The CAT6A 10Gig UTP modular jacks provide transmission performance beyond 500MHz and Alien Crosstalk requirements exceeding the industry standards set by ANSI/TIA-568-C.2 for supporting the operation of 10Gig Ethernet applications (10GBASE-T). It is designed with a shielded termination cap which minimizes additional AXT from neighboring connectors. It also features twisted pair separation posts which minimize the untwisting of pairs to allow for efficient installation and long-term peak performance. The modular jacks are also backward compatible supporting current CAT6, CAT5e, and voice network applications.

For now, LED light fixtures are substantially more expensive than their glass competitors. But LED lighting brings significant advantages that Ruud Lighting executives think will steadily steer the industry toward LED — and toward Ruud.
Those advantages include: Energy savings. LEDs are about 50 percent more efficient than high-pressure sodium or metal halide, 35 percent more than fluorescent and 80 percent more than incandescent, said Christopher Ruud, executive vice president for national accounts at Ruud Lighting. Long LEDs, when properly engineered, last more than five times longer than metal halide. This reduces environmental waste and also maintenance. They are vibration- and impact-resistant, making them virtually vandal-proof. They contain no mercury, unlike fluorescent bulbs .
And, when properly engineered, LED life is more than five times that of metal halide, reducing environmental waste. They give much truer, whiter lighting than sodium lights.
Under high-pressure sodium, which is widely used in street and parking area lighting, Any of the dark colors all look the same, Ruud said.
But LED lighting renders true colors of cars and clothing. Asked who cares, Ruud replied, The police care. They care a lot. Better, more even light control
