Corning debuts bend-insensitive solution for data centers

Aug. 1, 2009
Corning Cable Systems says its recently introduced LANscape Pretium Evolved-Density, Growth-Enabled (EDGE) products are designed as high-density pre-terminated optical cabling solutions for data center installations.

Corning Cable Systems (www. corning.com/cablesystems) says its recently introduced LANscape Pretium Evolved-Density, Growth-Enabled (EDGE) products are designed as high-density pre-terminated optical cabling solutions for data center installations.

The company claims that Pretium EDGE Solutions allow for up to 35% faster deployment, enable up to 25% faster moves, adds and changes (MACs), and offer up to 100% more density than traditional pre-terminated solutions.

Enabled by ClearCurve multimode fiber, Pretium EDGE solutions feature pre-terminated and tested multi-fiber assemblies or trunks, with a minimum bend radius as small as 5x the outer diameter of the cable, compared to 10x for traditional trunks. The EDGE trunks are an average of 30% smaller than traditional trunks, says Corning.

ClearCurve made its debut in January, with a promised 10x improvement in bend performance over other multimode fibers used in the data center. The cable is designed to be more tightly routed around corners and bends, while interconnect cables offer a minimum bend radius of up to 8x the outer diameter. Housings are available in 1U and 4U sizes, and mount in 19-inch racks or cabinets. When combined with Pretium EDGE trunks and jumpers, the housings can provide LC connector termination density of 576 fibers within a single 4U housing. Housings contain 12 sliding trays that can accommodate as many as four 12-fiber LC modules or four 24-fiber MTP connector panels per tray.

Modules and harnesses load from either the front or the rear, and correct fiber polarity is guaranteed throughout the systems’ link. With modules offering an insertion loss of 0.5 dB, Corning says multiple connections in a network link are allowed when deploying a TIA-942-compliant system.
