Traditionally, the C-band has dominated long-haul transmission. However, for DCI “last-mile” applications spanning 2 km to 30 km, its cost structure is increasingly difficult to justify. FIBERSTAMP’s O-band (1310 nm) DWDM technology, with its naturally low-dispersion transmission window, establishes a new benchmark for cost-efficient 400GE data center interconnects.

400G QSFP-DD PSM DWDM4 Optical Module

Key Advantages:

DCM-Free Operation: Operating within the O-band’s low-dispersion window eliminates the need for bulky and costly dispersion compensation modules (DCM), simplifying line card design while reducing insertion loss.

Ultra-Low Power Consumption: Advanced silicon photonics integration enables industry-leading power efficiency, making the solution ideal for high-density data center deployments.

Cost-Optimized Architecture: For short- to mid-reach DCI applications, the solution avoids the complexity of coherent C-band transceivers, providing a high-performance direct-detect architecture that significantly reduces CapEx.

Ultra-Low Latency: By eliminating DSP-based dispersion compensation required in coherent optics, the module greatly reduces optical transmission latency, enabling faster data center interconnect performance.

FIBERSTAMP HYBRID Architecture Patent Overview

HYBRID Architecture: Advantages and Key Considerations

1. Key Advantages of HYBRID

Significant Power Reduction:

Approximately 20–30% lower power consumption compared with full-DSP solutions

Ultra-low Link Latency:

With only half the DSP processing, latency is reduced by approximately 50%, approaching performance levels similar to LRO architectures.

Reliable Signal Quality:

• Multimode 50 m: PRE-FEC BER E-7 / E-8
• Single-mode 500 m: PRE-FEC BER E-10

Optimized Cost Structure:

2. Limitations and Engineering Considerations

Non-DSP receiver channels require slightly tighter host-side SI tuning.

System-level co-optimization is required rather than simple plug-and-play deployment

Large-scale commercialization is still in its early stage and requires close collaboration with ecosystem partners.

Nevertheless, compared with LPO and LRO architectures, the engineering risks associated with the HYBRID architecture are significantly more manageable.

Advancing Next-Generation Optical Interconnects

Powering the Future of AI and Data Center Infrastructure

The 2026 Lightwave Innovation Award recognition reinforces FIBERSTAMP’s commitment to advancing HYBRID interconnect architectures and silicon photonics technologies. By optimizing DSP architecture, energy efficiency, and system design, FIBERSTAMP continues to enable scalable, low-latency, and cost-effective connectivity solutions for global data centers and AI infrastructure.

The post FIBERSTAMP Wins 2026 Lightwave Innovation Award — HYBRID 800G ACC+, 800G AOC, and 1.6T Silicon Photonics Active Optical Cables Honored first appeared on FIBERSTAMP.

Product 1: 800G OSFP HYBRID ACC+ Active Copper Cable

The 800G OSFP HYBRID ACC+ Active Copper Cable is built on a HYBRID half-DSP architecture, in which DSP-based signal compensation is implemented on only one side of the link—either the host side or the line side. This design maintains high-speed signal integrity and link stability while significantly reducing power consumption, link latency, and overall system cost.

The product was characterized and tuned using FIBERSTAMP’s in-house checker test platform and was successfully validated on an NVIDIA 800G InfiniBand switch platform. Test results confirm full compatibility with 800G switch ports at a transmission distance of 5 meters, with the following performance metrics:

• Data Rate: 800 Gbps (8 × 100G)
• Maximum Reach: ≥ 5 meters
• Typical Power Consumption: ~5.5 W per end
• Link Latency (5 m): ~100 ns
• Pre-FEC BER: Stable at the 1E-9 level
• Post-FEC BER: Up to 1E-15 or better
• Eye Opening Info FOM: Majority of channels above 70

Compared with conventional AEC solutions under equivalent transmission conditions, HYBRID ACC+ delivers approximately 40% improvement in power efficiency, latency, and cost, providing a high-performance and cost-effective short-reach interconnect option for high-density data center deployments.

As the HYBRID solution adopts a half-DSP architecture, achieving optimal system-level performance typically requires joint tuning and validation with original equipment manufacturers (OEMs) during deployment.

Product 2: 800G OSFP-PHO 2×DR4 Silicon Photonics Module Based on HYBRID Architecture

FIBERSTAMP also showcases its 800G OSFP-PHO 2×DR4 silicon photonics module, designed on the HYBRID architecture. The module supports configurations from 800G OSFP112-PHO 2×DR4 to 2 × 400G DR4 (QSFP112 / OSFP-RHS), addressing 500-meter-class short- to mid-reach optical interconnect requirements in data center environments.

Key technical features include:

• Module Power Consumption: < 12.5 W, approximately 20% lower than traditional full-DSP optical modules.
• Transmission Reach: Up to 500 meters over single-mode fiber (SMF) with KP4-FEC enabled.
• Link Latency :  Approximately 50% lower than conventional DSP-based architectures.
• Signal Quality: Pre-FEC BER reaching the E-10 level.

High-Temperature Fiber Transmission BER

Experimental results demonstrate that HYBRID half-DSP technology can effectively compensate for channel loss, making high-performance, cost-efficient 800G optical interconnect upgrades technically feasible for hyperscale data centers and cloud service providers.

Under the current LRO operating mode, the receiver link still exhibits a limited post-correction symbol margin (slightly above 10), which requires collaborative system-level tuning with OEM partners to further optimize end-to-end link performance.
