Cloud, mobile, and residential broadband services are driving the demand for higher bandwidth and pushing fiber closer to customer premises. Today, broadband wireline access networks are deployed by telecom and cable TV service providers that need to offer a competitive array of features, services, and bandwidth to gain and retain consumer and enterprise customers. To support these new offerings, service providers continuously upgrade their existing wireline access networks to higher data rates with next-generation optical communications technology.
Broadband Wireless Access
The rapidly growing adoption of smartphones and other mobile devices in consumer electronics has driven upgrades in the radio access networks from 3G to 4G. New exciting use cases in automotive, consumer electronics, and healthcare, as well as increasingly networked cities, factories, and farms, are driving wireless upgrades to 5G globally. These upgrades require new antenna RF technologies, which in turn require bandwidth upgrades in the optical infrastructure that links the large number of wireless base stations to the optical transport network. With each new generation of wireless technology, remote radio heads move closer to antennas. Base stations are linked to remote radio heads through fronthaul fiber-optic links, driving a large new market for optical transceivers that can operate at extreme temperatures. With 5G wireless, bandwidth upgrades in fronthaul links are driving upgrades in midhaul and backhaul networks with dense wavelength division multiplexing (DWDM) transmission technologies. 5G RF technology is increasingly leveraging a new generation of devices fabricated on SiC substrates due to their high breakdown voltage, high current and power density, high power, added efficiency, and gain.
