Announcing the next generation of fiber optic cables!
10 Gigabit - 50 um - "Xcelerate Plus™" InfiniCor SX™
Multimode Fiber Optic Cables
 With the increased bandwidth consuming applications such as Multimedia, Streaming Audio/Video, and Peer-Peer Networking, these next generation fiber optic cables provide the much needed capacity for bandwidth and performance. Enter 10 Gigabit Ethernet.
These new technology 50um fiber optic cables from Lightguide™ provide nearly 3 times more bandwidth than conventional 62.5um Multimode Fiber Cables rivaling performance available in only Singlemode Fiber Cables, with much reduced cost. Made with Corning™ Xcelerate™ 50 micron multimode fiber.
Using Multimode electronics, besides being 2-3 times less expensive than singlemode electronics, also lower costs due to lower power consumption and less stringent maintenance requirements. These new cables offer performance at singlemode speeds with multimode economics while providing and easy upgrade path for future network requirements.

10-GiG Ethernet White Paper
Q1: Do InfiniCor® SX+ fiber patch cords need to be used with InfiniCor SX+ fiber cable to achieve 10 Gb/s over 300 meters?
The pending TIA 568-B.3-A.1 Addendum in the 10 Gigabit Ethernet (GbE) standard has specified that to achieve the minimum distance of 300 meters at 10 Gb/s using 850 nm sources the patch cords must contain fiber of the same type and performance as used in the optical fiber cabling. Therefore, to achieve at least 300 meters at 10 Gb/s both the optical fiber cabling and patch cords must contain InfiniCor SX+ fiber.
Q2: A) Why is InfiniCor SX+ fiber a 50 µm product, and not a 62.5 µm product? B) Is the Premises market moving towards 50 µm, and why?
Two excellent questions! The answer to both is tied to the inherently higher bandwidth that can be achieved with 50 µm fibers vs. what can be achieved with 62.5 µm fibers. 50 µm fibers have a smaller fiber core size and thus less modal dispersion, which leads to higher bandwidths. A higher bandwidth fiber enables faster data rates at longer distances. In fact, the IEEE 802.3ae 10 Gigabit Ethernet standard has determined the minimum distances that can be achieved with multimode fibers, which is shown in the chart below. As you can see 50 µm fibers are capable of achieving much longer distances at 10 Gb/s than 62.5 µm fibers, and as such, the IEEE 10 Gigabit Ethernet standard has specified an enhanced 50 µm fiber as the only multimode solution to achieve 300 m at 10 Gb/s. However, 50 µm fibers are not limited to 10 Gb/s applications. 50 µm fibers' high bandwidth also enables much longer distances at 1 Gb/s (Gigabit Ethernet) than 62.5 µm; 550 meters at Gigabit Ethernet speeds with 50 µm fiber vs. only 275 meters with 62.5 µm fiber.
The Premises industry is realizing the benefits of 50 µm fiber, and we are observing a shift in preference from 62.5 µm fiber to 50 µm fiber. Corning Optical Fiber encourages its customers to consider using 50 µm fiber for both new installations and system-wide upgrades.
Q3: Why is a 10 Gb/s capable MMF product important since no one is running at 10 Gb/s now?
With the rapidly growing demand for bandwidth, many network managers foresee a need for increased capacity in the backbone beyond Gigabit Ethernet. In fact, an overwhelming 78% of respondents to our webcast poll stated that a 10 Gb/s capable cabling solution will help alleviate their organization's bandwidth concerns right now!
As network managers plan for the future, they would like to install a high-bandwidth fiber now to meet their current needs, and migrate to 10 Gb/s capability as their bandwidth needs grow. InfiniCor SX+ fiber will provide them with this migration path without the need to recable. Additionally, there are several applications where a low-cost 10 Gigabit Ethernet solution would be of great benefit to network managers, such as in server farms, storage area networks and private to public network connections.
