WARP solution for unshielded 10GBase-T

Innovative technology uniquely combines the superior protection of shielded cable with the convenience of unshielded cable. To achieve this, the system is partially ‘shielded’ by adding short, isolated sections of shielding (metal foil) to the cable. Because there is no continuous shielding, it does not need to be earthed. The length of each shielding section is chosen so that no standing waves can develop and produce negative effects in the frequency range up to 500MHz. Used in system, WARP technology allows ANEXT reserves that were previously only possible with shielding. This means there is no need for follow-up measurements of this parameter in the installation. Measurements are guaranteed by the layout of individual components. WARP cables offer a further advantage for Power over Ethernet (PoE). The integrated aluminium foil and thin cable sheath ensure heat generated in this cable by power transfer is lower than in comparable traditional cables, reducing ageing of plastic materials and allowing longer cable runs.

OFS is offering graded index HCS ® (GiHCS) optical fibre in LSZH cable construction and crimp and cleave SC connectors. Using the SC crimp and cleave hand tools, technicians can quickly install fibre connectors in industrial spaces, and rapidly repair damaged optical fibre cables. The advantages of the new SC connectors are said to include a wide operating temperature range (-20ºC to +105ºC); abrasion, vibration and chemical resistance; and high tensile strength.

TRADITIONALLY, Reichle & De Massari has a strong leading position in technology for both shielded and unshielded systems for data centres, office cabling and fibre-optic technology. This makes it possible for the company to offer professional, unbiased advice to the customer to find the optimum solution together, be it shielded or unshielded, to last through several generations of active equipment. The newly introduced WAve Reduction Pattern (WARP) technology is a prime example. This accommodates the demands placed on such systems by the rapid uptake of 10GBase-T data transmission. Transmitting at 10 Gbit/s involves the use of a sensitive, high frequency coding method. The sampling rates and the number of voltage values are many times higher than for 1000Base-T. As a result, susceptibility to interference increases by a factor of 100, due to the slight differences in potential between input signals from one bit level to the next. This is caused by the rise in cable attenuation at these high frequencies, and by the increased coding. In order for 10GBase-T to work correctly, it is crucial to control and suppress interference from outside the cables. OFS has launched its new SC crimp and cleave connectivity solution for industrial networks. The rapid adoption of industrial ethernet has led to new demands in factory automation and industrial networking applications that requires the introduction of industrialised communications systems. Fast (100Mb/sec) and Gigabit (1,000Mb/sec) ethernet data rates demand higher bandwidth and real-time, low-latency communications. The increasing use of intelligent electronic devices, utility-grade rugged IP routers, and ethernet switches is driving a move to IP-based communications on the production floor.
