Corning Cable Systems introduces optical, wireless technologies

March 18, 2004
March 18, 2004 - Two fiber-optic product lines address security issues, while an upgraded wireless system raises speeds and extends distance.

Corning Cable Systems (CCS--www.corning.com/cablesystems) recently introduced three new technologies - two specifically for optical networks and one aimed at sites where optical connectivity is not feasible.

The company's Ruggedized Ribbon Cable Assemblies are designed for government or other facilities that require physical segregation of multiple-classification networks. The assemblies are available with 24, 36, or 48 fibers organized into easily identifiable 12-fiber ruggedized ribbons. They are designed to meet National Security Telecommunications and Information Systems Security (NSTISSI) requirements as a protected distribution system (PDS).

By serving as the PDS, Ruggedized Ribbon Cable Assemblies offer space and cost savings over traditional PDS installations, while also providing the benefits of optical-fiber cables. The cable assemblies minimize deployment cost and complexity by reducing metal conduit and encryption requirements, while also improving network performance to maximize personnel productivity. This PDS alternative also makes incremental cable addition easier than in traditional systems.

The assemblies are available with 12-fiber MTP connectors and are available in multimode, singlemode, and hybrid versions. They meet the requirements of the National Electrical Code 770, Article 770-51(A) and NFPA 262 flame tests.

CCS's Keyed MT-RJ solution was developed for government customers who, because of different security classifications, must run physically segregated networks to work areas. The solution prevents accidental or intentional connection to the wrong network by offsetting one of the existing MT-RJ alignment keys to four different positions. To identify the offset key positions, components are color-coded blue, green, red, and yellow.

As aprt of the solution CCS's Keyed MT-RJ Connector Panels are available in both 12- and 24-fiber versions, offering customers a product for high-density applications. The Keyed MT-RJ adapter uses the patented dual-polarity feature to ensure system polarity. The solution uses standard UniCam MT-RJ connectors coupled with color-coded boots for identification, providing the installer with the well-known benefits of the patented Continuity Test System visual indication of proper field fiber insertion. Keyed MT-RJ patch cords complete the solution.

Corning Cable Systems' Keyed MT-RJ Solution is fully intermateable with other keyed systems using the same four colors.

Finally, Corning Cable Systems' FreLink 3.0 Optical Transmission Equipment is part of the company's LANscape Solutions for Free-Space Optics (FSO). Version 3.0 includes new tracking features.

The company says its LANscape Solutions for FSO is an ideal cost-per-bit solution for enterprise campus networks in need of connectivity where an optical-fiber cable link is not feasible due to right-of-way or other complications. FreeLink Optical Transmission Equipment consists of two linkheads mounted within line of sight of each other on rooftops or behind windows, whereby data and voice traffic can be transferred.

FreeLink 3.0 Optical Transmission with tracking is a diverse multiple-beam transmit-and-receive FSO product for transmission speeds up to 2.5 Gbits/sec and distances up to 4,000 meters. Instead of fixed lasers, the equipment features multi-beam array tracking, which accommodates for the effects of building sway.

Added features also include automatic power control, whereby power is adjusted for varying weather conditions, new beam geometry, and a new power supply. FreeLink 3.0 Optical Transmission Equipment with tracking has no minimum deployment distance.

Corning Cable Systems also offers FreeLink 1.0 Optical Transmission Equipment, a single-beam FSO product designed for shorter-range, rapid deployment and redeployment of networks from 1.5 to 155 Mbits/sec up to 1,000 meters. FreeLink 3.0 Optical Transmission Equipment is a four-beam product that offers speeds up to 1.25 Gbits/sec up to 4,000 meters.
