FEATURES OVERVIEW • All feature tight-buffered fiber with an acrylate fiber coating and aramid yard strength members. • Use with either LED or laser light sources. • With a laser light source, bandwidth increases to 2000 MHz/km. • Use the cable in 10-Gigabit Ethernet runs up to 300 meters, making it ideal for backbone and campus connections. Thinking of upgrading to 10-Gigabit Ethernet? Here’s the laser-optimized 50-micron cable you want. Since 10-Gigabit Ethernet (10-GBE) was ratified in June 2002, the move is on to upgrade Ethernet networks. 10-GBE is a logical extension of previous Ethernet versions and was designed to make the transition from LANs to Wide Area Networks (WANs) and Metropolitan Area Networks (MANs). 10-GBE offers a cost-effective migration for high-performance and long-haul transmissions at up to 40 kilometers. Its most common application now is as a backbone for high-speed LANs, server farms, and campuses. It also enables you to connect geographically separated LANs to new MANs and WANs via dark fiber, dark wavelengths, or SONET/SDH networks. 10-GBE supports existing Ethernet technologies. It uses the same layers (MAC, PHY, and PMD), and the same frame sizes and formats. But the IEEE 802.3ae spec defines two sets of physical interfaces: LAN (LAN PHY) and WAN (WAN PHY). The most notable difference between 10-GBE and previous Ethernets is that 10-GBE operates in full-duplex only and specifies fiber optic media. The chart shown at right notes the differences between Gigabit and 10-Gigabit Ethernet. Choose from three styles: • Zipcord patch cable with a PVC jacket. • Bulk distribution-style cable with a PVC or plenum jacket. • Bulk zipcord cable with a PVC or plenum jacket. You can use these cables with LED or laser light sources. Because the cable is optimized for a laser light source, bandwidth increases to 2000 MHz/km with one. This cable is ideal for use in 10-Gigabit Ethernet runs up to 300 meters, making it ideal for backbone and campus connections.
