Connector and cabling decisions involve real engineering trade-offs. Here are two common debates our customers navigate.
The choice between deploying fiber-to-the-premises and leveraging existing copper infrastructure with technologies like G.fast and VDSL2 remains a significant planning decision for network operators.
Future-proof bandwidth capacity with symmetric gigabit speeds, lower long-term maintenance costs (no active electronics in the outside plant for PON), superior latency below 1 ms, and reliability advantages for next-generation applications including cloud gaming and remote surgery.
Significantly lower upfront deployment cost by reusing existing copper pairs, faster rollout timelines (weeks vs. months for civil works), and sufficient bandwidth for current demand — G.fast delivers up to 1 Gbps over distances under 250 m, which covers many last-mile scenarios.
The right choice depends on projected bandwidth demand growth, existing infrastructure condition, regulatory incentives, and deployment timeline constraints. Many operators adopt a phased approach: G.fast for immediate coverage, fiber overbuild for high-demand areas.
Selecting between AON and PON architectures involves balancing per-user bandwidth, operational costs, and deployment economics.
Dedicated bandwidth per subscriber (no sharing), longer reach up to 80 km without amplification, easier per-port troubleshooting and traffic monitoring, and simpler capacity planning since each user has a dedicated wavelength or fiber.
Lower operational costs with no powered equipment in the field (passive splitters only), simpler outside plant maintenance, better cost economics for high-density residential deployments (1:32 or 1:64 split ratios), and evolving standards like 25G-PON and 50G-PON narrowing the bandwidth gap.
Enterprise campus networks often favor AON for dedicated bandwidth guarantees, while residential FTTH deployments predominantly use GPON or XGS-PON for cost efficiency. Connector requirements differ: AON typically uses more SC/APC connections per subscriber, while PON requires high-quality splitter-grade connectors with insertion loss below 0.15 dB.
