1.What is a 100G QSFP28 BIDI optical module?        By adopting the single-fiber bidirectional transmission (WDM) technology, only one fiber is needed to complete the bidirectional data transmission, saving 50% of fiber resources; with high-density design, it uses a small-sized QSFP28 package, suitable for high-density switch ports; it has strong compatibility, supporting interconnection with mainstream brand switches, and facilitating smooth upgrade of the existing network; it supports a transmission distance of 100m to 80km, applicable to solution scenarios in data centers and telecommunications operators and other fields. 2.Key technologies adopted by the 100G QSFP28 BIDI optical module        Wavelength Division Multiplexing (WDM): Traditional optical modules require two separate fibers for "sending" and "receiving". However, the BIDI module utilizes the WDM technology to enable a single fiber to carry two different wavelengths of optical signals simultaneously. For example, the upstream wavelength is 1270nm and the downstream wavelength is 1330nm. These two wavelengths do not interfere with each other, just like dividing "two-way lanes" on a highway, achieving efficient coexistence.         PAM4 modulation: The traditional NRZ modulation technology (0/1 binary level) faces a bandwidth bottleneck at high rates. However, PAM4 (four-level pulse amplitude modulation) improves efficiency through "four-lane parallelism"; each symbol carries 2 bits of information, doubling the rate compared to NRZ; it is compatible with 50Gbps single wavelength and can easily achieve a total bandwidth of 100G. 3. Advantages of 100G QSFP28 BIDI Optical Module①Half reduction in fiber resources: Single-fiber deployment saves wiring costs, especially suitable for scenarios with limited fiber resources. ②Reduce operational complexity: Decrease the number of optical fiber jumpers and lower the difficulty of troubleshooting. ③High-density energy-saving design: Low power consumption, 1U rack can accommodate more ports. ④Superb compatibility: Compatible with mainstream brand switch devices, plug-and-play. Long-distance stable transmission: Suitable for harsh environments. The 100G QSFP28 BIDI optical module redefines the cost-effective 100G transmission solution. Whether it is for data center expansion, 5G construction, or enterprise network upgrade, it can help users reduce resource investment, simplify operation and maintenance processes, and facilitate future evolution, providing a smooth transition space for the upgrade to 200G/400G. In data centers, it can meet the requirements of high-speed networks for applications such as big data transmission and cloud computing; in telecommunication networks, it can be used to build long-distance, high-speed and stable communication links, providing strong data transmission support for 4G/5G base stations and the Internet of Things, etc.

Rising Bandwidth Demands Cloud computing, artificial intelligence, and 5G networks are driving unprecedented bandwidth growth. The 100G QSFP28 ZR4 optical module meets these needs by delivering high-capacity connections over long distances. Applications in Metro and Regional Networks ZR4 modules make it possible to connect data centers across cities without the need for costly repeaters. They are ideal for metropolitan area networks (MANs), regional ISPs, and inter-campus enterprise links. Supporting Edge and Cloud Infrastructure Edge Computing: Provides low-latency connections for distributed nodes. Content Delivery Networks (CDN): Enables fast, reliable data transfer across wide areas. Telecom Operators: Strengthens backbone capacity for next-generation services. Challenges and Solutions Fiber Quality: Use premium single-mode fiber for optimal results. Device Compatibility: Ensure switches and routers support QSFP28 ZR4 standards. Environmental Control: Maintain proper cooling and dust-free data center conditions. Why ZR4 is a Future-Proof Investment By supporting 100Gbps over 80km, the LC Connector 1310nm QSFP28 ZR4 module reduces latency, simplifies architecture, and prepares networks for the demands of tomorrow. Its scalability and reliability make it indispensable for enterprises, telecoms, and cloud providers.

Check Brand and Certification When choosing a 100G ZR4 optical module, ensure it comes from a trusted manufacturer with certifications such as CE, FCC, and RoHS. Reputable suppliers also provide detailed datasheets, customer support, and warranty services. Key Technical Parameters to Verify Transmission Distance: Confirm support for 80km. Connector Type: Ensure LC duplex compatibility. Wavelength: 1310nm is the standard for ZR4. Compliance: Must meet 100GBASE-ZR4 and QSFP28 interface standards. Environmental Reliability Look for modules that can operate between 0°C and 70°C, ensuring stable performance even in varied data center conditions. DOM monitoring is also essential for real-time diagnostics. Cost and Total Ownership Value While ZR4 modules may cost more upfront than LR4 or ER4, they reduce the need for intermediate equipment, lowering total ownership costs. The investment pays off in long-term stability and reduced maintenance. Warranty and After-Sales Service A three-year warranty and responsive technical support are important. Reliable vendors also provide quick delivery and flexible minimum order quantities, making them practical for both testing and deployment.

Advantages of LC Connectors and 1310nm Wavelength The LC connector is widely used due to its compact size, easy handling, and high reliability. Paired with 1310nm wavelength operation, it ensures low signal loss over long distances, making it a cost-effective choice for 80km transmission. Comparing ZR4 with LR4 and ER4 Modules LR4 (Long Reach): Typically supports ~10km. ER4 (Extended Reach): Up to ~40km. ZR4 (Ultra Long Reach): Delivers up to 80km, doubling the distance of ER4. For businesses needing extended reach without complex repeater setups, ZR4 is the ideal solution. Hot-Swappable Design and Compatibility The 100G ZR4 module complies with QSFP28 MSA standards and is hot-swappable, allowing quick installation or replacement without shutting down the network. This makes network upgrades and maintenance much more efficient. Benefits of Single-Mode Fiber with LC Connectors Low attenuation and high performance at long distances.
