A system enables optical communication with direct conversion of the electrical signal into an optical signal with an array of optical sources. The use of the array of optical sources can eliminate the need for a large serializer/deserializer (SERDES). With an array of optical sources, the optical communication can occur at lower power and lower frequency per optical source, with multiple parallel optical sources combining to provide a signal.

An optical module with directional bias of light beams for improved reception and transmission of optical signals includes a substrate, a photodetector disposed on the substrate, and an optical path control element disposed above the substrate. The optical path control element includes a filter and a reflector. The filter has an upper surface and a lower surface opposite to the upper surface, and the reflector is in contact with the upper surface. A first light beam enters the filter through the lower surface, and is reflected by the reflector to the photodetector. A light source is disposed on the substrate and emits a second light beam. The second light beam is reflected by the lower surface and away from the cavity.

Technologies for connecting data cables in a data center are disclosed. In the illustrative embodiment, racks of the data center are grouped into different zones based on the distance from the racks in a given zone to a network switch. All of the racks in a given zone are connected to the network switch using data cables of the same length. In some embodiments, certain physical resources such as storage may be placed in racks that are in zones closer to the network switch and therefore use shorter data cables with lower latency. An orchestrator server may, in some embodiments, schedule workloads or create virtual servers based on the different zones and corresponding latency of different physical resources.
