As an important accessory in the field of optical communications, optical modules realize the conversion of optoelectronics and electro-optics, connect to optical fibers and carry the rapid conversion and transmission of data traffic. Therefore, it plays a vital role in the entire network system. Although optical modules do not require complicated debugging and configuration like network equipment such as switches and servers before they can be used, our technicians still need to strictly follow the operating procedures during use, otherwise it will cause some inconveniences. Necessary trouble.
Recently, a customer reported that they purchased a batch of 10G multi-mode optical modules and used them on a well-known brand switch. After plugging the modules into optical fibers and connecting them to the equipment, UP/DOWN oscillations occurred multiple times. Customers are worried that the optical module is incompatible with the equipment, causing the equipment to report error alarms. According to technical analysis, the optical module has been tested for compatibility before leaving the factory, and according to on-site feedback, only one port repeatedly oscillates. If there is a compatibility problem with the same batch of modules, then all ports should not be able to function normally.
Therefore, compatibility issues can be eliminated. Finally, after repeated technical investigations, the cause of the oscillation was identified: the on-site optical fiber was old and there was dust in the optical fiber socket, which caused the optical fiber port of the optical module to be contaminated, eventually causing a oscillation alarm on the equipment. It can be seen that when using optical modules, you need to pay attention to protecting the optical port to avoid contamination.
So how to protect the optical port? The following instructions are for reference.
1. Maintain a clean environment: Make sure the area where these optical modules are installed and used is kept clean and try to avoid the accumulation of dust and dust. Clean the surrounding area and equipment regularly, either with a vacuum cleaner or a cleaning cloth.
2. Use dust-proof plugs: When the optical module or optical fiber module is not inserted into the device, please do not remove the dust-proof plugs of the optical modules. The dust-proof plugs are used to protect the ports and interfaces and prevent dust from entering.
3. Wear gloves: When handling optical modules or optical fibers, try to wear dust-free gloves to avoid dirt and grease on your fingers from contaminating the equipment.
4. Clean the module regularly: Use a non-woven cloth or special optical fiber cleaning paper, dip it in alcohol, and gently wipe the end faces of the optical module and optical fiber connector to ensure that they are clean and dust-free. Be careful to avoid wiping with particles that may scratch or stain the optical fiber.
5. Proper installation: Install the optical module and fiber optic cable correctly to ensure that they are stable, fixed and not easily contaminated by external dust.
6. Avoid frequent disassembly: Try to avoid frequent disassembly and insertion of optical modules and optical fiber connectors, because each disassembly will increase the risk of dust entry.
In short, maintaining a clean environment, using dust covers correctly, wearing gloves, cleaning modules regularly, and installing them properly can help minimize dust contamination of optical modules and fiber optic modules.
