  • Value is a concept that many equipment vendors talk about, especially when the subject concerns T1 service delivery equipment. But unlike some companies that just talk about value in shallow market- ing terms or catch phrases, ADC Telecommunications demonstrates true value – manifest and validated in actual cost savings and performance efficiencies in carrier operations. To experience this value, however, carriers must take a fundamentally different approach to the way they deliver T1 access circuits...

  • Consider the spontaneous emission term describing the contribution of the spontaneous emission to the laser oscillation, which appears as the final term on the right-hand side of the rate equation for the photon density (Eq. (6.21)). Since this term represents the component of the spontaneous emission belonging to the same mode as the laser oscillation (angular frequency !m), it is closely related to the gain for the oscillation mode. Consider a laser of index-guiding type, and let E ¼ E(r) ¼ E(x, y)E(z) be the complex electric field of the oscillation mode. ...

  • A Connector is a device used to provide a semi-permanent link between two optical fibers. Connectors must be able to maintain good optical contact between the fibers at the connector interfaces. In theory, only the cross sectional face of the two fibers need to touch, hence the term Physical Contact (PC) connector is used. The basic components of a connector include the body, the ferrule, the barrel (coupling nut/insert), and the boot. The body is the physical shell of the connector, which houses the mechanism used to secure the fiber to the connector.
