Technical Trade-Offs to Consider

Infrastructure decisions involve trade-offs. Here are two common ones our customers navigate.

Trade-Off

Passive Optical Networks (PON) vs. Active Optical Networks (AON)

PON (GPON / XGS-PON): Uses unpowered splitters in the field, reducing operational costs and simplifying outside plant maintenance. Economics favor high-density residential FTTH deployments where bandwidth can be shared across 32 or 64 subscribers per OLT port.

AON (Point-to-Point): Requires powered equipment at each split point, but provides dedicated bandwidth per subscriber and supports longer reach distances — up to 80 km without repeaters. Easier to isolate faults with OTDR testing on individual fibers.

Our take: Neither architecture is universally superior. PON suits dense residential areas where per-subscriber cost matters most. AON suits enterprise and campus networks where dedicated bandwidth and simpler troubleshooting justify the higher infrastructure cost. Many operators deploy both — PON for residential and AON for business services — and our distribution cabinets support either architecture.

Trade-Off

5G mmWave vs. Sub-6 GHz Deployment Strategy

mmWave (24-40 GHz): Delivers massive bandwidth — up to 800 MHz channel widths — and ultra-low latency below 1 ms. Ideal for dense urban venues, stadiums, and industrial IoT applications. However, signal propagation is limited to approximately 200-300 meters, and penetration through walls and foliage is poor, requiring significantly higher site density.

Sub-6 GHz (600 MHz - 6 GHz): Offers wider coverage per cell site — 1 to 3 km in urban areas — with better building penetration. More cost-effective for nationwide coverage rollouts, though peak throughput is lower (typically 100-400 Mbps per user).

Our take: Most operators pursue a layered strategy: sub-6 GHz for broad coverage and mmWave for capacity hotspots. The choice directly affects cabinet requirements — mmWave deployments need more compact, street-level enclosures at higher density, while sub-6 GHz relies on traditional macro site cabinets. We supply enclosures optimized for both deployment models.

Frequently Asked Questions

IP55 provides protection against dust ingress (limited) and low-pressure water jets from any direction. IP65 is fully dust-tight and protects against low-pressure water jets. For most outdoor telecom deployments, IP55 is sufficient; IP65 is recommended for coastal or wash-down environments.

Add up the heat dissipation (in Watts) of all equipment inside the cabinet, then factor in solar heat gain for outdoor installations (typically 200-400W additional). The total gives you the minimum cooling capacity needed. Our engineers can help you run the calculation — just send us your equipment list.

Yes. We offer single-unit samples for standard products and small pilot runs (5-10 units) for custom configurations. Contact our sales team to arrange a sample order.

Select models in our telecom cabinet line are NEBS Level 3 compliant per Telcordia GR-63-CORE (seismic, thermal, airborne contaminants) and GR-487-CORE (outside plant). Please specify NEBS requirements when requesting a quote so we can recommend compliant models.
