NOTE:
To perform a loopback operation on a long-haul optical transceiver (40 km or above, that is, 24.86
•
miles or above) by connecting it with a short optical fiber, as shown in
appropriate optical attenuation. Otherwise, the optical transceiver may be damaged.
• The SFP-FE-SX-MM1310-GE supports only an optical interface speed of 100 Mbps.
