2. Problems that may be encountered during transmission

2.1 Signal attenuation and loss

Signal attenuation and loss are one of the most common problems of QSFP+ to QSFP+ 40G AOC during transmission. Since the optical cable will be affected by fiber loss, connector loss and environmental factors during transmission, the signal strength will gradually weaken, thus affecting the transmission quality and stability.

Solution:

Choose high-quality optical cables and connectors: High-quality optical cables and connectors have lower loss and better transmission performance, which can effectively reduce signal attenuation.

Optimize the layout of optical cables: Rationally plan the direction and length of optical cables, avoid too long optical cables and too many bends to reduce signal loss.

Use optical amplifiers or repeaters: In the case of long transmission distances or large signal loss, you can consider using optical amplifiers or repeaters to enhance signal strength.

2.2 Electromagnetic interference (EMI)

Although QSFP+ to QSFP+ 40G AOC itself has the ability to resist electromagnetic interference, it may still be affected by electromagnetic interference in some special environments, such as areas with strong electromagnetic fields, resulting in reduced transmission performance.

Solution:

Choose optical cables with good shielding performance: Shielded optical cables can effectively reduce the impact of electromagnetic interference on transmission signals.

Optimize the wiring environment: Try to avoid arranging optical cables in areas with strong electromagnetic interference, such as near high-voltage wires or large motors.

Use anti-electromagnetic interference connectors: Choose connectors with anti-electromagnetic interference functions, such as connectors with metal shells, to enhance the anti-electromagnetic interference ability of optical cables.

2.3 Connector loose or damaged

QSFP+ connectors may become loose or damaged during long-term use due to excessive plugging and unplugging, vibration or external force impact, thereby affecting transmission performance.

Solution:

Check the connector status regularly: Check the QSFP+ connector regularly to ensure that it is tight and not damaged.

Use high-quality connectors: High-quality connectors have better durability and stability, which can reduce the risk of looseness and damage.

Plug and unplug connectors correctly: When plugging and unplugging connectors, ensure that the operation is standardized and the force is moderate to avoid excessive force or improper operation that may cause damage to the connector.

2.4 Fiber breakage or excessive bending

Fiber may break during transmission due to external force squeezing, excessive bending or long-term use, thereby affecting transmission performance.

Solution:

Avoid excessive bending: When laying optical cables, avoid excessive bending of optical fibers to avoid damaging the optical fiber structure.

Use optical fiber protective sleeves: In areas where optical fibers are easily squeezed or rubbed by external forces, optical fiber protective sleeves can be used to enhance the durability of optical fibers.

Check the optical fiber status regularly: Check the optical fiber regularly to ensure that it is not broken or damaged.

2.5 Temperature and humidity effects

Temperature and humidity are important factors affecting the transmission performance of optical cables. Too high or too low temperature and excessive humidity may cause the performance of optical cables to deteriorate.

Solution:

Control ambient temperature and humidity: In application scenarios such as data centers, ensure that the ambient temperature and humidity are controlled within an appropriate range to avoid adverse effects on the performance of optical cables.

Use high temperature and moisture-proof optical cables: In high temperature or humid environments, high temperature and moisture-proof optical cables should be selected to ensure the stability of their transmission performance.
