A:
The module requires standard 9/125μm OS2 Single Mode Fiber (SMF) terminated with a Duplex LC connector. For bench testing or links under 30km, we strongly recommend adding a 10dB to 15dB optical attenuator on the RX side to prevent the high-power 1550nm DFB laser from saturating or damaging the sensitive PIN receiver.
