How to Install Accortec 1000BASE-LH40 SFP Module

• Power down or prepare for hot-swapping according to your device’s maintenance procedures. In many modern network devices, SFP modules can be replaced without a full power cycle, but always follow vendor recommendations to minimize disruption.
• Remove the dust cap from the SFP port and inspect the connector area for cleanliness. If needed, clean the optical surface with an approved fiber-cleaning swab to prevent contamination that could degrade link performance.
• Orient the LH40 SFP so that the keyed edge aligns with the slot’s notch. Gently slide the module into the SFP port until it clicks into place and is firmly seated. Do not force the module or bend the fiber cables during installation.
• Attach the fiber pair using an LC duplex patch cable. Confirm that the patch cable is clean and free of cracks or damage, then connect one end to the SFP module and the other end to the corresponding transceiver or fiber termination point at the remote site.
• Power on the device (if required) and verify link status on the switch or router. Check the front-panel LEDs and the management interface to confirm that the port is up at 1 Gbps and that there is a valid link. If available, read the DDM values to ensure TX/RX power and temperature fall within expected ranges and adjust cabling if necessary.
