📡 One comment completely changed the direction of a networking discussion this week.
He said:

👉 Before replacing SFPs, engineers should first check:

• DOM/DDM values
• Tx/Rx optical power
• temperature
• voltage
• bias current
• warning/alarm thresholds
• switch logs

📡 Why Some “Optics Problems” Are Not Actually Optics Problems
❗ The symptoms:
• Packet loss across all ports
• Links randomly dropping
• Auto-negotiation issues
• Some devices couldn’t even detect link
