Before using the optical module, you should understand the taboos and correct operation methods of using the optical module. Since the optical module itself is relatively compact and fragile, any irregular operation may cause hidden damage or even permanent failure of the optical module hardware. In fact, it is very simple to install and remove the optical module. This article will tell you everything about installing and removing optical modules.
Before installing or removing an SFP, you should read the terms below
- High-frequency plugging and unplugging of SFP modules will shorten their service life. Therefore, in addition to normal operation and maintenance and hardware upgrades, try not to plug and unplug optical modules.
- Disconnect fiber optic cables before removing or installing SFP modules. Do not directly install or remove the optical transceiver that is still in the optical cable link state, it may damage the module. The correct way is to first unlink the optical module and the optical cable, and then connect the optical module.
- After removing the fiber jumper, insert a clean dust cover over it to protect the end face of the module. Make sure to clean the connectors of the fiber jumper connectors before reinserting them into the optical ports of another SFP module. Avoid dust and other contaminants from entering the occurrence and receiving ports of your SFP module, otherwise the optical components will limit their transmit power or receive performance when they are blocked by dust, and will seriously burn the module.
- All PCBs are at risk of being struck by static electricity, and transceivers are also sensitive to static electricity, so always make sure to use an ESD wrist strap or similar grounding device during installation and removal.
Preparations before installing or removing optical modules
- Wrist strap or rubber gloves to prevent electrostatic breakdown.
- Fiber end face cleaning tool.
- Pull out the fiber jumper beforehand.
How to plug an SFP Optical Module
You should know SFP+, SFP28, QSFP+, QSFP28 transceiver modules are all referred to as hot-pluggable modules. All of these modules’ installation and removal can follow below simple steps.
- SFP+, SFP, QSFP, SFP28, and QSFP28 modules are all hot-swappable port modules. You can install and remove modules without powering down the device.
- Wear your rubber gloves and ESD wrist strap.
- Do not remove the light hole dust plug before inserting the SFP+ into the designated port. To avoid eye damage caused by laser.
- Align the orientation and slide the transceiver into the port. Note that the port identification will have an arrow, which corresponds to the direction of the optical module.
- Remove the dust plug from the SFP module hole and connect the network interface cable to the module.
- Check the port status LEDs. If the LED turns green, the target device is linked. If the LED is not lit, make sure the target device is powered on before troubleshooting.
To Remove an SFP+ Optical Transceiver Module
Wear an anti-static wrist strap and rubber gloves.
Disconnect the fiber optic cable or network copper cable from the transceiver. Then reinstall the dust plug onto the SFP transceiver. The same is true for the connector of the optical fiber jumper.
Pull out the pull ring of the optical module, keep the angle parallel to the port and pull out the optical module.
Put the removed transceiver in an antistatic bag.
The removal of the transceiver should be done according to different latching mechanisms:
For Mylar/Pull Tab Latch Transceivers
Gently pull down on the tab until the transceiver disengages from the receptacle connector, then pull the transceiver straight out. Do not twist or pull the Mylar label as you may remove it from the transceiver.
For package lock transceivers
Pull the strap buckle outward to eject the transceiver from the device port. If the bale buckle latch is blocked and you cannot open it with your index finger, use a small flathead screwdriver or other long, narrow tool to open the bale buckle latch. Grasp the transceiver with your thumb and forefinger, and gently and carefully slide it out of the port.
Latch Transceiver for Actuator Button
Press down on the tab directly in front of the SFP transceiver, and when it clicks, the latch mechanism partially ejects the transceiver from the port. Using the pull tab, carefully pull the transceiver straight out of the port socket at a horizontal angle.
For sliding latch transceivers
Before pulling out the SFP module, you must eject the SFP module by pulling down on the tab. Pulling out the optical module forcibly will damage the optical module and device ports.
