You must deploy standard single-mode fiber (SMF G.652D) for full 80km transmission performance. Multimode fiber cannot reach this distance. Use duplex LC single-mode patch cords. Proper polarity is required for bidirectional transmit and receive; reversed polarity will cause link down. We suggest testing fiber attenuation before deployment. The module works well on dark fiber for ISP backhaul and campus inter-building links. By

LS-SM552G-80C is commercial grade operating at 0°C ~ +70°C, while LS-SM552G-80I supports industrial wide temp -40°C ~ +85°C. The C variant suits indoor data centers, campus rack rooms, climate-controlled utility cabinets. For uninsulated outdoor cabinets with extreme hot/cold fluctuations, we recommend the industrial 80I model to avoid temperature-triggered LOS or TX fault warnings. Both share identical 2.5Gbps speed, 80km SMF reach, 1550nm DFB+APD optics and DOM monitoring. By
