2.5Gbps APD-TIA TO-CAN Comparison: MACOM vs Agiltron vs Wuhan Siyou

Brief Overview of APD-TIA TO-CAN in Optical Communication

The 2.5Gbps APD-TIA TO-CAN is a high-performance optical receiver component that combines an InGaAs Avalanche Photodiode (APD) with a Transimpedance Amplifier (TIA) in a compact TO-CAN package. This integration delivers high sensitivity, low noise, and strong signal amplification, making it ideal for fiber optic applications such as metro networks, data center interconnects, PON systems, and regional transmission links.

In this objective comparison, we look at offerings from three suppliers: MACOM (global leader in photonic solutions), Agiltron (specialist in high-speed fiber-coupled detectors), and Wuhan Siyou Photoelectric Technology (focused on cost-effective, integrated TO-CAN receivers). Each brings distinct strengths to help you find the right fit.

MACOM Advantages: Proven Reliability and Advanced Features

MACOM is a trusted name in the industry, known for high-quality TIAs and APD-compatible solutions used in telecom and datacom systems.

Key highlights:

• Strong focus on burst-mode performance, which is especially valuable for PON applications.
• Excellent dynamic range and low-noise design for consistent operation in demanding environments.
• Long-term supply reliability, global support, and compliance with rigorous industry standards.

MACOM products are a solid choice when maximum uptime and proven performance are priorities.

Agiltron Advantages: Flexibility and Future-Proof Design

Agiltron offers fiber-coupled InGaAs APD photodiodes integrated with high-speed TIAs, designed for versatility across multiple data rates.

Key highlights:

• Support for a wide range of speeds (from 2.5Gbps up to 25Gbps in the same family), enabling easier upgrades without hardware changes.
• Fiber-coupled architecture with differential output for better signal integrity and simplified integration.
• High bandwidth suitable for both current and emerging optical systems.

Agiltron stands out for projects that value adaptability and forward compatibility.

Wuhan Siyou Advantages: Outstanding Value and Practical Performance

Wuhan Siyou Photoelectric Technology delivers a dedicated 2.5Gbps APD-TIA TO-CAN series optimized for real-world efficiency and affordability.

Key highlights:

• High typical sensitivity around -33 dBm, with built-in RSSI for convenient real-time monitoring.
• Wide industrial temperature range (-40°C to +85°C) and low power consumption (single +3.3V supply, ~34 mA typical).
• Compact TO-CAN packaging with differential output, plus fast lead times, stable supply, and strong customization options as a specialized China-based manufacturer.

Wuhan Siyou provides excellent performance-to-cost ratio, making it particularly attractive for high-volume deployments, metro networks, and budget-conscious projects where core specifications are met without premium overhead.

Price and Supply Chain Considerations

MACOM generally sits at the higher end due to its brand reputation and extensive support ecosystem. Agiltron offers a balanced mid-to-high positioning with added flexibility. Wuhan Siyou stands out for superior value — competitive pricing, shorter delivery times, and easier OEM customization, especially advantageous for Asia-Pacific or large-scale sourcing.

When evaluating total cost, factor in volume, lead time, and long-term availability alongside upfront specs.

No single supplier is universally "best" — the right choice depends on your project's specific balance of performance, budget, timeline, and future requirements.
