2026 Global Optical Module Selection Guide (Website Homepage Version)
—— Explosive Growth of 800G/1.6T Technologies, Scene-Based Selection + Finisar Original Solutions in One Stop
In 2026, driven by AI computing power, optical modules have entered a critical era of rate iteration, technological restructuring, and scenario segmentation. 800G has become the mainstream for data communications, 1.6T has entered commercial deployment, and diversified routes including silicon photonics, LPO, and CPO coexist, making traditional selection logic obsolete. This article focuses on four cores: market trends, scenario-based selection, compatibility tips, and Finisar adaptation, providing practical selection solutions for enterprises, carriers, and data centers.
I. Key Optical Module Trends in 2026 (3 Highlights)
- Rate Structure: 800G (35–40 million units) dominates the market; 1.6T (8.6–25 million units) enters commercial use; 400G gradually retreats to legacy scenarios.
- Technical Routes: Silicon photonics / LPO (50% lower power consumption) for short-reach AI links; EML for long-haul transmission; NPO / CPO for high-density AI clusters.
- Mainstream Packages: SFP/SFP+ for 10G/25G; QSFP-DD for 800G/1.6T; OSFP for 1.6T+ for better heat dissipation.
II. Scenario-Based Selection List for 5 Major Industries
1. AI Data Centers / Intelligent Computing Centers
- Short-reach (<300m): 800G/1.6T silicon photonics LPO transceivers (QSFP-DD, 850nm SR8) – low power, high density
- Medium-reach (<2km): 1.6T DR4 silicon photonics modules (1310nm) – compatible with legacy networks
- Cluster pilots: NPO/CPO solutions for 10,000-card-scale deployment
2. 5G-Advanced / 6G-Ready Networks
- Fronthaul (<10km): 25G/100G CWDM4 (1271–1351nm) – cost-effective and reliable
- Midhaul / Backhaul (10–40km): 100G/400G EML modules (1550nm) – stable long-haul transmission
- Base station access: Industrial-grade SFP+ 10G LR (-40℃~85℃) – wide-temperature design
3. Enterprise Campuses / SME Networks
- Building interconnection (<500m): 10G SFP+ SR (multimode 850nm) – plug-and-play
- Campus backbone (<10km): 10G SFP+ LR (single-mode 1310nm) – wide coverage, strong compatibility
- Cost-effective upgrades: Compatible SFP+/QSFP-DD modules for Cisco, Huawei, MikroTik, etc.
4. Telecom Backbone / DCI / Metro Networks
- Metro DCI (40km): 800G ER4 (1550nm EML) – high stability for long distances
- Long-haul backbone (80–120km): Coherent optical modules (C-band/DWDM) – ultra-high capacity
- Carrier aggregation: 1.6T WDM modules – high bandwidth efficiency
5. Industrial / Medical / Special Environments
- Industrial-grade SFP/SFP+ (-40℃~85℃) – anti-interference, wide temperature, multimode/single-mode optional
