From Optical Networking Best Practices Handbook

Today, many large enterprises find themselves attempting to meet what appear to be two diametrically opposed objectives. On the one hand, these enterprises are looking for ways to utilize IT as a competitive advantage, using it to enhance the flow of information and improve the access to applications across the entire enterprise, ultimately increasing employee productivity. On the other hand, enterprises must manage costs—in particular, the total cost of IT. The management teams at these large enterprises recognize that storage and server consolidation/centralization provides the most effective means to leverage and share their information assets so that employees can collaborate effectively and content can be delivered efficiently. Management also recognizes, however, that centralization of computing resources will not deliver the desired employee productivity improvements unless it is accompanied by a significant increase in bandwidth to insure that network users are able to quickly access these centralized resources. Of course, significantly increasing available bandwidth using traditional access solutions results in a dramatic increase in the total cost of IT, moving the enterprise further from its second objective of managing costs [1].

These same large enterprises frequently utilize an ATM, frame relay, or leased-line infrastructure to connect their metro sites. Enterprises are...

Products & Services
Fiber Optic Cables
Fiber optic cables are composed of one or more transparent optical fibers enclosed in protective coverings and strength members. Fiber optic cables are used to transmit "light" data.
Wavelength Division Multiplexers (WDM)
Wavelength division multiplexers (WDM) are devices that combine light signals with different wavelengths, coming from different fibers, onto a single fiber. They include dense wavelength division multiplexers (DWDM), devices that use optical (analog) multiplexing techniques to increase the carrying capacity of fiber networks beyond levels that can be accomplished via time division multiplexing (TDM).
Resistors
Resistors are electrical components that oppose the flow of either direct or alternating current. They are used to protect, operate, or control circuits.
Chip Resistors
Chip resistors are passive resistors with a form factor of an integrated circuit (IC) chip. Typically, they are manufactured using thin-film technology.
Current Sensing Resistors
Current sensing resistors convert the current flowing through it to a voltage drop. Monitoring or measuring this voltage drop allows the current through the resistor to be measured. Applications for current sensing resistors include power supplies, receptacles, and battery packs.
