Do not insert the module into a port with a mismatched wavelength. When inserting a coherent optical module into a switch, make sure that its total power consumption is within the rated power capacity of the switch port. As a general practice, fully populating all ports with high-power modules is not recommended, as it may negatively impact heat dissipation. 2. Safety Risk Notification 2.1 Precautions Icon Text Description image.png Keep dry image.png Do not disassemble or modify image.png Please wear anti-static gloves image.png Do not look into fiber ports image.png The module may only be installed or replaced by qualified personnel The theoretical mating cycle limit for optical modules typically ranges from 500 to 2000 insertions. Frequent removal and reinsertion of 100G/400G coherent optical modules can reduce their service life. Therefore, such operations should be avoided unless absolutely necessary. Before installing or removing a 100G/400G coherent optical module, always disconnect all fiber patch cables. Never install or remove the module while the fiber is still connected, as this may cause damage to the patch cables or the module itself, potentially degrading transmission performance. After removing the fiber, protect the pluggable module by inserting a clean dust cap. Before reconnecting the fiber to another 100G/400G coherent module, ensure that the optical surface of the fiber is properly cleaned. Prevent dust or other contaminants from entering the optical port of the module, as contamination can impair the performance of optical components. Coherent optical modules are highly sensitive to electrostatic discharge (ESD). Always use an ESD wrist strap or equivalent grounding device/anti-static gloves during the installation or removal process to avoid damage. When interconnecting two coherent optical modules, it is recommended to use the same model of 100G/400G coherent modules on both ends to ensure compatibility and optimal performance. 2.1.1 ESD Prevention Measures[1] Note: Optical modules are electrostatic discharge (ESD) sensitive devices. Always use an ESD wrist strap or a similar individually grounded device when handling or touching the module. Optical modules are susceptible to electrostatic discharge (ESD), which can damage sensitive integrated circuits. Personnel handling the modules should wear ESD-protective wrist straps that are properly grounded. Work surfaces and benches should also be ESD-protected and connected to a common grounding point. 2.2 Operating Temperature of the Optical Module To ensure the long-term stability and reliable performance of optical modules, it is essential to operate them within the specified temperature range. Regular monitoring of the module’s operating status and maintaining adequate system cooling can significantly extend the module’s service life. The operating temperature range is typically defined by the manufacturer and generally falls into two categories: Commercial grade: 0°C to 70°C Industrial grade: -40°C to 85°C The effects of too high or too low temperature on the optical module are as follows: High Temperature Effects Signal attenuation: Elevated temperatures can increase signal loss, degrading optical transmission quality and potentially causing data errors. Component aging: High temperatures accelerate the aging of internal electronic components, reducing the module’s overall lifespan. Increased failure risk: Excessive heat can impair the performance of the transmitter and receiver, potentially leading to module failure or permanent damage. Low Temperature Effects Startup issues: At excessively low temperatures, optical modules may fail to start or operate correctly, especially outside the industrial-grade range. Unstable optical power: Low temperatures may cause instability in the laser’s output power, which can affect data transmission performance. To ensure reliable performance, optical modules must operate within their specified temperature range. Operating outside of this range may lead to performance degradation or even permanent damage to the module. Several factors influence the module’s case and surface temperature, including the ambient temperature of the operating environment, airflow, cage design, and heat sink integration. All of these contribute to the thermal behavior of the module. When physically removing a module from a port, it should only be done when the module has cooled down to a comfortable handling temperature. Typically, the case temperature of an optical module is approximately 10 to 15°C higher than the ambient temperature. For example, in a 45°C environment, the case temperature can easily reach 60°C or higher, making the metal housing hotter than recommended handling limits. These modules are designed to dissipate heat efficiently through conduction via the host platform’s cage and any attached heat sink, provided that adequate airflow is maintained. 3. Installing 100G/400G Coherent Optical Modules 3.1 Install/Replace Optical Module[2] Note: QSFP-DD ports can usually use QSFP-DD/QSFP28 optical modules, while QSFP28 ports cannot use QSFP-DD optical modules. To install an optical module, follow these steps: 1. Wear an ESD wrist strap and ensure it is properly grounded to the chassis or rack ground point. 2. Remove the optical module from its protective packaging. 3. Check the label on the body of the 100G/400G coherent optical module to verify that the module model matches your network requirements. 4. Hold the module with the identifier label facing downward. Align the module with the front of the platform port, and carefully slide it into the socket until it makes contact with the electrical connector. On some platforms, the cages for 100G/400G coherent modules are mounted upside down. In such cases, the identifier label must face upward during insertion. (As shown in Figures 3 to 4) Figure 3 Install 100G Coherent QSFP28 Transceiver Module 1-1.jpg Figure 4 Install 100G Coherent QSFP28 Transceiver Module 1-2.jpg 5. Firmly press the front end of the optical module with your thumb to ensure it is fully seated in the QSFP28/QSFP-DD cage. If the latch is not fully engaged, the 100G/400G coherent optical module may become accidentally disconnected. 6. Do not remove the dust cap until you are ready to connect the fiber. 7. Always clean the fiber connector end face using an appropriate fiber cleaning tool. This step should be performed every time before inserting the fiber into the module’s optical receptacle. 3.2 Install/Replace Fiber Optic Patch Cables 1. Verify that the labels on the fiber patch cords are correct, legible, and neatly applied. If any label is unclear or difficult to identify, it should be replaced to avoid connection errors. 2. Check the condition of the fiber connection. Before removal, ensure that the patch cord is properly connected and free from bending or other physical damage. 3. When removing the fiber patch cord (e.g., replacing an LC patch cord), wear anti-static gloves. Use the index finger and thumb of one hand to hold both sides of the 100G/400G coherent optical module firmly. With the other hand, use your index finger and thumb to grip both sides of the LC connector, keeping the patch cord in a horizontal position (avoid angling or twisting). Gently pull the LC connector straight back with light force. (Do not pull on the fiber itself. Remove the connector gradually to avoid applying excessive stress to the fiber.) Figure 5 Duplex LC fiber installation 2-1.jpg 4. After removing the fiber patch cord, remove the dust cap from the new fiber patch cord. Hold the new fiber connector body with your index finger and thumb on both sides, align the key on the connector with the keyway on the optical module, and insert the fiber patch cord horizontally (avoid angling) into the module until the locking mechanism clicks into place. Ensure the connector is clean before insertion. 5. Once the link is fully established, the LED indicator will light solid green. 6. After replacing the fiber patch cord, store the old fiber patch cord in an anti-static packaging. 4. Removing 100G/400G Coherent Optical Module 4.1 Remove Optical Module[3] Note: The form-factor pluggable 100G/400G coherent optical modules are designed with a pull-tab release mechanism. To remove the optical module, follow these steps using the pull-tab: 1. Wear an ESD wrist strap and ensure it is properly grounded to the chassis or rack ground point. 2. Disconnect the fiber connector from the optical module. Keep the fiber connector clean. 3. For modules equipped with a pull-tab latch: Immediately insert a dust cap into the optical port of the module. Grasp the label with your fingers and gently pull the pull-tab to release the module from the socket. Slide the module out of the socket by holding the pull-tab only; avoid touching the pluggable metal surfaces. 4. Place the module on an ESD-safe workstation or work area and allow it to cool down before placing it into an anti-static bag. Figure 6 Removing QSFP28 Transceiver Modules 3-1.jpg 5. Cleaning and Maintenance 5.1 End Face Treatment and Cleaning Optical modules can be damaged by exposure to current surges and overvoltage events. Please ensure that exposure is limited within the conditions defined by the absolute maximum ratings. Always follow standard electrostatic discharge (ESD) precautions for handling sensitive devices. Optical modules are equipped with dust caps on both the electrical and optical ports. When fibers are not connected, dust caps on the optical ports should always be kept in place. The fiber connector has a recessed connector end face, which becomes exposed when neither fiber nor dust cap is present. Important Note 1: Always keep the dust caps for both fiber connectors and optical modules. Important Note 2: Before inserting the fiber, clean both the module end face and the fiber patch cord end face thoroughly to prevent contamination. Dust caps help maintain the cleanliness of optical components during transportation. Standard cleaning tools and methods should be used during installation and maintenance. The use of liquids is prohibited. Important Note 3: Approximately 80% of optical module link issues are related to dirty fiber connectors. Figure 7 Module End-Face Inspection image.png Figure 8 Module End-Face Cleaning 4-1.jpg 5.2 Maintain Fiber Optic Jumpers[4] Fiber Patch Cord Maintenance: When unplugging the fiber from the optical module, place rubber protective caps on both the module port and the fiber end face. Secure the fiber to avoid stress on the connector. When connecting the fiber to the module, make sure the fiber is supported so that its own weight does not hang freely from the connector. Never allow the fiber to dangle unsupported from the connector. Do not bend the fiber beyond its minimum bend radius. Exceeding the minimum bend radius may damage the fiber and cause difficult-to-diagnose problems. Frequent plugging and unplugging of fibers into optical instruments can damage the instruments and incur high repair costs. Use a short fiber extender cable connected to the optical device. Any wear caused by frequent mating cycles will be absorbed by the extender cable, which is easier and less expensive to replace than the instrument itself. Keep fiber connections clean. Tiny deposits of oil and dust inside the optical module or fiber connector ferrules can cause optical loss, reduced signal power, and intermittent connection issues. To clean the optical module receptacle, use appropriate fiber cleaning tools such as the ATC-NS-125 Fiber Adapter Cleaning Stick (Part No. 190742). Follow the instructions provided with your cleaning kit. After cleaning the optical module, ensure the fiber connector end face is clean. Only use approved alcohol-free fiber cleaning kits, such as the Cletop-S® Fiber Cleaner. Follow the instructions provided with your cleaning kit.

Common Issue Troubleshooting 8.1 Optical Module Insertion and Removal Issues 8.1.1 Optical Module Latch Issues Issues with optical module latches may include poor physical connection, interface mismatch, or difficulty during insertion and removal. Addressing these problems requires a comprehensive approach considering hardware design, connectors, and protocols. Below are some suggested solutions for common optical module latch issues: ①Locate the module’s release mechanism; The unlocking position of 100G/400G coherent optical modules is generally on the left and right sides of the module. ②Insert a pair of tweezers or a stainless steel card between the module latch and the switch cage, then apply horizontal force to gradually pull the module out. ③Be careful during this process to avoid scratching the module or damaging the switch port. 8.1.2 Optical Module Installation Issues Pre-installation Inspection: Check the gold fingers of the optical module to ensure they are clean and shiny. Inspect the device ports for any physical damage. Examine the optical module’s port interface to confirm there are no visible damages. Verify that the ferrules of the patch cords are not damaged. Installation issues may arise from various factors including physical connection, connectors, and device compatibility. Below are common problems and recommended solutions: 1. Optical Module Installation Issue: Problem: The optical module is not fully seated in the device slot, causing damage to the device port or the module itself. Solution: When inserting the module, ensure it is firmly pushed into the slot and the latch engages properly. Align the module connector correctly and gently push it into the slot. A “click” sound indicates proper insertion and that the locking mechanism is engaged. Without this, vibration or shocks may cause disconnection or loosening. 2. Optical Module Installation Issue: Problem: The LC patch cord is not properly inserted into the optical module, causing damage to the module port or the patch cord. Solution: When installing the LC patch cord, hold the connector body with your index finger and thumb on both sides, align the key on the connector with the keyway on the optical module, and insert the patch cord horizontally (do not angle it) until the locking mechanism clicks. 8.2 Optical Module (Patch Cord, Adapter) End-Face Contamination Issues Contamination of the optical module end-face is a common issue that adversely affects optical communication performance. Below are some recommendations for handling end-face contamination: 1. Proper Use of Inspection and Cleaning Tools: Use end-face inspection microscopes, LC cleaning pens, and other appropriate tools to inspect and clean the connector end-faces of optical modules and fiber patch cords. Inspection tools provide a clearer view of microscopic contamination and defects on the connector end-face. 2. Environmental Control: Ensure the connection and storage environment for fiber connectors is kept clean. Avoid performing connection operations in environments with excessive dust, smoke, or other contaminants. 3. Regular Cleaning: Clean the optical module and LC patch cord end-faces regularly, especially before plugging or unplugging the modules or patch cords. 4. Avoid Touching Connector End-Faces: Do not touch connector end-faces directly during handling. Always wear an ESD wrist strap connected to a proper ground point or wear anti-static gloves. 5. Use Dust Caps: When optical modules or LC patch cords are not in use, protect the connector end-faces with the appropriate dust caps to prevent contamination. 6. Proper Storage: Store optical modules in a dry, clean environment, away from dust and humidity. 7. Operator Training: Train personnel on proper handling and maintenance of optical modules and LC patch cords to ensure all operators understand how to maintain clean connector end-faces effectively. When addressing end-face contamination, always refer to the relevant device and connector operation manuals, and follow the product compatibility recommendations and specifications. 8.3 Optical Module Detector Breakdown and Saturation Issues 8.3.1 Detector Breakdown Issue Detector breakdown: when the optical module’s detector is exposed to excessively strong optical signals, causing it to malfunction or produce unstable output signals. Solutions: Reduce optical input power: If the detector receives an excessively strong signal, reduce the input power by using an appropriately rated optical attenuator or by increasing the transmission distance. Replace the module: If the detector has already been damaged by breakdown, the module must be replaced with a new one. 8.3.2 Detector Saturation Issue Detector saturation: when the detector’s output signal becomes saturated due to strong input optical signals, meaning the output no longer accurately reflects variations in the input signal power. Solutions: Reduce optical input power: Saturation is usually caused by excessively strong optical signals; reducing input power via an optical attenuator or increasing transmission distance can alleviate the problem. Use linear output detectors: Some optical modules employ detectors with linear output characteristics, where the output signal is proportional to the input optical power, providing more accurate signal measurement and reducing saturation issues.
