The increasing data traffic is expected to propel the growth of the optical transport network (OTN) hardware market in the future. Data traffic refers to the amount of digital data transmitted across communication networks through various devices and applications. Data traffic is rising as more users stream high-definition and on-demand videos, which require large bandwidth and increase overall network data usage. Data traffic influences the demand and capabilities of optical transport network (OTN) hardware by determining the volume, speed, and type of data to transmit, requiring OTN equipment with higher capacity, faster switching, and efficient multiplexing to enable low-latency, reliable, and scalable optical communication. For instance, in June 2024, according to Ericsson, a Sweden-based telecommunications company, from the fourth quarter of 2023 to the first quarter of 2024, mobile network data traffic experienced a quarter-on-quarter growth of approximately 6 percent. The total global mobile network data traffic for the month reached 145 exabytes (EB). Therefore, the increasing data traffic is driving the growth of the optical transport network (OTN) hardware market.

Major companies operating in the optical transport network (OTN) hardware market are focusing on developing innovative products such as linear amplifiers to enhance network performance and meet growing data traffic demands. A linear amplifier is an optical device that strengthens transmitted signals in a fiber optic network while preserving their original waveform, ensuring signal integrity over long distances. For instance, in July 2024, Anritsu Corporation, a Japan-based telecommunications and measurement solutions provider, launched its 14 Gbaud PAM4 wideband/high-output (2 Vpp) linear amplifier, designed to improve high-speed optical transmission performance and support the growing demands of hyperscale data centers and ultra-fast networking applications. This amplifier features an exceptionally wide frequency response from 200 kHz to 135 GHz at a -6 dB bandwidth, enabling it to amplify high-speed 140 Gbaud PAM4 optical signals, making it suitable for evaluating advanced optical communication systems.

In February 2025, Nokia Corporation, a Finland-based telecommunications and network infrastructure company, acquired Infinera Corporation for an undisclosed amount. Through this acquisition, Nokia aims to strengthen its position in the optical networking and transport systems industry, enhancing its capabilities in ultra-high-speed optical data transmission to support growing AI and data center demands. Infinera Corporation is a US-based manufacturer of optical transport network (OTN) hardware.
