacturing facility in Hannover, Germany, has been audited and meets the highest system 1+ requirements for type approvals, regular production audits, as well as regular sampling and testing of products by the notified body.

FIND CPR-COMPLIANT CABLES FOR ANY APPLICATION All RFS CPR-compliant cables are also designated as low-smoke, zero-halogen (LSZH) and meet International Electrotechnical Commission (IEC) standards for flame spread, smoke acidity and low smoke emission. They are compatible with existing RFS connectors, factory-assembled jumpers, grounding kits and clamps, as well as trimming and preparation tools.

RFS HANNOVER BURN CHAMBER The burn chamber, installed in 2024, extends RFS's testing capabilities and operates in accordance with the international standard EN50399 which refers to the important CPR (Construction Product Regulation) directive of the European Union.

Combined with existing fire testing facilities, it gives RFS one of the most comprehensive in-house fire resistance testing capabilities of any organization in the cable space. This will allow RFS to continue offering solutions that meet fire safety standards worldwide.

CPR-COMPLIANT CABLES ARE IDEAL FOR INDOOR APPLICATIONS A BROAD PORTFOLIO OF CPR-COMPLIANT CABLES FOR INDOOR APPLICATIONS Since July 1, 2017, all communications cables installed in buildings in the European Union (EU) must meet the fire performance requirements in European standard EN 50575 and include the CE marking to comply with EU Construction Products Regulation (CPR) No. 305/2011.

RFS was the first cable vendor to offer RF communications cables with the highest CPR classifications for fire safety.

Today, we offer a wide range of CELLFLEX® coaxial cables , RADIAFLEX® radiating cables and HYBRIFLEX® Fiber and power cables that comply with European CPR No. 305/2017. This directive requires that coax and radiating cables meet the fire performance standards in the EN 50575 standard and be classified according to the EN 13501-6 standard.

RFS cables are classified according to the CPR test standards and criteria listed below.
