TE Wireless Solutions

More efficient & reliable: digital summation of received DAS signals enables all-digital RF end-to-end systems • More energy efficient: others must perform

this summation in the analog domain

• Higher reliability: fewer components increasing MTBF; only one A/D conversion

• Smaller devices possible: fewer components to attain high-fidelity performance

• Easier to adopt new technologies: leveraging datacenter technologies & digital processing

Lowering TCO: innovations that build on CPRI & digital transport provide unique advantages to operators • Fast and simple installation & commissioning;

limited training; site-specific pre-configuration • Utilize planning & RF simulation information for

fast on-site system installation & bring-up • Easy sizing and reconfiguration of fiber plant

using standard optical components

• Reduced sensitivity to workmanship when

handling DAS connectivity components • Fiber installation can be performed by

professionals deploying IT equipment • Digital transport helps make optical links more

robust to installation workmanship

• Enable greener systems by reducing energy consumption of high-performance systems • Digital-only systems can be made more efficient

than analog or ‘hybrid’ solutions • Reducing need for air-conditioning and helping

to reduce carbon footprint

• Lower CAPEX of optical connectivity plant

– building on standard datacenter connectivity • Enables the use of standard datacenter-type

optical transceivers – easy multi-sourcing • No need for more expensive angle-polished

connectors – standard LC and/or MPO type

TE digital systems enable flexible fiber connectivity ‘topologies’ & robust connectivity 14
