Wireless & RAN

High-reliability optical connectivity for 4G/5G, edge networks, and industrial wireless deployments

Built for Harsh Environments and Always-On Networks

Wireless and RAN networks operate at the edge - where temperature extremes, long distances, and demanding uptime requirements are the norm. Optical connectivity in these environments must remain stable, predictable, and resilient, even when deployed outdoors or in unattended sites. ATOP delivers 10G and 25G optical solutions, including CWDM and DWDM variants, engineered specifically for fronthaul, midhaul, and backhaul architectures. With industrial-temperature options and robust optical performance, ATOP enables reliable connectivity across 4G, 5G, private wireless, IoT, and Industry 4.0 deployments.

Why ATOP for Wireless & RAN

ATOP designs optics to perform consistently in the most challenging wireless environments.
Industrial-Temperature Reliability
Modules engineered for stable operation across wide temperature ranges in outdoor and edge deployments.
Fronthaul and Backhaul Optimisation
High-quality 10G and 25G CWDM/DWDM optics tailored for modern RAN architectures.
Manufacturing Consistency
Controlled production and validation ensure predictable field performance across every deployed unit.

What Wireless Networks Require

RAN and wireless transport networks must remain reliable despite environmental stress, long fiber runs, and tight power budgets.

Successful deployments depend on:

  • Wide temperature tolerance with industrial-grade options

  • Stable optical signaling for 4G and 5G fronthaul and backhaul

  • CWDM and DWDM wavelength flexibility

  • Compact, low-power modules suited to edge and outdoor sites

ATOP solutions are engineered to meet these requirements with confidence.


Compliance, Traceability & ESG Readiness

ATOP access products are supported by full production traceability and compliance documentation, including RoHS, REACH, lifecycle data, and ESG reporting where applicable.

This enables operators to meet regulatory, audit, and sustainability requirements with confidence — without retroactive data gathering or uncertainty.

Supporting You at Every Stage

From initial rollout to capacity expansion and technology transition, ATOP supports you through every phase of deployment.
