How to Install ATEN Fiber Single-Mode 1.25G SFP Transceiver Module

• Power down the device containing the SFP slot or ensure the device supports hot‑swap, per vendor guidelines, before inserting or removing the transceiver.
• Open the SFP slot cover or cage as required by your switch, router, or media converter, and align the transceiver with the slot’s keyed edge. Gently push the 2A‑137G into the slot until it clicks into place and remains securely seated.
• Connect a compatible single‑mode fiber cable with an LC duplex connector to the transceiver. Verify the cable polarity and path so the transmit and receive fibers align correctly with the corresponding ports on the other end.
• Power on the device (if applicable) and monitor the status indicators or management interface to confirm link establishment. A steady link LED typically indicates a healthy connection; a blinking or off LED may warrant re‑seating the module or checking fiber integrity.
• Configure the network equipment as needed for your topology (VLANs, trunking, QoS, or other routing policies) and validate throughput with a suitable test tool. If you encounter compatibility issues, verify that the device firmware supports third‑party SFP modules and that the transceiver is recognized in the device’s hardware inventory.
