How to install Black Box SFP, 1250‑Mbps Fiber with Extended Diagnostics

• Power down the host device (switch, router, or media converter) before inserting or removing the SFP module to prevent damage from static or misalignment.
• Insert the SFP module into the eligible SFP port until it seats firmly with a light click, ensuring the connector is oriented correctly for the chassis and slot type.
• Connect a 1310 nm single‑mode fiber optic cable with LC connectors, aligning the transmit and receive orientations to match the corresponding ports on the network equipment.
• Power on the device and verify the SFP link status through the device’s management interface or LED indicators. Confirm that the port negotiates at or near 1250 Mbps where supported.
• Access the management tools to review extended diagnostics and ensure parameters (temperature, wavelength, fiber length, and bit rate) reflect expected values for a healthy link. Schedule routine checks to monitor drift, aging, or thermal changes over time.
