As 5G, artificial intelligence, and cloud computing continue to drive digital transformation, the demand for network bandwidth is growing at an unprecedented pace. Traditional optical communication solutions are increasingly constrained by limited fiber resources and high deployment costs. The 100G BIDI 10KM transceiver, leveraging bidirectional transmission over a single fiber, offers a compelling solution to these challenges. This article explores its core technological value, application scenarios, and future market trends—helping you stay ahead in next-generation optical networking.

Technological Breakthrough: Revolutionary Single-Fiber Bidirectional Design

The 100G BIDI 10KM module integrates PAM4 modulation and CWDM (Coarse Wavelength Division Multiplexing) to achieve 100Gbps bidirectional transmission over a single fiber, reaching distances of up to 10 kilometers. Key advantages include:

• 50% Reduction in Fiber Usage: Compared to traditional dual-fiber solutions, the single-fiber bidirectional design significantly reduces fiber requirements—ideal for metro networks and data centers where fiber is limited.

• Lower Costs: With fewer optical components (e.g., lasers and receivers), manufacturing costs can be reduced by over 40%. For instance, Eoptolink’s QSFP28 BIDI LR1 modules use silicon photonics and consume less than 3.5W, cutting operational expenses.

• Smooth Upgrade Path: These modules are interoperable with 400G transceivers (e.g., QSFP-DD DR4), enabling a seamless transition for future network upgrades.

Market Outlook: The Evolution from 100G to 400G

According to LightCounting, the global demand for 100G BIDI modules will reach 3 million units annually by 2025, making it a mainstream choice for data center upgrades. Emerging trends include:

• 400G Network Synergy: 100G BIDI modules serve as foundational units for 400G links (e.g., 4×100G PAM4), reducing the cost of scaling up.

• Adoption of Coherent Technology: Vendors like Delioptics have introduced coherent 100G BIDI modules supporting distances beyond 80km, suitable for metro WDM applications.

• Energy-Efficient Designs: New-generation modules, such as those from Lighttron, consume under 3.5W, aligning with the low-carbon goals of modern data centers.

Selection and Deployment Recommendations

• Compatibility Check: Choose modules compliant with 100G Lambda MSA and IPEC BIDI standards to ensure seamless integration with equipment from vendors like Huawei and ZTE.

• Fiber Type Matching: For multimode deployments, OM4 fiber (e.g., YOFC SuperBay OM4 Ultra) is recommended. For single-mode, use G.652.D fiber and apply dispersion compensation as needed.

• Environmental Suitability: In high-temperature or EMI-prone environments, opt for hermetically sealed modules to maintain stability. Avoid pairing short patch cords with long-reach modules to prevent optical power overload.

Conclusion

The 100G BIDI 10KM transceiver redefines cost and efficiency in optical communication through its single-fiber bidirectional design. Whether optimizing dense data center environments or expanding metro and backbone networks, this technology is driving architectures toward greater flexibility and cost-effectiveness.
