In order to ensure that SFP modules (and all optical transceivers for that matter) continue to perform at their optimal level, it is important to follow proper maintenance procedures. This article offer a few basic tips to help in that regard.
Cleanliness
One of the leading causes for SPF performance degradation is dirty connectors. Any dust or dirt particles that infiltrate the optical connector can increase attenuation (loss of light) and therefore negatively impact the device's performance. To avoid this you should always make sure that:
All optical connections are covered with dust caps when not in use
Never touch the ends of optical connectors with your fingers
Use proper fiber inspection and cleaning procedures before plugging fiber cables into the SFP
Insertion & Removal
When inserting or removing an SFP device from its port, it's important to follow proper procedures. Here are a few tips to keep in mind:
Do not remove and insert the SFP more often that necessary as repeated removal and insertion can shorten the device's useful life
Ensure that you only insert the SFP in the correct port; trying to insert and SFP into the wrong port can damage not only the SFP but also the host port
Make sure the SFP is aligned correctly and in the right direction before inserting into the port and never forcefully push it in
Disconnect all fiber cables from the SFP before inserting or removing the SFP
ESD Protection
All SFP optical transceivers are sensitive to static discharges. Therefore, it is very important wear an ESD-preventive wrist band connected to the chassis or any other comparable grounding device at all times when handling the SFP modules.
