As broadband networks continue to evolve, service providers are facing growing demand for higher capacity and more efficient use of their existing infrastructure. The push toward symmetrical multi-gigabit services, remote PHY deployments, and 10G PON architectures has driven operators to maximize the potential of their fiber networks without costly rebuilds.
Where it’s deployed, fiber capacity can be significantly expanded through Dense Wave Division Multiplexing (DWDM) solutions that eliminate the need to place additional fiber. These systems save both time and capital while enabling faster response to growing bandwidth demand from residential, business, and mobile backhaul services.
However, distribution networks can still be limited by the capacity of their outside plant (OSP) splice closures—particularly those that are near or have already reached exhaust. Adding a new closure for every capacity upgrade represents a substantial investment in both placement and splicing labor.
Amphenol has addressed this challenge with its innovative OptiFi™ AOM (Advanced Optical Module), a next-generation DWDM solution designed to handle high channel counts within the footprint of existing OSP closures. By maximizing density and utilizing unused space within the closure, the OptiFi AOM helps operators expand fiber capacity without the need for new closures—saving significant time and cost.
The OptiFi AOM builds upon the proven OptiFi HiDT xWDM packaging, offering solutions from 4 to 48 channels in a compact, ruggedized form factor. The smaller HiDT modules serve lower-count applications (10 channels or fewer), while the OptiFi AOM provides the flexibility to scale up to 48 channels with stable optical performance across the full operating temperature range required for OSP deployment.
To ensure reliable and repeatable installation, Amphenol provides a comprehensive accessory system that allows the OptiFi AOM to be securely mounted inside a variety of industry-standard OSP closures. Unlike makeshift solutions using Velcro or tape, the OptiFi AOM mounts directly into the closure’s tray tower via a tray and hinge allowing it to articulate up and down with the splice trays. This robust mechanical mounting ensures the module remains secure even through temperature fluctuations or multiple closure re-entries. This level of mechanical security reduces the likelihood of service-affecting disturbances, contributing to long-term operational savings.
Installation versatility is another key feature. The OptiFi AOM can be mounted in two common locations within many standard closures:
- In the splice tray stack: The module is snap-mounted into a bracket that attaches to the closure’s tray tower, consuming a single tray position.
- In the slack basket: In some closures, the module can be installed in the slack storage area, utilizing unused tower positions without disrupting buffer tube storage. Up to two OptiFi AOMs can be added using this approach, significantly increasing closure capacity without occupying any tower positions used for splice trays.
In addition, the OptiFi AOM provides conveniently located test ports at the most accessible end of the closure—eliminating the need to disturb splice trays or internal fiber routing during testing and troubleshooting. This accessibility streamlines maintenance and reduces operational expenses.
Industry Context: Expanding Optical Capacity for Modern Networks
Since the introduction of the original OSP AOM, the broadband landscape has evolved dramatically. The rollout of 10G and 25G PON, the advent of fiber deep architectures, and the ongoing migration to converged access networks have intensified the need for modular, space-efficient DWDM solutions. At the same time, fiber consolidation and remote node densification have made it more important than ever to extract maximum capacity from existing closures.
The OptiFi AOM aligns perfectly with this industry shift—enabling operators to efficiently scale optical capacity in support of new technologies such as FTTH expansion, 5G fronthaul/midhaul, and cloud edge connectivity. Its compact, field-friendly design empowers service providers to meet future bandwidth demands without disruptive rebuilds or excessive CAPEX.
Summary
The OptiFi AOM from Amphenol offers a simple, reliable, and cost-effective method to expand fiber network capacity using embedded OSP infrastructure. By leveraging unused closure space, providing secure mechanical mounting, and simplifying field testing, the OptiFi AOM ensures that operators can scale network capacity in step with next-generation service demands—without compromise.
