Optical Transport Network (OTN) is a key technology for building backbone fiber-optic communication networks that has replaced the synchronous digital hierarchy (SDH/SONET).

The principle of OTN technology is that signals of various formats are packed into standard containers, which are then transmitted over a fiber optic network. This ensures that any type of client signal (STM, ATM, IP, Fibre Channel, InfiniBand, etc.) can be transmitted over the transport network, as well as efficient utilization of bandwidth due to dense packaging of heterogeneous traffic.

Optical transport networks are constructed from a set of optical network elements connected by fiber-optic channels capable of providing functions such as transport, multiplexing, routing, control, monitoring and survivability of the channels over which signals are transmitted.

2023: Optical Transport Network Equipment Sales Up 2% to $16 Billion

At the end of 2023, costs in the global market for equipment for optical transport networks reached almost $16 billion. This is about 2% more compared to 2022. Industry trends are considered in a study by Dell'Oro Group, the results of which TAdviser reviewed at the end of October 2024.

It is noted that by the end of 2023, there was a decline in the market under consideration due to a decrease in demand in, and North America To Europe. Japan The main reasons were excess reserves, worsening macroeconomic conditions and higher interest rates in these regions.

North American service providers have created excess stocks after active equipment purchases in 2021 and 2022. According to our estimates, sales of products in this region rose by almost 30% over the specified period. The buildup has not had such a significant impact on the market in Europe and Japan, but the economy here is in an unstable state, says Jimmy Yu, vice president of Dell'Oro Group.

However, as noted, spending on optical equipment in China increased significantly after two years of decline, as service providers increased investments in the optical backbone network. The largest growth in market share in 2023 was demonstrated by Ciena, FiberHome and Nokia, while Cisco and Fujitsu significantly lost ground.

According to Mordor Intelligence, in 2024 the volume of the global optical transport network industry will reach $24.91 billion. Analysts believe that in the future, the CAGR (average annual growth rate in complex percentages) will be 8.41%. As a result, by 2029, costs on a global scale will rise to $37.3 billion. One of the key growth factors is the increasing demand for high-speed Internet.^[1]

2020: OTN Hardware Market Growth by 1%, to $16 Billion - Dell'Oro Group

The volume of the global market for equipment for building optical transport networks (OTN) in 2020 amounted to $16 billion, an increase of 1% compared to 2019. This is evidenced by data from the analytical company Dell'Oro Group.

According to experts, sales of such solutions increased in all regions except North and Latin America, where the decline was measured by 6% and 14%, respectively.

Optical Transport Network Equipment Market Posted Minimal Growth in 2020

In EMEA countries (Europe, Middle East, Africa), the supply of equipment for optical transport networks in monetary terms in 2020 increased by 2% compared to the previous year, in China - by 1%, in the Asia-Pacific region (excluding PRC indicators) - by 13%.

According to Jimmy Yu, vice president of Dell'Oro Group, spending on optical transport networks slowed sharply by the end of 2020 due to the fact that technologies for 5G networks began to occupy a large share in the capital expenditures of telecom operators. In addition, the situation on the market was complicated by the COVID-19 coronavirus pandemic, due to which difficulties arose with the implementation of new OTN projects^[2]
