Physics / mechanism
Communications equipment spans hardware enabling signal transmission across wired, wireless, and optical media: routers, switches, base stations, optical transceivers, RF front-ends, and satellite terminals. Core physics involves modulation schemes (QAM-4096, OFDM), signal propagation, amplification (EDFA, GaN PA), and multiplexing (DWDM, MIMO). Key parameters: bandwidth (400G–1.6T per lane in datacom), noise figure (<1 dB in LNA design), power efficiency (pJ/bit), and latency. Market ~$500B globally; dominated by Cisco, Huawei, Ericsson, Nokia, Ciena, and Infinera in optical. Transition to 800G/1.6T coherent optics and Open RAN disaggregation are current structural inflections.
Competitive landscape
Competing and adjacent segments include compute infrastructure (GPUs increasingly handling baseband DSP), satellite constellations (SpaceX Starlink, AST SpaceMobile commoditising terrestrial backhaul), and silicon photonics eating into InP-based optical module share. Wireless vs. wireline arbitrage continues. Key substitution risk: co-packaged optics (CPO) collapsing the transceiver module market into hyperscaler-controlled ASIC packages.
