The rapid growth of Internet use and bandwidth-intensive applications combined with routine transmission of large files is driving the need for 10 Gigabit Ethernet (10GbE) in many network backbone and data center connections. Implementation is happening all around us. Sales of 10GbE switch ports are increasing dramatically, and will continue to grow over the next decade. With increased network speeds comes a rise in the significance of fiber optic cabling and connectivity. Most data centers today have equal amounts of fiber and copper terminations, and fiber links are vital to carrying backbone traffic to and from a large number of sources. With many grades to choose from, selecting the right fiber type for your network can be an overwhelming task. Careful consideration of price, bandwidth, and distance is critical to choosing fiber today that will support requirements in the future. Laser-optimized 50µm multimode fiber offers many benefits for both today's and tomorrow's network and data center applications, and it may be the key to maximizing your investment. An Inevitable Shift Although 50µm multimode fiber was developed 10 years prior to , North America adopted fiber distributed data interface (FDDI)-grade fiber for Ethernet in the late 1980s. At that time, connectorization and alignment were not as controlled as they are today, and the larger-core was ideal for use with larger light-emitting diode (LED) transmitters. As backbone speeds increased to Gigabit Ethernet, LED signaling technology was no longer a viable solution. With a maximum modulation rate of 622 Mbps, LEDs could not be turned on and off quickly enough to support the higher bandwidth. This caused the industry to shift to low-cost vertical- cavity surface emitting .
