Service providers have invested in expanding their on-net fiber infrastructure to deliver differentiated services and improve customer experience. The demand for high-quality business internet and data center connectivity has further fueled adoption of on-net solutions.
Additionally, on-net connectivity enables providers to reduce operational costs by leveraging owned assets rather than leasing third-party networks. As enterprises increasingly require dedicated and secure connections, on-net connectivity is poised to remain a key growth driver.
The IT & Telecommunication segment is projected to account for 47.9% of the lit fiber market revenue in 2025, maintaining its dominant role in applications. This sector demands high-capacity and low-latency networks to support data centers, cloud services, and communication infrastructure.
The rapid expansion of digital services and the growing number of internet users have intensified the need for fiber-based networks. Network upgrades, including 5G backhaul and enterprise connectivity solutions, have driven fiber deployments.
Furthermore, the sector’s focus on reliability and scalability has made lit fiber a preferred choice for mission-critical applications. As digital transformation accelerates globally, the IT & Telecommunication segment will continue to lead demand for lit fiber infrastructure.
Governments around the world have adopted this lit fiber technology to provide a foundation for digitalapplications pertaining to community safety and establishment of smart cities, bygivingtheir citizens strong internetconnectivity for accessing e-government services.
A rapid gush in the sales of lit fiber was observed in the recent past, owing to its higher adoption by gaming and entertainmentfirms for video game players.
High implementation cost of advanced lit fiber technology is regarded as the major hindrance for the target market growth. Moreover, many establishments prefer to continue with the pre-existing conventional fiber optics network that could pose as a major challenge for the sales of the lit fiber in the regional markets.
In the coming days, with the better awareness about the several advantages available with the modern lit fiber connections the lit fiber manufacturers are anticipated to overcome these obstructions against their magnification.
As per the new research report on lit fiber market for years 2025 to 2035, the multi-mode segment, which also accounted for the highest revenue share in the year 2024, is again anticipated to grow at a CAGR of about 16.3%. The global popularity of this segment of multi-mode lit fiber is growing because it has a bigger core and is more affordable that can be deployed for connections of more than 400 meters.
Moreover, these multi-mode wires are contributing significantly to the present day lit fiber market key trends as these are perfect for use in a data center for utilizing less power than single-mode. With more dispersion but less brightness, numerous information beams can be transmitted concurrently at lower overall expense. Other than that, the major network professionals can swiftly deploy and remove multi-mode fiber cables, while upgrading a network across a building.
The single-mode category, but from the other end, is anticipated to expand at a quicker CAGR of nearly 17.2% as evident from the lit fiber market statistics report. Compared to multi-mode fiber, single-mode lit fiber has a smaller core, making it suitable for several other areas of application. For long-distance deployments it has a 9 m optical core, enabling greater bandwidth usage as well as extended delivery distances
With a higher CAGR of 17% recorded by the lit fiber market survey report for the historical period 2020 to 2024, the on-net category outgrew all other market segments during that time. On-net lit fiber connection is provided by an operator that is the owner of the network infrastructure present at a specific spot.
Using the hardware set up in a nearby BT exchange, the carrier establishes a connection to the telecom service providers' network. Since the carrier network's cables are really present in the vicinity, these interconnections become more affordable over off-net connections rendering it as the dominant segment of the global lit fiber market.
Over the planning horizon of this lit fiber market analysis report, the off-net category is anticipated to have significant expansion as it mostly consists of a solution provider who rents an extended connection at a local wireless facility.
Also therefore, every off-net lit fiber connection includes unintended and far-off factors that might impair the network's connectivity and service quality. This also makes updates and solutions to out-of-service situations more difficult limiting the popularity of this global lit fiber market segment.
Until the end of the year 2024, as per the global market study on lit fiber, the networking category had the highest revenue share of 31.7%.
Attributed to the increasing use of information technology in data transfer and communication services, the telecommunications sector is expected to experience significant development. Greater data transfer via short- and long-distance communications is made possible by fiber optics.
Furthermore, it is anticipated that the growing demand for cloud-based apps, multimedia communications, and livestreaming platforms and other websites services would fuel the expansion of the telecommunications segment of the global lit fiber market.
According to broad geographical regions,North America, which had a 28% sales share by the end of year 2024, is expected to maintain its dominance throughout the projection timeframe. An advanced foundation in this area makes it simpler to construct illuminated fiber links across United Statesthat has settled USA lit fiber market as the most lucrative segment for the target product.
As evident from the recent developments in lit fiber market during the predicted period, Asia Pacific is probably going to surpass Europe as the next most promising area.
The reasons driving the Asia Pacific lit fiber market growth in the coming years include the expansion of technology and its widespread acceptance in the information technology, telecommunications, and organizational sectors. Secondly, the Asia Pacific market is strengthened by the extensive use of such cables in parallel with the acceleratingindustrial, aerospace, and defense sectors in the several of the economies.
