MPO Connector – Ready for business

Improved design and engineering efforts make the interface a strong asset, not a weak link. As the industry deploys 40-Gbit/sec optical networks and moves ahead to 100-Gbit/sec data rates, service providers and data center managers may question whether the multi-fiber push-on (MPO) connector can perform reliably at those speeds. They saw the first-generation MPO as[…]

SMP – Symmetric Multiprocessing

In computing, symmetric multiprocessing or SMP involves a multiprocessor computer hardware architecture where two or more identical processors are connected to a single shared main memory and are controlled by a single OS instance. Most common multiprocessor systems today use an SMP architecture. In the case of multi-core processors, the SMP architecture applies to the[…]

DWDM – What is DWDM?

Short for Dense Wavelength Division Multiplexing, an optical technology used to increase bandwidth over existing fiber optic backbones. DWDM works by combining and transmitting multiple signals simultaneously at different wavelengths on the same fiber. In effect, one fiber is transformed into multiple virtual fibers. So, if you were to multiplex eight OC -48 signals into[…]

The Royal Institute of British Architects (RIBA) Plan of Work Stages

¬†The RIBA Plan of Work describes the activities from appraising the client‚Äôs requirements through to post construction. The stages are also used in the appointment of architects and¬† help to identify consultant services and indicate the resource and fee total by Work Stage. The information below is in accordance with CABE principles (Creating Excellent Buildings:[…]

Calculating PUE

Power Usage Effectiveness (PUE) Power Usage Effectiveness (PUE) is a standard developed by The Green Grid‚Ñ¢ consortium to provide a clear answer to the primary issue surrounding energy efficiency within the data center which is how much power is devoted to driving the actual computing/IT components (servers, for example) versus the ancillary support elements such[…]
