The local area network (LAN), the foundation of enterprise connectivity, has been around for a long time. The first LANs were created in the 1960s to support the need for connections among computers at colleges and universities. They were made from coaxial cabling and used IBM’s Token Ring. The modern-day Ethernet competitor was wildly popular in the early 1980s as a way to connect computers together in a, you guessed it, ring format.
The next evolutionary step for the LAN was copper cabling, first introduced some 40 years ago. For a long time, copper-based LAN became a synonym for the LAN and many companies still rely on this technology today. But, while copper-based LANs worked well before the Internet of Things and the cloud era, today they simply can’t meet the needs of the 21st century.
Copper-based LANs offer limited speeds and bandwidth. To upgrade the network to meet their evolving network needs, companies must add more and more equipment, regularly tearing out the entire copper-based network and replacing it with new cabling and equipment. In addition, copper can easily be tapped into, compromising data security.
With ever-changing network needs, it’s time for the LAN to evolve again as well. The future of LANs is in fiber optics. Fiber-based passive Optical LAN is the natural next step for networks because it enables companies to meet their needs today and in the future. Tellabs Optical LAN equips companies with the tools needed to provide a future-proof network, including:
- Virtually unlimited bandwidth and speeds
- Flexibility to support next-gen security, as fiber is not susceptible to electromagnetic and radio frequency interference, making it much less susceptible to intrusion than copper
- Six nines of availability, reducing unplanned network downtime to less than 30 seconds a year, which is critical in the cloud an Internet of Things era
