NeoPhotonics designs and manufactures a broad range of products for optical communications networks and a variety of other applications, where the networks operate at speeds less than 100G. These products are key elements of direct detect long haul and metro DWDM networks as well as mobile backhaul and fronthaul networks. NeoPhotonics offers a wide range of application-specific passive optical functionalities in modules or subsystem configurations. These include athermal arrayed-waveguide grating (AWG)-based drop modules for multiplexing and demultiplexing in conventional ROADM nodes as well as variable optical attenuators and tap power monitors for network monitoring and control. NeoPhotonics combines several of these functions together in subsystems such as the VMUX, which combines up to 48 variable optical attenuators and an arrayed waveguide grating multiplexer in a single compact unit. In addition, many of these products provide high-bandwidth connections to base station antennas for mobile devices and to people and machines over fixed and wireless networks. As consumer connectivity speeds have increased through the transitions from 2G to 3G to 4G/LTE, and now to 5G, the bandwidths necessary to aggregate and connect wireless traffic into the backbone network, including Mobile Backhaul, have also increased. NeoPhotonics offers 10G EML lasers, laser drivers, modulator drivers, and photodiode receivers designed with the necessary bandwidth for connecting 4G/LTE wireless base station antennas.
