Black Box Explains...FDDI
Fiber Distributed Data Interface (FDDI) is a networking standard for operating at speeds of up to 100 Mbps. The standard FDDI network is set up in a ring topology with... more/see it nowtwo rings that transmit signals in opposite directions to a series of nodes. FDDI accommodates up to 500 nodes per dual-ring network with spacing up to 2 kilometers between adjacent nodes. FDDI uses the same token-passing scheme as the IEEE 802.5 Token Ring network to control transmission around the loop. collapse
Black Box Explains... Single-Mode Fiber Optic Cable
Multimode fiber cable has multiple modes of propagation—that is, several wavelengths of light are normally used in the fiber core. In contrast, single-mode fiber cable has only one mode of... more/see it nowpropagation: a single wavelength of light in the fiber core. This means theres no interference or overlap between the different wavelengths of light to garble your data over long distances like there is with multimode cable.
What does this get you? Distanceup to 50 times more distance than multimode fiber cable. You can also get higher bandwidth. You can use a pair of single-mode fiber strands full-duplex for up to twice the throughput of multimode fiber cable. The actual speed and distance you get will vary with the devices used with the single-mode fiber. collapse
Black Box Explains... Why go wireless?
• Its great for communicating in harsh climates or in areas where its expensive to run cable. Wireless solutions are well suited for use in military applications, farming, refineries, mining,... more/see it nowconstruction, and field research.
• Because sometimes you just cant run wire, like in historic buildings or hazmat areas.
• When its physically or legally impossible to support conventional hard-wired RS-232 communications, wireless networking may be your only answer.
• It gives you quick, temporary connections at trade shows, and fast reconfigurations—even troubleshooting or remote field testing.
• It provides reliable disaster relief when all else fails! Count on wireless networks to maintain mission-critical links when disaster strikes.
• Its more affordable, more reliable, and faster than ever before.
• Best of all, no FCC licensing required! collapse
