Fiber-to-the-Desk Application Note
In today’s networks, fiber optic cabling is frequently used as the backbone of communications network cabling, from the entrance into a building to various telephone/data equipment closets serving users on different floors of the building. But now, more and more organizations are capitalizing on the benefits of fiber optic cable to connect directly to desktops, laptops, or other communications equipment. “Fiber-to-the-Desk” (FTTD) refers to the extension of the fiber optic infrastructure directly to user locations.
Here are some of the many advantages to using fiber optic cable to connect to the main fiber network directly at the desktop:
Fiber optic cable is immune to electromagnetic interference (EMI) and radio-frequency interference (RFI), and is therefore more challenging for hackers to tap. Because copper cables emit electromagnetic signals, hackers can read data from nearby without physically touching the lines. Machinery, fluorescent lights, and radio signaling equipment used for communications, including wireless communications, can also create EMI and RFI. In contrast, fiber optic cable uses light that is completely shielded so hackers would have to physically splice into the line, which is difficult to do and easily detected. For organizations concerned with data security, fiber optic cable is the most secure option.
Bandwidth and Distance
Fiber optic cable has the ability to support higher data rates than any other cable type, with capacity to transmit hundreds of terabits per second. As demand for more data-intensive applications continues to increase, fiber cable will offer the best bandwidth to accommodate it. As adoption of 10 Gigabit Ethernet becomes increasingly more common, 40 and 100 Gigabit Ethernet will follow. Although higher grades of twisted pair cable are allowable for transmitting these high bandwidth signals, they will only be able to do so over very short distances. Therefore, fiber optic cable is the best choice for transporting higher speed and higher bandwidth signals over longer distances.
Lower Overall Cost
The advantages of fiber allow network designers to centralize their network equipment in one MDF or wiring closet and run fiber cables to each work area throughout a building, rather than having a separate equipment closet on each floor. When the number of equipment closets is reduced, the amount of space, power, heating, ventilation, and air conditioning equipment required is also reduced. Centralization of network management also reduces the number of maintenance or troubleshooting locations, allowing for more efficient use of equipment and personnel. Testing and documentation likewise becomes less cumbersome with fewer locations. Though the initial cost of fiber equipment may be slightly higher than copper, the benefits realized can save organizations significant cost in the long term.
With fiber cabling offering the best security, bandwidth, distance, and lower overall cost, it also offers the longest useful life because of its ability to handle the resulting changes in technology.
Fiber to the desk can be used for mission critical networks, virtual networks, and LAN networks. It is useful for increasing bandwidth availability, moving large amounts of data at high transmission rates, and for bringing service to locations where power is limited or unavailable. It also provides a more secure connection for organizations who are concerned about tapping or other security vulnerabilities. FTTD is particularly useful for:
- Enterprises and Business Campuses
- Banks, Online Brokers and other Financial Institutions
- Healthcare Organizations
- Colleges and Universities
- Local, State, and Federal Governments
- Sports and News Broadcast Agencies
